Cameras IP changing after power outage…

[LeeBow]

Hi all,

I’ve got a 16 port poe HiLook NVR.

8 cameras directly connected to the POE on the NVR

4 cameras connected to a POE switch - which then plugs into the 9th network port on the NVR.

Everything was working great - had a power outage, now the cameras on the POE switch will not work.

In SADP, they show up, then after a random few seconds, the IP addresses keep changing.

192.168.254.168, then after say 10sec, move to .120

I’ve tried to set them to DHCP, and static, they don’t seem to be keeping any settings I give them through SADP.

I’ve also directly connected my laptop to a port on the NVR and set Ethernet to .254, and gone into camera themselves, in the few seconds before the IP changes, but then the IP changes, and it’s gone again.

Tried changing the POE switch to a new one, didn’t help.

Not sure if cameras are nackered? :-(

Thanks for any help

It just sounds as though you've not configured it correctly. The cameras connected directly to the PoE ports 1-8 will be set to plug and play getting a 192.168.254.xxx address assigned automatically. The issue is likely that you left channels 9-13 (which connect via the switch on port 9) as 'Plug and Play'. The best way to do this is in this order:

• Disconnect the switch from port 9 of the NVR - do this first!
• Using SADP (or browser) with a laptop connected to your PoE switch change the IP addresses. 192.168.254.109 for cam 9, 192.168.243.110 for cam 10 and so on.
• Do not reconnect the PoE switch to the NVR yet
• On the NVR go to the cameras set up. For camera 9 click edit, change 'Plug and Play' to 'Manual', enter the IP address as 192.168.254.109, enter the admin password and save.
• Repeat for cameras 10, 11, and 12
• Plug the PoE switch back into port 9 of the NVR
• The NVR will connect to the cameras at their statically assigned addresses

You've had the cameras set statically but the channels are set to plug and play. Because the camera has the same password as the NVR, the NVR just overrides whatever you enter. The above method gets around that.

Hi JB1970 - thanks for your help, your answer seems to have to have solved the issue…

However…

After following your advice, it all worked great until another power outage, then the switch must have lost its settings again.

The nvr has kept all the cameras on the switch on “manual” - but the switch seems to have lost its settings.

Do you have any advice on how we could keep the ip settings permanent?

Many thanks

What you're describing shouldn't be possible if you followed all of the steps I detailed. With the IP addresses set manually in the cameras and the channels on the NVR configured to 'manual' the NVR won't change the camera addresses.

I'm not sure what you mean about the switch losing its settings. There should be no settings in the switch.
