DAHUA NVR4104-P-4KS2/L & NVR4116-4KS2/L & NVR4116-8P-4KS2/L

A few years ago, a surveillance system was installed, which was managed locally with a hard disk video recorder, and parents could watch it on TV. Now that my parents are getting older, I also want to take a look at it remotely, but this monitor is too old to support remote management. DAHUA NVR4104-P-4KS2/L PRICE DAHUA NVR4116-4KS2/L price,DAHUA NVR4116-8P-4KS2/L Price I wanted to re-install it, but my friend said that the remote function can be realized by using the networking function of the Dandelion R300A industrial router. , As soon as I heard about the industrial router, I felt that it must be very expensive. I didn’t expect that the price/performance ratio was quite high. After buying a simple installation, it turned out to be a success. I came here to share the experience with you.

Getting to know Dandelion for the first time

The outer packaging of the router is very simple. When we open the box, we can see a very compact router with sheet metal shell, IP30 level protection, lightning protection interface, foot rail installation, and also supports anti-surge, anti-low temperature -20°, High temperature resistance of 70 degrees, this industrial design is indeed very good.

The industrial routers I have seen before are all bulky and rough in workmanship, but this one is very delicate.

Open it to the back, you can see its parameter information, and there are butterfly buckles on the left and right sides of it, which is convenient for installation in industrial scenes.

​Don’t throw away old monitoring, use DAHUA NVR4104-P-4KS2/L PRICE DAHUA NVR4116-4KS2/L price,DAHUA NVR4116-8P-4KS2/L Price to achieve remote management.

There is also a clip on the side, which can be easily fixed to the rail of the cabinet through this clip.

In terms of interfaces, it has two network cable interfaces, one is the WAN/LAN adaptive network interface, and the other yellow is the LAN interface. On the right side are two different power ports, which can be powered by a terminal cable or by a DC adapter.

There are also many interfaces on the other side, the left side is the WiFi antenna interface, followed by the 4G card slot. The metal color in the middle is the ground wire, WPS is a security key for wireless connection, Rst is the reset key, and the far right is the 4G network antenna. The ground wire is very necessary to prevent static electricity, DAHUA NVR4104-P-4KS2/L PRICE DAHUA NVR4116-4KS2/L price,DAHUA NVR4116-8P-4KS2/L Price  avoid lightning strikes, and also play a role in leakage protection.

The front is the display panel, with a dandelion logo on the top, and the product model of the R300A below. When the power is turned on, if we have made the connection correctly, the corresponding LED indicator will be displayed. From top to bottom, they are: system running status, WiFi connection status and 4G connection signal status (there are three bars in the 4G display status, indicating the length of the 4G signal, and the more lights, the stronger the signal strength).

Well, this is our Dandelion R300A industrial router, the last picture of its family, including the power adapter, expansion screws, router host, manual, and two antennas.

DAHUA NVR4104-P-4KS2/L PRICE DAHUA NVR4116-4KS2/L price,DAHUA NVR4116-8P-4KS2/L Price  Connect using

First, insert the SIM card into the router. The router presents 2 4G IoT cards, and the traffic tariff is relatively cheap. The router is fully supported by Netcom, China Unicom, China Telecom, and China Mobile.

Then connect the power to the router device. After the signal light on the front panel lights up, it can be operated. After looking at it, the 4G signal of the router is not bad, and it is still full.

Let’s test the 4G network speed first, download 74Mbps, upload 23Mbps, this speed is still very good, basically the level of 100M broadband.

After turning 4G into WiFi or wired, it is convenient to use, and you can surf the Internet in places without broadband.

Next is its intelligent networking experience, which is even more powerful. Intelligent networking is actually a large virtual local area network. You can remotely access the devices or data of network members. Using this feature, you can turn some local devices into Network equipment. For example, many people have cameras with analog signals. Previously, these cameras were managed locally through a computer or a hard disk recorder, and there was no remote management function, but they can be managed remotely by connecting to this router.

Let’s set up a network first, and create a network on the network management platform.

Start a network name and select a network type.

Add hardware members and software members. The hardware member is the router itself, and the router is added through the SN.

After the addition is complete, the networking is completed.

After the monitoring is connected to the network of the router, the monitoring can be accessed remotely.

Today, if you don’t use this kind of industrial router with intelligent networking function, most of the analog signal monitoring cannot realize the function of remote management and can only be eliminated, but after using this Dandelion R300A intelligent 4G router , the old monitor can shine again. The key is that this router has powerful industrial performance and affordable price. The money to buy a router is more cost-effective than changing a set of monitors.

In order for the network at home to meet my needs as much as possible, I have tossed some routers and switches one after another. Some time ago, I made special preparations for the decoration. I put the network cable into each room, and also installed a camera outside the door.

