Vehicle-Mounted Thermal Cameras

Vehicle Thermal Camera Selection Guide

A vehicle thermal camera shows the road ahead by heat rather than light, so pedestrians, animals and vehicles stand out in darkness, headlight glare, smoke and haze. JOVSTAR automotive thermal night vision systems combine a VOx thermal camera (256×192, 384×288 or 640×512) with an AI processor that recognizes people and vehicles and warns the driver, and connect to the display that suits the vehicle.

Choose a standalone display system when the vehicle has no suitable screen or you want the simplest retrofit. Choose an original-screen system to show the thermal image on a wired CarPlay screen, an Android head unit or a supported factory screen. Choose a video-output unit (AHD, HDMI or CVBS) when the image goes to a monitor, electronic mirror or third-party system.

All systems use 8–14 μm VOx thermal cameras with 12 μm pixels, NETD 40 mK and IP67 housings. See each product page for full specifications.

How a Vehicle Thermal Night Vision System Works

A JOVSTAR system has three parts: a thermal camera outside the vehicle, a processing unit with an AI processor, and a display or video output with warnings.

The thermal camera

The camera uses an uncooled VOx detector behind an athermal fixed-focus lens, so it needs no focusing as temperature changes. It sits outside the cabin, usually in the front grille, because thermal infrared does not pass through windshield glass. A high-strength protective window covers the lens, and automatic window defrosting starts below 2℃ and stops above 7℃. The camera draws under 1 W, or under 3 W with heating on, and works from -30℃ to +70℃ on most systems.

AI recognition

A 3 TOPS neural processing unit runs recognition of people and vehicles at 21 frames per second or more, with a stated identification rate of 95% or higher, and estimates their distance. The JV-ADS-S7 counts cyclists and motorcyclists as people, and the JV-ADS-S5 also recognizes animals.

Display and warnings

Recognized targets are highlighted on screen, and the system gives visual and audible warnings. Depending on the model, warnings come from a built-in speaker, an external speaker or the car horn, can be linked to vehicle speed through GPS, and offer three warning levels, adjustable distances or custom alert zones.

Standalone vs Original-Screen vs Video-Output Systems

The main choice is where the driver will see the image.

• Standalone display systems (JV-ADS-S5, JV-ADS-S7, JV-ADS-S7P) include their own 5″ or 7″ screen and are the simplest to retrofit in any car, RV, truck or machine. The JV-ADS-S7P adds CarPlay, Android Auto and multimedia, so one screen does both jobs.
• Original-screen systems show the image on the vehicle’s existing screen: through wired CarPlay, through an Android head unit over USB, or through a dedicated decoder for supported factory screens. They give a cleaner installation without an extra display.
• Video-output units send the image as AHD, HDMI or CVBS to monitors, streaming rear-view mirrors, digital instrument screens or fleet systems. They suit fleets, special vehicles and system integrators.

What Determines Detection and Recognition Distance

For a vehicle thermal camera, distance depends mainly on the lens focal length and the detector’s pixel size, and on whether you mean detection, recognition or an AI warning.

With the standard 9.1 mm lens and 12 μm pixels, JOVSTAR systems detect a person at 859 m and a vehicle at 1,263 m, and recognize them at 214 m and 316 m. AI recognition, which triggers warnings, works to about 80 m for people and 200 m for vehicles. At 100 km/h a car covers 214 m in under 8 seconds, so recognition distance translates directly into reaction time.

Lens choice trades distance for coverage. The JV-ADS-S5 offers seven camera options:

With the same lens, a higher resolution does not add distance; it widens the field of view. A 640×512 camera with the 9.1 mm lens covers 48° × 39° instead of 18° × 13°, which helps on curves, at junctions and in town. Wide-angle options such as 120° suit low-speed machines and close surroundings; long lenses suit highways and open roads.

Installing a Vehicle Thermal Camera

• Power: most JOVSTAR systems accept DC 9–36 V, which covers 12 V cars and 24 V trucks and machinery; the JV-ADS-S7 and S7P can run from the cigarette lighter socket.
• Camera position: mount the camera at the front, outside the windshield, with a clear view of the road. The 256×192 camera measures 40 × 30 × 26 mm and weighs 60 g; the 384×288 and 640×512 cameras measure 42 × 60 × 42 mm and weigh 185 g.
• Connection: cameras use a 4-pin automotive connector; video-output units offer aviation or RCA connectors.
• Display: check CarPlay, Android or factory-screen compatibility before choosing an original-screen system; standalone systems need no compatibility check.

Vehicle Thermal Camera Applications

JOVSTAR vehicle thermal systems are used in four main kinds of vehicles.

Passenger cars

Night driving assistance on unlit roads, with original-screen systems for CarPlay, Android head units and supported factory screens, or the JV-ADS-S7P where the car needs CarPlay as well.

RVs and commercial vehicles

Standalone systems and DC 9–36 V units suit RVs, vans, trucks and buses, with wide-view 640×512 cameras for junctions and depots.

Construction machinery and special vehicles

Wide-angle cameras on the JV-ADS-S5 show people near slow-moving machines, and AHD or CVBS output connects to existing monitors.

Fleets and system integrators

Video-output units feed fleet monitors, streaming rear-view mirrors and situational awareness systems. See the Vehicle-Mounted All-Weather Situational Awareness Solution.
