DAHUA NVR4104-P-4KS2/L &NVR4108-4KS2/L & NVR4108HS-4KS2/L

Now monitoring has been involved in all aspects of life, especially in commercial occasions, it is almost necessary, and now the monitoring will be installed by the way in the store decoration. How to install to achieve the best results is more troublesome.DAHUA NVR4104-P-4KS2/L DAHUA NVR4108-4KS2/L DAHUA NVR4108HS-4KS2/L I have been making products for many years. Recently, I have received a lot of inquiries from friends asking about how to purchase optional installations for store monitoring. I just made a small plan in the past two days to give you a simple reference.

The first is to first determine the demand and refer to the budget to formulate a relevant plan. According to the wiring method, it is divided into wired and wireless. The difference is that the stability of the wired is not easily affected by other interference, and requires early wiring; the wireless is relatively free of wiring. The construction is convenient, and basically you can do it yourself. Installation is generally suitable for occasions with few installation points. This kind of DAHUA NVR4104-P-4KS2/L DAHUA NVR4108-4KS2/L DAHUA NVR4108HS-4KS2/L is generally a camera, and then it can be done with a TF card. It also supports voice intercom, alarm, etc., and the installation is also convenient, similar to this.

With the strengthening of people’s awareness of home security, Internet companies represented by Xiaomi and 360 have begun to set foot in the surveillance category. Many products with different shapes and functions have made consumers a little bit more and more attractive, and they don’t know how to choose a good one. . I am sitting in a 4-storey villa and naturally dare not relax. I have tried many different solutions in the past few years, and I have also paid a lot of IQ taxes. When I replaced the hard drive for my NVR recently, I took some footage and shared with you multiple surveillance cameras. The purchasing skills and management ideas of the head environment.
Although the product names launched by those Internet companies are more or less with the word “monitoring”, I think most of them can only be regarded as “webcams” at best. storage security. The TF card inserted into the fuselage has a short storage time, and the data is easily damaged. At the same time, due to the lack of support for the Onvif or RTSP standard network protocol, it is impossible to establish a data connection with the NVR device for relatively safe local video storage. It is often difficult to prove evidence after an accident, resulting in property losses.

It is recommended to buy products from established surveillance industry brands such as Hikvision, Dahua, and Uniview. Although the appearance is ugly and the experience is poor, the performance is stable and the data is reliable. No one bothers to monitor and play every day. For the first time, it is set up and put there to work silently, waiting for the moment when soldiers are trained for thousands of days and used for a while. I use Hikvision EZVIZ’s C3W to be responsible for indoor panoramic views, C6TC to patrol key areas, and C5HC to stand guard in the outdoor yard. PS: The comprehensive index of fluorite is almost worse than that of Haikang, but it is necessary to take into account the appearance when it is placed indoors.
The full name of NVR is network video recorder, and its main purpose is to store the video data of the monitoring head. Whether you need to buy it depends on the number and importance of the monitoring heads deployed at home. One or two is really unnecessary. As for the degree of importance, it depends on the actual situation of each family, including jewelry cabinets and safe areas.

The purchased reference indicators are: monitoring head connection method, BNC video signal, RJ45 network port, WiFi wireless, of which RJ45 is available with or without POE (power supply by network cable), which is matched with the POE monitoring head, and no additional power adapter is required. My home is not convenient for wiring, so I choose WiFi wireless connection; the number of video access channels, an integral multiple of 4, common 4, 8, and 16 channels, just leave a good margin; multi-protocol support, prefer ONVIF and RTSP Multi-protocol products, enabling cross-brand device support.
If you have a computer at home that must be turned on 24 hours a day, such as NAS, scientific computing, soft routing, etc., installing a special monitoring software can save money on purchasing an NVR, but you have to check the working status of the software every few minutes, and don’t be unresponsive. .
If you decide to buy an NVR, you need to use a mechanical hard drive for storage. This work seems simple, unlike games and large-scale applications that test performance, but the 7×24 continuous sequential writing, high temperature and high humidity closed environment put forward strict requirements on reliability. Refine product line. Taking Western Digital as an example, product lines are distinguished by intuitive colors. The product line for video recording is purple, commonly known as purple disk.

