Which type of alarm sensor to use

[rcx106]

I'm soon installing an alarm in my Vitara and trying to decide on which type of alarm sensor to use. I've had no luck with microwave sensors, if I set the sensitivity higher I get false alarms, set it low and I need to wave my arms and punch the air to set it off. Never could find a decent balance point, even after upgrading to a decent branded sensor. I'm wondering if ultrasonic sensors are any better?

Might not bother with a sensor at all, I'm mostly just in it for the remote central locking. Just wire up to the door switches and f**k the microwave or ultrasonic sensors. I just don't know if they are good enough.

You have solved your problem - Buy a remote central locking unit

Bought a Right Click alarm because I love that it comes with a flick out remote that I can transplant my key and transponder onto. The unit was cheap, £35, and does remote central locking and is an alarm. So yes I could just forego the alarm functionality. Or just have the alarm triggered by the door switches and forget the ultrasonic or microwave sensors.
