In reply to johncoxmysteriously:
A friend has a 'Snooper' stuck to his windscreen and its the most annoying thing in the world, possibly the whole universe?
It picks up just about everything - anything IR controlled e.g. motion activated doors, meaning driving through a town is a nightmare. It will only pick up stuff line of sight - meaning if it picks up a remote speed camera, it can already see it and therefore the camera can see you and you will have been caught.
It gets very angry in cities and stuff when its picking up 'K-Band Radar' EVERYWHERE!
Plus they are banned if you go to France!