In fact, these DAHUA NVR4104-P-4KS2/L PRICE DAHUA NVR4116-4KS2/L price,DAHUA NVR4116-8P-4KS2/L Price are all to satisfy their own tossing desires. After all, in the home network, a wireless router can often solve the problem.

In order to toss this network system, I bought a router and an AP during Double Eleven.

The router I bought is TP-LINK TL-R470GP-AC, which is a Poe-powered enterprise-grade gigabit router with AP management, one WAN port and four LAN ports, very small in size.

TL-R470GP-AC has an automatic cleaning function, which can automatically clear the device cache when the network is idle to ensure the long-term stable operation of the network. At the same time, the host network and guest network can be set up to achieve data splitting, which not only facilitates the use of wireless by visitors, but also ensures the security of their own network data.

After establishing a wireless network through multiple APs, the same SSID can be seamlessly roamed in the whole house, which can effectively eliminate the coverage of dead spots.

AC1200 dual-band wireless ceiling AP is generally used in commercial places.

2.4G+5G frequency band signal, dual-band concurrent, wireless rate can reach 1167Mbps.

Built-in dual-band antenna, which is specially designed for ceiling installation, can not only improve the quality of wireless signals, but also reduce co-channel interference and improve transmission new energy.

AC1200 has built-in independent hardware protection circuit. When the AP works abnormally, it can automatically restart without manual intervention to resume normal work.

Standard PoE power supply, installation and wiring are very simple, fat and thin integrated mode, in FAT mode, no need to use AC management, AP can work independently; in FIT mode, used with AC, through AC unified management of AP, AP zero configuration can be achieved Plug and play.

The AC1200 can be installed not only on the ceiling, but also on the wall.

A light cat, a router, a switch, and a power socket plus a lot of network cables are stuffed into the weak current box. It’s a bit crowded. I don’t know if it will overheat in summer. Small temperature controlled fan goes in.

The AP is installed on the ceiling of the living room. This position is basically in the center of several rooms. The actual measurement shows that the signal in each room DAHUA NVR4104-P-4KS2/L,DAHUA NVR4116-4KS2/L,DAHUA NVR4116-8P-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4116-4KS2/L,DAHUA DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L,NVR4116-4KS2/L,NVR4116-8P-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4116-4KS2/L,DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L Price,NVR4116-4KS2/L price,NVR4116-8P-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4116-4KS2/L price,DH-NVR4116-8P-4KS2/L price is not bad.

Considering that sometimes I won’t live here, I installed a camera outside the door. Hikvision’s 2.8mm riot camera for elevators, powered by PoE, is directly connected to the TL-R470GP-AC, a separate one The hard disk video recorder is connected to the switch, which is a very simple but relatively reliable monitoring system.

The configuration is very simple, I won’t say much here, just fill in the account password of the broadband.

This is the connected AP, set the wireless name and password.

Here you can see the current network status and some devices connected to the network.

I am currently connected to some smart appliances, including some lamps and kitchen appliances from Xiaomi, and several Midea air conditioners can also be connected to the network for remote control.

Because they are all very popular network devices, I won’t introduce them too much.

In general, everyone has different needs for the network, and some people do not like to toss, and a network cable can be connected to a wireless router to achieve indoor network coverage. But for people who like tossing and have high demand for the network, they will pull the Internet cable in each room in the room. At this time, it is necessary to choose the appropriate network equipment according to their own needs.

TP-LINK R470 and AC1200 can basically meet my current network needs, and the stability is relatively good. It is enough for my current daily use, especially the PoE power supply of TP-LINK R470 is very important to me.

Hikision (Hikvision) brings an ultra-high-definition home intelligent PTZ camera – EZVIZ C6WI Internet PTZ camera, equipped with 4 million ultra-high-definition lenses, supports 360° panoramic viewing angle of the PTZ, and DAHUA NVR4104-P-4KS2/L,DAHUA NVR4116-4KS2/L,DAHUA NVR4116-8P-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4116-4KS2/L,DAHUA DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L,NVR4116-4KS2/L,NVR4116-8P-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4116-4KS2/L,DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L Price,NVR4116-4KS2/L price,NVR4116-8P-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4116-4KS2/L price,DH-NVR4116-8P-4KS2/L price also supports AI tracking and AI The face recognition technology has also been optimized in terms of functions. The dual-screen mode and the local face recognition function are very user-friendly, and home users who need a clearer and smarter experience monitoring can pay attention.

EZVIZ C6WI is small in size and exquisite in design. The base is made of silver-gray anodized aluminum alloy. It looks very textured and can be placed or hoisted for fixation. Support 360° panoramic viewing angle, can rotate up, down, left and right, horizontal field of view 360°, vertical field of view up 120°, vertical field of view down 5°.

