Hi everyone! First time poster, glad to meet you and hope you can help.
I've got my Hikvision 7216HUHI-F2 connected to several static cameras, in AHD, without issue. Indoor and outdoor, all work great with baluns over Cat6.
About 2 years ago, I ordered 3 new PTZ dome cameras from eBay. Never got around to installing until today. They don't seem to be giving me any picture. I've checked:
Baluns (tried several new ones
Cabling
Power (12v 2a .. and tried different power source)
Tried on a different DVR (Hikvision HUHI7216-K2)
... nothing. Just can't get any video output from any of the 3 PTZ cameras. Any suggestions?
