One of its standout aspects is the two-way remote control, which allows you to receive feedback from the alarm, ensuring you know its status at a glance. The noise level of 125 dB is impressive, making it quite loud and likely to deter potential thieves. Its compatibility with Viper SmartStart also means you can control the system via your smartphone, providing added convenience.

Installation is a crucial factor, and Viper alarms usually require professional installation, which could entail additional costs.

This product is particularly suitable for individuals looking for enhanced security features for their vehicle, especially those who appreciate smartphone connectivity and robust alarm noise. However, if you're someone who favors ease of installation and straightforward usage, it may require some consideration before purchasing.

The CS2WQ900AS from Sound of Tri-State is a car alarm and remote start system designed for cars, trucks, and motorcycles. It offers a solid remote range of up to 3,000 feet, allowing you to start your vehicle or control the alarm from a significant distance, which is convenient for colder or hot days. It includes two-way communication, enabling you to receive alerts or confirmations directly on the remote control. The package includes a GPS add-on module for extra security and a Blade-AL bypass module to help the remote start system work with many vehicles’ existing security systems.

Both modules require professional installation and programming, which can add to the overall cost and effort, especially since the product does not include installation instructions. The system is compatible with a wide range of vehicles, but due to its complexity, it is best suited for users who have access to professional car electronics services. The product has a strong customer rating of 4.5 out of 5, indicating that users appreciate its performance and features.

While the system covers important aspects such as security, remote start, and extended range, the necessity for expert installation and the lack of user-friendly setup guidance might be a drawback for those seeking a simple DIY solution. The warranty is limited to one year, which is fairly standard and should be considered when making a purchase decision.

The Compustar CS7900-AS is a solid choice for those looking for a comprehensive car alarm system with remote start capabilities. Its standout feature is the impressive 3000-foot range, allowing you to start or secure your vehicle from a considerable distance, which is particularly beneficial in large parking lots or when you're not right next to your car. The system comes with a 2-way interactive remote, providing visual and audible feedback, so you're always aware that your commands have been received. This is an excellent feature for anyone who values reassurance in car security.

In terms of security, the CS7900-AS is equipped with intelligent sensors that can detect intrusions through door, hood, and trunk sensors, as well as impact sensors. This broad range of detection means you can customize the level of protection based on your needs, providing peace of mind when leaving your vehicle unattended.

However, there are some drawbacks to consider. The system requires professional installation, which can add to the cost and time needed before you're fully set up. Additionally, some vehicles might need extra parts that are not included in the package, potentially leading to further expenses or delays. The lack of installation instructions and wiring diagrams may feel daunting for those who prefer a DIY approach.
