How to Choose a Blind Spot Monitoring Kit: Buyer’s Guide

When researching and choosing the best blind spot monitoring kit for your car, several key factors deserve careful consideration:

Sensor type: Radar, ultrasonic, or camera-based systems each have their strengths and weaknesses. 

Radar offers excellent long-range detection, ultrasonic is budget-friendly but less accurate, and camera systems provide visual confirmation but might have limited visibility in certain conditions. 

Consider your priorities and driving environment. Choose a kit with sensors suitable for your driving needs and environmental conditions.

Detection range: This determines how far away the system can identify vehicles in your blind spot. A larger range offers more time to react but might come at a higher cost. 

Choose a range that suits your typical driving speeds and scenarios. Evaluate the coverage area and range of the BSM system to make sure it effectively monitors blind spots and provides timely alerts.

Detection accuracy: False alarms can be distracting and annoying. Look for a system with a good reputation for accurate detection to avoid unnecessary alerts.

 A BSM kit that offers reliability and accuracy in detecting vehicles in blind spots minimizes false positives or negatives effectively.

Alert type: Consider the type of warning system the kit employs, such as visual indicators (LED lights), audible alerts (chimes or beeps), vibrating steering wheel feedback, or a combination, that can each be effective.

Choose one that suits your preferences, driving habits, and needs.

Customizability: Some systems allow you to adjust the sensitivity of the sensors, the volume of the alarms, the brightness of the LED indicators or even customize the system to better suit individual driving preferences. 

Consider kits that allow users to adjust settings that can be helpful for tailoring the system to your specific needs.

Additional features: Though not completely necessary, look for advanced features like rear cross-traffic alert, lane departure warning, or blind spot camera view if you desire increased driving safety and awareness.

Ease of installation: This is very important. Assess the complexity of installation. Some kits are designed for DIY installation, while others require professional assistance. Consider your technical skills and comfort level when making your choice.

Compatibility: Ensure the system is compatible with your specific car’s make and model. Some kits require additional wiring or adaptors for integration.

If your vehicle has existing safety features, check if the BSM kit can seamlessly integrate with them, enhancing overall safety capabilities.

Warranty and Support: Blind spot systems are technical in nature. Choose a kit from a reputable manufacturer that offers a warranty and provides good customer support, ensuring assistance in case of any issues.

Price: Blind spot monitoring kits can range from budget-friendly options to high-end systems with advanced features. Set a realistic budget and prioritize the features most important to you.

Installing Blind Spot Monitoring System Appropriately

Installing a DIY blind spot monitoring system can seem daunting, but it’s often more straightforward than you might think.

However, specific steps vary depending on the system you choose. Here’s a general outline of the process with some key considerations:


Thoroughly study the instructions provided with your specific system. Each brand and model may have unique installation procedures.

Identify suitable mounting points for the sensors and indicators. Ideally, sensors should be placed on the rear bumper, facing backward slightly to cover your blind zones effectively. Choose locations with a clear view and avoid obstructions like exhaust pipes or license plates.

You’ll likely need basic tools like screwdrivers, pliers, a drill, measuring tape, and electrical tape. Consult your system’s manual for any specific tools required.

Installation Steps

  • Follow the instructions to secure the sensors in the chosen locations. Some systems use adhesive mounts, while others require drilling. Ensure the sensors are level and securely fastened.
  • Most DIY systems use pre-wired harnesses for easy connection. Consult the manual for specific wiring instructions related to your system and vehicle.
  • Route the wires from the sensors to the control unit or display, keeping them concealed and protected from wear and tear. Some systems might require connecting to your brake lights or other power sources.
  • Place the LED indicators or displays (usually near the side mirrors) according to the manufacturer’s recommendations. Ensure they are visible and unobtrusive but won’t interfere with your driving.
  • Once everything is connected, follow the instructions to test the system’s functionality. Check if the sensors detect objects correctly and trigger the intended alerts (visual, audible, etc.). Make adjustments if necessary.

Remember, the specific installation steps can vary significantly depending on your chosen system.

Always prioritize safety and follow the manufacturer’s instructions carefully to ensure a successful and functional blind spot monitoring system.

Are Blind Spot Monitoring Systems worth it?

Blind spot monitoring systems can significantly improve driving safety by alerting you to vehicles in your blind zones that you might miss visually.

Studies have shown they can reduce lane change accidents by up to 50%. While not a substitute for safe driving practices and vigilant observation, they can be a valuable safety tool, especially for drivers with larger vehicles or those who frequently navigate busy roads.

What Are the Different Types of Blind Spot Monitoring Systems?

Two main types of blind spot monitoring systems exist: sensor-based and camera-based.

Sensor-based systems typically use radar or ultrasonic sensors to detect objects in your blind zones. They are generally more affordable but may have limitations in certain conditions like bad weather.

Camera-based systems use wide-angle cameras to provide a visual display of your blind zones, potentially offering more information but often at a higher cost.

Can You Install a Blind Spot Monitoring System Yourself?

Some DIY-friendly blind spot monitoring systems are available, typically using adhesive mounts and pre-wired harnesses for easier installation.

However, the complexity can vary depending on the chosen system and vehicle compatibility.

If you’re not comfortable with electrical work or modifications, professional installation is recommended to ensure proper functioning and avoid potential issues.

Do Blind Spot Monitoring Systems Have Any Disadvantages?

While valuable, blind spot monitoring systems are not perfect. False alarms can occur in certain situations like heavy rain or snow, leading to potential distraction.

Additionally, they should not be solely relied upon as they may not detect motorcycles, bicycles, or smaller objects.

Remember, they are an additional safety tool, not a replacement for careful driving habits and visual checks.

How Much Does it Cost to Add Blind Spot Monitoring to a Car?

The cost of a blind spot monitoring system can vary considerably depending on several factors such as type, brand, features, compatibility, etc.

Sensor-based BSMs are typically more affordable, ranging from $150 to $300 for DIY kits to $500-$800 for professionally installed systems.

If the blind spot monitoring system is camera-based it can be more expensive. The cost may start around $500 for basic options and reach $1,500 or more for advanced systems with additional features like lane departure warning.

Premium brands and systems with multiple features like rear cross-traffic alerts or blind spot camera views will naturally cost more than basic models.

DIY installation is usually free, but professional installation can add costs ranging from $100 to $200 for simple systems to $300 or more for complex integrations.

Some systems require additional parts or adaptations for specific car models, potentially increasing the overall cost.

It is important to consider your needs, driving habits, and desired features to find the best value for your money. Make sure to research multiple options and compare prices before making a purchase.
