Duplicated ip

[Kashii]

Soooo longstory short
I installed a set of 18 lorex cameras system with a nvr for a client after the installation i was just doing the final setup, making sure everything was working fine
Etc, but while doing it, 2 out of the 18 cameras where showing the same image as other 2 cameras, so i checked the device list on the nvr, turns out the cameras that were duplicated had duplicated ips too... i tried changing the ip but then the camera doesnt even work at all

I don't have a NVR, as I use Blue Iris (VMS on a PC) and so was waiting for someone with more NVR experience to chime in.
Until then, I'd suggest you perform a hard reset on one of the cams while plugged into the NVR.
The intent is for the cam to default to DHCP and receive an IP again from the NVR.
If no joy, try this on the other cam that has the same IP.
