What do these specs mean?

Understanding Thermal Specs

Thermal Resolution

Think of this like a TV screen (e.g., 1280x1024). A higher number means more pixels. More pixels give you a sharper, more detailed image, allowing you to digitally zoom in much further before the image gets blurry or pixelated.

Thermal Lens

Similar to a camera lens, measured in millimeters (e.g., 50mm). A larger lens gathers more thermal energy and "sees" further, giving you a longer detection range. However, larger lenses typically result in a narrower field of view.

Pixel Interval (Pitch)

The physical distance between pixels on the sensor, measured in microns (e.g., 12µm). A smaller number means the pixels are packed tighter together, which produces a crisper image and extends your optical magnification without needing a massive lens.

NETD (Thermal Sensitivity)

Measures how tiny of a temperature difference the device can detect. Lower is better (e.g., < 15mK beats < 25mK). A lower NETD means you get a much clearer picture in terrible weather (rain, thick fog, high humidity) and superior contrast between the animal and its surroundings.

Thermal FOV (Field of View)

How wide of an area you can see at once. A wider FOV is excellent for scanning large areas quickly to spot movement. A narrower FOV usually means the device has higher magnification, perfect for identifying specific targets at long distances.

Understanding the Math

We believe in honest, real-world field specifications.

Detection ranges are calculated by taking the manufacturer's baseline testing and physically scaling it to the average height of the target animal.

Recognition & Identification are calculated using Johnson's Criteria—the military standard for thermal optics. By analyzing the physical properties of the camera's lens and sensor pitch, we calculate exactly when the target will take up enough pixels on your screen to be clearly identified.

Note: High humidity, thick coats, and environmental background temperatures will reduce these maximum optical distances in the field.
Key Features & Highlights

Nocpix Lumi H35R Key Features

  • Elite 640x512 Thermal Resolution: Equipped with a high-definition 12µm sensor that provides superior image detail and a wider field of view compared to standard 384-resolution units.
  • Industry-Leading Sensitivity (≤18mK NETD): Extremely high thermal sensitivity allows the unit to distinguish minute temperature differences, ensuring clear imagery in challenging South African conditions like thick fog, rain, or high humidity.
  • Integrated 800m Laser Rangefinder (LRF): Provides instant and precise distance measurements to your target, eliminating guesswork during night-time predator control or ethical hunting.
  • "Fast" F0.9 Objective Lens: The large aperture allows significantly more infrared radiation to reach the sensor than standard F1.0 lenses, resulting in a brighter, higher-contrast image even in total darkness.
  • Ultra-Lightweight & Compact: Weighing only 375g, the H35R is designed for maximum portability, fitting easily into a jacket pocket for all-night treks.
  • Replaceable 18650 Battery System: Features a user-swappable battery design, allowing you to carry spares and stay in the field indefinitely without waiting for an internal charge.
  • High-Resolution 1024x768 AMOLED Display: A vivid, high-contrast internal screen that delivers deep blacks and crisp thermal signatures for comfortable, long-duration observation.
  • 1800m Detection Range: Powerful enough to detect a human-sized heat signature at nearly 2 kilometres, providing exceptional situational awareness.
  • Rugged IP67 Waterproof Rating: Built to withstand the harshest environments, the unit is fully protected against dust and heavy rain.
  • N-LINK Connectivity: Built-in Wi-Fi and app support for real-time streaming, photo capturing, and video recording with audio directly to your smartphone.
  • 4-Year Local Warranty: Supported by Cape Thermal with a 3+1 year warranty for peace of mind and long-term reliability.Nocpix Lumi H35R Key Features

Product Overview

The Professional’s Compact Choice: 640-Resolution Performance

The Nocpix Lumi H35R is the flagship of the compact Lumi series, engineered for those who demand elite thermal clarity without the bulk of a full-sized scanner. While maintaining a pocket-sized form factor of just 375g, it houses a high-definition 640x512 @ 12µm thermal sensor. This resolution jump provides significantly more detail at distance and a wider field of view, making it the premier choice for professional trackers and security operators in South Africa.

Unrivalled Sensitivity with Sub-18mK NETD

Sensitivity is the heartbeat of a thermal optic. The Lumi H35R features an industry-leading sub-18mK NETD, allowing it to detect minute temperature variances that other units miss. Whether you are operating in the thick mist of the Midlands or the dusty heat of the Karoo, the H35R cuts through environmental noise to deliver a sharp, high-contrast image on its 1024x768 AMOLED display.

Integrated Precision: 800m Laser Rangefinder (LRF)

Range estimation at night is notoriously difficult. The H35R solves this with an integrated 800m Laser Rangefinder, providing instant, accurate data for ethical predator control and tactical awareness. Combined with a "fast" F0.9 objective lens, the unit ensures maximum light (infrared) transmission for a detection range of up to 1800m.

Rugged, Reliable, and Field-Ready

Designed for the rigours of the South African bush, the Lumi H35R features:

  • Replaceable 18650 Battery System: Never let a flat battery end your night; swap power cells in seconds.

  • IP67 Waterproof Rating: Fully protected against heavy rain and dust.

  • Ergonomic Portability: Fits easily into a jacket pocket or a standard chest rig.
