I would like to detect motion over a larger distance then the standard 30ft range that PIR indicate that they will function in. Something more like 100ft would be more to my liking. I looked at laser detection but all I seem to find is more of a laser break detector rather then motion detector. Any suggestions?
Think you'll have to go to a commercial unit http://www.interlogix.com/_/assets/library/1036522%20B%20AP633A%20PIR%20Installs.pdf http://www.surveillance-video.com/ap633a.html
