Alarm Systems For Your Car
Did you know that a car is stolen every 20 seconds in this country? That is why it is so important to have a car alarm so that you are able to protect your car from being stolen. There are also a variety of thieves who may not be after your entire car but possibly, the wrapped Christmas presents in it or the brand new boxed television or stereo you just bought. Or, there are thieves who own tow trucks who simply lift your car, and take it away.
The first stolen car occurrence took place in the late 1800s. The first car alarm was installed in the door of the car. However, car alarm systems have come along way since then. Some systems are so sensitive that they go off when someone inadvertently touches the car, or a ball accidentally bounces into it. The alarm is set off by sensors that have been triggered.
Car windows are usually the point of entry for thieves. They merely bust out the window and steal the car. There are window sensors that can be set off to alert you that your vehicle has been broken into.
There are shock sensors which are very sensitive. They have charged rods which will move and strike each other which will set off the alarm. They are super, super sensitive and will go off even with slight disturbances.
Most car alarm systems have an array of sensors that go off when circuits are severed. When a door or electric window is opened the alarm is set off.
Some systems are programmed to emit a piercing sound that will scare off any thieves and will alert anyone in the area that a thief is attempting to steal a car. Consequently, many thieves will run away.
There are some systems that you can program yourself to sound off a specific pattern that you recognize so that you can determine if it is your car that has been broken into.
There are also devices known as pressure sensors which are set off when there is a difference in air pressure caused by a broken window or opened door.
Most car alarm systems come with a transmitter small enough to fit on a key chain. They are similar to toys which have remote controls. The devices use radio waves to send signals. The portable device also allows you to turn the alarm system on and off. The system also allows you to open your unlocked car by activating the locks.
In the coming years there will be a great deal more innovation. Technology has advanced so that we have GPS tracking devices which may be used with cal alarm systems so that you know where your vehicle is at all times.
