Pixfra PFI-M625 Thermal Monocular Camera Review

The Pixfra PFI-M625 Thermal Monocular Camera pairs a 640 × 512 thermal sensor with a 25 mm lens, low starting magnification and a compact body. For users seeking portable thermal observation with integrated recording, its key attractions are the generous viewing coverage, full HD OLED display and quick-change battery design.

Performance & Key Features

The 17.4° horizontal field of view covers 30.6 m at 100 m, making scene coverage a central feature of this specification. Imaging combines a 50 Hz frame rate, ≤15 mK NETD sensitivity at F1.0 and PIPS 3.0 Pro technology. The 1.2× visual equivalent magnification is complemented by 1×–8× digital zoom, while six palettes and picture-in-picture offer different viewing options. Detection distance is 1,300 m; this figure should not be treated as an identification range.

Build Quality & Handling

The magnesium alloy body, IP67 rating and -30°C to +55°C operating range provide the main durability credentials. With a length of 160 mm and net weight of no more than 290 g, the design places a clear emphasis on portability. The quick-change 18650 battery is another practical feature for users who value replaceable power.

Is It Easy to Use?

The control layout combines three functions in one wheel, supported by adjustable dioptre and a choice of automatic, semi-automatic or manual FFC calibration. Focus requires manual adjustment, with a close focus distance of 1 m. Recording, snapshots and a local album are integrated into the device, alongside 64 GB of storage.

Key Takeaways

The PFI-M625 is a strong option to consider when scene coverage, a 640 × 512 detector and compact dimensions are priorities. Its 1.2× visual equivalent magnification is modest, with additional enlargement provided by digital zoom. Battery operation is rated at at least five hours under the stated conditions of 25°C with Wi-Fi off. For Uttings customers seeking a portable thermal monocular with recording and a replaceable battery, this combination deserves consideration.
