Our recently installed day/night Laice security cameras have gone out (black) one by one.?

Question

We now have no picture at all, day or night - any suggestions as to the problem? We've checked the wiring and connections - all OK. This has happened gradually, one camera going at a time. (The system is only three months old).

Answer 1

maybe somebody is messing with them, maybe they covered the camera lense with something, just to be idiots!

Answer 2

Then check the manual troubleshoot, or see if there is a recall or get a refund.

If this is a company that is doing the security then as for a technician.
