The first and foremost decision that you have to make is about the sensors. The sensors are the entire system.

We will talk about the activation method in a while. Before that, let us talk about why these are important.

The sensors detect the car to alert the driver. Now there are different kinds of sensors. They may be automatic, or they may need a startup system with the engine. Some also start working at a certain speed.

  • Self-sensing: Self-sensing blind spot detection systems come in a series of prices. However, since there is a motion sensor, the best usually comes at a higher place. These sensors blink and make noise only when they sense a motion passing by. These are very accurate since they do not own sense standstill cars.
  • Turn signals: Turn signals are nothing new. They are very effective and also very reasonable. They are universal OEM, and they also come in the original make for all kinds of vehicles.
  • Speed detection: Another very common sensor is when the car is at a certain speed or higher. Since there is not much to do on the driver’s end, drivers prefer it. However, it is not suitable for smaller cities with a lot of traffic as you may not be able to reach the speed.
  • Start with the engine: As the engine starts, these sensors activate and keep running. It takes a lot of your car’s battery and may be confusing to everyone on the road. However, it is cheap and very effective.


Another very important factor is the range. Not the price range, but the detection range. The detection range is as important as the sensors are. The reason is that they work to tell you about the hazard that approaches you.

But what is the right range?

Well, the right range is dependent on your driving situation.

If you like to drive on highways and are using your vehicle for that, then a great range is what you need. However, keep in mind that the bigger and stronger the sensor, the more it shall cause.

For regular city traffic roads, you will not need a very strong sensor. Then you can listen to your pocket and get the one that suits you the best.


The input for the detection system is cars and hazards. But what about the outputs!

Read on because this is very interesting! The output is of two basic types.

The audio output: In this output, the sensors make some sort of buzz or sound to alert you. Want to know something fun? These sounds are customizable as well. It means that you sensor can have someone scream too. But choose wisely!

The visual: The visual is not limited. Let us talk about the different types of visual outputs.

  • Video: Some detection systems depend on a camera. The screen is inside the car, and you may view several angles on it at once.
  • Lights: lights are the most common detection systems. However, when you select lights, you have to keep something important in mind. Make sure that they are day and night lights for the perfect vision even in the brightest days.


More people die of car accidents every year than any disease. A big part of these accidents is because road safety has the potential of getting more advances. Even if it is gone far, people generally avoid it because they think they are immune.

We highly believe it is important for you to get the best blind spot detection systems for your car. It is a small nuisance which may turn out to save you and your loved ones’ life!
