I am getting horizontal interference lines running through my picture on some cameras in corridors where they are installing new bright led lighting above my cameras. I was thinking electrical interference but my wires are not near the electrical wires. Electrician is running his lights and conduit surface mount on ceiling. Is it possible it’s a led frequency thing?

I’m not an camera expert, but I do know light. Flickering light is a pain for camera and humans. Can be measured by using this free app. When I buy LED for my home, I always try to get as low as possible. Best is less then 5% (flicker free).

More likely to be flickering light than EM interference, though LED bulbs can also be electrically noisy.

please provide a video of the problem.

I agree it may be the flicker of the lights beating against each other. There have been a number of post about lights on different electric phase, on different circuits, causing lines to move up or down the video.

on some cameras there is an Anti-flicker option on exposure settings.

What make and model cameras

I bet it’s Flicker then. I will take a video tomorrow. Pictures didn’t seem to capture it. They are uniview 5mp turret cameras. Will check tomorrow if they have the anti flicker option. Thanks a bunch for help guys.

A snap shot picture sill not show the problem. Record ~30 second video. Post it to youtube, then link it into the post

That is the lights.
Good video.

Look for setting in the camera to reduce the flicker.
Make sure the camera and all lights are on the same electric phase,this will reduce the problem but may not prevent it.

I have mostly seen this a night with street lights and other light sources.

Late to the thread but I can verify I have had same issue. I have bought LED lights to use at night, and found that one of the floodlights I bought caused unpleasant flickering on a Hikvision PTZ camera. I assumed it must be a frequency thing too and sent it back to Amazon. Found another alternative which was fine and didn’t cause any problems...

Hi! How was your problem solved as a result? I had something similar with cameras in the office, and we couldn't figure out the problem. However, after replacing all the light bulbs in the room with smart lamps, the situation resolved itself. We ordered smart light bulbs at Vont Smart Bulb Color - Vont if suddenly it will be even more useful to you. I can't explain why the cameras reacted so much to ordinary light bulbs, but after replacing all the bulbs with LEDs, the problem disappeared.
