Hi - Has anyone ever experienced this one?
I have a client who's Surveillance System video footage have scrolling lines only at night. - And some of the cameras... the images go in and out (disappear) only at night too. Then come sunrise the problems go away. - The system worked perfectly for several months.
I've tried the following:
+ Set-up the DVR at our office ran it for two days - No issues
+ Unplugged every camera one at a time at clients location - Same issue (was trying to rule out one of the cameras)
+ It seems as if there is some kind of interference but nothings changed and it's only at NIGHT.
After almost 5 years in this business this is a first
Thanks
