Hello!
I had a mix of 1MP bullet and dome IP cameras, for a total of 8. I just added 2 more 1MP bullet IP cameras, model IPOB-EL1MPIR50-E for a total of 10. I logged in to the web interface of the cameras and set the IP to static on each of them and used 10.1.1.99 for one and 10.1.1.100 for the other. After about one night of operation, both cameras continuously end up with an IP of 10.1.1.80 for no apparent reason. When I log back in to them, the video actually switches randomly between the two because they are both on the same IP. I have had to change them back 3 times now in just 2 days. They are not being completely reset to default, as my admin password still works.
It should be noted that these cameras are both plugged in to the switch (IP 10.1.1.1) on the back of our NVR. The NVR is model NVR-ELE32C-16P4K, 32 channel 4K NVR with 16 PoE ports.
Any help or ideas would be greatly appreciated!
