WEOM HD CMOS LWIR Uncooled Module

HD 1280 × 1024 Resolution — Four Times the Detail of VGA Thermal Cores

The WEOM HD is built around an uncooled LWIR microbolometer with 1280 × 1024 pixels on a 12 µm pitch — 1,310,720 independent thermal measurement points, four times the 327,680 pixels of a conventional 640 × 512 VGA thermal core. In practice, higher pixel count delivers two advantages that matter to integrators. First, at the same field of view each pixel covers a smaller area of the scene, so fine details — a person’s posture, a vehicle’s outline, a small drone against the sky, or a hot component on a distant structure — are rendered sharply instead of blurring into a few pixels. Second, at the same angular resolution, an HD core covers a wider field of view, letting a single camera watch more of the scene without sacrificing detail. This translates directly into detection, recognition and identification (DRI) range. According to Workswell’s Johnson-criteria calculations, the WEOM HD with the 83 mm lens can detect a standing human at about 4,380 m and a vehicle at about 10,610 m, while the 25 mm lens offers a 34° × 27° wide view for situational awareness. For UAV, border surveillance and maritime systems, this HD detail is what turns a thermal blob into an actionable target.

CMOS Digital Interface on an LWIR 8–14 µm Platform — Built for Direct Hardware Integration

The CMOS configuration of the WEOM HD is aimed at integrators who design their own electronics. Rather than delivering video through a finished connector such as HDMI or USB, the core’s digital video is intended for board-level connection to the integrator’s own processor, FPGA or embedded computer — including platforms such as NVIDIA Jetson, Raspberry Pi and NXP processors, which Workswell lists as compatible. This removes intermediate conversion stages, saving space, weight and power in tightly packaged gimbals, sights and camera heads. All advanced functions are controlled through Workswell’s unified TCSI serial interface, independent of the video path. The 8–14 µm LWIR band is the natural choice for passive day/night imaging: objects near ambient temperature emit most strongly here, and LWIR penetrates smoke and light haze better than visible cameras, delivering clear imagery in total darkness, at dusk and in poor weather.

HD 1280 × 1024 Resolution — 1.3 Megapixel Thermal Detail

Over 1.3 million thermal pixels on a 12 µm pitch deliver four times the detail of VGA cores. Integrators gain longer DRI range with the same lens, or a wider field of view with the same detail — a decisive advantage for surveillance, long-range observation and high-altitude UAV imaging.

High Thermal Sensitivity — <30 mK NETD

Resolves temperature differences below 0.03 °C, producing crisp, low-noise images of low-contrast scenes. High sensitivity keeps detail visible in fog, rain, humid coastal air and thermally uniform night-time backgrounds where lower-sensitivity cores produce flat, washed-out images.

CMOS Digital Interface for Direct Hardware Integration

The CMOS configuration connects the core’s digital video directly to the integrator’s own electronics, eliminating intermediate conversion boards. This saves weight, volume and power in compact gimbals, handheld devices and embedded AI camera heads, while keeping full control over system architecture.

Advanced FPGA Image Processing

On-board FPGA processing provides automatic gain control with plateau histogram equalisation, manual brightness/contrast, median spatial filtering, 2× and 4× temporal filtering, 14 colour palettes (two user-definable), image flip/mirror and a user dead-pixel correction wizard — delivering display-ready images without host-side processing.

Flexible Optics — Four Lenses or Lensless Delivery

Choose 25 mm (34° × 27°), 35 mm (24° × 19°), 50 mm (17° × 13°) or 83 mm (10° × 8°) fixed-focus lenses, or order the core lensless with an M34 thread to fit your own optics, zoom assembly or athermalised lens design.

Low SWaP for Mobile Platforms — <85 g, 2.9 W

At under 85 g without the lens, 43 × 42 × 51 mm and typically 2.9 W from 5 VDC, the WEOM HD minimises payload weight and power draw — extending UAV flight endurance and battery life in handheld monoculars and binoculars.

ITAR-Free, Designed and Made in Europe

Designed and manufactured by Workswell in Prague, Czech Republic, the WEOM HD is ITAR-free, so it is not subject to US ITAR restrictions. This simplifies procurement, integration and onward export for Indian OEMs building defence, homeland security and export-bound platforms.

