Introducing the New HIKMICRO HABROK 4K 2.0 HH35L Multi-Spectrum Binoculars

Thermal, 4K Digital Vision and Laser Rangefinding in One Binocular

HIKMICRO has expanded its HABROK 4K 2.0 range with the new HIKMICRO HABROK 4K 2.0 HH35L, a multi-spectrum binocular that combines thermal imaging, 4K digital observation and a 1000m laser rangefinder in one handheld device.

Built around a 384×288 thermal sensor with <15mK NETD, a 35mm F1.0 thermal lens and a 4K digital channel, the HH35L is designed to give users the flexibility to observe across changing light and weather conditions without swapping between separate devices.

Add HIKMICRO's Shutterless Imaging System (HSIS), image stabilisation, Zoom Pro and an 1800m thermal detection range, and the HH35L brings some significant technology to the HABROK 4K 2.0 family.

384×288 Thermal Imaging with <15mK Sensitivity

At the heart of the HH35L's thermal channel is a 384×288 VOx detector with a 12μm pixel pitch and 50Hz refresh rate.

Perhaps more importantly, the sensor offers a NETD of less than 15mK. A lower NETD allows the thermal system to distinguish smaller temperature differences within a scene, helping reveal finer details when thermal contrast is limited.

This is paired with a 35mm F1.0 objective lens, giving the HH35L a detection range of up to 1800 metres.

The thermal channel starts at 4.0× magnification, with digital magnification extending up to 20.0×. Its field of view measures 13.16m × 9.87m at 100m, providing a useful balance between scanning an area and observing subjects at longer distances.

HIKMICRO Shutterless Imaging System

One of the most interesting features of the HH35L is HIKMICRO's Shutterless Imaging System, or HSIS.

Conventional thermal devices periodically perform shutter-based calibration, which can cause a brief interruption to the thermal image. HSIS is designed to reduce these interruptions and provide a smoother, more continuous viewing experience.

For longer observation sessions or when following a moving subject, that uninterrupted image can make the binocular feel noticeably more natural to use.

4K Digital Observation During the Day and Night

The HH35L isn't simply a thermal binocular.

Switch to the optical channel and you have a 3840×2160 4K CMOS sensor paired with a 60mm F2.2 digital lens. The optical system provides 5.5× to 22.0× magnification and a field of view of 12.8m × 7.2m at 100m.

This gives you a conventional, detailed digital image when conditions allow, making it easier to examine features that aren't always as obvious through thermal imaging alone.

A rear toggle lever allows you to quickly move between the thermal and digital channels, so you can use thermal to detect something of interest before switching to the 4K channel for a different view of the scene.

Digital Night Vision with Replaceable IR

The digital channel isn't limited to daylight.

For night-time observation, the HABROK 4K 2.0 HH35L features Smart IR and a replaceable infrared illuminator.

A 940nm illuminator is supplied as standard, while an 850nm option can also be fitted depending on your requirements. With infrared illumination, HIKMICRO specifies a night-time viewing range of up to 400 metres.

Optical viewing modes include Day, Night, Auto, Green and Yellow, giving you several options for adapting the display to the environment.

Integrated 1000m Laser Rangefinder

Alongside its two imaging channels, the HH35L includes a built-in 905nm Class 1 laser rangefinder.

It can measure distances from 10 metres out to 1000 metres, with a stated accuracy of ±1 metre.

Integrating the LRF directly into the binocular means you can detect, observe and measure distance without having to switch to a separate rangefinding device.

Image Stabilisation and Zoom Pro

High magnification is useful for examining distant subjects, but even small movements become much more noticeable as magnification increases.

HIKMICRO has therefore equipped the HH35L with electric image stabilisation across both its thermal and digital channels, available from 2×.

This works alongside Zoom Pro, which is designed to improve the experience when using digital magnification. Together, the two features help provide a steadier and more usable image when taking a closer look at distant objects.

A Full Range of Observation Features

The HH35L also includes many of the additional tools you'd expect from HIKMICRO's latest multi-spectrum binoculars.

Picture-in-Picture (PIP) can provide a magnified section of the image while retaining the wider scene, while Hot Track can identify and follow the hottest point within the thermal image.

Users can choose between six thermal palettes: Black Hot, White Hot, Red Hot, Red Monochrome, Green Monochrome and Fusion.

There's also a digital magnetic compass, hotspot connectivity and compatibility with the HIKMICRO Sight App.

Capture What You See

For users who want to record their observations, the HABROK 4K 2.0 HH35L supports video, snapshot and audio recording.

There's 64GB of built-in eMMC storage, providing plenty of space for captured footage and images without relying on a separate memory card.

The Local Album feature also allows saved footage and photographs to be reviewed directly through the binocular.

Designed for Extended Use Outdoors

Despite combining thermal imaging, digital observation, IR illumination and laser rangefinding into a single unit, the HH35L weighs 900g without batteries.

Power comes from a replaceable rechargeable Li-ion battery, with HIKMICRO quoting at least 6.5 hours of operation at 25°C with the hotspot and LRF switched on.

USB Type-C provides another charging option and supports an external power supply for longer sessions.

