The Pixfra Sirius S635 is a handheld thermal imaging monocular built for night-time deer stalking, fox control and general wildlife observation. At its core is a 640×512, 12µm thermal sensor with ≤18mK NETD sensitivity, paired with a 35mm f1.0 lens that gives a detection range of up to 1,800m and 2.41x optical magnification (extending to 8x digitally). Images are shown on a crisp 0.49" 1920×1080 OLED display, and Pixfra's AI-powered calibration adjusts automatically to keep the picture clear as conditions change. The S635 carries Pixfra's signature styling — carbon-fibre accents, an embossed focus wheel and a three-button control layout built for one-handed use after dark — plus a metal lens cover to protect the optic from knocks and scratches in the field. A quick-release 18650 battery gives up to 6 hours of use, with spares swapped in seconds rather than minutes, and 64GB of built-in storage with Wi-Fi lets users save and review footage from a phone. Rated IP67 and weighing 421g, it's a practical, durable spotting tool for anyone working ground after dark.
