This is the situation. In an enclosed communal area between two council flats there is a light that operates on some kind of sensor (heat/movement, not sure exactly). Now the problem is that it turns on the light when I move near the wall on that side of the flat (within the flat and door closed). There are no windows there. Just a concrete wall and a solid front door.
How is this possible? I thought that these things detected heat or movement, but couldn't 'see' through solid objects. I'd like to go to the loo without a warning light going on outside my front door.
Thanks for reading, any informed input would be great.
Read this bit only if you are bored or annoyed.
P.S. Hello, yes I'm one of those horrid people who sign up and post twenty seconds later. This place came up in a google search so I'm sorry but you seem like you might have some insight into this. Googling hasn't given me many answers. I know it might seem trivial and silly but I am really worried about this please forgive me.
