The technical starting position
Old cameras can continue to work, but addresses, passwords, channel names and app links must be reconfigured or otherwise set up on a new NVR.
advice
Replace NVR and migrate cameras
A recorder swap is an opportunity to improve storage and management, but requires a controlled migration of cameras and access.
What you calculate or measure
Create a list of cameras, connections, desired storage period, accounts, and critical images. Determine whether existing recordings should still be stored or exported.
The intervention that fits
Plan the switch with a clear sequence: prepare the new recorder, transfer one camera at a time, verify the recording and only then turn off the old routes.
Proof that it works
Check each channel, live view, timeline, app and user rights on the new NVR. Provide a new overview of channels, storage and management.
Frequently asked questions
Can I bring old images to a new NVR?
This depends on equipment and export possibilities; determine this before the exchange.
Why not transfer all cameras at once?
Phased working makes errors and failures more visible and recoverable.