Compared with 1,000,000, 2,000,000 pixel surveillance cameras on the market, this EZVIZ C6WI uses a high-sensitivity sensor professional lens, with 4 million full HD image quality and a maximum resolution of 2560×1440.

Internally upgraded high-performance AI smart chip, equipped with 1.0T surging computing power, higher intelligent recognition rate, and supports AI tracking, when a human figure or face appears in the monitoring range, it will be very accurate identification and automatically focus on the humanoid area to track and shoot, Effectively reduce false positives and warnings. In addition, when tracking close-ups, the monitoring screen will automatically focus and zoom in by 4 times, and the small window will also display the screen in full screen. This dual-screen mode is more intuitive and efficient.

In addition to the powerful cloud-based intelligent face recognition function, in fact, the local built-in face recognition function can quickly recognize faces even if the network is disconnected. At the same time, 30 face data can be stored locally, and face information can also be compared. When the face information of family members is stored, only the information will be pushed after the monitoring is found, and the alarm will not be reported, while the stranger’s camera will alarm + send information at the same time. to humanization.

In other respects, it supports dual-band wireless, two-way calling, H.265 intelligent encoding, high-definition video transmission, and user-friendly one-key masking function. The stored video is encrypted with financial-level security, and the cloud storage server has obtained ISO27001 certification, so there is no need to worry about privacy leakage. In addition, in addition to local TF card storage, it also supports cloud storage, and can also be used with large-capacity hard disk video recorders.

A few years ago, I replaced the TV with a projector and built a giant-screen video room. However, the display effect and intelligent system at that time were too difficult to describe, and it was replaced by a traditional TV within a few months. Because I’m used to watching dramas and variety shows on Aurora TV, I used Tencent Aurora Box 3 Pro to replace the smart system that comes with the TV.

However, the projector has always been my favorite. I like to toss and I have recently started to build a projector. I have to say that the current projectors are really much better. In addition to the good display effect, various intelligent operations have also given me a new experience. After all, “one inch is big, one inch is cool”, the projector’s natural giant-screen audio and video experience is unmatched by LCD TVs at the same price.

My projector is the latest DAHUA NVR4116-4KS2/L. It is not only outstanding in terms of hardware configuration, DAHUA NVR4104-P-4KS2/L,DAHUA NVR4116-4KS2/L,DAHUA NVR4116-8P-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4116-4KS2/L,DAHUA DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L,NVR4116-4KS2/L,NVR4116-8P-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4116-4KS2/L,DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L Price,NVR4116-4KS2/L price,NVR4116-8P-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4116-4KS2/L price,DH-NVR4116-8P-4KS2/L price viewing effect and intelligent system, but also the built-in genuine Tencent START cloud game can play 3A masterpieces with one click. Whether it’s a giant screen video or a fierce battle game, it seems to have grown on the needs of my playful dad.

The unboxing of the DAHUA NVR4116-4KS2/L can be said to be quite “environmentally friendly”. It only has the projector host, power cord and manual. It would be nice to have an HDMI video cable. However, there are still some small surprises, that is, an additional Tencent START customized Beitong Cloud gamepad is included, which looks and feels quite good.

Excellent Perimeter Protection for Enhanced Alarm Accuracy
With the excellent perimeter defense purpose, the Dahua NVR4000-I Collection can significantly decrease false alarm and provide higher accuracy functionality to end-users. The potential of the new NVRs to filter out fake alarms triggered by animals, rustling leaves, brilliant lights, and so forth. permits secondary recognition of the targets, therefore enhancing alarm accuracy. Besides, the NVR4000-I series is capable of examining targets based mostly on deep understanding algorithm to differentiate folks and vehicles, consequently making retrieval far more productive.

Superior Face Recognition with Several Apps
The AI-run face recognition engineering guiding these items enjoys a higher status in the industry, winning numerous initial prizes in global competitions. Becoming acknowledged on efficiency for both effectiveness and precision, Dahua Confront Recognition delivers true-time facial evaluation by pinpointing, capturing and recording faces with powerful metadata. Combined with configurable multiple face databases, widespread and stranger mode could alarm for suspects on blacklist, allowing passing for authorized folks on whitelist, also notify for approaching of strangers.

DAHUA NVR4116-4KS2/L is a square black box with a 7-lens projection lens on the front, which can provide 1300 ANSI high-brightness images, the output resolution is 1080*1920, and supports 8K (7680* 4320) decoding in Ultra HD resolutions. Such performance is inseparable from the computing power of the processor, and the built-in 12nm Amlogic T982 flagship chip with 4GB+64GB top-level configuration is the core configuration that allows the DAHUA NVR4116-4KS2/L to be so willful.