The binocular itself is IP67 rated and designed to operate in temperatures ranging from -30°C to +55°C, helping make it suitable for demanding outdoor conditions throughout the year.

Other practical touches include a rear focus wheel, adjustable interpupillary distance from 60mm to 74mm and a standard 1/4"-20 mounting point for tripod use.

Where Does the HH35L Fit in the HABROK 4K 2.0 Range?

The arrival of the HH35L adds another option to HIKMICRO's expanding HABROK 4K 2.0 family.

Its combination of a 35mm thermal objective, 384×288 detector, <15mK thermal sensitivity and 1800m detection range gives it a strong emphasis on longer-distance thermal observation, while retaining the 4K digital imaging and integrated LRF that make the HABROK platform so versatile.

Rather than carrying separate thermal, digital night vision and rangefinding devices, the HH35L brings all three capabilities together in a single binocular.

HIKMICRO HABROK 4K 2.0 HH35L: Key Specifications

A New Addition to the HABROK 4K 2.0 Line-Up

The HIKMICRO HABROK 4K 2.0 HH35L brings together several technologies that would traditionally require multiple devices.

Its sensitive 384×288 thermal system provides detection out to 1800 metres, while the 4K digital channel delivers detailed daytime and night-time observation. Add a 1000m laser rangefinder, HSIS, image stabilisation and replaceable IR illumination, and the result is a highly versatile multi-spectrum binocular built for observation across a wide range of conditions.

For existing HABROK users, the HH35L also represents an interesting new position within the 4K 2.0 range, particularly for those looking for the combination of a 35mm thermal lens and <15mK thermal sensitivity.

HH35L 2.0 vs HE25L 2.0: What's the Difference?

The new HIKMICRO HABROK 4K 2.0 HH35L sits alongside the HE25L 2.0, but there are some important differences between the two models, particularly when it comes to thermal performance.

Both binoculars share a 4K 3840×2160 digital sensor, 60mm F2.2 digital lens, 1000m laser rangefinder, HSIS shutterless imaging, image stabilisation, Zoom Pro and replaceable IR illumination. The biggest changes with the HH35L are found in its thermal sensor, thermal sensitivity and objective lens.

HIKMICRO HABROK 4K 2.0 HH35L vs HE25L 2.0

A Higher-Resolution Thermal Sensor

The most significant upgrade is the move from the 256×192 thermal detector in the HE25L 2.0 to a 384×288 detector in the HH35L 2.0.

That gives the HH35L more than twice the number of thermal pixels, allowing more information to be captured within the thermal image. This becomes particularly useful when observing smaller or more distant subjects and when applying digital magnification.

Thermal sensitivity also improves from <18mK to <15mK NETD. This allows the HH35L to distinguish finer temperature differences within a scene, helping reveal additional thermal detail when conditions provide limited temperature contrast.

35mm vs 25mm Thermal Lens

The HH35L also moves from the HE25L's 25mm F1.0 thermal objective to a 35mm F1.0 lens.

Combined with the higher-resolution detector, this increases the quoted thermal detection range from 1200 metres on the HE25L to 1800 metres on the HH35L, an increase of 600 metres.

Interestingly, the HH35L achieves this while also providing a slightly wider quoted thermal field of view at 100 metres: 13.16m × 9.87m compared with 12.2m × 9.3m on the HE25L.

The 4K Digital Channel Remains Familiar

The differences become much smaller when switching away from thermal.

Both models use a 1/1.8" 3840×2160 CMOS sensor and 60mm F2.2 digital objective, providing 5.5×–22.0× magnification and a field of view of 12.8m × 7.2m at 100 metres.

Both also support Smart IR with interchangeable 940nm and 850nm illuminators, with a quoted digital night viewing range of up to 400 metres.

This means the main reason to move from the HE25L 2.0 to the HH35L 2.0 isn't the 4K digital channel. It's the additional capability of the thermal system.

Shared HABROK 4K 2.0 Technology

Elsewhere, the two binoculars are remarkably similar.

Both feature HIKMICRO's Shutterless Imaging System (HSIS) for uninterrupted thermal observation, alongside electronic image stabilisation on the thermal and digital channels and Zoom Pro for higher-magnification viewing.

You also get the same 1000m laser rangefinder with ±1m accuracy, Picture-in-Picture, Hot Track, video and audio recording, 64GB internal storage and a 1920×1080 OLED display.

Even physically, there's very little separating them. Both have the same 143.1 × 74.8 × 223.3mm dimensions, while the HH35L weighs 900g compared with 895g for the HE25L.

Which HABROK 4K 2.0 Has the Stronger Thermal Specification?

The HE25L 2.0 and HH35L 2.0 share much of the same HABROK platform, but their thermal specifications create a clear distinction between the two models.

The HE25L 2.0 combines a 256×192 detector and 25mm lens with a 1200m detection range, while retaining the 4K digital channel, LRF and core HABROK 4K 2.0 features.

The HH35L 2.0 steps up to a 384×288 detector, <15mK NETD, 35mm F1.0 lens and 1800m detection range. For users comparing the two models primarily on thermal capability, these are the specifications that set the new HH35L apart.
