Automotive Night Vision – How Does It Work?

Driving is one of the most common activities done outdoors. As the technology grows, the range of vehicles from motorcycles to cars is being increased. The legal studies show that increasing amounts of cars on the roads eventually increase the accident rates, especially at the night.

In most cases, not having sufficient lighting or visibility of the road is the major cause of accidents. To sort out this issue, many major automotive industries were involved in changing nighttime driving safer with their technologies.

Automotive Night vision devices are one of the successful techniques that significantly reduced the rate of road accidents.

Automotive Night Vision

Automotive night vision is basically a night vision camera that is usually installed in cars for the drivers to have a clear view at night and in extremely dark places. With the use of automotive night vision devices, drivers would be able to navigate easier through locations where the lighting conditions are poor. 

When there is no automotive night vision device installed in a car, the only way drivers see the darkness is through their headlights. But when 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 may affect each other and cause 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 for night vision as infrared light, thermal cameras, night vision display, and a few others. 

How Do Automotive Night Vision Devices Work?

Working process of Automotive Night Vision Devices

The installation of automotive night vision systems in cars is beneficial when drivers try to navigate the roads at night.

Two of the most common types of automotive night vision systems are passive and active systems. With that said, here is a detailed explanation of how these two types work.

The Active Automotive Night Vision 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 emitted infrared light. In very low light areas, using infrared light is safer than headlights. 

Since infrared lights are known to have one of the shortest wavelengths, they are not really visible to the naked human eye. With that said, the chance of glare is nill.

It is the best replacement for the bright headlights that create temporary blindness in the drivers and avoids accidents. Active automotive night vision device is further classified further into two 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 thermodynamics to capture thermal radiations emitted by cars and other types of vehicles.

Not only living, but some of the non-living objects also emit heat radiation in certain cases. For example, the vehicles emit thermal radiation when the machines in them get heated while using. This emitted radiation is detected and pictured by the thermal imaging camera.

So, when a car or any vehicle comes across the road, the thermal automotive system in your car detects its heat signatures and draws the picture in your system. By this, you will know there is a vehicle is coming your way.

The main advantage of the passive automotive night vision systems is their wide range of detection.

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 car accidents.

We already know that most critical lighting conditions are the main cause of road accidents. Both active and passive automotive night vision systems detect cars and other objects at a distance of up to 500 feet.

Benefits of Having an Automotive Night Vision Device System

The benefits of having a night vision system for your cars are 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 get the full benefits they bring.

With the number of accidents happening these days and having a solution to prevent this, we should consider using an automotive system in cars. With these types of systems, you would be able to save lives in just a very simple way.


As you know, road safety is a must thing for drivers. If we have prevention and device to stop something bad from happening, why don’t we consider using them?

You save not only yours but many other lives from accidents. Life is true of paramount importance; that is why it is required to be prepared with safety precautions to keep it. 

Next time when you hit the road, make sure you have all the safety measures and devices.
