The electric immobiliser/alarm system was invented by St. George Evans and Edward Birkenbuel and patented in 1919. [2] They developed a 3x3 grid of double-contact switches on a panel mounted inside the car so when the ignition switch was activated, current from the battery (or magneto) went to the spark plugs allowing the engine to start, or immobilizing the vehicle and sounding the horn.

In the case of vehicle theft, the best deterrent to theft is in the installation of an approved vehicle anti-theft passive immobilizer. Many vehicles have factory-installed anti-theft units, which provide protection through the ignition system. Under the hood there is a computer that controls the operation of the engine.
SecuriLock, also known as Passive Anti-Theft System (PATS), is an immobilizer technology that Ford began using select Ford as well as Lincoln, and Mercury models. Each key have a radio frequency transponder embedded in the plastic head with a unique electronic identification code.
Physical security involves the use of multiple layers of interdependent systems that can include CCTV surveillance, security guards, protective barriers, locks, access control, perimeter intrusion detection, deterrent systems, fire protection, and other systems designed to protect persons and property.
In addition to the system itself, security alarms often offer a monitoring service. In the event of an alarm, the premises control unit contacts a central monitoring station. Operators at the station take appropriate action, such as contacting property owners, notifying the police, or dispatching private security forces.
EAS systems can provide a solid deterrent against casual theft. The occasional shoplifter, not being familiar with these systems and their mode of operation, will either get caught by them, or preferably, will be dissuaded from attempting any theft in the first place. Informed shoplifters are conscious of how tags can be removed or deactivated.
An intelligent banknote neutralisation system (IBNS) is a security system, that is used by banks, ATMs, retail establishments, vending machines [citation needed] and the cash-in-transit industry, to render stolen funds un-useable and easily identifable. Dye packs are inserted between bills in random bundles.
