Power protection causing loss of recording

Hello,

I have a 4 channel Dahua NVR (DHI-NVR4104HS-P-AI/ANZ) with 4 cameras (IPC-HDW3866EMP)

During the night when the IR kicks in the 4th camera stops recording intermittently. The picture shows the error message.

Is this a fault with the NVR or have I got the settings too high for the NVR to cope with?

Thanks

Seems might want to look at using one of the cameras on an external POE switch it would seem. Your NVR has a total 36w I think and to be honest that isn't much to power devices. Or could change one of the cameras to work in B/W without IR on or Color mode at night. If not enough light for B./W without IR, or to run in Color at night then POE switch or Injector would be next thing.

Fault of NVR or camera well it is lower power output NVR or high power cameras either way could be an issue with a camera that is trying to take to much power as I don't know the camera..
 
So looking up the camera, IT does say that running 4 of them would be right at your NVRs max POE.. Give or take a little head room.. Says 4 cameras would be 35.6w with IR, and Ai enabled.. So I guess your NVR little shy on the output with no + for output current offered..

Thanks for your response mate.

I think you’re right, the POE injector may be the way forward but I’ll try play around with the settings first to see if I can get it below 36W. When it does stop recording it only just exceeds it but I guess that’s enough

Sounds like the NVR is working how it should but not powerful enough for my setup. I know it’s not a camera fault because I can replicate the issue on each camera in port 4.

Thanks again!
