Heya modman shut up . It's true those are so good alarm systems. If you have some property and have your car out in the open the best alarm is a guard dog at night. Some other good systems would be for sensitivity or what you could do is go to a specialist that wires it to where when someone tries to get into it it does not make a sound it just makes a sound for your car alarm remote so noone suspects you'll be behind them when they are breakin into your car. Good luck.
