Automotive safety technology has come on leaps and bounds in the last 15 years. Most newer cars now come equipped with blind spot detection systems, which let the driver know of any potential danger in spots they can’t easily see using standard mirrors.

Back in the day, this technology simply wasn’t available for older vehicles. If you want to improve your road safety, investing in an aftermarket blind spot detection system is one of the best purchases you can make.

In this review, we’re going to take a look at five of the best blind spot detection systems on the market to help you make accidents and near misses, a thing of the past. But before we get to them, our buyer’s guide will break down why it’s so important to have a system in place and what features to look for when making your purchase. So let’s go through it…

Blind Spot Detection System Buying Guide

It doesn’t matter whether you have decades of experience behind the wheel or are a complete novice, blind spots are a danger to all road users if you don’t have a detection system in place.

Increased Awareness

You can only monitor so much with your eyes and mirrors. A blind spot detection system is like having an extra pair of eyes dedicated to avoiding collisions.

Improved Reaction Time

To react to something quickly, you need to know it is there in the first place. That extra reaction time could potentially save your life in a high-speed situation.

Passenger Safety

Passengers will automatically feel safer in a car protected by a blind spot detection system. They will also be aware of any warning indicators, effectively providing another level of security in case the driver misses something.

Detection Range

Sensors are the most important component of any blind spot detection system and are mounted on the front and rear bumpers. They use radar to detect any unseen vehicles or obstacles in your blind spot and let you know of the imminent threat through an audio or visual indicator mounted inside the car.

Alternative systems use side view cameras mounted on wing mirrors to do the same job. These are usually connected to a tablet display that is mounted on the dash. Blindspot detection ranges vary between products, so look for systems with as long a range as possible.

Adjustable Indicators

Choose a system that allows you to adjust warning indicators to your preference. Most buzzers can be adjusted easily for volume. Place any visual system in a spot where you’re going to see it. Most systems can be customized, so they either work all the time or only in circumstances where you want them to.

Installation

Aftermarket systems are designed to be compatible with most passenger vehicles. You should only consider installing the system yourself if you know what you are doing regarding wiring and bumper removal. Most people will find it easier to have the system professionally installed.

Now we know a little more, let’s take aBest Blind Spot Detection Systems look at five of the best aftermarket systems currently available, starting with a quick comparison.

Top 5 Best Blind Spot Detection Systems To Buy – 2020 Reviews

1 Greenyi Blind Spot Detection HD Camera

The cheapest model on our list, the GreenYi, has a high definition camera with motion sensors to monitor blind spots. It relays the imagery to a 5-inch monitor, which can be easily attached to either the dashboard or the windshield. Two LED indicators on the camera provide the warning system and can be adjusted for brightness easily.

The HD camera comes equipped with night vision capabilities of up to 16 feet, so whether it’s night or day, you’ll be able to change lanes or parallel park safely. On the downside, the camera isn’t waterproof, so you’ll have to install it in a protected spot under the wing mirror.

Plenty of cabling…

Installation of the camera and the monitor is straightforward, although it might be wise to get a professional to help with the wiring if you’re not confident. Twenty-three feet of cabling means this system will fit larger vehicles too.

All in all, a cheap system that will provide increased safety without the comprehensive coverage that other models provide.

Greenyi Blind Spot Detection HD Camera
Our rating:3.5 out of 5 stars (3.5 / 5)

Pros

  • Very affordable.
  • Easy installation.
  • Warranty of 1 year.

Cons

  • Camera should be waterproof.
  • LED indicator lights can be annoying.

2 Audiovox Psd100 Blind Spot Detection System

Also, at the lower end of the price scale is the Audiovox PSD100. This is purely a sensor-based system with no cameras utilized. Two rear-mounted sensors will detect anything within 6 feet of your bumper. This really isn’t an adequate distance when driving on fast-paced highways but will certainly help with those that struggle with their parallel parking.

Extra sensors can also be purchased if you want to add a couple to the front bumper too. Warning indicators come in the shape of a buzzer and LED lights, the volume, and brightness of which are both adjustable.

Won’t forget…

The Audiovox also provides a flash memory feature. This allows the sensors to identify and remember any accessories attached to your vehicle, for example, a bike rack. These can often lead to false warnings and trigger alarms, so it’s a big plus that this issue has been dealt with.

