The line sequence arrangement of network cameras usually follows the standard Ethernet line sequence, namely T568B standard. The standard line sequence arrangement is as follows:
1. Orange white (or white orange)
2. Orange
3. Green white (or white green)
4. Blue
5. Blue white (or white blue)
6. Green
7. Brown white (or white brown)
8. Brown
In practical applications, network cameras are usually connected to Ethernet cables using RJ-45 connectors (i.e. crystal heads). The wire sequence arrangement of the joint needs to be consistent with the above standards to ensure the stability and reliability of data transmission.
For network cameras, in addition to network cable connections, the following points should also be noted:
1. Power connection: Network cameras usually require an external power supply, so it is important to ensure that the power connection is correct and that the voltage, current, and other parameters meet the requirements of the camera.
2. Data transmission: Ethernet cables are not only used for power supply, but also for transmitting video data captured by cameras. The quality of network cables can also affect the quality and stability of video transmission.
3. Environmental adaptability: Network cameras are usually installed in different outdoor or indoor environments, so they need to have certain environmental adaptability, such as waterproof, dustproof, anti-corrosion, etc.
When connecting a network camera, the following points should also be noted:
1. The production of crystal heads: When making crystal heads, it is necessary to ensure that the wire sequence is arranged correctly, and use tools such as wire pliers to press the crystal heads tightly to avoid loosening or falling off.
2. Network cable length: The length of the network cable can affect the quality and stability of data transmission. Generally speaking, the length of the network cable should not be too long, otherwise it may cause signal attenuation or loss.
3. Testing and Debugging: After the connection is completed, testing and debugging are required to ensure that the camera can work properly and transmit clear video images.
The line sequence arrangement of network cameras follows the T568B standard, and attention should be paid to issues such as power connection, data transmission, environmental adaptability, and crystal head production.