The side of the DAHUA NVR4116-4KS2/L is also surrounded by a circle of honeycomb holes. In addition to the heat dissipation effect that is easiest to think of, it is more important for its sound effect. The two-way 10W×2 audio system provided by JBL supports Dolby DOLBY Audio and DTS-HD dual sound effects. This kind of sound effect does not need to be matched with other speakers at all.

6. Storage method

Most cameras on the market today support SD card storage and cloud storage.

The SD card generally supports the size of 16G-128G (some brands can support up to 256G). Personally, I feel that 32G is almost enough. Take my 3-megapixel camera as an example, 24 hours of uninterrupted video recording, 32G memory card can probably record For 3 days, if you only record a 10-second short video of the alarm, it will not be a problem to record it for several months.

Cloud storage is basically charged, but some brands will give free 10-second short videos for several days of alarm, and users can choose according to their needs.

storage method storage method

It is worth mentioning that many cameras support NAS storage, which greatly increases the time for recording video.
7. Installation method

The installation method of the camera is mainly divided into positive installation and reverse installation.

installation method installation method

Cameras that support flip-chip will be equipped with mounting brackets, and the operation is very simple. After the installation is complete, set the screen to flip 180° on the camera, and it can be used normally.
8. Lens shading

Nowadays, surveillance cameras are basically connected to the Internet, so privacy issues at home must be paid attention to. However, many cameras nowadays have the function of physical lens shielding. Users can shield the lens as needed without worrying about privacy being leaked.

lens shading lens shading

The interface on the back is also relatively rich, from left to right are SPDIF digital audio interface, USB 2.0, USB 3.0, HDMI 2.1, LAN network port and DC IN power interface. The 48Gbps HDMI 2.1 interface is fully compatible with the 8K60Hz & 4K120Hz output specifications of PS 5 and Switch, and the USB 3.0 with a reading speed of 640 MB/S can also easily play 4K Blu-ray sources of 30 to 40 GB. Such compatibility allows me to connect various devices without any worries.

Next is the transformation of the projector environment. As the saying goes, “a good horse is equipped with a good saddle”. I specially matched the DAHUA NVR4116-4KS2/L with an 80-inch picture scroll optical screen S1 from Pfister. Compared with ordinary screens or anti-optic fiber cloths, the performance of optical screens in terms of color reproduction, clarity, brightness, contrast, etc. DAHUA NVR4104-P-4KS2/L,DAHUA NVR4116-4KS2/L,DAHUA NVR4116-8P-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4116-4KS2/L,DAHUA DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L,NVR4116-4KS2/L,NVR4116-8P-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4116-4KS2/L,DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L Price,NVR4116-4KS2/L price,NVR4116-8P-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4116-4KS2/L price,DH-NVR4116-8P-4KS2/L price is much better.

Another important reason for matching this optical screen is that it is easy to install, just stick and suck, without the need for an electric drill to drill hard. Draw the vertical line according to the size, and then use the projector to project the installation guide color block diagram, then paste the magnetic suction patch corresponding to the color block, and finally attach the optical screen magnetically.

After a while, the projector viewing system in the bedroom was completed. Because the projector bracket was temporarily unavailable, the projector was temporarily placed on the back of the bed. The height of the optical screen is exactly the most comfortable height for lying down or lying down. Next, I will start to formally experience this magical little black box, and I still have some expectations in my heart.

After turning on the DAHUA NVR4116-4KS2/L, the picture can automatically fill the screen, and the definition is just right. “Huh? Why don’t you need keystone correction and focal length calibration?” This is because the intelligent system of DAHUA NVR4116-4KS2/L supports auto focus, auto keystone correction and auto entry. You can automatically enter the best viewing screen with one key. This automatic intelligent adjustment is really easy~

PTZ

Generally speaking, PTZ cameras have dual motors, which can rotate freely up and down, left and right, and the angle of rotation is different. For example, some cameras support 360° horizontal rotation and 110° vertical rotation, while some cameras support vertical rotation. reached 143°.

All in all, the more the angle of the gimbal is rotated, the larger the angle of view of the camera.
4. Voice call

Voice calling is also a basic function of cameras. Most cameras on the market now support voice calling, which is convenient for communicating with the elderly and children at any time.

Voice calls are divided into one-way origination and two-way origination.

One-way initiation means that only voice calls can be initiated from the mobile app to the camera; while two-way initiation means that there is a button on the camera, click that button, and the mobile app on the other end will receive the call. Children at home alone can also contact family members outside.

Two-way initiating a voice call Two-way initiating a voice call

Today’s two-way voice calls can even be made directly by a child’s gesture, which is very convenient.
5. Motion tracking, sound detection, face recognition, route cruise, sound and light alarm

These are the housekeeping functions of the camera, not every camera has it. Generally, the more expensive the camera, the more complete the functions.

