Car Security Systems Deliver On Options
Just about every system out there has its share of pros and cons. Still, with auto theft numbers high, any type of security is considered better than none. In the grand scheme of things, any security system that can slow down the bad guys or alert them to the fact a vehicle will not be an easy mark can be quite useful. The unfortunate fact of the matter is that anything that can be done to make a car look and be less easy to steal can prove to be a very good deterrent for theft. Thieves generally want a vehicle that will only take seconds to get into and drive off with.
Some of the top system styles out there that can help get this job done include:
Siren or horn-based systems – Also known as an audible system, this type of car alarm will activate with loud noises coming from a vehicle if a connection is broken. Horns will go off, sirens will sound and lights may even come on. This type of system can include a number of different activation features, including those that signal the alarm if the door is opened while the system is armed. The basic idea is to generate attention toward a vehicle so would be thieves are either scared off or caught in the act. Unfortunately, the sound of car alarms going off has become so commonplace that many passersby ignore them. This can work against a car owner. Silent alarms – This type of system gets rid of the noise associated with an audible system. Instead of trying to scare off a thief, it sends a page to the car owner that a theft is in progress. Silent systems can be very useful for keeping the peace, but they can pose some problems for owners. They might, for example, respond to an alarm personally and interrupt a thief in the act. Steering wheel locks – These low-tech devices do provide a basic level of security. They can deter thieves by making it very clear that a car will not be an easy mark. They can, however, be removed by skilled auto burglars. Kill devices – Ignition immobilizers stop a vehicle from starting if the system is activated. These devices can be an excellent deterrent for theft in that they disable a car from physically operating unless the right key is put into the ignition switch or the right code is punched into the vehicle.
Car security systems are not foolproof devices, but they do make vehicles less intriguing for would be thieves. When it is time to fight back against crime, any preventative step is worth taking.

Car Alarm Systems
Car alarm system is the best way to reduce the increasing crime and keep our new cars protected. It is a system loaded with sensors, sirens and signals that gives a warning alarm in case of car theft. The basic version of the car alarm system comprises of a switch on the driver’s door that is wired to the siren. If anyone opens the door, siren will start wailing.
As India is coming up with new and high tech cars, the anti theft alarm system is also getting sophisticated and better in all aspects.The latest Indian cars are equipped with modern anti theft systems comprising various kinds of sensors, siren, radio receivers, auxiliary battery and computer control unit with a sophisticated and more secured output. Different sensors loaded at different places detect the motion, touch and pressure on the car. Siren is used to yield sounds in case of car theft. Radio receiver helps in permitting wireless control and keeps the owner informed. Auxiliary battery works as a replacement if the original battery is not charged up or functional. Lastly, all these working and operations of the system is controlled and monitored by the computer control unit.
Sensors are powered controlled devices that receive and respond to a stimulus. In modern car alarm system, there are mainly five different types of sensors that respond to various different stimuli or actions based on which part of the car is targeted.
Following are some of the most common types of sensors loaded in modern car alarm system:
Car-Alarm Door Sensors
This is the basic sensor that responds when a car thief opens any door of the car. Immediately, the car owner gets a signal. The sensor is either connected to a siren or to the interior lights. When the thief opens a car, switching mechanism built in the car door transfer electricity to the interior lights and alerts the thief.
Car-Alarm Shock Sensors
Shock sensors help a great deal in deterring thieves and vandals. If a car thief hits or moves any car, these sensors send a signal based on the kinetic velocity of the car. If the car receives a shock and feels an unidentified change in the intensity of motion, a warning alarm beeps. In some cases these sensors are also linked to the fuel engines wherein after detecting a drastic change in the intensity of motion, fuel engine automatically stops supplying fuel to the engine.
Car-Alarm Window and Pressure Sensors
These sensors are the main detectors for detecting broken windows. If a car thief hits the window of the car and breaks it down, these sensors detect the sound or the air pressure of the car. These sensors are connected to a microphone which in turn monitors the air pressure and in case of any variants, the air pressure fluctuation converts to electric current which is send to main controlling unit. In this way, specific sound will trigger the alarm and keep the thief away.
Car-Alarm Motion and Tilt Sensors
These sensors become functional when a car thief tows and drags the car to a safe place. Such sensors comprise o perimeter scanners that monitor any tilt, lifting and even slight movement of the car. Through these scanners it is also easy to monitor all the activities within a predetermined perimeter of the car park. Once the motion is scanned, the radio transmitter sends signal that are reflected by the receiver monitors. Similarly, tilt detectors are series of mercury switches made up of two electrical wires and a ball of mercury. This series of switches conducts electricity. In case of any car tilt or lifting, these electrical wires change the flow of circulation and warn the thief.
