I recently came up with a concept using basic UL approved technology which really is no big secret so patenting is not an issue, If anyone wants to patent it go ahead .. Atleast I can simply buy the kit instead of building it.
Anyway I provided a link to my video made some time ago for the heck of it, The issue in my area is rooftop theft stealing the copper from the AC's .. so I came up with a prototype generic concept but applied it to rooftops.
Motion sensors with lighting controlling a contactor which engages a horn strobe .. not foolproof but it does work, no units have been stolen sense.
