I recently installed 14 GW78 POE cameras. 4 cameras are connected directly to the NVR and never drop connection. I have 10 more cameras in an adjoining location. The cameras are connected to a POE switch which is connected via Ethernet to the same router as the NVR. These 10 cameras will work for a few hours and then randomly start dropping connection. I should be seeing 14 cameras at all times, but most of the time I am limited to 8 or nine. Help!

First, check for firmware upgrade for NVR.
Check your NVR settings under network/switch and take note of the IP subnet your NVR is using to assign IPs to cameras.
Then use a laptop or desktop computer to manually log in to each of the cameras that are not directly connected to nvr. In camera settings set the network IP to static and set each camera to a different IP using same subnet as NVR and make sure IP isn’t already used by one of the cameras plugged in to NVR. use the NVR switch IP as the default gateway and DNS.
Let me know if this helps.
Advanced IP scanner program makes it a lot easier to work with the cameras on network. It will scan and list all connected cameras and allow you to get to login screen by double clicking the link under the drop down for each device. May have to install a plugin for browser to be able to log in to camera directly, but it prompt you to do so if needed.

The problem is solved. The 10 external cameras were receiving IP's from the DHCP router. It was not configured correctly, so the cameras for some reason were changing IP's. I assigned static IP's to all the cameras connected via the POE switch, and that fixed the problem.
Thank you for your suggestions - got me thinking differently.

Awesome. I think it has something to do with the dhcp and lease time of the router. The same thing also occurs a lot with SONOS audio systems. You’d be surprised how many issues assigning static IP can fix.

Hi Third Coast I am having a similar issue. Can you tell me where to get that advanced IP scanner? is it just an IP scanner like Angry IP scanner? and how do I log in to individual cameras?

sorry that was silly. The program is actually called Advanced IP Scanner. Got it.

So where do you get the password to these cameras? like what would be the default?
