I have the same problem, on 8 cameras. (Mix of multiple: C210, C520WS, C310)

I have earlier activated the option "Static IP" to ON, and now needs all cameras to optain IP via DHCP from my gateqway instead.

Turned all camereas "Static IP" to OFF, and expected them to optain IP from DHCP.

But all cameras reverts to "Static IP" = ON, after Power sycle or reboot from settings.

Removing the "Static IP" setting is not possible as it seems.

Seeing this on 8 cameras, suggests it is a bug.

  @Wayne-TP it's not the same situation.

its enabling the static IP and CHANGING the IP.

and even if I enable static IP, its changing the IP, even static, after reboot, sometimes.

I enable static IP with 192.168.2.3, when reboot, it changes to 192.168.2.4.

the problem is not static IP to be enabled, but changing the IP by itself, even with static IP. And this causes to drop connection with external systems.

I'm already using the last version.

thanks.

Do you have static IP settings on any other devices? Please check if the IP address 192.168.2.3 is assigned to any other devices as well. Normally, if you set a static IP on the device side, the router won't detect conflicts when reserving the address.

No, there is no other device on the same IP, I'm sure about this.

Anyway, the problem is that the camera is setting other IP iself, even with static IP.

Even if there is another device with same IP, if set static, it must be static and NEVER change, not even if conflict.
