Well, I'm a believer in motion detector flood lights and cameras and alarms, and dogs and shotguns.
Motion detection floods and a camera is a pretty good idea.
Hatch has Clifford alarm system with ignition interrupt - adding alarm would be good when you can.
Here's a couple of pics of what the camera sees as viewed on a 20" LCD security system monitor. Lorex system.
Daytime.
Night time with security motion detector floods tripped on:
The central element to my security system is Field Marshall Casey von Ratzenhund:
Night Training......
The Bottom Line: Defensive only of course.
Already ran some jerkoff down for reaching through open window and stealing change from console one afternoon while I was mowing yard. Alarm went off, heard it from back yard and went inside to security system and viewed recorded video about 1 minute back and there he was. Saw which way he went and took a run down the street and gave him a little scare. This was before Casey started his training.
We really can't stop some slimeball from trying to steal or stealing our rides.
If they attempt it at my house, odds are my favor and I'll have their asses on DVR. In which case, I can probably make their departure a bit unpleasant - Casey will hunt now and I'm pretty good with a shotgun if he needs top cover.
I genuinely hope it never comes to that. But, some SOB comes on my property stealing, I will confront them.
Good luck with your setup and I hope your ride never gets stolen.
