Wireless Motion Sensors.

Thank you very much!!

Most of the sensors that were hacked there are out of production and have been for several years. You can buy motion activated camera controllers from several sources but they can get rather expensive for your purposes. I'd recommend getting a less expensive battery operated PIR and tapping off the output pin of the opamp. on an 8 pin it is normally pin 7, however on a 16 pin you may have to download a Data sheet for the particular device since my brain has decayed and I can't remember which pin it is.

There's floodlights available at http://www.smarthome.com/4080xt.html which will send an alarm when they activate using your power lines. They also sell a X10 motion detector without the lights for about $25. It seems that this would be the easiest way to install what you want without stringing a lot of cable. Interfacing a PIC to X10 seems fairly easy although I've never done it.

i was just doing some reading in here and I came across your post. I have alink for you. it is a toy that can be hacked to suit your needs. one main problem with it is it's reliability. but it might ave you some time and money. i modified the reciver board to communicate with a pic. The receiver board is a lot smaller then the big plastic toy housing, so it will fit in a much smaller box. the sensors/transmitter are smaller then hockey pucks and have decent range. maybe 20-30 meters
have fun.
