i have the LEA 826 pagar alarm!
can remote start up to 1500m away

(havent tested that far though).

so anywhere in this distance and the alarm goes off, the pager will tell you about it! even to the extreme of what part of the car, ie, boot, engine bay, door where the has sensor been broke.

can get lots of add ons with the alarm to, i got the remote pop up light on the key fob as well! so can pop up the lights without even getting into the car! COOL!!

very handy bit of kit! especially if you say drive to work, and are only a few 100 meters from the car while in the office, you wouldnt hear the alarm, but the fob would tell you its going off!

(fog vibrates and/or lets off a small siren in the fob)

love the alarm!

can be used in winter for starting the car up from your bedroom, so when you get in the car its nice and warm in there!

list goes on!
