Who Should Buy a Car Alarm System
An alarm system is an ideal choice for anyone who is worried about their vehicle being stolen or broken into. Given that nearly one million vehicles are stolen each year, according to FBI estimates, installing an alarm system is a pretty cost effective way to protect your investment.
If your vehicle has been broken into or stolen before, an alarm system can provide added peace of mind that your automobile is safe and sound. Additionally, a lot of insurance companies offer their customers lower rates if their vehicle is equipped with an alarm.
You might also want to install a vehicle alarm system if your vehicle did not come with one. While many modern vehicles come with an alarm system pre-installed, older vehicles are lacking in this technology, and could benefit from the added security provided by an aftermarket alarm system. They can also provide improved performance over OEM alarm systems.
Some alarm systems for vehicles include tracking devices, which allow you to easily find your vehicle in the event that it ends up stolen, and sometimes even deactivate remotely.
And if you’re looking for information on other aftermarket products, such as finding the best wheel covers, the best car covers, or the best car speakers, we have in-depth buying guides that can help make your decision easier.
Important Features to Consider
Not all alarm systems are created equal. An alarm system should be easy to use and reliable. Here’s what to consider when evaluating the options in search of the best alarm system for your vehicle:
- One-way/two-way. Arguably the most important consideration when it comes to buying an alarm system for vehicles is whether or not it is a one-way or two-way system. One-way systems use one-way communication between the remote control and the vehicle to perform commands. They are generally more affordable than two-way alarm systems. Two-way alarm systems for vehicles feature a remote control that communicates with the vehicle, and the vehicle communicates back to the remote control. This instant response gives people peace of mind that their commands have gone through, but they are often considerably more expensive than their one-way remote counterparts. An LCD screen provides visual confirmation, and can be quite handy.
- Sensors. Vehicles can be tampered with from the windows, trunk, or doors. Having sensors in each of these possible tamper areas can provide added protection to your vehicle. Window sensors respond to the sound of windows or glass being broken or opened, while tilt sensors will sound the alarm if your vehicle is lifted at a certain angle — such as being towed away by a thief.
- Active/passive activation. Active alarm systems require the driver to arm and disarm the system (usually with a remote), while passive alarm systems arm and disarm based on proximity to a special fob or remote, or when the ignition is turned off and the last door opened is closed.
- Encrypted transmission. While the classic image of a vehicle thief is one of a person with a crowbar or slim jim, many thieves nowadays use state-of-the-art signal hacking equipment which allows them to bypass a car alarm’s digital security features. A system with encrypted transmission is much more difficult to hack, and therefore helps keep your vehicle more secure.
- Remote start. The ability to start your vehicle remotely is convenient to cool in the summer or warm in the winter, and isn’t always built into a system. Sometimes you just need another component, while other times it is already included. Systems with auxiliary outputs allow for the expansion and use of remote starters, and other features.
- Mobile app compatibility. There are some vehicle alarm systems that offer companion app compatibility, so you can keep tabs on your vehicle, or perform commands from your mobile device.
- Price point. Finally, consider how much you are willing to spend on an alarm system. Alarm systems vary in price from $20-$400 or more.
Frequently Asked Questions
What is an alarm system and how does it work?
An alarm system is a series of sensors that alerts you to tampering. It works by being activated (either actively or passively) by a remote. Most alarms have a flashing LED light that provides a visual alert to would-be thieves that your vehicle has an alarm installed, which is often an effective deterrent. If a thief attempts to tamper with the vehicle, the system gives off a warning chirp or full siren blast, depending on which sensors are tripped and how severely. A 2-way alarm system sends a notification to the 2-way remote in cases of vehicle tampering. You can deactivate or disarm the system using the remote when you return to the vehicle.
What can trigger a car alarm?
What triggers a car alarm depends on the types of sensors the system has. Vehicles can be tampered with from the windows, trunk, or doors. Having sensors in each of these possible tamper areas can provide added protection to your vehicle. Window sensors respond to the sound of windows or glass being broken or opened, while tilt sensors will sound the alarm if your vehicle is lifted at a certain angle — such as being towed away by a thief. Door sensors activate when pried, and shock sensors alarm if someone hits, jostles, or otherwise moves the vehicle.
Will a car alarm stop on its own?
Depending on the alarm system, sometimes a car alarm that has been set off will stop on its own after a few minutes, or it might stop for a period of time before alarming again. Many cities now have requirements for home and vehicle alarms to shut off after a certain about of time so as to prevent annoying others in the community. Generally though, you will need the fob or remote in order to deactivate a car alarm. An alarm will also stop on its own once the vehicle battery is dead.
Can a low battery cause a car alarm to go off?
Yes, a low battery can cause a car alarm to go off. However, many car alarms have been designed to detect low battery levels, which can help you know if it’s time to replace it. If your battery is low or dying and you try to start the vehicle, it can cause your car alarm to continue going off. This problem can easily be solved by checking your battery from time to time to ensure it’s in good shape.
