Pixfra Sirius S650 Thermal Monocular - 640x512, 12µm Detector, 50mm Lens

The Pixfra Sirius S650 is a slimline thermal imaging monocular that combines impressive performance with a refined, ergonomic design. Built around a 640×512, 12µm thermal sensor with an outstanding <18mK NETD sensitivity, it delivers exceptional thermal detail and makes it easier to pick up even the smallest heat signatures in challenging conditions. Paired with a powerful 50mm f/0.9 objective lens, the Sirius S650 offers a remarkable detection range of up to 2,600 metres, making it a superb choice for wildlife observation, conservation work, and long-range spotting.

Image quality is further enhanced by AI-powered image calibration, which learns from captured images to optimise clarity across a wide range of environments. A 1920×1080, 0.49-inch OLED display provides a sharp, vivid viewing experience with excellent comfort during extended use, helping to reduce eye fatigue while giving you a clear and expansive view of the scene ahead. With 3.45x optical magnification and digital zoom options of 1x, 2x, 4x and 8x, the Sirius S650 gives you the flexibility to assess subjects at varying distances with confidence.

Designed with Pixfra’s distinctive styling, the Sirius S650 features subtle premium touches such as carbon fibre accents, an embossed focus wheel, and a neatly integrated illuminated power button built into the Pixfra logo. Its simplified three-button control layout allows for intuitive one-handed operation, while the metal lens cover adds extra protection against dust, scratches, and day-to-day knocks. With 64GB of built-in storage, video recording, snapshot capture, Wi-Fi hotspot connectivity, and Hot Spot Trace, it is well equipped for both observation and recording in the field.

The Sirius S650 is also built for reliability in demanding conditions. It runs on a replaceable 18650 battery and offers up to 6 hours of battery life, with a quick-release battery system for fast swaps when needed. A robust IP67 rating and an operating range of -30°C to +55°C ensure dependable performance in harsh weather, while USB-C power support adds further convenience. Compact, capable, and packed with useful features, the Pixfra Sirius S650 is a high-performance thermal monocular that more than lives up to its name.
