Cameras Connected to poe switch, set as dhcp on

[normel]

Normally i always use the built in poe ports of the nvr. I have some installations where switches are used. So the camera's are set as static ip, then added to the nvr. However, each year, after the client changes modem ( cuz of change isp ) the ip range changes, so the cameras have to be reconfigured.

I can enable dhcp, and add them, but as soon as they get another op adress, the nvr will show offline. However i have seen situations, in which the nvr automaticly adds a camera.. OR is there maybe a setting to Settle that camera, that when the ip adress changes, its being re-added automaticly ? That will be a lot easier. As the NVR is alrdy set DHCP ( cloud )

Thanks

What would be a LOT easier and faster is to log into the new ISP-supplied modem/router's webGUI and change its subnet and (DHCP pool range if required) to match the subnet of the existing cameras.

Should take only a a couple of minutes as opposed to having to change all the cameras and go through that process "each year."

Thanks for the reply. I think that would be even more trouble, as you have to re-config the modem after factory reset.
By the way, after a modem change its a problem again. SO i think what you suggest is even more work

@TonyR suggestion is sensible and helpful.
I suspect you've misunderstood - it's actually a lot less work, less chance of errors too.

Assuming 8 cameras - one configuration change to the new modem base IP address
versus
changing IP address on the PC used to effect the changes, change IP address on 8 cameras, change 8 camera channels of the NVR, IP address of the NVR - plus an unknown number of other devices on the LAN that may have been set with a fixed IP address.
And also avoiding the need to find, update, and save your documentation that lists what's where on the LAN.

There is no need to "factory reset" the modem.
I've done it to probably close to 200 modem/routers since the mid 90's and it takes less than 5 minutes.

We assure it is much less work to change a new router to the IP address of the old router than it is to go into every device and change its IP to match the subnet of the new router.

Change ONE IP address or the IP address of EVERY device on the network.

Sure, changing the subnet of the modem is much easier. However, there are some modems here which doesnt allow to change that
And many of those setups are end users, ''accidently'' doing a factory reset

I remember there was a setting in the NVR, which added the cameras automaticly, i dont remember where. So after a change, it would re-add it. Thats actually what would be the solution in our case.
if not, we can still login directly to the camera by its SN to config the ip adres ( static ) then again re-add in nvr. This is lot more work, however, there is no need to go to client side , or no need for remote connection ( anydesk - teamv etc )

So the solution you suggested is actually easier, but doesnt work in my case

I remember there was a setting in the NVR, which added the cameras automaticly, i dont remember where.

In the Hikvision NVR HDMI/VGA interface, there is an SADP-like list of found devices on the LAN in the camera configuration menu which can be used to add a device to an unused channel, given the correct admin password.
But that's only for found devices that have not been connected to the NVR.

I have to think that your approach will be quite cumbersome and prone to error, possibly digging a hole when channels or IP addresses are mistakenly switched and puzzling over the result.

If you're worried about someone pressing the reset button on a modem, stick a label on it with a warning about what that would do.
