Blind Spot Detection System Buying Guide

New cars are arriving with all of the latest features. However, older model cars lack features such as blind spot detection. There are many 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 features and capabilities that everyone should consider.

What to look for in a blind spot system

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 provide little warning of nearby vehicles in blind spots. Longer distances of up to 50 feet provide 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 audible sound buzzers, LED systems, and even cameras. LED systems provide additional indications, especially in situations where there is noise in or around your vehicle. Usually, the warning 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 system 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 audible sounds or LED lights to indicate something is in your blind spot. This feature allows for false triggers at times. Better systems will filter out false triggers.

Different type of systems

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 cars to provide added 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 blind spot mirror indicators might be available depending on your car model.

Aftermarket Systems

Aftermarket 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.

F.A.Q

Can you trust a blind spot system?

A blind spot 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 blind spot. Always check rearview mirrors, side mirrors, and look over your shoulder before changing lanes. The range and the blind spot warning sensor 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. Some aftermarket blind spot detection systems might need some sensor cleaning. Look for a monitoring system design with good detection capabilities, and that does not require constant sensor cleaning.

Wrapping It UP

Blind spot sensor kits can be installed by DYI consumers as well as professionals. They offer a variety of features. e.g., audible 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 audible and visual indicators. However, they do not provide parallel parking assistance, speed detection, or alerts to cross traffic. Never rely on blind spot detectors 100%, always check mirrors and check over your shoulder before making a lane change. Blind spot mirrors are another cheap and less effective solution for blind spot detection in cars.

On our previous blind spot detection systems comparison table that you saw up top, you can choose from the top 5 systems on the market. We recommend reading our best car seats for the infant’s  or babies review. I hope you now know how to choose an aftermarket blind spot monitoring system. Do yourself a favor and get a monitoring system included next time you go out car buying.
