This is actually a wishlist topic with much discussion on the subject. I posted a suggestion in that topic to be able to flag the MAC of a stolen cam for police to track.
I am wondering if Wyze has this ability.
But, the cams are probably gonners. The service, however, stays on your account. Once you get an answer from Wyze on the tracking\flag for the hardware, you will most likely be replacing those cams and deleting the old ones from the app. But don’t do this until you download and save all the pertinent video footage associated with those cams. Then assign the replacements to your existing subscriptions.
