I have a DVR with 8 cameras that IS NOT linked to the cloud via the subscription.
However, it stores about 10 days worth of 4K video and then rewrites overtop of the oldest. I didn't want the cost of monthly subscription but wanted the ability to review it if anything happened in the neighborhood. And boy, we've have several incidents over the last 8 years we've had it .. of which 2 were used as evidence by the police. (car theft, hit and run on a parked car)
I ASSUMED that ring cameras all connected to the web for storage.
Would the perpetrator have inside knowledge that the camera WAS NOT CONNECTED to the cloud? I mean, you would be seen smashing it if it was and smashing it would do no good at all.
