I have a Swann NVR8-7082 with all 8 NHD 806 cameras, build number 1025 GA 2.1 and I have had this system since 2015.
My display screen is now showing all cameras as Video Loss.
I have carried out reboots, the usual unplugging EVERYTHING and it does not rectify my issue.
What I have noticed is that when I connect the system to the wall power socket, all the lights at the 8 ports for the camera inputs at the back of the NVR box flash for a second and then go out.
Normally the lights are usually all on at the ports on the back.
I have a steady Green, Red and Blue light on the front of the NVR box. So power is getting to the box and my connected screens, but no power to any cameras and the infra red lights on each camera are not lit either.
The only thing I have not yet done is a complete system restore.
I have logged a case with Swann, but being the holiday period, I expect no help for a while.
Has anyone any suggestions please ?
