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 fed through travellers. The elevator company should make provisions for you to run wires through their travellers or you can install a new traveller. However, installing a new traveller is an expensive option.

Elevator cable travel design & CCTV camera

In a conventional elevator all signals and currents are sent through a travel cable. Elevator cable is a special multi conductor cable continuously in motion, and usually has a long lifespan. There are two basic types of cables, they are round and flat. A round cable can contain as much as 120 conductors and offers greater flexibility.

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 telecommunications and coaxial cable for close-circuit television.

Using a laser signal for a wireless transmitter and receiver is high in demand. The laser optic transmitter will be mounted to the underside of the elevator cab, with the CCTV camera mounted to the ceiling of the elevator cab and wired via a coax cable. The wireless receiver will be mounted on the elevator shaft floor, aligned and pointed upwards to the transmitter. The receiver is connected with DVR via coax. The laser wireless receiver and transmitter can work up to 1,300ft, transmitter and receiver should be configured with same settings.
