Product Line

Pelco Cameras, Pelco Transmission & Power

Environment

  • Cameras (analog)
  • Power Supply
  • Wire Awg type

Cause

Camera is not powering up over a given power wire awg and a given distance.

Example if you have a Spectra camera that uses 73VA from a power supply, the wire is 80 feet from camera to power supply.  You would have to use a minimum 16 Gauge wire for power.

Same Example as above but distance changes from 80 feet to 150 feet from the camera.  You would have to use a minimum 14 Gauge wire.

 

NOTE: MAX SIZE IS 14 GAUGE WIRE THAT WILL FIT IN TERMINAL BLOCK FOR POWER.
