Pixfra Mile 3 M335 (384x288) Thermal Imager - 35mm

The Pixfra PFI-M335 Thermal Monocular Camera combines a 384 × 288 thermal detector, 35 mm F0.9 lens and full HD OLED display in a compact magnesium alloy body. Designed for portable thermal observation, it features PIPS 3.0 Pro technology, a detection distance of 1,800 m and a quick-change rechargeable 18650 battery.

Thermal Imaging & Display

A 12 μm vanadium oxide detector operates at 50 Hz, with thermal sensitivity of ≤15 mK NETD at F1.0. The 0.49-inch OLED display has a resolution of 1920 × 1080, with six colour palettes: White Hot, Black Hot, Iron Red, Alarm, Green Hot and Sepia.

The monocular offers 2.5× visual equivalent magnification and 1×–8× digital zoom. Manual focus accommodates viewing from a close focus distance of 2 m, while picture-in-picture and hot spot tracking add further viewing options.

Construction & Handling

The durable magnesium alloy body measures 170.5 × 52.6 × 50.5 mm and weighs no more than 310 g. A control wheel combines three functions, while the eyepiece provides dioptre adjustment from -5 D to +3 D and 15 mm eye relief.

Weather Protection & Power

IP67 protection and an operating temperature range of -30°C to +55°C support outdoor use. The quick-change 18650 lithium battery provides at least 5.5 hours of operation at 25°C with Wi-Fi switched off. Power specifications include a 5 V DC supply and USB Type-C connection.

Pixfra PFI-M335 Thermal Monocular Camera Review

The Pixfra PFI-M335 Thermal Monocular Camera brings thermal observation, recording and a full HD viewing display together in a portable format. Its combination of a 35 mm F0.9 lens, 384 × 288 detector and replaceable battery makes it a relevant option for users seeking a compact thermal monocular with integrated capture features.

Performance & Key Features

The imaging specification combines ≤15 mK NETD sensitivity at F1.0 with a 50 Hz frame rate and PIPS 3.0 Pro technology. A 1920 × 1080 OLED display presents the thermal image, although the detector resolution remains 384 × 288. Viewing options include six palettes, picture-in-picture and 1×–8× digital zoom alongside the 2.5× visual equivalent magnification. The 1,800 m detection figure should be treated as a detection distance, rather than a guarantee of identification at that range.

Build Quality & Handling

A magnesium alloy body and IP67 protection are the main durability features. At no more than 310 g and 170.5 mm long, the monocular keeps its dimensions and weight compact, while the quick-change battery design allows battery replacement during use.

Is It Easy to Use?

The three-function control wheel, adjustable dioptre and choice of automatic, semi-automatic or manual FFC calibration provide several ways to manage viewing and operation. Focus is manual, so users adjust it themselves as viewing distance changes. Built-in recording, snapshots and a local album keep image capture and review within the device.

Key Takeaways

The strongest features are the sensitive thermal detector, full HD OLED display and compact magnesium alloy construction. Recording, 64 GB storage and a quick-change battery round out a practical specification for portable thermal observation. Battery endurance is conditional: the ≥5.5-hour figure applies at 25°C with Wi-Fi off. For Uttings customers prioritising these features in a 35 mm thermal monocular, the PFI-M335 is worth considering.