The biggest features of Western Digital Purple Disk support 7×24 continuous sequential writing, the annual workload rate is up to 180TB, the average failure-free working time is 1 million hours, the working environment temperature is 0-65 degrees, and the storage environment temperature is -40-70 degrees. A maximum of 16 disks and 64 channels of monitoring storage can be installed in an NVR. Considering that some NVRs are in an outdoor long-term maintenance-free environment, anti-corrosion components are added to the hard disk. For video playback, AllFrame technology improves streaming, helping to reduce dropped frames and improve overall playback.
[NVR replacement hard disk actual combat]

The reason why I chose EZVIZ X5C NVR before is that the self-built WiFi network is connected to the wireless monitoring head, and the upload bandwidth is only used for remote viewing and playback. It does not occupy the resources of the home backbone network and reduces the pressure on the router. The original built-in hard drive, a second-hand Hitachi 500GB that I found at some point, died suddenly after less than 3 years of service.

The new hard drive is a 4TB Western Digital purple drive, which is available in two versions – WD42EJRX and WD40EJRX. The difference is the single-disc capacity and cache. The former is 2TB 256MB and the latter is 1.33TB 64MB, both of which use the popular vertical CMR writing technology. Of course, buy WD42EJRX.

Use the computer’s HDTune test software to see what is the difference between the special monitoring disk and the ordinary hard disk. Unsurprisingly, the read and write speeds are both particularly stable, with a fluctuation of only 10MB/s before 3TB, which is similar to SSD performance. Continuous read and write 100MB/s, enough for multi-channel video data writing and playback viewing.

【NVR control interface setting】

The initial self-inspection step after the NVR replaces the hard disk is essential. The success of the proof after an accident depends on the key video frames. As expected, the quick test of S.M.A.R.T and bad sector detection of the 4TB Western Digital purple disk passed smoothly.

Enter the video related settings, and confirm whether the key options such as 1080P resolution, variable high bit rate, 30-day expiration deletion, all-day video recording, and rolling storage are correct.

For privacy reasons, we only show you the effect of 3-channel monitoring. The NVR outputs the output to the TV through HDMI, and plays the content captured by the monitoring head in real time. I use the TV only as a means to confirm the working status of the hardware every three to five, and the viewing and playback are still performed on a more convenient mobile phone or computer.

If you need to save long-term recordings, it is recommended to use a video recorder. The specific hard disk size will be discussed below. The wired one needs to measure and calculate the line distance, what kind of switch, video recorder, hard disk and so on.

The following is the wired solution I made by myself. 4 cameras are needed to monitor the main areas on site. The recording time is not less than 1 week, to ensure that the picture can be clearly seen at night, and support mobile phone preview and alarm push. According to the situation, the next step is to select the appropriate equipment. Considering the convenience of wiring, the POE solution is selected. One network cable can solve all transmission problems. The camera is a Hikvision 2 million POE infrared barrel camera, which is basically a relatively cost-effective one.
It is also H.265 encoding, which can be connected to network cameras conforming to ONVIF, RTSP standards and many mainstream manufacturers;
Support the preview, storage and playback of 4 million pixel high-definition network video at most;
Support IPC centralized management, including IPC parameter configuration and upgrade functions;
·Support HDMI and VGA homologous output, the maximum resolution of HDMI and VGA output can reach 1920×1080;

The next step is to choose a hard disk. The time required for storage for 1 week = the daily storage capacity of a single camera * the number of roads * the number of days = 23G*4*7=644G, so a 1TB hard disk is enough.

