Infrared Night Vision Camera

An infrared night vision camera is an on-board sensor that utilises infrared technology to "see" objects at night or in adverse weather conditions. Operating independently of visible light, it functions like a pair of "thermal imaging eyes" for the vehicle, serving as a vital driver-assist system to enhance driving safety in night-time and low-visibility environments.

💡 Operating Principle: Seeing "Temperature"

Unlike conventional cameras that rely on ambient lighting, infrared night vision cameras primarily detect the thermal radiation (infrared rays) naturally emitted by objects. Their operating methods are mainly split into two types:

• Passive Type (Thermal Imaging): Directly captures the thermal energy emitted by objects such as pedestrians and animals to generate images without requiring any light source. Its primary advantage is an extended detection range, though it cannot clearly distinguish non-heat-emitting road surface details and carries a higher production cost. This remains the mainstream route for automotive infrared applications today.

• Active Type (Near-Infrared): The vehicle actively emits infrared light (invisible to the human eye) and receives the reflected light to render an image. It clearly displays the full profile of cold targets such as road surfaces and lane markings—much like a monochrome photograph—though its detection range is relatively shorter.

🚀 Core Value and Industry Landscape

The true value of infrared night vision lies in bridging the capability gaps of optical cameras and radar in specific scenarios, providing crucial sensor redundancy for autonomous driving. It effectively addresses visual blind spots such as pitch-black unlit roads, blinding glare from oncoming headlights, and poor visibility caused by rain, snow, fog, or haze, delivering precise identification of pedestrians and animals.

• Reliable Performance: The technology is already highly mature. For instance, a mass-production unit achieves an accuracy rate of up to 96% within a 5-to-90-metre range for pedestrian detection, and up to 98% within 7 to 120 metres for vehicle detection. The maximum detection range extends up to 300 metres.

• Accelerating Mainstream Adoption: Once an exclusive high-spec feature reserved for RM1,000,000-class luxury flagships from Mercedes-Benz, BMW, and Audi, it is now rapidly filtering down to mainstream vehicles. Led by tech suppliers like Raytron, the technology is democratising quickly, with partnerships spanning over 10 automakers including BYD, Geely, and GWM across more than 20 models, and even coming as standard equipment on select off-road vehicles. In 2026, the world's first infrared Autonomous Emergency Braking (AEB) system officially entered series production on the Zeekr 9X.

🤝 Sensor Fusion: A Complement, Not a Replacement

Infrared night vision is not meant to replace existing sensors, but rather to serve as a critical layer of safety redundancy. It covers the blind spots of visible-light cameras in dark or high-glare conditions, while detecting living subjects that millimetre-wave radar struggles to differentiate. Through multi-sensor fusion setups such as "Infrared Thermal Imaging + 4D Imaging Radar", vehicles can achieve all-weather, ultra-reliable environmental perception.
