DX2A Thermal Imaging Gimbal: Compact 4K EO/IR Imaging for Micro UAVs
Why the DX2A Stands Out in Micro UAV Imaging
The DX2A thermal imaging gimbal gives micro UAV operators a compact way to capture visible and infrared imagery during day or night missions. This triple-mode micro-pod combines a 4K EO camera, a 640 × 512 thermal camera, and integrated vehicle and human tracking functions. As a result, one lightweight payload can support aerial surveillance, public security, environmental monitoring, and forest fire observation. The payload weighs 105 g without a shock absorber or 120 g with one installed. Therefore, it suits platforms where every gram matters. The 3-axis servo-stabilized design also helps maintain a steady view during flight and high-speed maneuvers. Specifically, the stabilization accuracy reaches 0.1 mrad, while the EO tracking capability reaches at least 40°/s. Moreover, the continuous EO zoom provides 10× optical magnification and up to 40× hybrid zoom. Operators can switch between wide-area viewing and narrower target inspection without changing lenses. Meanwhile, the EO camera records 3840 × 2160 video at 30 fps. The infrared module records 640 × 512 video at 50 fps through a 13 mm lens. It also provides a 32.9° × 26.6° field of view. In addition, picture-in-picture viewing can combine visible-light and thermal scenes on one display. Rich OSD overlays can show camera, target, and robot information. This helps teams interpret live imagery quickly. The DX2A also supports Ethernet and RTSP video output with H.264 or H.265 encoding, plus MP4 storage. For integration, the unit accepts 12–28 V DC power and supports UART control through TTL 3.3 V and RS232 protocols. SBUS is optional. Furthermore, its CNC-machined metal housing is designed for EMC compliance, interference resistance, strength, and heat dissipation. The operating range extends from −20°C to +55°C. Consequently, the DX2A thermal imaging gimbal offers a practical balance of imaging power, tracking automation, and compact UAV integration.

4K EO and Infrared Imaging in One Payload
The visible-light camera provides detailed 4K imagery at 30 fps. Its wide field of view measures 84° × 53°. The telephoto view measures 20° × 11°. Therefore, operators can scan a broad area before narrowing attention to a specific subject. The 10× continuous optical zoom creates smooth transitions between these viewing perspectives. In addition, 40× hybrid zoom supports closer inspection when distance separates the UAV from its target.
Meanwhile, the infrared camera adds useful information when visible light is limited. It records 640 × 512 thermal video at 50 fps. The 13 mm lens produces a 32.9° × 26.6° field of view. As a result, the sensor can support road, building, industrial, and heat-signature monitoring. Users can select palettes such as White Hot, Black Hot, Iron Red, Rainbow, and Fusion. Furthermore, the thermal module may provide 6–15 palette options, depending on the connected infrared module.
Stabilization and Automatic Target Tracking
Stable imagery is essential when a UAV is moving, turning, or hovering in variable conditions. Accordingly, the 3-axis servo gimbal uses stabilization accuracy of 0.1 mrad. Its angular position accuracy is listed as no more than 0.3°. The system also supports yaw rotation of ±110°, pitch rotation from −100° to +40°, and roll rotation of ±45°. Moreover, maximum angular velocity reaches at least 100°/s.
The integrated tracking functions add another layer of automation. The DX2A supports identification and automatic tracking for vehicles and humans. Tracking remains available during zoom, with a stated capability of at least 40°/s. Therefore, operators can spend less time correcting the camera view manually. This is useful for public security, law enforcement, traffic monitoring, and search operations.
In addition, rich OSD overlays can display camera information, target information, and robot information. A temperature bar overlay and visibility controls support thermal analysis. Consequently, the payload can deliver both imagery and mission context through a single interface.
Integration, Housing, and Mission Applications
The DX2A is designed for integration into compact UAV and robotic systems. Its 12–28 V DC input accommodates a broad range of power architectures. Average power consumption is below 6 W, while maximum consumption is below 15 W. Therefore, system designers can evaluate the payload without adding unnecessary power hardware. Ethernet and RTSP outputs support network video workflows. H.264 and H.265 encoding provide flexible streaming options, while MP4 supports video storage.
Control options include UART, TTL 3.3 V, and RS232 protocol support. SBUS is available as an option, and TTL is the default control mode. The product imagery also shows integrated interfaces within the housing, with no external B2B connectors exposed. Furthermore, the CNC-machined metal shell is described as EMC-compliant, anti-interference, high-strength, and designed for efficient heat dissipation.
The compact body measures approximately 66.6 mm high, 47.6 mm wide, and 54.4 mm deep. The mounting diagram shows a top diameter of 26 mm, a lower mounting diameter of 32 mm, and four M2 mounting holes. It also identifies a 20.63 mm dimension, an R22.50 mm radius, and 45° mounting angles. As a result, integrators have clear physical reference points when planning a custom mount.

Why Choose the DX2A for a Micro UAV?
The DX2A brings several mission-critical capabilities into a very small payload. Firstly, its 105 g base weight helps preserve aircraft capacity. Secondly, the 4K EO camera provides detailed daylight imagery and flexible zoom. Meanwhile, the thermal camera extends observation into darkness and low-visibility conditions. Automatic tracking can then help maintain attention on moving vehicles or people.
In addition, network streaming and multiple control interfaces simplify connection to ground systems. The 3-axis gimbal supports stable viewing, while picture-in-picture and OSD overlays improve situational awareness. Finally, the metal EMC housing and −20°C to +55°C operating range support professional field deployment. Taken together, these features make the DX2A a capable thermal imaging gimbal for micro UAVs, robotic platforms, and demanding surveillance workflows.
