Currently most common in use are the
Wookee radio control unit (anyone know who makes this?)
Sega radio controlled car alarm
Qusan Wireless doorbell
These have hundreds of coded pulse permutations and are hard to jam.
Experience from Ulster showed that if you deployed a 'jammer' the
insurgents just figured out the range of the jammer and planted a linked
secondary device down the road at just about where you would be when
your 'jammer' came in range of the detector.
The car alarm device operation is obvious - how many times has your car
alarm gone off when your car has been parked on the road and a big truck
goes by?
Various pull-actuated devices -Impossible to jam and mainly used by
suicide bombers...
If anyone is really interested in this stuff I have images.

Talking about protecting military vehicles from IEDs - you have to
remember that a lot of these are roadside devices rather than the odd
mine so you have to protect from the side rather than the bottom.
Protection can be the simplest stuff - I know this having survived a
300lb IED going off under a landrover fitted with fibreglass armour...
mind you we never found most of the armour afterwards it had simply
dissapeared in the explosion.
