The cameras can never be turned off (unless you have a hardwired power switch for the camera). They always record when there is motion. You can turn off the alerts but not the video recording caused by the motion.
(there is one exception - the stick up cameras allow video recording to be turned off)
From my perspective this is a huge “privacy” issue. Even Alexa can be turned off. All the cameras should have the same off switch as the stick up cameras.
