1) Sensors

It is common for someone new to car alarm systems to be concerned with just door sensors. The door sensors prevent intruders from going too near the door, hood and trunk of your car.

However, car door alarm sensors alone are not enough to stop car thieves. The top car alarm systems which we reviewed in this guide include other forms of sensors which stop thieves from carrying out their agenda. 


There are impact sensors just like that on Avital 5305L (best car alarm for vandalism) which prevent harm from coming to your car. Any impact on your car whether light or heavy is reported directly to you.

Moreover, the sensors on alarm system for car differ based on their level of sensitivity. Some sensors are more complex than others. Moreover, you have to take note of this before purchasing any car security alarm.

2) Carjack Protection

Imagine parking your car outside only and your car alarm system send you an alert that someone else is driving your car. Shocking, right?

However, this scenario can be stopped if your car alarm system has an anti-carjacking feature. Only the best car alarm systems feature it, and the quality differs from product to product.

The function of an anti-carjacking mode is to ensure that the individual who steals your car doesn’t get far with it. This feature kills the engine of the car.

Depending on the quality of the product, this anti-carjacking mode combines its engine-killing switches with alarms and lights.

Such that the car begins to blare high-pitched sounds that further prompts the car thief to abandon the car.

3) Car Alarm Prices

Always being asked is how much is a car alarm or which car alarm cost range should i get?

This is one factor that you have to thoroughly consider, the minute you decide to purchase a car alarm system. Do not just jump on the first car alarm system that matches your budget. 

That would be a very wrong decision. If you jump on the cheapest car alarm system on the market; the quality might be so low that it doesn’t even last a year.

At the same time, buying the highest priced car alarm system on the market offers no guarantee for the best quality.

While you consider the price tag of the model, also weigh that price against the features and specs of the product. This will ensure that you don’t end up spending a lot on a a car alarm system.

4) Remote System

Another important consideration is the remote system. Most of the best car alarm systems reviewed in this guide offer 2-way remotes.

This kind of remotes ensures that you have an easier time controlling your car and receiving input about the condition of the car.

Unlike the conventional 1-way remotes where you get no feedback if your given command has been performed, the 2-way systems provide excellent feedback. 

The car owner feedback either in a message notification or light form that the car has been turned on or off, the heating or air conditioning system has been turned on or even the radio activity.

So, your car alarm unit receives information from your remote, and it sends back information to the remote – 2-way car alarm.

5) Two-Way Paging System

With a two-way paging system, you no longer have to depend on just a car alarm sound or light flash to know when your car is being tampered with. It brings the information right to you.

Most of our reviewed automotive alarm & keyless system accessories include LCD modules which ensure that you have better and more illuminated visual feedbacks.

6) Encryptions

Today, car thieves are more sophisticated. Not all depend on the hotwiring or crowbar technique to steal cars. They now employ high-technology hacking systems to evade the digital security your car has in place.

However, you can prevent them from being successful with your car through a automobile alarms systems with high-end encryptions that are very hard to infiltrate.

One of such is the SuperCode encryption which is found in the Clifford 5906x car alarm unit. With such encryptions in place, it will be next to impossible to steal your car.

7) Car Alarm Installation Unit

Installing a car alarm unit is actually not an easy process. You will most likely have to read through manuals, instructions and even watch tutorial videos to know what panels and wiring you need.

This is why it is mostly advised that you purchase car alarm devices that are not too difficult to install or it will affect aftermarket car alarm installation.

If you have no idea whatsoever about fiddling with the wires and electrical system of your car, as it is highly recommended that you seek the services of a certified professional.

However, if you have some knowledge and you desire to DIY, you can do that as you follow instructions. However, car alarm DIY installations may affect the device’s warranty.

8) Remote Starts

Just like keyless entries which enable you to lock and unlock your car from the remote, remote starts are not that much of a security feature.

However, remote starts to add a considerable amount of convenience to your car alarm unit. With a remote start on your unit, you can easily adjust the interior temperature of your car.

You can make it either warm or cool some minutes before you get into your car.

This way if you are coming into your car from cold weather, you can expect to get warm in your car, and if it’s the other way around, you can get cool air in your vehicle.
