Technical Specifications

Core Performance Advantages

All-Weather Reliable Operation: Your perception system remains fully functional regardless of environmental challenges. The product operates effectively through darkness, rain, snow, and fog. It remains completely immune to glare from oncoming headlights or direct sunlight, ensuring consistent performance when visible light cameras fail.

Extended Detection Range: This system detects vehicles up to 200m and pedestrians up to 150m—three times farther than conventional high beams. This extended range provides 5-8 seconds of additional reaction time, significantly improving safety margins for decision-making systems.

Passive Sensing Technology: Operating as a completely passive sensor, the camera emits no signals and generates zero electromagnetic interference. This characteristic allows seamless integration with radar, LiDAR, and other active sensor systems without cross-talk issues.

AI-Ready Living Target Detection: Advanced algorithms achieve over 95% accuracy in identifying pedestrians and animals. The thermal signature differentiation supports Forward Collision Warning (FCW) and Autonomous Emergency Braking (AEB) functions with superior false-positive rejection rates.

Automotive-Grade Durability: Designed to withstand harsh automotive environments, the system operates reliably across temperatures from -40°C to +85°C. IP67 protection ensures resistance against water ingress and dust contamination, while design compliance with AEC-Q100 certification and ISO 26262 (ASIL-B) functional safety standards guarantees long-term reliability.

Key Application Scenarios

Advanced Driver Assistance Systems Integration: The Automotive Thermal Car Camera serves as a critical redundant sensor layer for Level 2+ ADAS deployments. It provides reliable pedestrian detection when shadows, backlighting, or tunnel transitions compromise RGB camera performance.

Autonomous Vehicle Perception Stacks: For Level 3-5 autonomous platforms, this thermal imaging solution adds an essential perception modality. When LiDAR pulses scatter in fog or dust and radar struggles with stationary object classification, thermal signatures maintain continuous hazard awareness.

Commercial Fleet Safety Enhancement: Long-haul trucking operations, mining equipment, and agricultural machinery benefit from 24/7 operational visibility. Thermal detection prevents costly collisions with wildlife on rural highways and enhances safety in low-visibility industrial zones.

Smart City Infrastructure: Traffic monitoring systems utilize thermal detection for vehicle counting and queue length measurement regardless of lighting conditions. The technology enables consistent data collection across day-night cycles without illumination infrastructure.

FAQ

Q: How is thermal imaging better than visible light cameras for driving at nite?

A: Thermal cameras detect infrared light emitted by all things above absolute zero . They create images based on heat fingerprints , not reflected light . This basic distinction means that the product can visualise pedestrians, animals and cars by their body heat or engine warmth, irrespective of ambient light conditions. Thermal sensors work just as well in total darkness, fog or smoke, unlike visible light cameras which need external illumination and suffer from headlight glare. The technology boasts detection ranges of up to 150-200 meters down the road, well beyond the effective range of ordinary headlights (50-70 meters), allowing perception systems crucial additional seconds to recognise threats and respond.

Q: Can thermal cameras operate reliably in extreme temperature environments?

A: Yes, automotive-grade thermal imaging systems like the solution from MHNV® are designed to work from -40°C to +85°C. The uncooled VOx microbolometer has temperature adjustment algorithms integrated in the software to provide steady NETD performance over this range. Units suitable for deployment in cold climates have an automated lens heater element that activates at low temperature to prevent the formation of ice and snow on the germanium optical window. Thermal management systems protect sensor electronics during high-temperature summer activities or when located near engine compartments. The broad operating range is confirmed by manufacturing quality control thermal cycling tests according to ISO 16750-4 standards.

Q: How is heat detection integrated into existing ADAS sensor fusion architectures?

A: The product is a supplementary perception layer for multi-sensor fusion frameworks. It outputs standard video formats via RCA interface and communicates via USB type C for configuration and delivery of metadata. Thermal imaging is passive, meaning it does not transmit signals and hence does not electromagnetically interfere with radar or Lidar devices. Sensor fusion methods are used to generate robust environmental models by combining thermal object detection with radar velocity data and LiDAR point clouds. Thermal data allows continued danger tracking when optical sensors lose contrast (fog, backlight) or LiDAR returns become weak (rain, snow), thereby lowering false negatives in pedestrian detection systems.

Q: What is the expected detection accuracy for different categories of objects?

A: Detection performance is a function of the target thermal signature strength, ambient conditions, and sensor resolution. At the 640x512 resolution configuration, the system can consistently recognise adult pedestrians at 150m and normal automobiles at 200m. Classification methods achieve over 95% accuracy in identifying pedestrians, animals and vehicles by examining thermal signature patterns and motion features using artificial intelligence. Smaller items, such as motorcycles or toddlers, may be detected at correspondingly closer distances. Sophisticated image processing compensates for atmospheric attenuation providing adequate image quality (even in mild fog) where visible light sensors totally fail. For essential safety applications cautious detection range specifications are provided to cover worst-case atmospheric conditions.

Q: Is frequent maintenance or calibration of the thermal camera necessary?

A: Today's automobile thermal cameras use shutterless calibration technology, which performs autonomous internal calibration cycles without driver engagement. The solution constantly checks the sensor drift and provides real-time adjustment to keep the image uniform. Older methods required the shutter to be cycled manually . This method ensures continuous operation . Maintenance is low on the outside, occasional cleaning of the germanium lens glass keeps the IR transmission at its best. The IP67-rated housing protects the internal components from contamination by the environment. over fleet deployments, manufacturers advocate annual functional verification to ascertain detection range performance and video output quality, but the robust design typically enables specification compliance to be maintained over the operating lifetime of the product without adjustment.
