Hello, do you need a network cable to install the monitoring head?

Analog surveillance camera using coaxial cable or network cable plus double hinged wire transmitter, network camera with network cable, now many indoor network cameras are equipped with wifi module, you can do not need to connect the network cable, directly connected to wifi.

The equipment used in network monitoring includes network cameras, network servers, etc., and you should be talking about network servers. Under normal circumstances, 75 ohm coaxial cable is used for transmission between the server and the camera, but due to the long transmission distance and the high cost of using coaxial cable transmission, network cable is used for transmission. However, due to the use of network cables to transmit the network cable itself and the transmission distance, due to the large attenuation, a twisted pair transmitter is used.

The computer connection is connected with the network cable and the network card of the device, if you want to use the same network cable, the network transmission uses 4, and the remaining 4 can be connected to 2 cameras.

For the monitoring installation of whether to use network cables, it should be determined from the purpose of monitoring and the surrounding environment of installation!

1.Small home monitoring: generally using wireless connection, the biggest advantage is that the installation and commissioning is simple, can avoid cumbersome construction wiring, and is very beautiful!

The premise of this method is that the WiFi signal strength in the LAN of the installation area must be good. The disadvantage of this method is that the stability is not good, and it is easy to drop the picture, freeze, delay and instability, which increases the maintenance cost in the later stage.

2.Large-scale factory or school monitoring: generally use wired connections, and this connection is not only network cables, because the transmission distance of network cables is generally about 100 meters, more than 100 meters will appear signal attenuation and distortion, resulting in signal and instability, at this time will use optical fiber transmission and bridges.

Transmission, over long distances using fiber optics, through fiber optic transceivers.

The optical signal is converted into a network signal, and the network cable is used in close proximity, and the switch is used to connect to the camera! The biggest advantage of this method is that the monitoring picture is stable, the clarity is higher, it is convenient to manage in batches, and the later maintenance is less, and the disadvantage is that the construction cloth is more difficult, and the early construction period is longer.

3.Ultra-long-distance monitoring: this kind of monitoring generally adopts GPRS traffic transmission, this method can be used for ultra-long-distance transmission and construction wiring is very difficult place, generally in some high-speed intersections to temporarily use the camera can be used in this way, the installation is simple and the signal is stable, and the later maintenance and debugging is also very easy.

You don't need a network cable to install monitoring, but if you want to see some monitoring content on your phone, you need to install a network cable.

To install the monitoring head, use a monitoring cable.

Now monitoring can also have wireless monitoring and mobile phone connection.

Now there are some surveillance cameras that don't need network cables. It's called wireless surveillance.

If you simply install a camera, you can also use a network cable.

If you want to install monitoring, you need to pull a network cable, or you can connect through a wireless network.

If it's the kind of wired surveillance camera, it does require a network cable, unless it's a wireless camera.

The network cable used by the security camera is generally the same as the home network cable.

1. The general network cable material is the same, and the general surveillance camera uses 8-core twisted pair cable, so this network cable can also be used on the computer at home.

2. The connection method of the crystal head is the same, and the general monitoring camera wiring is T568B, and the order is: orange-white, orange-white, green-white, blue-white, blue-white, green, brown-white, brown-white. This wiring method is a 100-megabit line sequence used by home computers.

3. Some monitoring network cables use a power cable, so the discarded power cable can also be used as an ordinary network cable at home.

4. If the camera is a coaxial cable, this cable cannot be called a network cable. This type of computer cannot be used in the home.

The camera with a network cable is PoE powered, and it needs to be connected to a POE recorder or switch. The network cable of the camera both supplies power and transmits data.

The installation of surveillance cameras at home only requires a wireless network environment, and does not require a network cable. After the installation of the home surveillance camera, according to the operation method of the manual, you can directly connect to the wireless network at home and start using it.

How to use the webcam:

Take the Mi Home camera as an example, open the Mi Home version, log in, click the + in the upper right corner of the home page, click the camera, select the device model, and operate according to the prompts on the page.

Precautions for the use of the camera chain:

1. When installing the camera, pay attention to the shooting angle, and do not have obstacles nearby.

2. The IP camera cannot work, it may be caused by network abnormality, you can restart the router or reset the router.

3. The general camera has a variety of ways to install the shed, which can be installed as needed, such as on the desktop and wall. <>

Some need it, some don't.

To install monitoring, it is not necessary to install a broadband network, but if there is no network, you can only do video storage, and you can't remotely view and real-time alarms, and the practicability of monitoring will be reduced a lot.

Additional questions about using monitoring:

1. In addition to video recording, surveillance cameras also have functions such as remote viewing, humanoid detection, real-time alarm, two-way voice call, etc., which need to rely on the network to achieve, if there is no network, the practicality of surveillance cameras will be greatly reduced.

2. Now there are some monitoring that supports 4G network cards, inserting 4G network cards can be directly connected to the Internet, and there is no need for broadband networks, but the use of 4G network cards also requires continuous traffic costs.

3. How big a memory card is needed for monitoring, which is related to the resolution of the camera, the coding format and the bit rate setting, and whether the dynamic inspection video is set for monitoring is also related. For example, a mainstream 2 million pixel camera, if you set up real-time recording, will occupy about 20G space per day, and a 64G memory card can store it for about 3 days. <>
