A key fob with a built-in radio receiver is available for some cars and allows a user to wirelessly control the alarm system to arm or disarm it. There are several different types of car alarm sensors being used on modern vehicles:. Shock and impact sensors are activated if the thief decides to break a window to gain entry.
These sensors can sometimes trigger accidentally. Some car thieves are pretty smart, though, and use special tools to avoid triggering the shock alarm when breaking a window. To counter this, some automobile manufacturers have installed microphone alarms that monitor loud, sudden noises in and around the car. Because of the way they work, these sensors can also give off false alarms occasionally. Tilt sensors stop thieves from towing the car off altogether. These sensors use devices filled with mercury which flow to one side or another in such an event and send electrical signals to the computer and sound off the loudspeaker.
Another type of sensor — the proximity sensor, scans an area around the car for movement. These sensors are designed to only capture movement very close to the vehicle and at a certain speed. This is useful because car thieves often like to cut power to the vehicle first by snipping the battery cables under the hood. A sudden loss of power to the battery like this would activate the auxiliary battery power and send a signal to the computer which will trigger the alarm.
Car alarms can have some problems that you should be aware of. A lot of the time, the issue is due to old age or bad internal wiring.
The remote entry system on a car can become faulty when the battery in the remote loses power. Another annoying issue is where the car alarm randomly goes off by itself; often in the middle of the night. Bring it in as soon as possible, as your car is vulnerable to thieves during this time. If you suspect that this is the case, have the car inspected immediately by an ASE-certified automotive technician.
When shopping for car alarm installation, make sure that the provider posts all relevant policies such as labor rates, warranties, guarantees, etc.
Check if it specializes in certain types of vehicles or if all models are covered. If your goal is to simply invest in basic protection, a car door sensor should be enough. But if you need more advanced protection in a high-crime area, then go for an alarm system that has more detection methods. Notify me of follow-up comments by email. Notify me of new posts by email.