The EZVIZ studio software supporting the EZVIZ monitoring equipment has its own activity detection function. If there is any moving object in the screen, it will be highlighted in red on the time axis, which is convenient for quick viewing. The bound EZVIZ and Hikvision devices can be centrally managed and configured in a unified manner. The disadvantage is that the protocol is closed and the compatibility of cross-brand products is poor.
During the period, I was planning to install monitoring, and I needed to prepare a mechanical hard disk, a video recorder, and several cameras to make a poe power supply monitoring system. Since the hard disk is used as a monitoring storage space, various indicators will not be tested. The mechanical hard disk used for monitoring needs to be paid attention to. Avoid the shingled disk and choose a vertical disk to help the storage and writing. This 4t purple disk, refer to the official monitoring The storage capacity indicator barely meets the current storage capacity demand. This hard drive was insured twice during the period, and finally got 460+, which is a lot cheaper than the 520 yuan when NAS added the last time.
If, in 1965, you had a video recorder in your hand, filmed yourself repeatedly unbuttoning and tying your shirt, and played it on a loop to write a videotape, you might have become the first person in “East Asian video art”. Today, you don’t have to struggle to update your V-log, and you don’t have to show your thighs, punch, or lick your wool in order to cheat some traffic. With this video tape alone, you are waiting for the exhibition invitations of the organizing committees of major art institutions to earn money by standing and wandering around. Isn’t it common for video? rise”

Is this story enticing? But after reading the introduction of this work carefully, I don’t think it is that easy. First of all, in 1965, you must have a Portapak, the first generation of Sony’s portable electronic camera & video recorder. Since the age is too old, after checking the information, I can’t find a regular channel to buy it. Digital collectors, please let me know what the price of this machine is in the secondary market. Let me estimate the price: Can you buy it at 5W? ? ~

For a long time, it is basically impossible to find information about this product on the Internet, and I have searched Ebay and Amazon to no avail. The limited search results tell me that this camcorder, born in 1965, consists of two components: a short film camcorder and a helical scan recorder for recording.
“Button Incident” is Nam June Paik’s earliest surviving and most likely his first video work. The DAHUA NVR4104-P-4KS2/L DAHUA NVR4108-4KS2/L DAHUA NVR4108HS-4KS2/L was created on a day in 1965, when Nam June Paik had just gotten his first Sony Portapak camcorder. Although this work is inadvertently mature in shooting technology, the content is only a simple recording of a repetitive action – the artist buttoned and unbuttoned his shirt.
The artist became the first v-log blogger?

In 1965, Nam June Paik, who was 33 years old, was the same age as the author and bought a Sony camera in New York. At that time, people could only watch TV programs from TV stations, and video production required huge studio cameras to record. , ordinary people can’t buy it at all, and can only passively accept the image. Nam June Paik buying his own imaging equipment is definitely a big deal.

Nam June Paik, born in Seoul, South Korea, in 1932, spent his middle school years in Seoul and Hong Kong, and spent his high school years in Kamakura, Japan. He studied aesthetics at the University of Tokyo. In 1956, Nam June Paik moved to Germany to study European philosophy and modern music, and actively cooperated with contemporary avant-garde artists. By performing radical live performances radically different from the artistic norms and traditions of the time, Nam June Paik shaped his own artist identity. Later, he used new media as a means to embark on a new path of artistic creation. His media art was at the heart of his first solo exhibition, “Illustration of Music – Electronic Television,” in which he presented a television with its internal circuitry modified and manipulated as a work of art.

Nam June Paik was a pioneering media artist who approached various techniques in a creative and experimental way. He believes that artists are on a mission to think about the future and seek better global communication through art. He has been hailed as “one of the pioneers of a new generation of artists who are simultaneously scientists, philosophers and engineers” and “a very special futurist with real genius and vision”.

A digression outside the exhibition:

In the summer of 1969, an artist named Frank Gillette started a video company called Raindance Corporation, which he hoped would become an alternative media think tank; a collection of ideas, publications, videotapes and other resource dissemination tools to provide a theoretical basis for the implementation of social change.
With Sony’s help, Raindance members started making independent videos and trying to distribute cameras to the general public. Once universal, cameras will change users’ social and interpersonal awareness. They also function like weapons, used to challenge the authoritative media order.

Seeing this, the author can’t help but sigh, the pioneering nature of art predicts the world 50 years later! At present, the echo walls and information islands created by major social media platforms make people’s opinions contradictory and divert contradictions. Short videos comprehensively occupy people’s attention and change every general public.
Back to the point

“The rise of the entire East Asian video art represents the entire process of globalization, an evolutionary process. Beginning with the global art network of South Korea, Japan, Europe and the United States involved by Nam June Paik, East Asian artists have Begin to use this culturally non-specific medium to enter new points of exchange and equally complex cross-regional, cross-border networks.