The DAHUA NVR4116-4KS2/L is also equipped with the AI ​​​​color vision function. The display effect can be greatly improved through the frequency division of PQ and video. In other words, the color display is fuller and more targeted. In Qian Yuankai’s standard screen test chart, whether it is color performance or tone level restoration, its performance is even similar to that of a ipc-hfw5442t-ase display.

Below I play Eason Chan’s “The Lonely Brave” MV. In the blood-filled music and cool punk animations, you can find that no matter it is the fast-changing picture or the texture restoration of the skin color of the characters, the audio-visual double enjoyment brought by the giant screen projection , are still quite shocking.

In addition to supporting dual decoding of HDR 10+ and HLG display standards, DAHUA NVR4116-4KS2/L also supports MEMC anti-shake technology in order to cope with the screen tearing caused by large-scale movie viewing. When watching fast-moving ball games or games, the smear phenomenon can be greatly improved and alleviated. Is there any good news for fans to be ecstatic?

Unconsciously talking about this, many people may be wondering what the gaming experience of Tencent START cloud games is like? DAHUA NVR4104-P-4KS2/L,DAHUA NVR4116-4KS2/L,DAHUA NVR4116-8P-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4116-4KS2/L,DAHUA DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L,NVR4116-4KS2/L,NVR4116-8P-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4116-4KS2/L,DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L Price,NVR4116-4KS2/L price,NVR4116-8P-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4116-4KS2/L price,DH-NVR4116-8P-4KS2/L price connects to Tencent’s cloud game server through the Internet, and then can play a variety of the most popular 3A masterpieces with one click without the need to download games. START Cloud games do not depend on the performance of hardware, nor do they take up hard disk space and complex settings, and there are still a lot of games in it~

Combined with Beitong’s customized cloud gamepad, it feels like playing console games. The following is the process of playing games in the START cloud game. Whether it is a 3A shooting masterpiece or a racing car, the game experience it brings is no different from that of a PC or a game console. It really answers the sentence “The bigger the screen, the more fun “.

The built-in intelligent operating system of DAHUA NVR4116-4KS2/L is the popular cloud audio-visual Aurora TV OS. I am also used to using cloud audiovisual Aurora TV, so I bought Tencent Aurora Box 3 Pro, but it is useless now. For a DAHUA NVR4104-P-4KS2/L,DAHUA NVR4116-4KS2/L,DAHUA NVR4116-8P-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4116-4KS2/L,DAHUA DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L,NVR4116-4KS2/L,NVR4116-8P-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4116-4KS2/L,DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L Price,NVR4116-4KS2/L price,NVR4116-8P-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4116-4KS2/L price,DH-NVR4116-8P-4KS2/L price platform or TV app, it’s simply dad-level.

There are three exclusive viewing modes: standard, children, and elders, and the content will be adjusted for different groups of people. For example, the children’s mode will show more cartoon animation and learning knowledge, and the elder mode will only keep the frequently watched content and display larger fonts. In addition, the main interface of the waterfall UI and the free installation of various third-party TV apps are also important reasons for making the DAHUA NVR4116-4KS2/L an audio-visual entertainment center.

Brightness is often the core indicator for choosing a projector. The DAHUA NVR4116-4KS2/L’s 1300 ANSI brightness is the level that should be in the ipc-hfw3841e-as. Thanks to AI Vision and HDR 10+&HLG color display decoding, the color reproduction of DAHUA NVR4116-4KS2/L in low light conditions is more realistic. Coupled with the 10W×2 JBL two-way audio, the audio-visual experience of watching movies can be immersed in it.

The display effect of DAHUA NVR4116-4KS2/L is very good even when the curtains are not drawn during the day. The following is the change and contrast of the display effect in the process of dark field to bright field. At this time, the importance of the optical screen is reflected. Even in a bright environment, the DAHUA NVR4116-4KS2/L can still display pictures with rich colors.

The sound and light alarm means that when there is an abnormal situation in the screen, the camera will emit a flash and a voice alarm sound to deter intruders.

During the experience, I also found some interesting small functions of DAHUA NVR4116-4KS2/L, and now I will share with you. It was the first time to watch the young lady dance on such a big screen, and that feeling was quite special.

Just mentioned that DAHUA NVR4116-4KS2/L has a built-in two-way 10W×2 audio system provided by JBL, and supports Dolby DOLBY Audio and DTS-HD dual sound effects. How can such a good sound effect be easily wasted? Therefore, DAHUA NVR4116-4KS2/L can also be switched to audio mode, which is equivalent to an additional audio system of a thousand yuan machine, haha

After fully experiencing the DAHUA NVR4116-4KS2/L, I think its performance in the price range of 3,000 yuan is quite sincere. Amlogic T982 combined with 4G+64G hardware strength, AI real color vision image quality combined with JBL audio audio and video experience, cloud audio-visual Aurora TV OS and intelligent interaction of START cloud games, all make this DAHUA NVR4116-4KS2/L cost-effective .

