Nocpix Lumi H35R Thermal Monocular

The Nocpix LUMI H35R is a handheld thermal monocular for watching deer and other wildlife at dawn, dusk and after dark. It pairs a 640 × 512 thermal sensor with a built-in laser rangefinder, so you can scan a field edge and check how far away an animal is with one device.

Viewing wildlife and measuring distance

The UK model uses a 640 × 512 VOx sensor with 12 µm pixels and ≤18 mK thermal sensitivity and a 50 Hz sensor frame rate. The eyepiece has a 1024 × 768 AMOLED display. The 35 mm f/0.9 lens gives 2.5× base magnification, with up to 20× available, and a 12.5° × 9.4° field of view covering 22 × 16 m at 100 m. Electronic image stabilisation helps keep the handheld view steady. The Nocpix LUMI H35R offers selectable thermal colour palettes and quiet buttons for handheld wildlife viewing.

Two distances are worth knowing. Nocpix rates thermal detection at up to 1,800 m using a 1.7 × 0.5 m test object, and the built-in laser measures up to 800 m. Recognition depends on the subject, image detail and conditions, and fog or rain can reduce usable range.

The 25-second clip below was recorded on the H35R and shows a deer at the 2.5× base magnification.

Comparing the H35R, H35 and L35R

• LUMI H35R pairs the 640 × 512 sensor and 22 m width at 100 m with laser ranging up to 800 m.
• The Nocpix LUMI H35 wildlife thermal monocular shares the 640 × 512 sensor and 22 m width at 100 m, without an integrated laser rangefinder.
• The Nocpix LUMI L35R wildlife thermal monocular has a 384 × 288 sensor, 4× base magnification, a 13 × 10 m view at 100 m and 800 m laser ranging.

Power, recordings and box contents

Power

The H35R runs on one replaceable 18650 cell at a time and has no built-in battery. Nocpix quotes up to 4.5 hours per cell from a 22°C test with Wi-Fi and the rangefinder switched off. Charge removed cells in the charger. A separate 5 V USB-C power source can also run the unit. The H35R itself accepts a compatible cell inserted in either orientation. Its replacement battery model is the Nocpix IRB-2.

Recordings

Onboard video with audio is saved to 32 GB of on-device storage. Copy files over USB-C or use the Nocpix app. Once it’s paired over Wi-Fi, you can also use the app to control the monocular.

H35R questions answered

How long does the battery last?

Up to 4.5 hours with one 18650 cell, based on a 22°C test with Wi-Fi and the rangefinder off. Swap in a charged spare cell to keep going.

What ranging modes does the laser offer?

A single reading gives one distance measurement, while continuous readings keep updating. The laser measures up to 800 m.

How do I export recordings?

Copy video from the 32 GB on-device storage using USB-C file transfer, or use the Nocpix app.

Can I use it in wet weather?

Yes, the H35R is rated IP67. Fog and rain can still reduce usable thermal range.

How do I focus the image?

Use the objective focus to sharpen the scene, then set the eyepiece dioptre so the display looks crisp to your eye.