For more than two decades, video art has connected artists around the world, especially Japan since 1968, South Korea since 1978, Taiwan since 1983, Hong Kong since 1985, and China since 1988. China Mainland.

In this exhibition, in addition to the famous Nam June Paik, there are many works worth stopping and thinking about.
Katsuhiro Yamaguchi is a Japanese artist born in Tokyo, Japan in 1928. Since 1974, he has created more than 30 large-scale video installation works. A prolific artist and educator, he founded the groundbreaking art collective “Experimental Workshop” from 1951-1958.

The work uses closed-circuit television to convert Diego Velázquez’s Las Meninas (1656) into several images, which are recorded in close-up. In Gong E’s original work, the relationship between tasks in the picture is very complicated, making it impossible for people to see who is the protagonist, let alone what the painting is trying to express.

【Summary 】

I believe that my sharing will inspire everyone to the home multi-channel monitoring solution. Monitoring equipment should not be too superstitious about the innovative functions advertised by Internet companies, and give priority to products under traditional monitoring industry brands. The security and reliability of monitoring data is the key, save money to buy low-end or blindly pursue high-end

Dahua Technological innovation, a entire world-major video-centric sensible IoT remedy and provider provider, has released its AI NVR4000-I Collection, which includes DHI-NVR4208-8P-I, DHI-NVR4216-16P-I, DHI-NVR4216-I, DHI-NVR4416-16P-I, DHI-NVR4432-I and DHI-NVR4832-I.

Effortless to Use
The model new GUI design tends to make the program easy to function. The flat design and modular design and style presents a much more specialist interface, which offers distinct shade techniques and visual icons that add to the consumer-welcoming experience.

The Spanish artist tried to reveal the structure of power and the process of painting this painting through deconstruction, which is the most discussed element in this masterpiece, and buried an easter egg here, which is Mirror China. Image of king and queen. Notably, Katsuhiro Yamaguchi’s “Miyako” (1974-75) replaces the portraits of the king and queen with a CCTV camera, DAHUA NVR4104-P-4KS2/L DAHUA NVR4108-4KS2/L DAHUA NVR4108HS-4KS2/L exploring symbols of power and surveillance in a contemporary context.
In Western paintings, mirrors often play the function of reflecting the truth of reality. When we appreciate the works of many artists today, often inconspicuous mirrors have hidden mysteries and play a huge role. And this “Palace of the Palace”, in Foucault’s philosophical words, is: a mirror that allows the invisible king and queen to determine a visible court routine.

So let me try to guide you:

If mirrors = focus = centralization, then…
Multiple cameras = unfocused = decentralization, that…

Through the medium of video, Yamaguchi extends the already complex relationship between the viewer and the gaze in Velázquez’s self-portrait as a royal court painter.
Kim Chu Lin, “Lightbulb”, 1975

Jin Qiulin, “Light Bulb”, 1975 Jin Qiulin, “Light Bulb”, 1975

This is a piece I like very much. Traces of time are stored in a medium called video, which is akin to pausing time and replaying the past. It explores several times:

1. The light bulb of the entity is turned on at an interval of 10 seconds, and the monitor screen is the self after 10 seconds, and the virtual and the real alternately discuss the coexistence relationship.

2. The light bulb first recorded on the screen is from 1975, while the light bulb installed in the exhibition is from 2022.

Isn’t Video Common? About “The Rise of Video Art in East Asia”

Past events are experienced in the present moment through a new perspective. Past and present are in constant change and exchange. This work questions the collision, or coexistence, of the past and the present, that is, restoration.

Kim Chu Lin discusses the specificity of light and time in real and virtual media. In this video installation, the video footage records a light bulb on and off at 10-second intervals on a 1:1 scale, with a real light bulb hanging next to the monitor screen. The light bulbs on the monitor screen and the actual light bulbs are lit alternately, in a time-lapse distortion, triggering the harmony and conflict between the recorded time and the perception of real time. By thinking about recording time and recreating in this video installation the light bulb originally photographed in 1975, philosophical and empirical questions about the nature of light—the notion that the speed of light is directly related to time—in this work was called out. The light transmitted from the monitor screen to our eyes is the light that is transmitted in the present, and paradoxically, the light recorded by it is even older, forty-five years ago. ”

Kim Qiulim was born in Sangju, South Korea in 1936, and currently lives and works in Seoul, South Korea. As the founder of Korean experimental art, he occupies an important position in the history of Korean contemporary art.