In summary, the Audiovox is an effective system for parking or moving in slow traffic, which doesn’t really provide the kind of protection needed when changing lanes at higher speeds.

Audiovox Psd100 Blind Spot Detection System
Our rating:3.8 out of 5 stars (3.8 / 5)

Pros

  • Low price point.
  • Effective at slow speeds.

Cons

  • Low detection range.
  • Not very effective in high-speed situations.

3 Accele Bss200 Blind Spot Sensor Kit

This mid-priced detection system from Accele is a sensor-based system that will provide a decent level of protection without intricate installation and setup.

The two sensors are mounted on either side of your rear bumper, enabling blind spot detection on both sides of your vehicle. Once installed, they have a paintable surface, so can be painted to match the color of your bumper for a less conspicuous look.

Quick as a flash…

Audio and visual indicators are provided via a small speaker and LED lights that have adjustable levels. The audio warning is turned on when your turn signal is activated. If a vehicle is approaching, or in your blind spot, then you’ll receive an instant sound alert the moment you signal. This can be configured to work at all times if you prefer.

The detection range of 14 feet whilst not world-beating, is a significant improvement on the 6 feet offered by the Audiovox. However, one criticism would be that the sensors are occasionally guilty of sending false warnings.

If you are opting for a lower-priced system, we’d recommend the Accele over the Audiovox every time due to the increased detection range. However, there’s another cheap option that is better than both.

Accele Bss200 Blind Spot Sensor Kit
Our rating:3.2 out of 5 stars (3.2 / 5)

Pros

  • Turn signal activation.
  • Suitable for parking and lane changing.
  • Easy to install.
  • Paintable bumper sensors.

Cons

  • Occasional false detections.

4 Carbest Ultrasonic Blind Spot Detection System

If you’re looking for the best budget option, then look no further than the CarBest Ultrasonic detection system. Utilizing the same sensor-based system as the Auidivox and Accele systems, it has a number of technological advantages over its competitors.

Firstly, and most importantly, it has a far longer detection range of 49 feet, which simply put, makes highway driving a far safer undertaking. It also has the ability to detect up to five different objects around your vehicle at the same time.

Wide coverage…

The adjustable sensors have an 80-degree detection angle, so with correct placement, you’ll be able to cover a wide area around the rear of your vehicle. And adjustable buzzers and LED lights provide the warning indicators. The buzzers will only go off when the turn signal is activated.

Installation can be done without assistance, and CarBest provides detailed installation instructions if you choose to do it yourself. The sensors are also paintable, allowing them to seamlessly blend with your bumper.

A good package overall and the best blind spot detection system available for under $100.

Carbest Ultrasonic Blind Spot Detection System
Our rating:4 out of 5 stars (4 / 5)

Pros

  • Excellent value for money.
  • Long detection range.
  • High-speed radar detection.

Cons

  • None at this price.

5 Brandmotion Rdbs-1500 Radar Blind Spot System

Brandmotion has created a detection system that is as near as possible to the quality you’d expect from a factory-installed system. It’s also six times more expensive than the CarBest option.

Can it justify the extra expense?

It utilizes a can-wire connection, which means the sensors are only activated when the car is traveling over 15mph. It, therefore, won’t constantly flash in car-parks or other congested areas. This is a bonus for most drivers, although there are some that would consider this to be a disadvantage.

Detection range is a solid 40 feet behind your vehicle, and Brandmotion claims to have eliminated up to 95% of false detection instances. Anything from a motorbike to large semi-trucks will be picked up, no problem. The usual audio and visual warning indicators are present and correct with the audio-only activated when the turn signal is on.

Versatile and compatible…

Installation should probably be done by a professional, but when completed, it fits almost any post-2007 vehicle perfectly. This compatibility is really what you are paying for.

With the lack of false detections and extensive coverage at the front and rear, it probably is the best aftermarket blind spot detection system you can buy. The problem is that it’s only marginally better than the much cheaper Carbest Ultrasonic.

Brandmotion Rdbs-1500 Radar Blind Spot System
Our rating:5 out of 5 stars (5 / 5)

Pros

  • Good detection range.
  • Will fit almost all modern vehicles.
  • Minimal false detection.

Cons

  • Expensive in comparison.

CarBest Ultrasonic

It may not have the sleek finish of the Brandmotion, but it’s detection capabilities are virtually as good, and that’s the most important factor under consideration here. A significant amount of cash will also be saved. It’s a no-brainer, really.
