JGP...how are the beam barrier alarms working for you?
As ghosts are presumably energy and not solid, I wouldnt think they would be effective. Have you found them useful?
I have used them in a few places where they have been set off, the difficulty is when you get there there is nothing to see
so you have no idea what set them off. I guess the best method of using them is to set a camcorder up pointing at them
so when they do go off you can see if there is anything there. the few times I have used the camcorder with them they have
not gone off, but I hope one day they will.
It is interesting when they do go off as once I was the only person in the building so no person could have triggered them
I could see no animal and they had not been moved. I have used them at home as a trial and they sit there happy for hours
without going off on their own so I know they work ok.
You really need the camcorder and the beams working together in my opinion.
