My wife has FTD with aphasia. I never know when she gets up while I am sleeping. I am afraid she will try to go out while I am asleep. I have looked for an alarm system that would wake me if she tries to go out while I am sleeping. I need an entire system with door alarms, perhaps a door mat type with a bed shaker with an audible that would make enough noise and a light flasher. It would have to be at least 100 db for me to hear it without my aids. And expandable in the future. I am open to look into nearly anything. Currently I am looking for chain guard with alarm for use while I am awake. Anyone have any experience with anything like this?
