I have a 8 channel NVR fully populated (5 IP Network Indoor/Outdoor IR Bullet Security Camera and 3 2 Megapixel ONVIF TP Series IP Long Range IR Bullet Camera) with an external POE switch. Here is a brief summary of my problem:

- Every other day  2 to 4 of my bullet cameras go offline ( marked with x). I have no problem with ONVIF cameras.

- When I do a Device Search, I notice the offline cameras show up on the list with new IP addresses

- Since all 8 channels are used, I have to delete the offline ones and add the same cameras with new ip address

Question for experts here:

1) Any idea why the cameras are going offline so often

2) is there a way to set static ip address for these type of cameras?

3) Am I overloading the NVR or POE by using all 8 channels?

Thanks in advance,
