I have a garden that is accessible as I have a driveway at the back of the house. I want to leave my patio door open but it's a pain having to close and open it if I want to go to the toilet or upstairs for a short while.
Can anyone please point me in the right direction for a motion sensor (to be placed up high enough that the cat won't set it off) that will alert me if someone has attempted to wander in through the open door or a screen to allow air in and nothing else. Thanks.
