HIKMICRO Habrok 4K 2.0 HH35L Thermal & Digital Binoculars with LRF

The HH35L 2.0 incorporates a 384 × 288 thermal detector with 12µm pixel pitch, a 35mm F1.0 objective lens and thermal sensitivity below 15mK.

This combination provides improved temperature differentiation and image detail in demanding observation conditions, helping users locate animals and other heat sources against complex backgrounds.

The thermal channel operates at 50Hz for smooth moving imagery and offers a detection range of up to 1,800m under the manufacturer's test conditions.

Thermal magnification ranges from 4.0× to 20.0×, allowing users to scan an area and progressively enlarge distant subjects.

The available thermal palettes include White Hot, Black Hot, Red Hot, Red Monochrome, Green Monochrome and Fusion.

Importantly, the quoted 1,800m range is a detection figure rather than a guarantee that an animal or object can be positively identified at that distance. Identification range depends on the target, conditions and viewing environment.

Alongside its thermal detector, the Habrok features a dedicated 3840 × 2160 digital imaging sensor with a 60mm F2.2 objective lens.

This optical channel provides detailed daytime imagery and infrared-assisted viewing after dark, making it useful when users want to observe physical features that cannot be distinguished through thermal imaging alone.

The digital channel offers magnification from 5.5× to 22.0× and supports day, night and automatic viewing modes.

With suitable infrared illumination, the manufacturer quotes a night viewing distance of up to 400m. Actual performance will vary according to the illuminator, environmental conditions and target reflectivity.

The binoculars allow users to switch between thermal detection and digital observation using the rear control, reducing the need to change equipment during use.

The integrated laser rangefinder measures distances from approximately 10m to 1,000m, with a stated accuracy of ±1m.

This allows users to establish distances while observing through the binoculars without switching to a separate rangefinding device.

Maximum range	1,000m
Minimum range	10m
Measurement accuracy	±1m
Laser wavelength	905nm
Laser classification	Class 1

The binoculars also support ballistic calculation functionality, subject to correct configuration and the applicable device settings.

HSIS Shutterless Technology

HIKMICRO Shutterless Image System technology helps maintain continuous thermal viewing without the familiar image freeze associated with conventional shutter-based calibration.

Image Pro 3

Advanced image processing enhances perceived detail, contrast and image clarity to make observation more comfortable across varying conditions.

Electronic Image Stabilisation

Image stabilisation is supported in both thermal and digital channels, helping reduce visible movement when using higher magnification settings.

Picture-in-Picture

Picture-in-Picture allows an enlarged section of the image to be viewed while retaining awareness of the wider scene.

Rear Focus Control

The rear-mounted focus wheel provides convenient focusing while the binoculars remain in a natural viewing position.

Photo and Video Recording

Capture photographs, video and audio recordings using the built-in 64GB storage.

Wireless Connectivity

Wi-Fi hotspot functionality enables compatible connection with the HIKMICRO Sight App for supported viewing, media and device functions.

The HIKMICRO Habrok 4K 2.0 HH35L uses replaceable rechargeable 18650 lithium-ion batteries.

Four 18650 batteries are included in the manufacturer's standard package, providing two pairs. The binoculars operate using two batteries at a time, so the second pair can be carried as spares.

Battery type	Rechargeable 18650 lithium-ion
Batteries included	Yes – 4 batteries
Batteries used at once	2
Spare batteries supplied	2
Battery charger included	Yes
USB-C cable included	Yes
Stated operating time	Approximately 6.5 hours per pair
External power	5V DC, 2A USB power supply supported
Direct charging	Supported

The manufacturer's stated operating time is approximately 6.5 hours at 25°C with the laser rangefinder and Wi-Fi hotspot enabled. Actual runtime depends on temperature, display settings, operating mode and feature usage.

With two complete pairs of batteries included, users can replace the first pair when depleted and continue observing. Combined runtime will vary according to operating conditions.

The included external battery charger allows the supplied rechargeable batteries to be charged separately from the binoculars.

Only use suitable rechargeable batteries that meet HIKMICRO's specifications and follow the manufacturer's battery handling and charging instructions.

The Habrok 4K 2.0 HH35L features a removable infrared illuminator for digital night vision observation.

The standard package includes a 940nm illuminator fitted to the device and an interchangeable 850nm illuminator.

940nm infrared: Produces a less visible glow, making it particularly useful when discretion is important. It is generally better suited to observing light-sensitive wildlife at closer practical distances.

850nm infrared: Generally provides stronger effective illumination for longer-range digital night vision, although the emitter may produce a faint visible red glow.

These illuminators assist the digital night vision channel. The thermal channel detects heat signatures and does not require infrared illumination to operate in darkness.

The HE25L 2.0 is a capable option for users who want combined thermal and 4K digital viewing at a lower price point.

The HH35L 2.0 is better suited to users who prioritise thermal detail, temperature sensitivity and longer-distance detection. Its 384 × 288 detector contains more than twice as many thermal pixels as the 256 × 192 HE25L 2.0 detector.

Both models retain the versatility of digital day and night viewing, integrated rangefinding and interchangeable rechargeable batteries.

Choose the HE25L 2.0 if:

• You want a more affordable entry into combined thermal and 4K digital binoculars.
• Most observation takes place at shorter or moderate distances.
• You value the convenience of thermal detection and digital viewing in one device.

Choose the HH35L 2.0 if:

• You want a more detailed 384 × 288 thermal image.
• You regularly scan open countryside, woodland edges or longer distances.
• Improved thermal sensitivity is important in challenging conditions.
• You want up to 1,800m thermal detection alongside 4K digital observation.

For users who regularly rely on thermal imaging rather than using it only occasionally, the HH35L 2.0 provides a meaningful upgrade over the HE25L 2.0.
