Some of the best automobile alarm systems on the market include the Viper VSS5000, Python PS5000, Avital 5303L and ScyTek Galaxy G5.2W, according to CarAudioNow.com. Each of these systems places sensors around the car to alert owners in the case of a door opening, window breaking, paint being damaged or tire jacking.
CarAudioNow.com names the Viper VSS5000 as the best automobile alarm system it has reviewed, as of 2015. The Viper VSS5000 utilizes the newest software and technology to incorporate all of the features and sensors of its alarm into an intuitive, easy-to-use application that owners can interact with via smartphone. In addition to improved security features, such as dual-shock sensors, the Viper VSS5000 can also open a car's trunk, remotely start the car and serve as a keyless entry system.
The Python PS5000 is also a well-reviewed automobile alarm system. Just like with the Viper VSS5000, the Python PS5000 has many features that can be utilized from a smartphone, and owners can use their smartphones to connect to their vehicles from anywhere in the U.S. The Avital 5303L represents a great value, costing significantly less than the Viper VSS5000 or Python PS5000, but it does not feature a smartphone app. Instead, owners must use an LCD remote to take advantage of features such as keyless entry, remote start and trunk release.