Fast Start-Up, Unified Control and SDK Support

Starts imaging in under 5 seconds. Configure it with the WEOM GUI desktop software, control every function through the TCSI serial interface, and integrate using C++ and Python libraries or the SEP REST API. Remote firmware updates keep fielded systems current.

UAV and Drone Payloads

Provides HD thermal imaging for ISR, inspection and mapping payloads where every gram and watt counts:

• ISR and surveillance gimbals: 1280 × 1024 imaging with narrow-FOV lenses enables target detection and identification from higher altitudes and longer stand-off distances, supporting Indian drone manufacturers building payloads for defence, paramilitary and police users
• Infrastructure inspection drones: high-detail thermal imagery of power lines, solar farms, pipelines and substations, letting operators spot small hotspots from safe inspection distances in a single flight pass
• Payload SWaP optimisation: under 85 g and about 2.9 W, the core preserves flight endurance on small multirotor and fixed-wing platforms developed under India’s growing domestic drone ecosystem

Unmanned Ground Vehicles and Robotics

Adds reliable day/night perception to UGVs and autonomous robots operating in difficult conditions:

• UGV navigation and obstacle detection: passive LWIR imaging reveals people, animals and obstacles in total darkness, smoke and dust, complementing visible cameras and LiDAR in the perception stack
• EOD, CBRN and hazardous-area robots: HD thermal views help operators assess suspicious objects, locate casualties and monitor heat sources remotely, keeping personnel out of danger zones
• Autonomous patrol robots: edge-AI processing on NVIDIA Jetson or similar platforms can run person and vehicle detection directly on the WEOM HD video stream for perimeter patrol applications

Defence and Border Surveillance

Delivers long-range, high-detail thermal observation for defence integrators and research laboratories:

• Thermal monoculars, binoculars and observation devices: HD resolution and <30 mK sensitivity give soldiers and border personnel clear imagery through darkness, fog and smoke, with low power for long battery life
• Long-range border and coastal surveillance: 83 mm optics support human detection at about 4.4 km (Johnson criteria), supporting fixed and mobile surveillance systems along India’s land borders and coastline
• Defence R&D and indigenous development: ITAR-free supply supports DRDO laboratories, defence PSUs and private Indian defence OEMs developing indigenous thermal systems under Make in India programmes

Maritime and Coastal Security

Improves navigation safety and situational awareness at sea, day and night:

• Night navigation and collision avoidance: thermal imaging reveals small boats, buoys, debris and floating obstacles invisible to the naked eye after dark, supporting safer navigation for naval, coast guard and commercial vessels
• Man-overboard and search operations: the human body’s heat signature stands out sharply against cool water, enabling faster location of persons in the water during night-time rescues
• Port and harbour security: fixed thermal cameras monitor approach channels, berths and waterfronts at India’s major and minor ports, detecting unauthorised vessels and swimmers regardless of lighting

Search, Rescue and Disaster Response

Helps responders locate people quickly when every minute counts:

• Disaster response: drone and handheld thermal cameras help NDRF, SDRF and fire services locate survivors in collapsed structures, flooded areas and landslide zones, where visual search is slow and unreliable
• Missing-person searches: high-resolution thermal imaging from UAVs scans forests, hills and open terrain rapidly at night, detecting body heat over wide areas
• Firefighting support: thermal imaging sees through smoke to locate hotspots, trapped occupants and fire spread, and supports forest fire monitoring in hill states

Security, Perimeter and Critical Infrastructure

Provides reliable 24/7 detection for fixed and PTZ security cameras:

• Perimeter intrusion detection: thermal cameras detect human and vehicle intrusion in complete darkness and poor weather at power plants, refineries, airports and data centres across India
• PTZ and multi-sensor camera integration: the compact core and lensless option suit integration into PTZ heads and dual-sensor (thermal + visible) security cameras built by Indian security OEMs
• Anti-UAV and drone detection: LWIR imaging detects small drones by their warm motors and batteries against the sky, supporting counter-drone systems protecting sensitive installations

Machine Vision, Industrial and Research Applications

Supports industrial monitoring, embedded vision and academic research:

• Machine vision and intelligent systems: direct CMOS integration with embedded processors enables thermal AI cameras for process monitoring, fire prevention and automated inspection
• Industrial monitoring: HD thermal imaging of production lines, electrical cabinets and storage areas helps detect overheating early and prevent unplanned downtime