1080P and 2K1080P and 2K

Personally, it is recommended to choose a monitor with a higher resolution. Above 1080P, the worst should be 720P. No matter how low it is, it is really hard to see.
2. Night vision function

Night vision is important!

In line with the principle of the camera to watch the home and the hospital, you can even observe the child’s sleep at night, whether they have the habit of pushing a quilt, etc. The quality of the night vision function determines whether a clear picture can be captured at night.

Nowadays, the night vision of cameras is mainly infrared night vision, which is divided into black and white and full color, and full color is also divided into low light full color and star full color.

Black and White and Full Color Black and White and Full Color

As the name suggests, low-light full-color is that the camera can shoot colorful pictures even when there is low-light indoors, while starlight full-color goes a step further. Even if there is only faint starlight in the room, it can shoot full-color with extremely high pixels. image quality.
3. PTZ

The gimbal is the angle of the camera that can be adjusted. Simply put, a camera with a gimbal is like sitting on a platform and can be rotated everywhere.

“No one is perfect, and no machine is perfect.” DAHUA NVR4116-4KS2/L still has room for improvement, such as: there is no standard HDMI video cable, no screen cleaning cloth for lens cleaning, no ICCTVZONE self-operated store The matching curtains and brackets can be purchased, the brightness does not reach 2000 ANSI, there is no white color matching style, there is no karaoke mode, etc. If the goose factory can see my suggestion, is it inspired by the development of the Aurora Projector P3? Woolen cloth?

Regarding the purchase suggestion of DAHUA NVR4116-4KS2/L, I think it is more suitable for the following people:

1. It is the first time to build a giant-screen audio-visual entertainment room centered on the projector, plus the cost of the curtain and bracket, the overall budget can be controlled within 4,000 yuan. Moreover, the configuration of DAHUA NVR4116-4KS2/L will not become slower and be eliminated in three to five years.

Fluorite Fluorite

The brand worth mentioning is EZVIZ. After all, EZVIZ belongs to Hikvision’s security life service brand, and Hikvision is the industry benchmark in the surveillance industry, so EZVIZ is also the big brother of home surveillance cameras.
This camera has 4 million pixels and a resolution of 2.5K. It has two-way voice calls, humanoid detection, sound and light alarm, intelligent tracking, motion detection and many other functions. The pan tilt angle is 360° horizontally and vertically. The rotation angle is 143°, and the field of view is quite large.

The night vision function of the camera is low-light and full-color, and the clarity at night is extremely high; in terms of privacy, it supports physical shielding of the camera. As long as the user sets the parameters, privacy issues can also be guaranteed.

It is worth mentioning that this camera also supports playing children’s songs, telling stories, and reading picture books. Just open the app and you can order it at any time. You can basically find everything that children like to listen to. It can be called an artifact to coax babies.
In fact, there are still many high-profile cameras. After all, the stack configuration is not limited to the upper limit, but for home use, on the one hand, there is no need to buy such a high-profile camera, as long as the function is available; on the other hand, the higher the configuration, the higher the price Expensive, with a limited budget, it is our original intention to buy the most “value” camera.

A colleague of the subsidiary of the group asked me to help me choose a camera to be used for monitoring in the computer room. Because his leader asked to reduce the operating cost of the department, it actually meant that it was impossible to buy a professional-level monitoring camera, but he also hoped that the camera would support the voice of both parties. For the function of calling, the WiFi of their subsidiary’s computer room prohibits mobile phone access for security reasons (it is said to be used as a surveillance camera in the computer room to avoid information security risks: the Honor Little Sentinel 1080P smart camera starts with the experience), the communication of the three major operators The signal covered by the base station is too weak, so that the computer room cannot access the Internet and make calls. Colleagues who go to the computer room need to go outside the company’s channel every time before they can make calls and send WeChat messages.

2. For families with children who need to take online lessons frequently, compared with traditional LCD TVs, projectors have no radiation hazards due to the imaging principle of diffuse reflection display images. It is healthier for children’s eyes, and it will not be dry and astringent when studying for a long time.

3. For students who rely heavily on the cloud audio-visual Aurora APP, Tencent Video Super VIP can log in to four devices at the same time, including TV, tablet, mobile phone, and computer, to seamlessly follow dramas and variety shows, and the whole family can enjoy a silky movie viewing experience without advertisements.

I had the idea to buy a home surveillance camera.

On the one hand, it is impossible for young people to stay at home all the time. There are usually old people and children at home. When the old people get older, it is a hidden danger in itself. In addition, they have to work for the children. There is a surveillance camera that can see the old people and children at any time. The dynamic of the child can be taken care of in time.

