Hum bars in video but only on a cold day

Issue

Video shows hum bars but only on a cold day

Product Line

Pelco Cameras

Environment

  • EH2512-2
  • GIT100

Cause

When the heaters turn on in the enclosure the power draw on the power wire for the EH2512-2 will go up and you get a larger RF signal and this will give you hum bars in the video.

Resolution

Isolate power away from the coax or install a GIT100
