The Pixfra DRACO D635-4K Multispectral Binoculars represent the flagship of the Draco series, delivering a powerful all-in-one observation solution for demanding users. Designed for wildlife observation, hunting, security and long-range surveillance, this premium binocular seamlessly combines thermal imaging, 4K digital day/night vision, a built-in laser rangefinder, and infrared illumination in a single, rugged handheld device.
At its core is a 640×512 VOx thermal sensor with 12 µm pixel pitch and ≤15 mK NETD, paired with a 35 mm f/1.0 lens. This combination delivers exceptional thermal contrast and fine detail, allowing subtle heat differences to be resolved even in rain, fog or dense vegetation, with reliable detection distances of up to 1800 m. Thermal magnification ranges from 2.5× to 20×, making the D635 equally capable of wide-area scanning and long-range identification.
For visual detail and identification, the D635-4K features a 4K UHD digital sensor (3840×2160) that provides sharp daytime imagery and highly detailed night vision. In darkness, the supplied 850 nm detachable IR illuminator extends viewing range while maintaining excellent clarity; a 940 nm IR illuminator is available separately for users requiring maximum discretion. Automatic day/night switching ensures smooth transitions as light conditions change, allowing you to stay focused on the observation rather than menu settings.
Images from both channels are displayed on a 0.49-inch Full HD OLED screen with an 18× ocular lens, creating an immersive two-eye viewing experience with excellent field of view. Pixfra’s PIPS 3.0 AI image processing enhances sharpness, reduces noise and optimises contrast across both thermal and digital modes, while Electronic Image Stabilisation (EIS) and defog mode maintain steady, clear viewing in challenging weather or when observing on the move.
Built around a lightweight magnesium-alloy chassis weighing just over 600 g, the Draco D635-4K balances durability with comfort for extended handheld use. Its ergonomic grip, foldable eyecups and adjustable interpupillary distance support relaxed two-eye observation, while the multi-function control wheel and four-button layout mirror traditional binocular handling for intuitive, eyes-on operation, even in darkness or with gloves.
An integrated laser rangefinder accurate to 1000 m adds precise distance measurement, enhancing situational awareness for fieldwork and long-range observation. Power is supplied by replaceable 18650 batteries, delivering up to 8–9 hours of runtime, with flexible charging options including USB-C and power banks for extended sessions. Built-in dual-band Wi-Fi, 64 GB internal storage, and video and photo recording complete a feature set designed for serious users.
For those seeking a single device that excels across day, night and thermal observation, the Pixfra DRACO D635-4K stands out as a future-proof multispectral binocular that delivers clarity, versatility and confidence in any environment.

What does “multispectral” mean on this binocular?
Multispectral means the device combines thermal imaging, digital day/night vision, infrared illumination, and a laser rangefinder in one unit. You can detect heat signatures thermally, then switch to digital vision for detailed identification.
How well does it perform in complete darkness?
In total darkness, the digital night vision works with the supplied 850 nm IR illuminator, providing clear visibility with strong detail. A 940 nm IR illuminator is available separately for more discreet use.
Is the thermal imaging good enough for long-range detection?
Yes. The high-sensitivity thermal sensor allows reliable detection of heat sources at long distances, making it suitable for open terrain, farmland, woodland edges and surveillance applications.
Can I identify targets clearly after detecting them thermally?
Yes. Thermal is used for detection, while the 4K digital channel allows precise visual identification once a target is located.
Does it work in rain, fog or poor weather?
Thermal imaging is unaffected by darkness and performs well in fog and light rain. The binocular also includes defog mode and electronic image stabilisation to maintain clarity in challenging conditions.
Is it comfortable to use for long periods?
Yes. The lightweight magnesium body, ergonomic grip, foldable eyecups and true binocular viewing make it comfortable for extended observation sessions.
How intuitive are the controls?
The multi-function control wheel and four-button layout are designed to feel like traditional binoculars, allowing easy, eyes-on operation, even in darkness or with gloves.
Does it have a built-in rangefinder?
Yes. The integrated laser rangefinder measures distances accurately up to 1000 metres, useful for situational awareness and distance assessment.
Can I record photos and videos?
Yes. You can capture photos and videos directly to the built-in internal storage, and transfer files wirelessly via Wi-Fi to a mobile device.
Can I view or stream footage on my phone?
Yes. The binocular supports dual-band Wi-Fi for stable live viewing and file access through a compatible mobile app.
How long does the battery last?
Typical runtime is around 8–9 hours, depending on temperature and usage. Batteries are replaceable, and the device can also be powered or charged via USB-C or a power bank.
Is it suitable for hunting and wildlife observation in the UK?
It is ideal for wildlife observation, surveying and monitoring. Customers should always ensure compliance with current UK laws and regulations when using night vision or thermal devices for hunting.
Is this a professional-grade device or consumer-level?
The DRACO D635-4K is a high-end, professional-grade multispectral binocular designed for serious enthusiasts and professionals who want one device capable of detection, identification and ranging.
Why would I choose this over a thermal monocular?
This binocular offers true two-eye viewing, built-in night vision, an integrated rangefinder and greater versatility, removing the need to carry multiple devices.