Multiple uses of home cameras Multiple uses of home cameras

On the other hand, after the installation of surveillance cameras, the safety of the home is also guaranteed to a certain extent. After all, the cameras can be connected to the Internet 24 hours a day and can also be stored in the cloud. Whether it is going out or on duty in the middle of the night, the camera can play a good anti-theft effect. .
camera function

Today’s technology is becoming more and more developed, and cameras are no exception, and their functions are becoming more and more powerful.
1. Resolution.

Today’s home surveillance cameras on the market, under normal circumstances, have a minimum of 2 million pixels, known as 1080P resolution; higher ones, ranging from 3 million pixels to 5 million pixels, but more than 3 million pixels basically claim to have 2K resolution rate.

Motion tracking means that when the camera sees a moving object within the line of sight, the gimbal will automatically rotate and shoot in the direction of the object’s movement, capture and record real-time dynamic information, and send a pop-up window to the phone The app can play a good anti-theft effect, and it can also more conveniently check the child’s dynamics.

mobile tracking mobile tracking

Sound detection is similar to motion tracking. When the camera hears abnormal noises in the room (such as broken glass, children crying, etc.), the gimbal will also rotate in the direction of the abnormal sound, and send a pop-up window to the mobile app, effectively avoiding safety. the occurrence of the accident.

Many brands of cameras have also added a “home mode” or “timed lens masking” to make the camera safer to use.
camera brand

When buying a camera, be sure to choose a big brand.

On the one hand, the quality of the big brands is better, and the after-sale service is guaranteed; on the other hand, the current cameras are basically connected to the Internet, and all rely on the mobile phone app to operate. If the brand is too small, the app will go offline and the camera will be useless. , see nothing.

At present, domestic sales are relatively good, mainly from several brands such as EZVIZ, Xiaomi, 360, Lecheng, etc., and brands such as Huawei, Lenovo, tplink, Qiao An, and Chuangmi Xiaobai of the Xiaomi ecological chain also do it. Pretty good.

Security can be understood as an acronym for “safety precaution”. According to the interpretation of modern Chinese dictionaries, the so-called safety means no danger, no harm, and no accidents; the so-called prevention means being prepared for, guarding against, and precaution means being prepared to deal with an attack or avoid being victimized, and alert means guarding and protecting . Based on the above explanations, we can define security precaution as follows: prepare and protect to deal with attacks or avoid victimization, so that the protected object is in a safe state without danger, damage and accidents. Obviously, safety is the goal, and prevention is the means, and achieving or realizing the goal of safety through means of prevention is the basic connotation of safety prevention.

Home security, as the smart home is getting more and more perfect, the layout is relatively much simpler.
Video Surveillance

To put it simply, the home generally starts from the entrance door, and a monitoring system can be installed. This monitoring system can use relatively professional equipment, or can be replaced by various smart cat eyes and smart doorbells.

When I was decorating, I took into account the monitoring outside the door. I specially arranged a network cable to go out, powered by POE, and installed professional cameras to monitor the area from the anti-theft door to the elevator door.

Because the scope to be monitored is not large, and I hope that the installed camera is not easy to attract attention, I chose an explosion-proof camera dedicated to elevators, powered by POE, no need to lay a separate power cable, just a network cable to connect to the switch , and then connect the monitoring host to the switch.

Camera + monitoring host, this system is relatively more reliable. The monitoring host is hidden in the home where it is not easy to notice. The built-in 1T hard disk can realize 7*24 hours of loop recording.

If you need simple installation and convenient use, you can directly install a smart cat’s eye, which integrates the functions of the cat’s eye and the doorbell, overcomes the shortcomings of the traditional optical cat’s eye and the potential safety hazards, and increases the role of monitoring. It is currently widely used in It is an upgrade and replacement product of traditional optical cat’s eye for the door of home and high-end hotels. The smart cat’s eye has a memory function. When someone rings the doorbell, they can not only hear the ringtone, see the image on the screen, but also take pictures and videos, so that they can remember the voice and image information of the person who comes. In addition, the electronic cat’s eye also has automatic memory. That is, the detection function, within a certain range, DAHUA NVR4104-P-4KS2/L,DAHUA NVR4116-4KS2/L,DAHUA NVR4116-8P-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4116-4KS2/L,DAHUA DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L,NVR4116-4KS2/L,NVR4116-8P-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4116-4KS2/L,DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L Price,NVR4116-4KS2/L price,NVR4116-8P-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4116-4KS2/L price,DH-NVR4116-8P-4KS2/L price after sensing the human body, it will automatically take pictures and videos, which is a very practical security monitoring function.

I have installed both sets. The smart cat’s eye is easy to install and use, but the storage capacity is limited and sometimes not so stable. The professional monitoring system can be very stable, but the installation requires pre-buried lines, and the purchase cost is relatively higher. higher.

