DS403 at a Glance

• Day and night imaging: Visible-light and infrared sensors support observation across changing conditions.
• 4K visible light: The wide-field camera provides 3840 × 2160 resolution.
• Thermal detail: The infrared camera uses 640 × 512 resolution to identify heat sources and subtle temperature differences.
• AI assistance: Automatic tracking and recognition support vehicles and standing people.
• Laser ranging: The system measures distances from 15 m to 3000 m under the stated vehicle target condition.
• Compact payload: The pod measures approximately ≤Ø102 mm × 126 mm and weighs ≤580 g.

Four Imaging Functions in One Compact System

The DS403 uses several sensing and positioning functions to build a more complete observation picture. First, its visible-light system includes short-focus and long-focus cameras. The wide field of view measures 38.4° × 22.2° with an 8 mm focal length. Meanwhile, the narrow view measures 12.7° × 7.2° with a 25 mm focal length and 1920 × 1080 resolution. This combination lets operators scan a broad scene and then examine a selected area in greater detail.

Next, the infrared channel provides 640 × 512 thermal resolution and a 14.6° × 11.7° field of view with a 30 mm focal length. Therefore, it can help operators locate heat sources in darkness and other difficult scenes. The product images show monochrome thermal views of buildings, roads, bridges, and surrounding terrain. In addition, the laser emission and reception modules support distance measurement to a selected target.

Stabilization and AI Tracking for Moving Scenes

Stable footage is important when a payload scans from a moving platform. For that reason, the DS403 uses two-axis gyro stabilization. Its stabilization accuracy is ≤0.2 mrad, while angle measurement accuracy is ≤0.3°. The azimuth range extends from -150° to +150°. The pitch range extends from -90° to +30°. Furthermore, maximum angular velocity reaches at least 60°/s, and maximum angular acceleration reaches at least 100°/s². The pan-tilt system can therefore coordinate horizontal and pitching movement during observation.

The AI module adds another layer of support. It provides 6T AI computing power and reaches a maximum image-recognition frequency of 50 Hz. Specifically, the system can monitor target identifiers and movement paths. It can also adjust camera orientation and lens zoom to keep a target centered. The demonstration imagery shows overlays for personnel and vehicles. Consequently, operators can spend less time making continuous manual corrections during a surveillance task.

Technical Specifications and Integration Details

Integration is supported by a 14 VDC to 28 VDC power input, a one-channel network video interface, and a one-channel RS232 asynchronous serial port. Additionally, the compact metal housing is described as shock-resistant and includes fault-diagnosis functions. The physical drawings show a body diameter of approximately 100 mm, a front height of 124 mm, and mounting details including a 30 mm mounting width. These measurements can help integrators assess available space before selecting a platform.

Where the DS403 Can Be Used

The DS403 is designed for observation tasks that benefit from multiple imaging modes. For example, operators can use visible-light cameras for daytime road and urban monitoring. At night, thermal imaging can help locate heat sources and maintain awareness in low-light conditions. Similarly, laser ranging can provide real-time distance information for a selected vehicle or other target.

• Tactical observation: Combine stabilized imaging, AI recognition, and ranging during reconnaissance tasks.
• Security monitoring: Observe broad areas and maintain attention on recognized people or vehicles.
• Search and rescue: Use thermal imagery to help locate heat sources during darkness or reduced visibility.
• Compact-platform integration: Consider the pod for suitable unmanned platforms after checking payload, mounting, power, and interface requirements.

A Practical Multi-Sensor Payload

Overall, the DS403 Miniature Electro-Optical Pod brings several useful capabilities into a small enclosure. It combines 4K visible-light imaging, 640 × 512 thermal imaging, AI recognition, automatic tracking, gyro stabilization, and laser ranging. Meanwhile, its ≤580 g weight and ≤10 W average consumption support compact-platform planning. The result is a flexible payload for day and night observation, provided that the intended platform meets the stated mounting, power, and interface requirements.
