I’m moving in as a carer with someone very mentally ill who generally needs supervision going out. Sometimes they try to abscond in the night, causing significant risk to themselves (so far resulting in several A&E visits). In the place they’re currently staying, the main carer sets up a physical barrier by the door each night so that any escape attempt will wake them up with chairs falling down. I will not be able to do this because blocking the front door would be in the way of the bathroom.
I’m looking for an alarm I can set from inside that will go off when the door opens if not first disarmed. Bonus points if it can phone me when set off so I hear it even if I’ve gone out, I’m not expecting to find that though.
Also I’m in the UK, so needs to be something I can purchase here or reasonably import
