Using the Video Interference Filter

Some dual-voltage Hikvision cameras are susceptible to video signal

interference due to AC current spikes. These spikes are not drastic

enough to affect functionality, but can create interference in the

output video signal in the form of moving horizontal lines. Some DC

powered cameras are also affected by current entering the camera.

The current can pick up a high frequency oscillating signal from the

surroundings and carry it into the camera, causing interference.

To remedy this, Hikvision began including the following items with

select cameras since June 2019:

• Select Dual-Voltage Cameras: 24 VAC to 12 VDC power

converter/filter

• Select DC-Only Cameras: High frequency power filter (does not

convert power, which is unneeded by DC-only cameras)

Cameras that may require these filters are listed at the end of this

section.
