Analog camera lines at night

[obcmookie]

Any body be able to help whats going on with this camera, its one of those basic lorex analog 2mp cameras. Was install around November of 2024, other cameras installed during that time are fine.

During the day , they are fine
At night, lines all over

Hard to say. Have they always been like that?
Installed with RG59, or Cat5 and video baluns?

Likely interference from Power, or corroded connectors, I'd start there

 

[obcmookie]

Sorry, should have included that bit. No, its been fine till recently. I'll check for corrosion.

Yes, cat5 and video baluns

Baluns go bad, connections get corroded.

Its been a couple years but I used to have a number of HDCVI systems. Power supplies were always a thorn in my side.\
But honestly those look more like connection issues to me

Ground loop and or power supply starting to fail? Could be as stated before connection and even issue with connection inside DVR, like one camera connection being pulled and causing damage in DVR. What happens if you move cables? Someone move power supply line or route power cables around dvr connection or cables?

 

[bigredfish]

Yep, Any number of things. Moving to a different BNC channel couldnt hurt, still could be power supply issue.

I seen this before when more than 2 wires/pairs have been used with the baluns. Causing crosstalk.
