Automobiles are beginning to get more luxurious due to the fact that people spend most of their time on roads. To improve the quality of driving and to have a better vision of the road, particularly during darkness cars are being equipped with sensors, cameras and high tech systems. The upgraded night vision systems (NVS) within the cars are considered as safe driving assistance during the late-night trips.
Basically, these systems work by capturing infrared lights emitted by certain objects and the end product appears on the car's display. They have the ability to illuminate the routes beyond the reach of the headlights and warn the driver about possible road hazards.
PART 1. DIFFERENT IN-BUILT NIGHT VISION CAMERA IN VARIOUS CARS
The automotive industry is far ahead of time and has developed cars with built-in NVS that allows the driver to have a brightened road while travelling. The obstacles that are otherwise invisible to the driver becomes visible on the car's display. The evolving cars have two types of NVS which can be defined as:
Passive night vision: long range, simpler image
The passive night vision or far-infrared (FIR) system detects thermal radiation emitted by surrounding animals and humans through the thermographic camera. Cold objects (parked cars) and warm objects ( pedestrians, animals) are presented as dark and light images from a high viewing range of 1000f/300m. But it is less effective in warm weather. BMW, Audi and Honda have a series of vehicles with the passive system.
BMW has a unique pedestrian detection system that is able to detect infrared radiations emitted by various objects. The thermal camera produces images varying according to their temperature and warns the driver about the road environment ahead. With the help of imaging sensors, the camera can sense the obstacles on the road from a good 100yard and then display it on the navigation system in the form of a black and white image. The signal appears in the form of a yellow tint.
Audi's NVS has a thermal camera with a visual angle of 26°. The thermal camera is able to recognize pedestrians due to their body heat from a distance of 300m. The camera then projects a yellow alert on the Virtual cockpit display. The driver receives a red sign for a person crossing the road along with an audio-visual warning.
Active night vision: shorter range, lifelike image
Active night vision system or near-infrared (NIR) operates by using the infrared light source built within the car. This light source is able to illuminate objects beyond the reach of headlights and provide a monochromatic image from a long range of 250m. The infrared camera is powerful enough to produce a high-resolution image on the display. This system is suitable for warmer weather conditions.
- Mercedes Benz
Mercedes Benz has developed the Night View Assist Plus. This technology utilizes LED and infrared technology in order to display the road hazards on the instrument cluster. The system operates at a speed of 10km/h with a viewing range of 160m without causing the effects of glare.
Toyota has an active night vision system that illuminates the road situation and displays the outcome on the LCD screen in the instrument panel. The system visualizes road conditions from a distance of 200m and aids the driver in staying safe by detecting pedestrians only.
PART 2. THE MOST APPLICABLE NIGHT VISION CAR CAMERA -- LANMODO VAST PRO
For many conventional car users, there are certain external night vision system openly available in the market. The most reliable yet applicable system is provided by Lanmodo. The Lanmodo Vast Pro night vision camera has the capability to provide a realistic image of the road. The system comes in a perfect package and the uniqueness of the system lies in its characteristics listed below:
Newest night vision imaging technology
Lanmodo Vast Pro is equipped with the latest technology that involves a Sony chip. This chip works on the principle of low light image technique and uses an active infrared to produce a high-definition image on the wide 8" IPS display. The lens of the camera has 7 pieces of glass and has no interface with the car screen.
- 1080P colour night vision display
The dominant feature of this system is its high quality and colourful display. The camera is advance enough to exhibit a 1080p HD video. The resolution provides you with the exact image of the road in front of you.
- Wide viewing angle and long distance covered
Night driving becomes safer when you are well informed of the road ahead. This device has a viewing angle of 45° that shows the route from a 300m distance.
- Affordable and portable
The product takes a few minutes to install. It can be connected via 12v cigarette lighter or through the OBD port available in the bundle. With all, it's superior features the price tag attached to it is rather affordable.
