Claymore mines
Laser tripwire mines are highly discouraged by the Geneva convention. Typically, real claymore mines are detonated with a wire and switch.
Do Claymores have motion sensors?
The compact camera unit is mounted atop the mine, enabling command-detonation upon proper identification of the target. A motion-detecting sensor can be added to ensure that no one sneaks past the mine and there's even an option to record video feedback with GPS positioning.
Can you survive a claymore?
If you are a three armor operator and have rooks armor you can survive a claymore if you see it right as you walk into it. If your reactions are good enough you can move back just far enough to survive the explosion with a little bit of health.
