We've all heard them, sometimes in the middle of the night, always at some annoying moment. They honk, they wail, they flash - yes, we are talking about car alarms. A car is stolen every 25 seconds in the USA, costing drivers and the insurance industry over $8 billion dollars a year. With the huge aftermarket for stolen car parts used for repairs (notice how the most stolen cars usually also match the biggest selling models? that's because the stolen cars can be stripped and the parts used to repair all those other cars out there), car theft has long been a big business, and car alarms have evolved to battle the problem. At the most basic level, car alarms and their sensors, motion detectors, and pressure sensors are wired into your cars electrical system and monitor such things as vibrations, doors or windows being opened while locked, and any tampering with the ignition system. Higher end models come with microphone sensors which detect breaking windows and other sounds.
Door sensors are easy to use - they tie into the electrical system already in place that activates the dome light when a door is opened. With the alarm activated, this will now trigger the siren. The car alarm system is usually wired into your main car battery, but many also come with a battery backup incase the main battery is disconnected. If anything disturbs the alarm system, the alarm will sound (loudly!) and the lights will often flash as well. Of course, this doesn't stop the thief from stealing the car, but usually car thiefs are not looking to draw attention to themselves, and they will abandon their attempt and move on to easier prey. Another simpler gadget to deter car theft is something like The Club, which locks around the steering column making it impossible to turn the wheel. However, a number of reports have shown that a thief with a hacksaw can often get around this by cutting through the steering wheel to remove it.
