The GIS-320 is built around a sensitive cooled InSb infrared detector that detects gas leaks by capturing unique spectral absorption signatures in the mid-wave infrared band. It combines gas imaging with radiometric data, allowing inspectors to visualise and quantify leak sources at a distance from industrial sites or pipelines. With a 320 × 240 thermal resolution, 30 Hz frame rate and advanced image modes, it provides clear and detailed thermal footage even in challenging lighting and environmental conditions. Flexible connectivity and onboard recording support efficient workflows — from live UAV feed to post-flight analysis and reporting for diagnostics and compliance.

Mid-Wave Infrared Gas Imaging

The GIS-320 uses a cooled MWIR infrared detector that senses gas absorption features invisible to the human eye, making it effective at detecting emissions like methane, propane, benzene and other hydrocarbons stored in pipelines and tanks. Its high thermal sensitivity (~10 mK) allows subtle emissions to be visualised clearly in real time.

Radiometric and Visual Dual-Mode Imaging

Combining thermal gas imaging with a Full HD visible camera enhances situational awareness. The thermal feed highlights gas plumes, while the visible image — with optical zoom and autofocus — helps investigators correlate leaks to physical infrastructure locations and document conditions for reporting or repair.

High-Resolution and Frame Rate

The 320 × 240 thermal resolution at 30 Hz output enables smooth, detailed imaging — crucial for dynamic inspections from moving UAVs, UGVs or from the ground. This frame rate supports safe, efficient sweeps over pipelines or complex industrial layouts.

Flexible Platform Integration

Designed as a compact, rugged payload, GIS-320 integrates seamlessly with unmanned aerial vehicles (e.g., DJI M600 series), ground robots or mobile inspection rigs. Interfaces like MAVLink, CANbus, SBUS and Ethernet facilitate control, streaming, geotagging and telemetry for professional survey operations.

Environmental and Safety Benefits

By enabling detection from a safe distance, this camera helps detect gas leaks before they escalate, reducing environmental impact and improving compliance with emissions monitoring programs. Its radiometric data also supports regulatory reporting and detection and repair (LDAR) program analytics.

Oil & Gas Inspection and Leak Detection

In upstream, midstream and downstream operations, gas leaks can have severe safety and environmental consequences. The GIS-320 camera detects methane and other volatile organic compounds along pipelines, compressor stations, storage tanks and wells — enabling rapid identification and mitigation of leaks without exposing personnel to risks.

Power Generation & Electrical Systems

SF6 gas — commonly used in high-voltage switchgear — can indicate insulation breakdown and equipment failure when leaking. GIS-320’s infrared gas imaging helps infrastructure teams detect such leaks early and maintain grid reliability.

Environmental Monitoring & Emission Surveys

Environmental agencies and industries monitor greenhouse gas emissions to comply with regulatory standards and assess climate impact. The GIS-320 identifies emission sources and quantifies plume behaviour, supporting regulatory compliance and environmental protection efforts.

Chemical & Industrial Facilities

Chemical plants, refineries and storage terminals handle hazardous gases that pose fire, health and safety risks. Constant aerial or ground-based thermal surveillance using GIS-320 enables facility teams to prioritise maintenance, prevent accidents and safeguard workers.

Emergency Response & Disaster Management

During incidents involving gas releases or industrial fires, rapid situational awareness is critical. GIS-320 provides first responders with thermal visualisation of gas clouds and heat sources, improving operational planning and community protection outcomes.
