Sirius HD 1280
The next era of precision detection. The Sirius HD series combines a 1280 × 1024 HD thermal sensor with ≤18 mK sensitivity for detailed thermal imaging in demanding outdoor conditions.
Designed for wildlife observation, outdoor exploration and professional use, the Sirius HD range pairs high-resolution thermal imaging with a clear OLED display and versatile optics.
Excellence in HD thermal imaging
The 1280 × 1024 HD sensor and ≤18 mK NETD sensitivity help reveal fine temperature differences and deliver detailed thermal scenes in low light and darkness.
PIPS 2.0: pioneering image enhancement
PIXFRA’s self-developed PIPS 2.0 image processing system is designed to optimise electronic zoom, reduce image noise, improve image stability and enhance details for a clearer viewing experience.
Versatile aperture for optimal image capture
The PFI-SA70D features a dual-field optical system with 35 mm and 70 mm focal lengths. Its apertures are F0.92 at 35 mm and F1.1 at 70 mm, helping adapt the view to different observation situations.
Expansive OLED display for unmatched clarity
The 0.49-inch, 1920 × 1080 OLED screen offers a detailed viewing image, helping bring distant thermal scenes into clear view.
Adaptive 35 mm–70 mm optics
Switch between a wider 35 mm view for searching and a narrower 70 mm view for longer-range observation. This flexibility supports the process from scanning an area to inspecting a target in greater detail.
Detection range up to 3,600 metres
The PFI-SA70D lists a detection distance of up to 3,600 m using the 70 mm focal length. Detection range is not the same as recognition or identification distance; actual results depend on target size, environment and conditions.
