Just heard a car alarm go off, and checking out of the window to see if it was mine, discovered that it was. Turns out it was also my next door neighbour's ...

The car parked between them, a track-modified-and-tuned imported MR2, owned by the mechanic neighbour on the other side, had just started up.

With a combination of the cold weather and the race exhausts, together with the advanced ignition timings, the start-up blart must have been just the right level of vibration to trip the sensors on our cars! He was rather apologetic. [grin]

Heh. Bikes, especially big V-twins like classic American machines running with open pipes, can hit that frequency just right ...

Oopsie! My friend Nigel once set off a whole floor in a car park, by burping.

*giggle* That's rather more impressive than getting a wineglass to crack.

Wow! The car park must have had some pretty impressive accoustics...

A lot alarms have the ultrasonic sensors set far too sensitive. They're meant to detect a window being broken, not just the car moving slightly due to a loud noise or gust of wind.

I've seen some set off by thunder!

[grin] I think this might only be the second time that I've heard mine go off (and the first time was when I had to use the key to get in because the battery in the remote needed changing - if you open the door without disarming the alarm, you have five seconds to start the engine, or the alarm goes off - I took about seven, so got two seconds of alarm ...).

We used to set them off with fireworks at my brothers...... :)
