How to connect the video intercom extension cable to the crystal head

After peeling off the skin, you will see the lines. The network cable is 8 cores. You can observe that the colors of the eight lines are different. Here is the most critical step, the order. There is a formula for arranging lines from left to right: white orange, orange, white green, blue, white blue, green, white brown and brown.

Hold the neatly cut network cable and plug it into the crystal head. When inserting, the order must not be out of order, and the network cable must be pushed to the end.

Intercom has developed rapidly. At present, it is all network cable connection. Just plug the crystal head into RJ45 interface, which is very simple and convenient. If it is some old-fashioned intercom products, there are generally two power lines, one ground wire, one B+, two signal lines, one audio (A) and one video (V). Just follow the logo connection.