Rebellious against existing values ​​and customs, Kim Chu Lin’s experimental work ranges from painting, printmaking, sculpture, installation, performance, to land art, video art, and postal art. In addition, he has been involved in the creation of experimental theatre, film, music and dance. In 1969, he created “Relics of Mass Media”, which is considered to be the first postal art work in Korea, and produced “The Meaning of 1/24 Second”, a groundbreaking work in the field of Korean experimental film. He is one of the founding members of the Korean Avant-Garde Association (AG), through which he leads an avant-garde art practice that emphasizes concepts and processes. In the 1970s, he established the “Fourth Group”, an avant-garde art group composed of young artists and intellectuals in various fields, which aimed to pursue cross-media art combining art, theater, film, fashion and music. Ten years later, he set off for Japan to experiment with print and video art, and in the 1980s traveled to the United States to pursue new ways of art practice.

After a long time, I have been seeing the price of hard disks is very strong, I saw Western Digital from Seagate, and then I saw Seagate from Western Digital. I took a look at JD.com, and finally the price of the hard drive has been reduced.DAHUA NVR4104-P-4KS2/L DAHUA NVR4108-4KS2/L DAHUA NVR4108HS-4KS2/L.

First look at Xiku!> The price of fish 2T is very good, but it is a pity that the house is smaller when I think of the young lady who is nearly 1T

Easy to Guard
Understandably, the basic development tendencies of AIoT brings better worry for community safety and the danger of sharing private details. But users really do not have to fear too much because by design and style NVR four. is effortless to guard.

Most smart cameras have a common problem of poor wireless signal reception. In my house at the gate, the mobile phone can be connected to wifi and can surf the Internet normally. However, many cameras do not do the same thing. It took a long time to find and change a lot of them, and then I got it~ The product is purchased by myself

In the rural areas of the north, basically every household has a large yard, but the yard is too large, and it is more troublesome to install surveillance. The wireless capabilities of ordinary cameras are not that strong at all. Before my house, I wanted to install surveillance at the gate, but I tried several cameras, and basically they could not connect to the Internet. Some of them can be connected, but the network is unstable, so this matter has been put up. However, a few days ago, when I saw that there was a UP sharing the villa’s no-dead monitoring solution, a camera with two pigtails was used at the door. I left a message and asked about the brand and effect. UP replied that it was Chuangmi Xiaobai. N4, the signal is not bad, so I also bought one, and took advantage of the weekend to go home and install it.
The installation process will be described in detail later. Let’s take a look at the product first. The brand is Chuangmi, the name is Xiaobai Smart Camera, and the model is the outdoor PTZ version N4. Everyone pay attention, as long as it is not used indoors, you must choose the outdoor version, because the outdoor version will be better in terms of waterproof, dustproof and stability. This one supports IP66 dustproof and waterproof, even if sd50225u-hni is exposed directly outside, it is not afraid of rain, snow and frost.
After unpacking, I found a lot of accessories inside, a pack of expansion screws, a sticker for positioning, a screwdriver, a power adapter with extra-long wires, and two paper documents. I kindly remind everyone here that the manual must be read, and don’t be blindly confident. I just didn’t read the manual during installation, and I made a small mistake in wiring.

This is another work worth thinking about. Takahiko Iimura’s representative work “This is the camera that took these pictures”

This video installation work is presented by two cameras and two surveillance screens in opposite directions, and the words from the title of the work are attached to the wall in the middle. In this work, originally exhibited at the American Center in Tokyo in 1980, Iimura created a loop that disrupted logic by changing the direction of the camera’s signal transmission so that each camera appeared to be filming itself.

