Dear All,

I recently updated NVR model DS-7716/32NI-E4(-E4/16P) to firmware version V3.4.92_170228 and since then when i connect camera model
DS-2CD2012F-I(W)(firmware 5.4.5_170123) directly to NVR. The Camera does not power up.( ports remains shutdown).

i have tried to power camera using DC adaptor and it works fine, i can access the camera and view image.

Issue seems to be with NVR poe.

Can Any please help

Leeroy,
Do you have any other cameras on your system and are they receiving power from the ports on your NVR?
Have you tried the DS-2CD2012F-I(W) camera on any other ports of your NVR?
What lights come on at the port when you plug the camera in?
If you only have the one camera to test with, have you tried another lead?
I assume you are connecting the camera direct (ie; one short lead) to the NVR.
