Talking about the Monitoring and Installation of Elevator

In one case, the video cable is reserved in the elevator accompanying cable, and you only need to pull the cable from the elevator machine room to the monitoring room on the third floor, about 24 meters.

In addition, if there is no reserved video line in the accompanying cable of the elevator, there are two situations. First, if the accompanying cable is fixed in half of the elevator shaft, you only need to lay a video cable along the accompanying cable of the elevator, which is about 18m, come out from the place where the accompanying cable is fixed, between the fifth floor and the sixth floor, and then pull it from here to the third floor, which adds up to about 27m. Two: If the accompanying cable is fixed in the elevator room, you need to lay a video cable along the accompanying cable, about 33 meters, and then pull it from the elevator room to the monitoring room, about 24 meters, that is, 57 meters.

The power supply can be directly connected from the elevator car, generally connected to the elevator lighting circuit, and other circuits will interfere, so it is recommended not to connect. But this has a disadvantage. When the elevator is being maintained or repaired, the lighting circuit is sometimes turned off, resulting in no video output. But the impact is not big, most of them do this.

If there is video interference, it is recommended to add a power amplifier to the computer room. Choose elevator power carefully. It is best to pull a separate cable from the computer room. Generally, there are reserved cables in the accompanying cables. You can use two.
