Maximum Cable Lengths

IA76
in CCTV & Access Control

Hello

What are the maximum cable lengths for video & 12v power cable to a cctv camera with infrared?

TIA

Depends on the current draw and the thickness of cable.

The opinions I express are mine and are usually correct!

(Except when I'm wrong)(which I'm not)

Hi there

What type of camera are we talking about here?

Because the draw off the Ir unit can be anything from 1-500w

Regards

Alex

12V IR's even if LED can pull some serious current so cable lengths should usually be as short as possible and in flex rather that alarm cable.

We usually get a mains cable dragged out to the camera to save the day...

The specs for the camera show:-

Operating Voltage: 12V DC 750mA

What about video cable? What is the max length for that?

750ma on alarm cable (single cores)= approx 16 metres

750ma on 1mm T&E= approx 70 metres

Basically the thicker the cable the less voltage drop.

IIRC RG59 video cable is good for approx 250/300 metres, if you use CAT5 and baluns you can go approx 500m with passive baluns and 1km with active baluns.
