Hi all, I have read a lot of user and installation manual of many common manufacturers and models but... Is there a camera model able to automatically switch from ethernet connection to wi-fi if link goes down?
Not that I am aware of.
I don't think that it is a failure mode that they cater to.
Some will record to a microSD card in the camera, and when used with typically the more advanced software solutions restore the recordings back to the central recorder when the network is restored after downtime.
