Pixfra Draco D635-4K (640x512) Multispectral Binoculars

Craftsmanship & Construction

The Draco D635-4K is housed in a lightweight yet robust magnesium-alloy chassis, providing a durable, shock-resistant body built to withstand the rigours of field use. Its design balances portability and ruggedness, making it comfortable for extended use without sacrificing durability.

A carefully engineered layout — including a multi-function control wheel and four-button interface — mirrors traditional binocular handling while supporting precise digital controls. Foldable eyecups and ergonomically shaped housing ensure secure, comfortable handling in a variety of field conditions.

Optical & Thermal Performance

At the heart of the Draco D635-4K lies a 640×512 VOx thermal sensor with <15 mK NETD sensitivity and a 35 mm objective lens, delivering detailed thermal detection even in challenging conditions such as rain, fog or dense vegetation. Thermal magnification ranges from 2.6× up to 20.8× with a field of view of 21.9 m at 100 m, enabling secure detection of heat signatures out to impressive distances.

For visual identification, the device uses a high-resolution 1/1.8″ CMOS sensor providing 3840×2160 resolution for 4K day/night digital vision. Night vision mode includes a detachable 850/940 nm IR illuminator for extended reach in near-total darkness. A 0.49″ Full-HD OLED display and 18× ocular lens deliver immersive, sharp viewing — suitable for both two-eyed observation and long sessions in the field.

Pixfra Draco D635-4K FAQs

How does the thermal sensor perform in low-visibility conditions (fog, rain, darkness)?

The 640×512 VOx sensor with < 15 mK NETD sensitivity offers excellent thermal detection even in challenging weather. Thermal imaging remains reliable in rain or fog, enabling detection of heat signatures when optical vision is compromised. Combined with EIS and defog mode, the Draco maintains clarity even under poor visibility.

What kind of magnification and detection range can I expect?

Thermal magnification ranges from 2.6× to 20.8×, and detection ranges extend up to 1800 m — more than sufficient for long-range wildlife spotting or security surveillance. The digital night/dawn vision channel offers 5.5× to 44× magnification, useful for detailed identification once a target has been detected thermally.

Is night vision effective without ambient light?

Yes — the built-in IR illuminator (850/940 nm, detachable) extends vision in near-total darkness, making the device suitable for nocturnal observation. This works in tandem with the 4K CMOS sensor and OLED display to maintain detail and contrast even without moonlight or ambient illumination.

How accurate and useful is the laser rangefinder?

The integrated laser rangefinder can measure distances up to 1000 m, with ±1 m accuracy, giving valuable distance data whether you’re hunting, scouting or conducting security work. This feature enhances situational awareness by letting you gauge how far away a subject is — especially useful before attempting identification or tracking.

Can I record video or take snapshots with the Draco?

Yes — the device supports video recording and snapshot capture directly to the built-in 64 GB storage. It also offers Wi-Fi hotspot connectivity and can interface with the complimentary Pixfra app, allowing you to review and share footage from recorded observations.

How long does the battery last, and how is it powered?

The Draco D635-4K runs on replaceable 18650 lithium batteries (dual system), providing up to approximately 9 hours of operation depending on temperature and usage. It can also be powered via external charging — for example, using a power bank — for extended sessions in the field.

Is the Draco comfortable for extended handheld use or two-eye observation?

Yes — with adjustable interpupillary distance (60–74 mm), foldable eyecups, diopter adjustment (–5 D to +5 D) and a lightweight (magnesium-alloy) body, the device supports comfortable two-eye observation over extended periods. Its ergonomic layout and binocular-style control wheel help make long observation sessions more manageable.
