It may be a “modes” setting under the “smart” option
Check which mode you’re currently on (likely “home”), then go through each camera and disable alarm
Yes like dav1289 says. tap on smart icon bottom of home page then it will either show your camera or home base (tap on home base if you don’t see your camera at this screen ) then you will get the “mode” screen tap on gear icon and then your camera and there will be several options for the camera toggle off alarm there. If you use the “home”. & “away “ option you can change the away settings to have it off or on when you’re not home. I will load a screenshot in another reply
