Long-Range Thermal Imaging FLIR Cameras for Unmanned Surface Vehicles (USVs)

Advanced Gyro-Stabilized Thermal Imaging for Maritime Security

Modern unmanned surface vehicles (USVs) require reliable long-range sensors to detect, recognize, and identify threats in all conditions. Our gyro-stabilized thermal infrared cameras are engineered specifically for maritime and defense applications, delivering unmatched detection ranges, image stability, and 24/7 situational awareness.

Unlike traditional CCTV systems, thermal imaging does not rely on visible light. Instead, it uses passive infrared energy, allowing operators to see through darkness, smoke, glare, and challenging weather conditions. This makes FLIR thermal cameras the preferred choice for naval fleets, coastal security, and USVs conducting autonomous surveillance missions.

Understanding DRI: Detection, Recognition, and Identification

The performance of thermal imaging systems is measured by DRI (Detection, Recognition, Identification) criteria:

• Detection – Spotting a target at distance, even if it only registers as a small pixel cluster.
• Recognition – Determining the object’s class, such as human vs. vehicle, or car vs. truck.
• Identification – Differentiating specific target types, such as a tank versus an armored personnel carrier.

Our long-range cameras are optimized to deliver earlier and clearer DRI, providing critical time for USV operators to assess and respond to potential threats.

Why Thermal Imaging Outperforms Visible Cameras on USVs

Standard CCTV systems depend on light and contrast, making them unreliable in shadows, fog, or bright sun. In contrast, thermal FLIR cameras detect heat signatures, ensuring intruders and vessels can be spotted even when concealed by darkness, vegetation, or camouflage.

For USVs, this means:

• Day & night surveillance without artificial illumination.
• Enhanced maritime awareness in cluttered environments.
• Reduced false alarms when integrated with video analytics.
• Wide-area coverage with pan-tilt-zoom (PTZ) functionality.

Cooled vs. Uncooled Thermal Imaging for USVs

Cooled MWIR Thermal Cameras

• Operate in the 3–5 μm spectrum (MWIR).
• Feature cryogenic cooling for extreme sensitivity.
• Detect temperature differences as small as a few degrees.
• Provide ultra-long-range detection up to 20 miles (30 km).
• Ideal for homeland security, naval defense, and USVs requiring precision tracking.

Uncooled LWIR Thermal Cameras

• Operate in the 7–14 μm spectrum (LWIR).
• Use microbolometer sensors with no cooling requirements.
• Deliver multi-kilometer detection ranges with low maintenance and high reliability.
• Cost-effective, accounting for over 80% of thermal camera deployments.
• Widely used for coastal surveillance, port security, and commercial USVs.

EO/IR Multi-Sensor Systems for Unmanned Surface Vehicles

Our integrated EO/IR (Electro-Optical/Infrared) camera systems combine thermal imaging, high-definition visible cameras, and optional laser rangefinders. This fusion provides 360° maritime domain awareness, making them invaluable for:

• Autonomous USV patrols
• Coastal and harbor defense
• Counter-piracy and smuggling interdiction
• Search and rescue (SAR)
• Military and commercial fleet protection
