How do I fix horizontal lines on my CCTV camera?
Try a different camera SOLUTION: If the problem continues or is not resolved, then you can also try a camera with WDR or Widen Dynamic Range such as an Effio Series DSP camera. You can also try a CMOS sensor camera because such a device does not face the problem of horizontal lines.
How do I remove interference from CCTV?
As with flickering, you should check and eliminate typical sources of interference: Check connectors and cables for damage, especially analogue video cables. Make sure all cables are routed correctly, away from interference sources, and correctly grounded if required.
How do I stop CCTV ghosting?

How do you test a ground loop?
To test for ground loop:
- Set your volt meter to the most sensitive AC setting.
- Disconnect the camera you want to test.
- Place one contact on any exposed metal of the chassis.
- Place the other contact on the outside of the connector on the coax from the camera.
- Any value above 0 indicates a ground loop.
How do I get rid of a horizontal line in a video?

What is CCTV ghosting?
Ghost on CCTV cameras can also be caused by slow shutter speed, high gain, high DNR, high DWDR and smoothing settings. Taking the noise reduction for example, the higher the noise reduction is, the worse the CCTV camera ghosting effect becomes.
How many days CCTV footage is kept?
