The distance the power can travel depends on the thickness (Gauge AWG) of the cable and the amount of power being drawn.

Typically a fixed lens 12 volt CCTV camera will draw less than 500ma of power and as a guide a Cat 5e cable is 24AWG and a Cat 6 cable is 23AWG. If your power cable is a multi-core like Cat 5e or alarm cable you can use more than one core to extend the distance.

The following tables provide approximate distances that can be used a a guide
