My GF recently moved in and her kid sleep walks (11). The problem this is causing me is at night when we go to bed, I arm my alarm with motion downstairs. Last night marks the 5th time I've woke up to my siren screaming between 1-4am. The first few times I grabbed my gun thinking it was an intruder, just to get in the hallway, turn the light on and he's walking back up the stairs like nothing happened or once she goes into his room and realizes he's not there, she goes downstairs and he's standing there. Last night, he wandered downstairs and it set the alarm off, I jumped up, it woke him, scared the shit out of him....he screamed like he was being assaulted, the GF looks at me with this horrified face and says "omg help Charles"...I grabbed my gun, ran out of room, hit the light and once again he's coming back up the stairs....awake this time crying.
We have tried a baby gate at his door. He got used to it and started stepping over it in his sleep. We bought bells and wrapped around his door knob..he opens the door so lightly we can't hear them.
I could turn motion off downstairs and just leave the contact points on, but when I had the alarm put in, I selected all doors and a few windows, to save cost I added motion sensors in several places downstairs to where you can't move anywhere do there w/out setting it off. If an intruder chooses the right window to come in, I won't know he's there until he's in or in my face while I'm asleep. Motion is what gives me peace of mind when I'm asleep knowing there's nothing going on downstairs if I can't hear it. I could hardly get back to sleep last night after this shit happened.
