Automotive Night Vision – How Does It Work?


Driving is one of the most common tasks and activities that can only be done outdoors. When you went to your house, you would see many cars that are being driven. But it can also be observed that many accidents happen these days, especially during nighttime when the road does not have good lighting conditions. That’s why there are safety devices used for the automotive industry and continuously manufactured as the demand increases. 

Mostly, this type of safety device is installed to prevent a lot of accidents. With many cars present and reckless drivers that you may encounter on the road during nighttime, safety precautions and measures must be installed and incorporated in cars these days.

Automotive Night Vision

Automotive night vision is a device that is usually installed in cars for the drivers to have a guide once they drive at night and in some other dark places. With the use of automotive night vision devices, drivers would be able to navigate easier through locations that are considered very low in light. 

When there is no automotive night vision device installed in a car, the only way drivers see the darkness is through their headlights. But once two vehicles meet on the road in total darkness, they both tend to use their headlights. With that happening, the amount of glare brought by two headlights coming across each other may cause some accidents, especially when the drivers get temporarily blinded by the glare. 

So, the best option that drivers these days can do is equip their cars with an automotive night vision device or system that can help them see better and easier at night. Actually, there are a lot of devices that drivers can choose from. Some of these are infrared light, thermal cameras, night vision display, and many other more. 

How Do Automotive Night Vision Devices Work?

Working process of Automotive Night Vision Devices

Since the installation of automotive night vision systems in cars has been beneficial as drivers try to navigate the roads at night, manufacturers have many designs for these devices. Two of the most common types known by people are the passive and active system—these two are the most useful classifications of automotive night vision devices. With that said, here is a simple yet detailed explanation of how these two types work.

The Active Type System

The first type of automotive night vision device is the active system. This type needs infrared light for it to function properly. One of the primary and main components needed for this type to see through the dark is the infrared light emitted by cars, as mentioned above. Even in very low light areas, this is a better choice when compared to using headlights. 

Since infrared lights are known to have one of the shortest wavelengths, they are not really visible to the human eye. With that said, they do not cause glare production even when there is a large amount of it. This type is really helpful in preventing accidents that are caused by temporary blindness from seeing too much glare from very bright headlights. This type of automotive night vision device is further classified into two sub-types—the gated systems and the non-gate systems.

The Passive Type System

The second type of night vision for automotive is the passive system. Unlike the first type, this one does not need the use of infrared lights. It uses thermographic cameras to capture thermal radiations emitted by cars and other types of vehicles. All vehicles emit some thermal radiation since they are machines that get heated when used. This type is more reliable for driving in darker places; that is why it is truly beneficial for many drivers. One of the main advantages of having a passive type is that this type also has a wider range when compared to the first one.

Does Having an Automotive Night Vision System Help in Reducing Accidents?

It can be seen that the use of the automotive night vision system can really be of extreme help to reduce the number of accidents that are related to cars. Studies and data have shown that most accidents happen at night, where the lighting is very critical. Through the use of automotive night vision systems, even objects and other cars at a distance of 500 feet away can be detected and seen right away. Through all the functions of this night vision system can be reduced accidents at night.

Benefits of Having an Automotive Night Vision Device System

The benefits of having a night vision system for your cars is really evident. Besides being prepared and ready to prevent accidents, it can also help drivers be responsible while driving. But the use of such devices must be utilized appropriately to see and enjoy the benefits they bring. With the number of accidents happening these days, it is beneficial to prevent them from happening to you and to other cars that you might encounter on the road. With these types of systems, you would be able to save lives in just a very simple way.


As you know, accidents may cause injury, and safety must be one of your biggest priorities. So, when you prevent accidents, you would also be able to prevent injuries from happening. In addition, your life would not be at risk. Life is true of paramount importance; that is why it is required to be prepared with safety precautions to protect it. With that said, you must consider having an automotive night vision system in your car.
