How to connect eight lines of building video intercom telephone

Generally, there are four pairs of cables, orange white, orange, green white, green, blue white, blue, brown white and brown. When installing, RJ45 crystal heads on both sides have been completed, and the line sequence at both ends is corresponding. If the wire is broken, first check whether there is any connected wire at the broken place, and separate it first to prevent the power cord from touching other extension wires or connecting equipment between floors.

Thirdly, if you want to connect, "Note" that it is best to find the property or relevant personnel to unplug the wires in your home at the floor connection equipment and connect them with corresponding colors, preferably by welding with ferrochrome (so as not to be afraid of wire oxidation at the interface).

Because the wire is buried in the wall, if it is oxidized, it is not good to smash the wall. Wrap it with electrical tape or heat shrinkable tube, and then insert the corresponding opening at the joint of the floor. If you are not sure, it is best to find the manufacturer's technicians or related weak current engineering technicians to deal with it.

Introduction:

The walkie-talkie covers a wide range. Here, we call all radio communication equipment working in ultrashort wave frequency band (VHF 30 ~ 300 MHz, UHF 300 ~ 300mhz) radio interphone, in fact, it should be called ultrashort wave FM radiotelephone according to relevant national standards.

People usually refer to hand-held wireless phones with low power and volume as "walkie-talkies", and some people are used to calling them "walkie-talkies" and "walkie-talkies". A high-power and high-volume wireless telephone that can be installed on a vehicle (ship) or used fixedly is called a "radio station", such as a vehicle-mounted radio station, an ocean radio station, a fixed radio station, a base station and a turntable.
