How to install CCTV cameras inan elevator?Installing CCTV cameras in an elevator can be a time consuming and complicated task. As elevators are moving objects, running wires can be a real challenge. Elevators normally use travellers to run wires and

any new wires can be f ed through travellers. The elevator company should make provisions for you to r un wires through their travellers or you can install a new tr aveller. However, installing a new traveller i s an

expensive option.

Elevator cable travel design & CCTVcameraIn a conventional elevator all signals and currents are sent through a tr avel cable. Elevator cable is a special multi conductor cable continuously in motion, and usually has a long lif espan. There are two basic

types of cables, they are r ound and flat. A round cable can contain as much as 120 conductors and offers greater f lexibility.

Let’s look at an old cable which contains 20-30 different size conductors, 14AWG (1.5mm2) for constant current for circuits, 18AWG (0.75mm2) for signals and 20AWG (0.5mm2) for t elecommunications and

coaxial cable for close-circuit television.

20AWG (0.5mm2) can be used for CCTV cameras and as many cameras require 12V power, this can be provided locally with the correct AMP.

The other option is to install a wireless transmitter and receiver, t here are many wireless transmitters and receivers on the market, but you should make sure you select a reliable one. Cheap transmitters often

cause interference and video will freeze at motion. You must also make sure you di splay a CCTV sign in the elevator for the data privacy act.
