The XTC2640LT delivers 640×512 LWIR imaging with 1180 m person detection in a UAV-optimised lightweight thermal camera, targeting airborne border patrol and counter-UAS ISR payloads on compact multirotor platforms.
Counter-drone and border surveillance programmes deploying thermal sensors on rotary-wing UAV platforms have encountered a consistent integration obstacle: the thermal cameras providing adequate 640 × 512 resolution for detection and recognition at operationally relevant ranges typically exceed the payload mass budget of Group 1 and lightweight Group 2 platforms by a margin that forces either a payload compromise or an airframe upgrade. That mass constraint has driven demand for thermal cores that preserve 640 × 512 resolution while achieving the sub-400 g all-up weight that keeps lightweight gimbal payloads within the flight envelope of compact ISR multirotor platforms.
640 × 512 Thermal Imaging Optimised for UAV Payloads
The XTC2640LT addresses that constraint directly as a UAV-optimised lightweight thermal camera built around a 640 × 512 LWIR uncooled sensor paired with a 13 mm lens, achieving an all-up weight suited to compact gimbal integration without sacrificing the resolution that makes 640-class thermal sensors operationally useful. Person detection reaches 1180 m and vehicle detection extends to 3380 m, covering the tactical observation ranges required for border corridor surveillance and counter-UAS cuing from a lightweight airborne platform. NETD at ≤ 50 mK maintains reliable thermal contrast in the near-ambient temperature differential environments encountered during early morning and late evening patrol cycles when target-to-background temperature differences are at their minimum.
UAV Border Patrol and Counter-UAS Applications
Border patrol multirotor platforms operating at altitudes of 100 to 200 m cover ground surveillance corridors most effectively when the thermal sensor can detect person-class heat signatures at ranges of 800 m or greater from platform position, providing the angular geometry to cue ground response assets before contacts reach covered terrain or cross-fence lines. At 1180 m rated person detection, the XTC2640LT provides that cuing geometry from a lightweight airborne platform that can be deployed rapidly from vehicle-mounted launch systems without ground preparation infrastructure. Counter-UAS programmes using thermal sensors for small drone detection benefit from the 640 × 512 resolution at compact gimbal size, which supports the signature resolution needed to classify small multirotor threats against cluttered ground and sky backgrounds at the ranges where intercept decisions must be made.
Gimbal Integration and Payload Design Compatibility
The XTC2640LT is compatible with lightweight two-axis and three-axis gimbal systems used on tactical ISR multirotor platforms, with video output and control interfaces suited to the embedded compute architectures of current-generation UAV mission systems. As thermal sensor procurement for airborne ISR platforms shifts toward the 640-class resolution tier across both military and border security programme types, lightweight thermal cameras that deliver this resolution within Group 1 payload constraints are positioned to define the baseline sensor specification for the next generation of compact tactical surveillance UAVs.
