My network was changed recently and now I am not sure what I need to do to bring my cameras back online. I have several, most are hard to get to. Do I have to completely re-register each camera to get them linked up?
I think so yes.
Unfortunately there isn’t any way to remotely change the SSID on the camera. You’ll have to do them one at a time and physically at the camera reset, scan QR code, etc
Can’t you reconfigure the WiFi/router to use the same SSID and password as before?
That’s what I did last time I replaced my router. Way too many devices in the house to redo every one of them
20 Years from now: When I was your age we didn’t have any new fangled neuronet. I had to walk uphill both ways, and resetup every single device…