In addition to the smart cat’s eye, we can also install a wireless camera, which is connected through WIFI, and can be stored locally after inserting a TF card, or the video can be stored in the cloud, but now you need to pay extra for stable cloud services. However, this kind of installation is very simple, and only one power supply line needs to be laid.
Even DAHUA has a battery version of the smart camera, which only needs to be installed and fixed, and even the power supply line does not need to be laid out, which is much more convenient and faster, but because it is a built-in battery, considering the standby time, this product It is not a 24-hour continuous recording, but only when a humanoid is detected and a push notification will be recorded.
But just using the gateway to make a warning sound, the deterrent effect is relatively limited. Of course, if there are many DAHUA products at home, you can set up more linkages, such as controlling the DAHUA ceiling light in the living room to turn on, and controlling the Xiaoai speaker to play music, The video shot by the camera placed in the control room is pushed to your mobile phone, so that once a situation occurs, you can detect it in time, and then notify the property or quickly call the police.

The ICCTVZONE human sensor can also be used in this security system. If there is no one at home during the Spring Festival, place this sensor in some important places where people may enter, and then also link the gateway, link the DAHUA ceiling lamp in the living room, and control the Xiaoai speaker. Play music, control the camera placed in the room to shoot video and push it to your mobile phone.
For local tyrants who have a yard or an outdoor terrace at home, the infrared grating detector arming is a very good choice. When an object crosses the detection area of ​​the grating detector, it can quickly trigger an alarm because the infrared beam is blocked. To ensure the safety of the home, this grating detector adopts the beam in the infrared band, which has fewer blind spots and dead spots.
Environmental safety protection

In fact, when there is no one at home, in addition to preventing people from intruding, we are more worried about the safety of gas, water and electricity in the home. This is also an important part of home security.

In fact, DAHUA has a complete set of sensors, which can completely build an intelligent monitoring system.
I made a simple setup using DAHUA’s smoke alarm, gas alarm and flood sensor.

The smoke sensor, the sensor and the gateway are linked. Once the fire is detected, Xiaoyi will shoot a small video and push it to my mobile phone, so that at least I can know that there is an abnormality in the house at the first time, and then notify the property to open the security door of my house with a temporary password. Check inside.

The key component is the ICCTVZONE smoke alarm.
Without considering remote and linkage, use this as an independent smoke alarm, and it can also play a warning role indoors, because the alarm sound is indeed louder. The actual measurement is two meters away. The decibel meter can measure the alarm sound of 90.1dB.

In general, this smoke alarm from ICCTVZONE is quite practical, especially when there are elderly and children at home who need to use heating equipment, if such a device is installed, once an accident happens, at least you can know it right away. Especially when the binding gateway is linked to other smart products, it can remotely alarm, which is at least more reassuring for us who are not at home every day.

There is also an output terminal on the back of the ICCTVZONE natural gas alarm, in which the T+ and T- terminals are capacitive discharge signal outputs, which can be linked to a 12V pulse solenoid valve, so as long as a gas solenoid valve is installed behind the gas meter, and then through the connection The function of automatically shutting off the natural gas after gas leakage can be realized by connecting the line to this alarm.

The other COM and NO terminals are normally open contacts, DAHUA NVR4104-P-4KS2/L,DAHUA NVR4116-4KS2/L,DAHUA NVR4116-8P-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4116-4KS2/L,DAHUA DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L,NVR4116-4KS2/L,NVR4116-8P-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4116-4KS2/L,DH-NVR4116-8P-4KS2/L,NVR4104-P-4KS2/L Price,NVR4116-4KS2/L price,NVR4116-8P-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4116-4KS2/L price,DH-NVR4116-8P-4KS2/L price which can be linked with the exhaust fan to automatically open the exhaust fan after gas leakage to dilute the indoor gas concentration.

When the water immersion sensor is working, when water soaks into the two stainless steel screws of the fuselage, because the water can conduct electricity, the sensor can detect the “water immersion” state. Expand more usage scenarios.

With the help of this sensor, with ICCTVZONE smart socket and solenoid valve, it can automatically turn off the water inflow after water leakage.

The whole logic is that the water immersion sensor detects water leakage and sends a signal to the smart socket, the smart socket is powered on, the solenoid valve is powered on, and the water source is turned off; the water immersion sensor monitors safety, the smart socket is powered off, the solenoid valve is powered off, and the water source is turned on.
Summarize

In general, with the increasing popularity of smart home devices, it is very simple to build a simple home security system.

We use these various cameras, gateways, and sensors to build such a simple security system. The purpose is to grasp the situation at home in real time when people are not at home, and to know whether there is any abnormal movement and whether there is a dangerous intrusion.
