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

Raythink FC225T-003A004FFL-B2 Key Features

  • High Thermal Sensitivity (NETD ≤ 40mK): Detects minute temperature variations (as low as 0.04°C), ensuring crisp target silhouettes even in low-contrast, humid, or stormy environments.
  • AI Deep Learning Analytics: Features on-edge Video Content Analysis (VCA) that classifies humans and vehicles on the thermal channel, filtering out false triggers caused by foliage, small animals, weather, or lighting shifts.
  • Thermographic Temperature & Fire Monitoring: Measures target temperatures from -20°C to +550°C with an industrial accuracy of ±2°C or ±2%. Supports up to 4 concurrent measurement rules (spot, line, area, full frame) and dedicated early fire/hotspot alarm algorithms.
  • Two-Way Audio & Alarm Linkage: Equipped with 2 alarm inputs, 1 relay output, and two-way audio interfaces to link directly with external strobe lights, sirens, or perimeter access control systems.
  • Industrial Port & Outdoor Durability: Rated IP66 with an operating temperature range of -40°C to +70°C, housed in a rugged aluminum chassis with PoE (802.3af) support and up to 256GB local MicroSD edge storage.
Product Overview

The Raythink FC225T (3.2mm) is a compact, dual-spectrum IP bullet camera engineered for wide-area perimeter security, critical asset protection, and early-warning fire detection. By combining a high-sensitivity 256×192 12µm uncooled VOx thermal sensor with a crisp 5MP visible optical sensor, it provides true 24/7 visibility—penetrating total darkness, smoke, dust, and adverse coastal or misty conditions where standard cameras fail.

Lens & Optical Characteristics (Why 3.2mm Matters)

  • Ultra-Wide Situational Awareness: The fixed 3.2mm thermal lens delivers an expansive 56° horizontal field of view (FOV). This wide viewing angle is purpose-built for short- to medium-range monitoring, maximizing scene coverage while eliminating blind spots close to the camera mounting point.

  • Matched Bi-Spectrum Framing: Paired with an co-aligned 4mm visible optical lens (~82° H-FOV) and integrated 30m IR illumination, the camera allows seamless Bi-Spectrum Image Fusion. Thermal signatures are overlaid directly onto sharp visual details, giving control room operators immediate situational context and positive target identification.

  • Operational Detection Capabilities (3.2mm Optic):

    • Wide-Angle Human & Vehicle Detection: Detects human heat signatures at up to ~135m and vehicle signatures at up to ~415m across a wide front.

    • Short-to-Medium VCA Coverage: Optimized for automated line-crossing and intrusion detection at ranges up to 25m–35m from the boundary.

Ideal Applications for the 3.2mm Model

  • Gate Entrances & Loading Bays: Monitoring broad vehicle and personnel access points without blind zones.

  • Perimeter Corners & Short Boundary Runs: Covering wide angles along internal fences or perimeter walls.

  • EV Charging & Battery Substations: Wide-angle, continuous radiometric thermal monitoring across charging banks to spot battery overheating or thermal runaway early.

  • Warehouses & Waste/Material Storage: Fire prevention and hotspot monitoring across large indoor or open-bay storage yards.
