Thermal Monocular PIXFRA Draco PFI-225N-4K

Thermal & Digital Binocular with Laser Rangefinder

This dual-spectrum thermal and digital binocular combines high-sensitivity thermal imaging, 4K digital optics, an integrated laser rangefinder, and IR illumination, making it a versatile observation tool for both day and night use. Designed for demanding users, it delivers precise distance measurement, clear imaging, and a wide range of intelligent features in a robust housing.

High-sensitivity thermal imaging
The vanadium oxide uncooled thermal sensor with 256 × 192 resolution, 12 μm pixel pitch, and NETD ≤18 mK detects even minimal temperature differences. The fast 25 mm F0.9 lens enables detection distances of up to 1300 meters.

4K digital day observation
The digital channel offers up to 3840 × 2160 (4K) resolution, delivering sharp and detailed images in daylight. Multiple color modes and a 55 mm digital optic allow image adaptation to various lighting conditions.

Laser rangefinder & IR illumination
An integrated laser rangefinder measures distances up to 1000 m with ±1 m accuracy. The replaceable IR illuminator (850 nm or 940 nm) provides effective illumination up to 350–400 m, enabling reliable operation in complete darkness.

Advanced features
The device supports photo and video recording, Wi-Fi connectivity, GPS, electronic compass, microphone, PIP mode, hot spot tracking, and intelligent image processing technologies such as PIPS 3.0 and Smart IR.
