The 8-core CF851 network integrated cable is used for video surveillance, and its name is: network monitoring cable, monitoring integrated cable, network monitoring integrated cable. It has both power supply and network cable, and is composed of 8-core oxygen free copper Category 5e network cable and 2 0.5 power cables. The general transmission distance is over 200. The principle of use is:

If the distance exceeds 10 meters, it is generally recommended to connect the power cord in the integrated line to 220V and extend it to the position where the camera is installed before installing the power supply. Otherwise, the power supply will be insufficient. Of course, you can also use a screwdriver to adjust the voltage of the centralized power supply. There is a yellow resistor for adjusting the voltage at the centralized power supply. After connecting the wires, use a meter to test the voltage at the camera end to see if it is sufficient for 12V. Generally, it is better to adjust it to between 12.1-3V, not too large or too small, which is better. In addition, the power cord core of the integrated cable is relatively small, usually around 0.3, and it is not recommended to extend it too long. It is also unknown whether it is pure copper, as there is a certain resistance present.
