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.

Product Overview

The Raythink FC225T-007A008FFL-B2 is a mid-range, dual-spectrum IP bullet camera engineered for targeted perimeter surveillance, critical infrastructure protection, and industrial fire prevention. Combining a 256×192 12µm VOx thermal sensor with a crisp 5MP optical sensor, this model replaces wide-angle distortion with focused optical reach. It delivers dependable 24/7 detection through complete darkness, dense smoke, mist, and adverse outdoor conditions.

Optical Performance & Mid-Range Field of View

  • Focused Perimeter Coverage: Featuring a 7mm thermal lens with a 24.8° × 18.7° field of view, this camera narrows scene width to maximize pixel density at distance, eliminating the edge distortion of wide-angle units.

  • Matched Bi-Spectrum Framing: Paired with an 8mm visible lens (39° × 29° FOV) and 30m IR illumination, it enables real-time Bi-Spectrum Image Fusion. Thermal heat signatures overlay onto high-definition 5MP optical streams, giving control room operators immediate visual verification and contextual clarity.

Ideal Applications

  • Long Perimeter Corridors & Fence Lines: Securing linear industrial boundaries and transport corridors where wide-angle lenses lose target resolution.

  • Electrical Substations & Distribution Yards: Identifying hot-spots and transformer anomalies from safe stand-off distances up to ~194m.

  • Industrial Material Storage & Processing: Early-stage smolder and fire detection across large yards, timber piles, and coal or waste facilities.
