Blind Spot Detection System Buying Guide
Car accidents are a daily occurrence especially during traffic jams and severe weather conditions. Everyone from beginners to seasoned and diligent drivers can get involved in rear end collisions, and this is why blind spots are not to be underestimated. Even people with sharp senses and decades of driving experience under their belt need to check their rear-view mirrors before changing lanes. Blind spot awareness is incredibly important and so is investing in the right detection system. The following guide showcases the different types of detection systems and how they can make a difference when it comes to car safety.
What to Look for in a Blind Spot Detection System
- Detection Range
Sensors are an integral part of any blind spot detection system and they are typically sold in pairs or as a full set for both front and rear bumpers. They rely on sonar or high frequency radio waves that detect vehicles and other obstacles that end up in the blind spot. These sensors are connected to audio and visual indicators that send instant warnings to the driver when changing lanes. These warnings typically work when the turn signal is switched on and they come in the form of buzzers and LED lights that were designed to grab the driver’s attention. Side view cameras are also available as an alternative to car blind spot sensors and those are mounted on the mirrors. These cameras are typically connected to an HD monitor that is mounted on the dashboard. Not all sensors have the same detection range, so car owners need to take this into consideration when shopping for a new system.
- Adjustable Indicators
As discussed above, sensors have to be connected to an indicator in order to convey their message to the driver. These indicators are installed inside the vehicle and give off audible sounds and lights that are hard to ignore. Most buzzers can be mounted anywhere, and their volume can be easily adjusted, while LED indicators can be installed on the dash or instrument cluster. Some systems allow you to customize their settings so they either work non-stop or only when needed.
- Fewer False Alarms
There are several car accessories that can prevent the system from delivering accurate results. Bike racks and spare tires can be mistaken as hazards, resulting in false alarms. This is why it is important to invest in a blind spot detection system that is able to recognize these items for what they are. Some detection systems are equipped with smart technology that allows them to recognize mounted items and label them as non-threatening. This allows the system to focus on actual road obstacles and other vehicles.
- No-Fuss Installation
Some car owners prefer to personally install any new gadget or accessory using their own tools and with the help of the instruction manual. Some manufacturers sell installation kits with each individual system to make this process easier and less time consuming. Some systems take up more time than others and may require professional help while others are simple and straightforward come installation time.
Why You Should Use an Aftermarket Blind Spot Monitor
According to the Insurance Institute for Highway safety, aftermarket blind spot detection systems were responsible for reducing injuries related to lane change accidents by 23%, saving lives in the process. This technology is on the rise, and for good reason. The National Highway Traffic Safety Administration has also stated that getting rid of the dangerous blind spot behind vehicles can prevent more than 80,000 injuries and more than 100 deaths per year. These numbers alone should encourage car owners to invest in this system in order to double down on their safety while driving.
- More Eyes on the Road
Sensors were meant to provide assistance and an extra pair of eyes where it matters. Blind spots are extremely dangerous especially on the highway where high speeds can lead to fatal car crashes. Installing two or even four sensors allows you to worry less about changing lanes and focus more on the road ahead. Side-view cameras can also assist newbie drivers with parallel parking and changing lanes in high traffic areas and neighborhoods.
- Audio and Visual Warnings
Both audio and visual warnings give drivers the time to recalibrate and re-asses the situation. Sometimes, changing lanes can be a challenge and failing to notice a car in your blind spot can be disastrous. Even the most experienced drivers can end up making the worst decisions while driving due to stress or a lack of sleep. Installing this system is like having your very own parking and lane assistant who will help you make a more informed decision.
- Doubling Down on Safety
There is no such thing as too much safety when it comes to driving and this is evident in the increasing number of safety features found in modern cars. Automotive companies have everything covered from shatter-resistant glass to traction control. Blind spot detection systems are no longer reserved for modern cars. Proud owners of classic cars or even older models can buy their peace of mind by installing this system in their respective vehicles for an additional layer of security while driving.
Types of Blind Spot Detection Systems
- Aftermarket Systems
There are so many accessories and replacement parts that fall under the aftermarket umbrella. These accessories and gadgets allow car owners to modernize their old cars without breaking the bank. Upgrading your cars overall safety is now possible thanks to blind spot sensor kits. Some of these kits offer the same performance and finish as factory-installed ones. Others have a universal design that works with different makes and models.
- OEM Systems
Original Equipment Manufacturer systems are model-specific, and factory installed so they offer a higher degree of accuracy and performance. These systems vary depending on the brand, but most luxurious cars have sophisticated blind spot detection technology. For example, the Infiniti M-Series goes one step further with its blind spot intervention system. This system prevents the driver from changing lanes if he or she ignored the audible and visual warnings. OEM systems can be upgraded to include more accurate sensors and waterproof cameras that can withstand rain and snow.
Best Blind Spot Detection System FAQ:
Q: How does blind spot system work?
Blind spot systems rely on ultrasonic or radar technology to keep an eye on the blind spot region of the vehicle. Once a moving object be it a car or a person is detected within this area, a warning signal is triggered. This technology involves sensors or side-view cameras that are mounted on the sides of the vehicle or near the rear-view mirrors.
Q: Is blind spot monitoring reliable?
Reliability depends on the accuracy of each individual system and its false alarm rate. Some systems are more reliable than others.
Q: How do I clean a blind spot sensor?
Sensors are mounted in areas that are prone to road grime, therefore cleaning them on a regular basis is a must especially during winter. The cleaning process is simple and easy. All you need is a bucket filled with water, a small amount of soap and a non-abrasive cloth. Use the cloth to gently wipe the sensors clean.
