My wife and I have a warehouse in a somewhat secluded area where random people come to hang out in the parking lot after dark. There was a burglary a few months ago and a couple of lazy attempts on several units here as well. I have a good detection system and video setup, so we know whenever people get anywhere near our building. I call the police when someone is there, and they have made some drug-related arrests, caught a couple "looking for some privacy" in the deputy's words, etc. However, the police are often slow to respond, and so people are frequently long gone by the time someone shows up. While I would prefer to have the police show up to check out what a suspicious person is doing, I primarily would like to just make them know that someone is watching and make it uncomfortable for them to stay there so they won't come back or tell their friends that this is a great place to hang out or break into.
I'm working on hooking up some loud PA speakers and setting up a system to remotely connect to them, but I was also thinking that it would be great to have a spotlight I could control remotely so I could just light up a car if it parked back here. This is as much for entertainment as practical value. Any suggestions?
