#1 Avital 3100LX
If you don’t have much money to spend on a car alarm but still need some extra protection for your vehicle, check out the Avital 3100LX. This well-priced system offers good basic protection, including engine immobilization, and is simple enough for many people to install themselves. It hooks up to the vehicle’s existing horn so there’s no need to find room for or mount a separate siren.
The Avital 3100LX comes with a pair of remotes and supports up to four. As well as the alarm itself, this is a great — and low-cost — way to add keyless entry, trunk release, and remote starting features to an older vehicle.
If you can’t find your vehicle in the parking lot or if you see someone paying it a little too much attention, there’s also a panic mode that sounds the horn and flashes the lights.
If you’re unsure of what to look for, knowing how car alarm sensors work may help to inform your shopping decision.
#2 Python 5760P
Python car alarm systems fall somewhere between budget brands like Avital and luxury labels like Viper, offering an impressive array of features for a reasonable sticker price. With a one-mile range, Python 5706P easily outperforms other alarm systems in the same price bracket without sacrificing details like remote start and an LCD remote. This system also has multiple inputs for expansions and a long battery life in comparison to other car alarm systems. Built-in shock sensors and an array of other sensors you can customize for sensitivity make Python more than just a loud siren to scare away would-be car thieves.
Like any product, Python does come with some faults. Two standouts are the higher cost of the system compared to similar systems and the hassle of installation, which should be done by a professional to comply with the warranty terms. While it does have smartphone capabilities, they aren’t fully integrated and require purchasing additional modules.
#3 Omega K9 Mundial-4
Despite its low price, the Omega K9 Mundial-4 is full of useful features. This alarm system includes a dual-zone shock sensor, loud electronic alarm, keyless remote entry, trunk release, and two panic alarm options. The system also includes a separate anti-carjacking function, which can be configured to activate when the vehicle is started, if the doors open or close while the ignition is on, or via the remote.
Nice and loud by default, the volume of both the alarm and the confirmation chirps is configurable, along with a range of other settings from automatic arming to open door alerts. The included remotes are unusually stylish for an inexpensive system like this, with four separate control buttons.
If the inbuilt security features aren’t enough for peace of mind, the Mundial-4 also has auxiliary inputs for adding proximity sensors and more.
#4 Viper 5906V
If you’re looking for the Cadillac of aftermarket car alarm systems, Viper should be your first stop. The company has an industry reputation for offering the best car alarm systems available, but those extra features come with a price tag to match. Viper has invested in the latest security like advanced encryption, customized sensors, and multiple kill switches, and it fully integrates with your smartphone. True to Viper’s reputation for excellence, the color OLED display in the remotes is unlike anything you’ll find in other systems, and the one-mile range places the company at the top.
The Viper 5906V is not, however, the kind of car alarm system you can install yourself. You’ll need to visit a certified dealer or run the risk of invalidating your warranty. Of course, the Viper’s cost can be prohibitively expensive for many car owners and is probably most attractive to those who have a ride that’s worth the extra protection.
#5 Compustar CS7900
Compustar has done a very nice job putting this car alarm package together. It offers those who install it a wide variety of security and other useful functions. It all starts with its car alarm system that includes a remote starting capability. Other security features in the package include a dual-stage shock sensor and a loud electronic siren.
One of the best features you get with this car alarm package is its two-way remote. It acknowledges your commands both visually and audibly. The remote has a very generous 3000 feet working range too. There is also a backup 1-way remote and optional door, hood, and trunk impact sensors can be added.
#6 Crimestopper SP-502
Avital is another brand owned by Directed Electronics.
Avital makes solid security gear and has been around for nearly 20 years. I have personally used Avital alarms in my vehicles and can attest to the quality of their products.
The Avital 5305L is an excellent mid-tier security system with plenty of features that will keep your vehicle secure without breaking the piggy bank.
