IPC-HFW4231E-SE Stopped Working

[ooom416354]

Hi, I have had a camera set up on the side of my house for a few months now. Camera is IPC-HFW4231E-SE with the DVR being NVR5208-8P-4KS2. It has always worked, but the past week or so it just stopped out of nowhere. I still see it is on and getting power when going to the actual camera; night vision lights are on, etc. but it does not show up anymore in the DVR. Is there anything I could do to troubleshoot this without taking the entire camera off the house?

Thanks!
