We have the door locked and know that is not a great solution, and are looking for a permanent solution. A few times when the door has been unlocked my dad has slipped out and we've found him wandering the neighborhood, on his way somewhere although he's not sure where. Once it was in the middle of the night and the police found him. My mom is hard of hearing and may not always hear the typical door alarms designed for Alzheimer/dementia patients, so we are trying to find out what others in this sort of situation have done. I feel like it can't be that unusual. Note there are others that live at home and would hear an audible alarm. but we need to find something for my mother since she is the primary caregiver. Thanks so much in advance.
