Hi StuartM. Yes, we thought of interposing a POE switch between the NVR and the cameras to just prove a point (if it was no POE that was the problem the cameras should work) but neither of us has the necessary switch and we weren't going to buy one just for this. We are now thinking what to do...
Thanks for all the help and advice. This NVR actually belonged to my brother and he has decided to return the NVR to his supplier. We tried all three cameras, plus a new one out-of-the-box and none will work with this NVR on a 2-metre pre-made network cable. Seems that there is an NVR fault. We...

No further POE errors since I did the "restore". The CAT5E cables...
Hi StuartM,

Intermittently the NVR will drop one or more of the cameras and a reboot and a power off/on will not always get the cameras back on line. What I...
