4.5 Cable Runs
The maximum achievable cable run is limited by the voltage drop in the chosen cable and also the
quality of the video cable which can cause signal loss and interference.
Resistance differs depending on the cable used and the higher the resistance the more the voltage
drops hence the shorter cable run achievable.
It is recommended to use one of three types of cable, PTZ combo cable sometimes known as
RG59+4, CAT5+2 cable or 4 core cable with 0.3mm2 cores.
Below shows the maximum recommended cable run for each cable type. Cable runs exceeding
the stated maximum run are at risk of issues caused by voltage drop and non performance of
equipment.
