HIKMICRO Habrok 4K 2.0 HH35L Thermal and Optical Binoculars

384 x 288 thermal sensor with sub-15mK sensitivity

The HH35L pairs a 384 x 288 thermal detector with a 12µm pixel pitch, sub-15mK NETD sensitivity and a 35mm f1.0 lens. When small temperature differences exist across a subject or its surroundings, the sensitive detector separates those differences more clearly rather than merging them into similar tones. This is especially useful when vegetation, mist, or low thermal contrast makes a heat source harder to distinguish. The thermal channel provides 4x to 20x magnification and a detection distance of up to 1800m.

4K digital viewing with rear thermal/digital toggle

Alongside the thermal system, these binoculars feature a 3840 x 2160 4K CMOS sensor with a 60mm f2.2 lens and 5.5x to 22x magnification. Once you have located something through thermal imaging, the rear thermal/digital toggle lets you switch directly to the optical channel so you can inspect visible detail without reaching for another device. The rear focus wheel is also close to your natural hand position, reducing the need to reposition while looking through the eyepieces. At night, the replaceable IR illuminator supports digital viewing, with both 940nm and 850nm units supplied.

HSIS shutterless thermal viewing

HIKMICRO’s HSIS shutterless imaging system removes the image freezes normally associated with shutter-based thermal calibration. Rather than interrupting the view while the device recalibrates, HSIS keeps the thermal image running continuously. When following a moving subject, you can keep watching its direction and position instead of losing sight of it during a calibration pause. Image Pro 3 processing works alongside the thermal system to manage detail, contrast and image noise, for clearer viewing across various environments.

Laser Rangefinder, PIP and image stabilisation

The integrated Class 1 laser rangefinder measures from 10m to 1000m with an accuracy of ±1m, putting a distance reading into the same binocular rather than requiring a separate rangefinder. Picture-in-Picture keeps the wider scene visible while placing a magnified view within the display, making it easier to examine a distant subject without losing its position relative to the surroundings. Electric image stabilisation operates across both thermal and digital channels from 2x magnification, counteracting hand movement as magnification makes small movements increasingly visible.

Replaceable battery and IP67 weather protection

The HH35L weighs 900g without batteries and uses a magnesium construction with IP67 protection. The housing resists dust and water, while the specified operating range of -30°C to +55°C covers a wide outdoor temperature range. A replaceable rechargeable 18650 Li-ion battery provides at least 6.5 hours of operation at 25°C with the laser rangefinder and hotspot active. The binocular also supports external power and direct charging through its 5V USB-C connection.

Full HD OLED display and 64GB recording

A 0.49-inch OLED display provides a 1920 x 1080 viewing image, with dioptre adjustment from -5D to +5D and interpupillary adjustment from 60mm to 74mm. The HH35L can record video, still images and audio to its 64GB internal storage, so observations can be retained without adding a memory card. Wireless connection to the HIKMICRO Sight App provides live viewing, media capture, settings adjustment and sharing through a compatible smartphone or tablet.
