Système d'imagerie thermique infrarouge gyrostabilisé série GST280

 

Visible light and infrared thermal imaging

The 1920×1080 pixel high-definition visible light camera can provide users with clear images during the day, while the infrared thermal imaging is equipped with a 640×512 pixel detector, which is suitable for use in dark and complex weather conditions, providing clear thermal images. En même temps, the device is also equipped with a synchronized zoom 1km laser illuminator (equipped with GST280-T), which can work with a visible light camera to still obtain clear images even in dark environments, making it convenient for law enforcement and evidence collection at night. The GST280 series is compatible with various monitoring systems, and both power and signal can be directly connected to ordinary monitoring and security systems.

 

Waterproof performance

The GST280 casing has undergone strict waterproof design, which can be directly rinsed with water. Strict waterproof measures have also been taken for mechanical interfaces and cable joints. The GST280 has achieved IP66 protection and can be used 24/7 in complex climates such as salt mist, high humidity and cold.

 

Gyro stability

The gyro stabilization function enables users to obtain clear and stable images under complex ground or water conditions. The GST280 precision rotation platform adopts advanced gyroscope stabilization technology, which has a self-stabilizing function. When a vehicle or vessel shakes, the platform drives the load sphere to compensate in the opposite direction based on the gyroscope signal, so that the direction of the camera inside the sphere remains unchanged, and the stability can reach ± 0.1mrad, basically eliminating the effect of vehicle or vessel shaking on visual observation and achieving image stability.

 

Image tracking function (optional)

In tracking mode, the turntable can automatically rotate as the tracked target moves. Users can select targets to track in infrared or visible light images by simply pressing a button to enter tracking mode.
