The Pixfra Sirius PFI-SA50 is a high-performance thermal monocular built around a massive 1280 x 1024 resolution sensor. Unlike standard 640-pixel units, this ultra-high-definition detector provides significantly more data points, resulting in a cleaner image with less pixelation when using digital zoom. This resolution is paired with a 50mm F1.0 objective lens, allowing for a 2600m detection range, making it highly effective for long-range observation in open South African terrain.

At 544g, the device is notably lightweight for its size, utilizing a carbon fibre reinforced chassis that balances durability with portability. The viewing experience is centered on a large 1920 x 1080 Full HD OLED display. This high-resolution screen ensures that the detail captured by the 1280 sensor is fully utilized, providing deep contrast and sharp target edges. While many high-end units now reach sub-20mk sensitivity, the SA50’s 18mk NETD rating ensures reliable performance in humid or low-contrast environments, maintaining a clear distinction between the target and the background.

Operational efficiency is managed via a replaceable 18650 battery system. This design is preferred by professional users as it allows for instant power swaps in the field, removing the need for internal charging downtime. The unit includes 64GB of internal storage for high-definition video recording and is IP67 rated for protection against heavy rain and dust.