How wonderful is this logic? In order to let everyone have a good experience, the artist put paper signs numbered 1 and 2 on the two cameras respectively.
Takahiko Iimura was born in Tokyo, Japan in 1937. He is a pioneering artist with a creative career spanning more than 50 years, DAHUA NVR4104-P-4KS2/L,DAHUA NVR4108-4KS2/L,DAHUA NVR4108HS-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4108-4KS2/L,DAHUA DH-NVR4108HS-4KS2/L,NVR4104-P-4KS2/L,NVR4108-4KS2/L,NVR4108HS-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4108-4KS2/L,DH-NVR4108HS-4KS2/L,NVR4104-P-4KS2/L Price,NVR4108-4KS2/L price,NVR4108HS-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4108-4KS2/L price,DH-NVR4108HS-4KS2/L price involving film, video, installation, performance and digital technology. Takahiko Iimura has worked in film since 1960 and has been instrumental in the burgeoning Japanese experimental and independent film scene. In 1966, he received a scholarship from Harvard University and moved to the United States, where he soon joined the experimental film and art community in New York in the mid-1960s. His early video works were included in exhibitions at the Museum of Modern Art and PS1 in New York, and at the Centre Pompidou in Paris, France, and his performance-based works and interactive installations were included in a two-person solo exhibition at the Whitney Museum of American Art in 1979. “New Video” on display.

This is the Xiaobai N4 camera. The two antennas on the fuselage are small pigtail antennas that can be rotated. The core parameters of the camera are very good, 3 million pixels, the focal length is 3.6mm, the aperture is F2.0, and the infrared night vision distance reaches 30. In this price range, the configuration is still relatively high.
The place on the back of the camera fixed with two screws is the REST hole and the TF card slot, which is designed to be dust-proof and waterproof. The pictures recorded by this camera can be saved to the cloud, or to the local TF card.DAHUA NVR4104-P-4KS2/L,DAHUA NVR4108-4KS2/L,DAHUA NVR4108HS-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4108-4KS2/L,DAHUA DH-NVR4108HS-4KS2/L,NVR4104-P-4KS2/L,NVR4108-4KS2/L,NVR4108HS-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4108-4KS2/L,DH-NVR4108HS-4KS2/L,NVR4104-P-4KS2/L Price,NVR4108-4KS2/L price,NVR4108HS-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4108-4KS2/L price,DH-NVR4108HS-4KS2/L price. You can also set it up in the system and save it to the NAS. The UP with the villa saves the surveillance video to the NAS.
Before installation, I tested whether the camera can be bound normally and the network speed of this location. The results made me very satisfied. The signal can reach 56%, which is very good. You know, I have tried several cameras before. , nvr5232-16p-4ks2e is basically impossible to connect normally. It seems that the two protruding pigtail antennas are really powerful.
First let my father hold the camera, set a general position, and mark the position with that paper. I am going to install it at the entrance of the south courtyard of my house, so that I can see the situation at the entrance of the north courtyard. (The landlord is from Shandong. Many rural families in my hometown have two yards. One is for living and living, and the other is for farming tools and livestock. My family also has two yards. My parents live in the north courtyard. The warehouse is used to store agricultural vehicles, and also has a dog, two geese, and a few chickens.)

Before installation, I bound and tested it on the Mijia of my mobile phone. After the installation, I shared the camera device to my parents’ Mijia account, so that my parents don’t have to do anything, just agree to my sharing and they will be available on It is very convenient to see the camera on the mobile phone. Now the rural home has achieved full coverage of the living room, patio and gate. Moreover, not only parents can check the monitoring with their mobile phones, but I can also check them at any time.
Well, the above is the process of installing a wireless camera in my hometown in the countryside. To summarize this Xiaobai N4, first of all, it can be connected to Mijia. For those who already have Mi-series products, there is no need for additional It can be used directly after installing the APP; secondly, its dustproof and waterproof ability is very strong, and it can be used directly outdoors without worrying about the wind and the sun; thirdly, ipc-ebw81242-as-s2 comes with dual antennas, and the wireless signal is very strong, which can reach the level of ordinary wireless cameras It is not connected to the distance, no additional wiring is required, and no relay is required, and it can be used directly after installation. In the past few days, I bought another small white N4, DAHUA NVR4104-P-4KS2/L,DAHUA NVR4108-4KS2/L,DAHUA NVR4108HS-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4108-4KS2/L,DAHUA DH-NVR4108HS-4KS2/L,NVR4104-P-4KS2/L,NVR4108-4KS2/L,NVR4108HS-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4108-4KS2/L,DH-NVR4108HS-4KS2/L,NVR4104-P-4KS2/L Price,NVR4108-4KS2/L price,NVR4108HS-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4108-4KS2/L price,DH-NVR4108HS-4KS2/L price and I plan to install it outside my window. I live on the 3rd floor and the garage is on the ground. If it is installed outside the window, the garage can be directly monitored. At present, whether it is a large yard in the countryside, a large yard in a villa, or a multi-layer user, if you want to use it outdoors, the Xiaobai N4 is still very good, dustproof and waterproof, the key is the external dual antenna, long distance It can also be used on the Internet normally, which is much stronger than the average camera!

