Buying Guide


Buying a car usually does more than help simplify your life regarding personal transportation and lifestyle. It also turns you into a potential car theft victim, and as the statistics are showing a continuous rise of this type of crime, it is advisable that you secure your property with the best car alarm system your money can buy. You will find below a list of the most important features one has to consider about a car alarm system, as the market is flooded with models packed with multiple features that make it difficult for an unadvised buyer to choose.

CrimeStopper SP-101


As car thieves refine their methods all the time, the classic break-in through the driver’s door is almost obsolete. This is why manufacturers have improved alarm systems with complex sensors so that any attempt at stealing your car can be signalized immediately. Most car alarm systems have built-in shock sensors which trigger the alarm based on impact. You can maximize this protection with a dual stage shock sensor that will cause a light warning when the shock is small or a full-on alarm when the shock is notable. A glass breaking sensor will recognize the frequencies in glass breaking sound, while a motion detector works like a radar, sensing all motion in the vicinity of your car. This particular sensor type is, unfortunately, prone to make your car alarm go off for no reason. Last, but not least, you can now find alarm systems with tilt sensors, to make you aware of your car being towed or put on a car jack.



Remote control

Also known as keyless entry, this feature allows the user to lock or unlock the car doors, to arm and disarm the alarm and even to release the trunk, all with just the push of one button. Having a remote control transmitter saves you the time and energy consumed in using the car key every time and eases the access to your vehicle when you have your hands full with luggage or groceries. Keyless entry systems usually have a panic button which comes in handy in case of emergency or danger, but also if you have trouble locating your car.


Thief stoppers

There are a few features that can actually stop a thief to leave with your car. One of them is the door deadlock, which means that once the glass is broken, the doors of the vehicle will block, preventing the thief from getting inside. A dynamic codes feature will frequently modify the codes to the alarm system, making it difficult for the thief to grab them. Many alarm systems come with a starter kill option which interrupts the ignition circuit, keeping your car from being hot-wired. Other great thief thwarts are the biometric fingerprint reader, the GPS tracking device, or the driver door unlock, that will block the other doors of the vehicle.



No matter how complex your system is, your remote cannot work if you are out of its range. This is why you have to consider this feature carefully, based on your parking habits and needs. A wider range will always be better as you will be able to lock and unlock your car from a greater distance. This feature is also useful in large parking lots where using the panic feature can help you locate your vehicle.

Viper 5806V

Two-way remote

What happens if you are parked in a very noisy area or you have gone too far away from your car to hear the alarm? Usually, the more time you spend not knowing about the theft, the fewer chances you have to recover your property. To prevent this, you could consider a remote that notifies you whenever the alarm system is active. Moreover, you can use it to control the car from afar, start the engine, pop the trunk or locate your vehicle before you reach it.
