This sort of thing can be done with much safer infrared LEDs, but you will then have the problem of focussing the LED beam. Commercial home security systems are much better engineered, and if you are really concerned with your home security, I would go out and buy one. If you are just interested in playing with the electronics, then email me for safer ideas.