Since I saw that the steps to install Hass.io are very simple, the purely graphical operation is suitable for a fool like me, until I entered the SSH interface. It’s completely different from the tutorial! I tried to enter the “sudo npm install -g homebridge-camera-ffmpeg” plugin installation instruction, no suspense does not work! After asking for help in many great groups of gods, they all said that they were powerless. It is strongly recommended to replace the Hassbian system with integrated Hass control. Now that there is nowhere to go, reload it.

Insert the TF card into the Raspberry Pi, connect the power supply and wait slowly. Judging from my previous experience, this period is enough to watch online dramas. If you are worried that the Raspberry DAHUA NVR4104-P-4KS2/L,DAHUA NVR4108-4KS2/L,DAHUA NVR4108HS-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4108-4KS2/L,DAHUA DH-NVR4108HS-4KS2/L,NVR4104-P-4KS2/L,NVR4108-4KS2/L,NVR4108HS-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4108-4KS2/L,DH-NVR4108HS-4KS2/L,NVR4104-P-4KS2/L Price,NVR4108-4KS2/L price,NVR4108HS-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4108-4KS2/L price,DH-NVR4108HS-4KS2/L price is not working, open the router’s management interface and check its network traffic. If there is a fluctuation, ipc-hdbw2531e-s-s2 means it is still working.
In the past, the home has been using Yingshi series monitoring, but the outdoor waterproof and zoom dome camera does not. In the end, I found that there are a lot of Hikvision brands, so I simply bought a 2dc7423iw with the largest zoom. Let’s take a look at the powerful zoom effect of the dome camera first. The focal length of the camera is 4.8mm. The first one is before zooming, and the second one is after 23x zoom. This is an optical zoom.
Let’s talk about the advantages of the ball machine first.

1. It can 360-degree cruise. Several fixed-angle monitors were originally installed, but now a ball machine can handle it. Two dome cameras in the front and back of the house can cover the whole, and at least 6 fixed-angle monitors are required.

2. Super zoom, easy to see all the details. And the recording process will automatically follow and zoom in. Since there is no way to transmit video, the tracking shooting of the dome camera is really amazing. If someone walks by, it will automatically focus on the person and keep shooting.

The disadvantage is that it is heavy and troublesome to install. The 5kg I bought is like a big dumbbell. There is no wifi model, you can only connect to the network cable.
This is the first time I bought a bracket, and I found it too short. It is recommended that you buy a bracket with a length of about 1 meter. You can extend it farther to cover more angles. The picture below shows the 1.2-meter bracket used.

1. Children such as Xiaodu at home have a little amblyopia in the left eye and do not want him to look at small screen devices.

2. Install WeChat on an idle mobile phone, in the same way 1, there is a risk of indulging in games. Every night, she can use her mother’s mobile phone to say good night and make a video.

3. Smart camera.

Because there are elderly people at home, there is no need for security, and individuals do not trust major Internet manufacturers. Traditional cameras have to be connected to video recorders, which is too much trouble. (In the past two years, I often saw the kind of video of the 360 ​​water drop camera, and I was a little afraid that I could connect to the Mijia Dahua Lecheng smart camera).

Choice of brands

Smart cameras from traditional manufacturers such as Haikang, Dahua and Qiao An

Mobile Internet manufacturers 360 Xiaomi, Huawei, etc.

I am a miboy (mainly a poor Dahua Lecheng smart camera that can be connected to Mijia). I have some Xiaomi devices at home. It is best to install one less app on my mobile phone. Then look for the camera that can be connected to Mijia. . .

The “Big Brother Is Watching You” plan failed.

