Car Alarms are things that we have to have but don't think about too much. Don't get me wrong. There are some excellent reasons to have a sound alarm system in your vehicle. It can help you save money and time by alerting you to danger before it gets too late. But don't let those good reasons overshadow the potential drawback of not having an effective system. I'll show you how to find out if your car needs an alarm.
Car alarms are generally electronic devices placed in a car to prevent theft of its contents, the vehicle, or both. Car alarms work by generating high-frequency sound waves when the proper conditions for initiating it are present. These conditions usually include at least one other car, moving objects, wind, or even dust particles.
Car alarms function by creating a false alarm whenever these conditions occur. If there was no dust, for example, or another car coming up on your way, there would be no reason to set off the car alarms. This is why most stolen cars have such a feature - they were set off by someone who didn't expect to see them or someone who didn't hear them being activated. The result is that one thing will always trigger off the alarm - someone trying to steal your car.
Most modern vehicles come equipped with factory-installed car alarms, but if your car is over ten years old, it is still a good idea to keep it in an unprotected place like your trunk. Some thieves target older vehicles with sedans and have been known to strike when the gas light is turned on. Older cars with factory-installed siren systems are generally harder to hijack. Still, this is probably the best option if you can't get in the car or disable the alarm by unlocking it with the keys and pulling it out.
One of the more modern car alarms has recently been introduced onto the market - the hood sensor. These are designed to detect a person, animal, or another moving object on the road ahead and sound the alarm. This is great, but the problem is that many older cars do not have hood sensors and will therefore not trigger this type of alarm.
Another new type of car alarm is that the tilt sensor detects objects on the road moving in a specific direction. If someone is running into your lane, the alarm will sound if something is wrong with the tilt sensor. This is different than simply moving in front of a car and activating the alarm. There are also several different ways that a thief could start this type of system. To figure out the best way is, it is a good idea to familiarize yourself with the alarm system on your vehicle and the different sensors in your car.
One of the common causes of alarm failure for most newer vehicles is simply someone being too loud. If you have your windows open and someone is screaming or shouting into the microphone, you are going to hear it. The same goes for someone who is banging on your car, shouting things, or using profanities. If you have your windows cracked open, it is still loud, so you will hear it if someone decides to break into your vehicle.
The last primary type of car alarm that needs to be considered is that of false alarms. Some thieves will utilize fake detectors to catch you by surprise, so it is a good idea to make sure that your vehicle systems have additional features like this. In addition, make sure that the different elements that you have in your vehicle systems will work! If not, and you hear a false alarm, you may want to consider contacting a professional.
