That does not evidence good connections...by far the most common reason for these failures is related to bad crimps, using cheap CCA cables, or failure to use the 568 standard when wiring...
if they all go out at once and they are all directly connected to the nvr..then you have a hardware or firmware defect in the nvr.
You have to wait until someone who has experience with these NVR's to chime in...you can easily brick it if you update incorrect firmware.
IP cameras a FAR superior than "coaxial DVR's"...You think DVRs have no issues? They have just as many problems if not more.
Actually my cameras were bought from a dealer in China that deals with hikvision primarilly. Also i have a dvr that's for years running with no issues at all. Atleast thats my experience. And the dvr was a no name brand. When buying these hikvisions my research showed no differance between Chinese and Usa dealers apart from price. Even the cams bought in USA Europe etc are imported from same dealers in China. Correct me if I'm wrong. I still feel it isn't a hardware fault but who knows.
Lol, you were SCAMMED by a china seller. There is a difference between the china and world region products..build wise as well as FIRMWARE...that is where you were lied to and went wrong.
Buildwise ? Are you talking about hardware or firmware build versions? Also firmware I know is differant as it is a chinese multi lingual hack... yet if hardware is same their should work just fine.
