The abbreviation for enforcement is "enf." The word "enforcement" means to compel or force obedience or compliance to a law or rule.

Dutch company Gatsometer BV, founded by the 1950s rally driver Maurice Gatsonides, invented the first road-rule enforcement cameras. Gatsonides wished to better monitor his speed around the corners of a race track and came up with the device in order to improve his time around the circuit [2]. The company developed the first radar for use with road traffic, and is the world's largest supplier of speed camera systems. Because of this, in some countries all makes of speed cameras are sometimes generically referred to as "Gatsos".
