My husband took two walks through our neighborhood in the middle of the night wearing his underwear and bare feet. I got a Ring camera for both doors. The front door I placed the camera inside the front door so when he walks into the field of the camera while it is “armed / away” I have a very loud ring on my phone. I keep the phone by my bedside all night. Our back door goes int the garage so i put the camera in the garage facing the door (didn’t have a place to plug it in inside the door.). Anyway…. I have a phone app that runs it all and it’s all good until a hurricane comes through and takes out our power / WiFi. Didn’t sleep very well those nights. So far….. hubby has only wandered out in the night / early morning so I disarm the system during the day but you can set it up as needed. Hope this helps.
