MAYBE?
When I am at home nothing happens but when I get to work it says it has detected a ghost I even caught one in the parking lot outside of the building where there was no electrical source and just for fun I tried it inside and it found another one it only works it seems when Im at work not when Im at home could it be because I have a ghost at work and not at home,not sure??
NOT TOTALLY CONVINCED about
