Mostly the scene when they try to go the back door and here gun fire. Simulate that REALLY LOUD! With the lights BAKING the perp and Many Many Many a camera to catch all the action. I wouldn't chase him. Just post on u-tube and share on social media. Also the cheap pre-paid phone Idea would work too. If you want you could just add the line to your current plan for cheap. I know i can get a carrier compatable phone cheap, sim card like $20 and service would be bout $20-30 a month for the line with data. If it is android based add a couple tracking apps (cerberus I'd recommend cost is $5 for 5 devices but worth it) and there ya go. IF you add lookout, it has a low battery signal flare which it will tell you it's last location before battery dies. This is good if you keep it out side with out a charger. Speaking of charging power it some how off the projector as some else mentioned is a good idea. NOW the down side is what is the temperatures this device is exposed to? Too cold or too hot the battery will not like you.