After returning to the field, I looked through Xiaomi Youpin, and actually saw the EZVIZ camera inside (consulted customer service and said it was a customized version of EZVIZ tp2 Xiaomi). This is not a sub-brand of Huahua.

Look at the parameters again:

DAHUA NVR4104-P-4KS2/L,DAHUA NVR4108-4KS2/L,DAHUA NVR4108HS-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4108-4KS2/L,DAHUA DH-NVR4108HS-4KS2/L,NVR4104-P-4KS2/L,NVR4108-4KS2/L,NVR4108HS-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4108-4KS2/L,DH-NVR4108HS-4KS2/L,NVR4104-P-4KS2/L Price,NVR4108-4KS2/L price,NVR4108HS-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4108-4KS2/L price,DH-NVR4108HS-4KS2/L price 1080p with gimbal

Two-way voice (remote control plus brainwashing)

Access to Mijia Control (one less app installed)

In order to prevent accidental fall during installation, a wire rope can be used as a safety rope. The tf card can be installed in the ball machine. Due to the complicated installation, you must buy a good quality plug. So that the TF card is not damaged in the future, and it will crash when it is replaced.

The biggest difficulty in the installation should be that the network cable was not wired in advance. I didn’t expect this problem. In the end, I tried a lot of methods, but the power cat solved it. The Tenda gigabit power cat used, with 2 400w ball machines, is currently very stable. The power cat is best used downstairs on the same floor, so that the impact is minimal.
Colleagues in the catering business know the usefulness of the camera. Especially the webcam, with the APP, you can see the general situation of the customer flow in the store when you pick up the mobile phone, and the various benefits are not listed one by one.

The following two are the silver machines that the IQ camera should focus on. Come! Stare at my little restaurant! ——Foscom IQ smart camera restaurant application example

The store has now installed five Hikvision high-definition digital cameras, as well as two Kaicong brand network cameras, which are known as Ma Yun’s family’s No. 1 sales. I have installed seven, why do I still need it? Because of the key position of the cashier, the Kaicong webcam installed on the top of the cashier had deserted every three days, either unable to connect or unable to record video. Although there is a DAHUA NVR4104-P-4KS2/L,DAHUA NVR4108-4KS2/L,DAHUA NVR4108HS-4KS2/L,DAHUA DH-NVR4104-P-4KS2/L,DAHUA DH-NVR4108-4KS2/L,DAHUA DH-NVR4108HS-4KS2/L,NVR4104-P-4KS2/L,NVR4108-4KS2/L,NVR4108HS-4KS2/L,DH-NVR4104-P-4KS2/L,DH-NVR4108-4KS2/L,DH-NVR4108HS-4KS2/L,NVR4104-P-4KS2/L Price,NVR4108-4KS2/L price,NVR4108HS-4KS2/L price,DH-NVR4104-P-4KS2/L price,DH-NVR4108-4KS2/L price,DH-NVR4108HS-4KS2/L price rotation function, it is basically useless. It took a while to realize that at the cashier counter, all you need is to stare at it all day, and you can still see an M when you rotate it to other angles.

Haikang’s two bolts and three hemispheres are all 100W, and the effect is very good, but the disadvantage is that it is not cheap (I borrowed a 1.3 million pixel picture on the Internet, but the appearance is the same);

Come! Stare at my little restaurant! ——Foscom IQ ipc-hdw2439t-as-led-s2 Camera restaurant application example

The Kaicong webcams of “Ma Yun’s first-selling family”, these two are equipped with rotation, with voice monitoring and call functions… Anyway, the business is whirling around. The disadvantage is that the definition is not good, it is called 720P… It is not compatible with the Haikang software, and occasionally the wind is not strong, and the image cannot be seen in the software (this is the most unbearable)! Come! Stare at my little restaurant! ——Foscom IQ smart camera restaurant application example

To bring comprehensive defense to the method, the freshly added stability protocol supports Firewall for Community Safety Specifications, Access Restriction (MAC handle binding) as properly as 802.1x Obtain Authentication.

It is also value noting that Seagate* SHM(Self Wellness Management), many thanks to the embedded software for avoidance, intervention and recovery, can actively safeguard the info protection.
