the ip address is not showing in the device list so i cannot access/edit the cameras in the list that are all offline .

all cameras are saying 'failed to find network host'
 
We need quite a few more details to be able to make suggestions that could help.

Is this an installation that used to work and you've changed something?
Is it a new one you're trying to set up?
What model and brand of NVR and cameras?
How is everything connected?
Have the cameras between connected and configured separately for testing purposes?
And anything else that might help to understand the problem you'd like help with.
 
yes the installation worked up until two weeks ago, it is not a new one.
the cameras are ony-x and the nvr is cognitio
the cameras are hard wired to the nvr
all ports are connected well, the wifi is defo working, we have tried turning the power to the whole building off as i read it could be that simple, it was not.

i have seen how to reset the cameras via deleting and reinstalling but i am unable to do that as the ip address is not in the top box
 
Just chiming in is the cameras set to static IP addresses? If power failed and rebooted everything maybe the IP address has changed. I use Advanced IP Scanner to see what all is on the network. Best to always jot down the MAC address so it is easier to locate on the IP Scan
 
I missed where you said the cameras are wired to the NVR. In network settings try changing it to DHCP if the IP is Static IP and see if the cameras come up. That would be the easiest thing to try. The NVR has it's own POE output and usually that don't go bad. If your NVR does get a IP address under DHCP then you can make the DHCP address static after that. If the cameras still don't show up then try a external POE switch in case the NVR POE failed
