In a weeks time the IPC-Color4K-T180 has had no signal 1750 times. This has been happening for the longest time. What is the problem. I have run brand new wire, I have tried multiple switches, I have tried just a stand alone injector. I don't know what else to do. What is wrong with the damn camera?? Do I need to talk to Andy? Has anyone else experienced this? If so, did you see the same problem? Were you able to fix it?
