Best Blind Spot Detection System For Reliability [Guide] 2022


Our modern cars have been improving every year with new safety features that alert the driver and protect us in accident situations, .e.g., airbags, seat belts, even car seats, and energy absorption technology.

There are many enhancements that we take for granted that help prevents accidents in the first place, .e.g., turn signals, side mirrors, backup cameras. Adaptive cruise control, self-parking, and collision detection systems are beginning to be offered.

Features such as blind spot detection systems exist in many new model vehicles and are being enhanced with new features every year. But older cars lack these safety features, placing the drivers at a disadvantage.

However, car owners of older vehicles are finding aftermarket solutions to enhance their safety, improve reaction time, and prevent accidents. There is a wide range of blind spots monitoring products available to detect vehicles with a variety of features available, including visual and sonar warnings. These systems utilize radar based technology.

Blind Spot Detection Systems Buying Guide

New cars are arriving with all of the latest features. However, older model cars lack of technology such as blindspot detectors. There are newer systems and products available on the market which can be installed professionally as well as by DYI.

Many drivers of older model vehicles can now add these devices to their cars with little expense. There are specifications and capabilities that everyone should consider for their safety.

What to look for in a blind spot detection systems?

Many systems do not work on cars with steel bumpers. Other considerations include ease of installation, range of detection, indicators, false alarms, adjusting sound levels. Most systems include two bumper sensors, while a few offer four sensors to cover all four corners. The following provides a little more detail.

Easy installation and setup

Ease of installation is important whether you intend to install it yourself or hire a professional. Some kits require holes to be drilled and canwire connection to be run, while others require less work using 3m adhesive to secure the sensors and time, which is important for a professional installation. It is important to use waterproof connectors when installing blind spot systems.

Range and detecting distance

Short detection distances very little warning of nearby vehicles in blind spots. Longer distances of up to 50 feet gives ample warning of cars approaching on either side of your car on a multilane highway. When looking for range capability make sure you understand both the side and rear range.

Type of indicator

Systems may include adjustable sound buzzers, LED systems, and even cameras. LED systems have additional indications, especially in situations where there is noise in or around your vehicle. Usually, the indicators are on a round form and they come with 3M adhesive for installation.

Amount of false alarm

Blind spot systems should be evaluated for false alarms caused by your vehicle passing stationary objects at high speeds. Many systems have algorithms to filter out false alarms.

How does a blind spot detection systems work?

How a blind spot detection system works
How a blind spot detection system works.

A blind spot system consists of a control box to manage the signals received from the radar sensors, interpret them and make decisions to trigger either sounds or LED lights to indicate something is in your blindspot. This feature allows for false triggers at times. Better systems will filter out false triggers for your safety.

Different type of blind spot sensor kits

The two main type of blind spot systems is those which are installed by the automotive manufacturers as original equipment and aftermarket systems that can be installed on older vehicles to add safety for their drivers.

OEM systems

Original equipment manufactured is a term given to items that are intended to be offered as standard equipment or upgrades by manufacturers at certain trim levels. Original or OEM blindspot mirror indicators might be available depending on your car model.

Aftermarket blind spot systems

Aftermarket blind spot systems are meant to be added to vehicles of older vintage. This would also include custom-designed kits and underglow kits designed to fit many models after they are driven off the dealer’s lot. Make sure you read the instruction manual prior to the installation.


Can you trust a blind spot device?

This system should be treated as an assist. Some systems will offer many false detections or false triggers, while in specific conditions, some may miss threats from vehicles in your blindspot. Always check rearview mirrors, side mirrors, and look over your shoulder before changing lanes. The range and the blind spot warning system play a crucial role.

Do I have to clean the sensors?

Generally, the sensors do not have to be cleaned. However, if your driving in very dusty, muddy, or icy conditions, the material could build up on the sensor making it less accurate and effective. Even some of the best blind spot detection systems might need some sensor cleaning. Look for a monitoring device design with good detection capabilities, and that does not require constant sensor cleaning.

Wrapping It UP

Blindspot sensor kits can be installed by DYI consumers as well as professionals. They offer a variety of features. e.g., sonar and visual LED warnings, as well as cameras. More sophisticated blindspot detection models will filter out false triggers, ensuring higher accuracy levels. Remember to look for 3m adhesive and adjustable sensors for ease of installation.

Most come with visual indicators. However, they do not provide parallel parking assistance, speed detection, or alerts to cross traffic. Never rely on these detectors 100%, always check mirrors and check over your shoulder before you change lanes. Blindspot mirrors are another cheap and less effective solution for blindspot detection in cars for extra safety.

On our previous aftermarket blind spot monitoring comparison table that you saw up top, you can choose from the top 5 systems on the market. I hope you now know how to choose the best blind spot detection device. Do yourself a favor and get a monitoring product included next time you go out car buying.
