1：What's the difference between thermal imaging and night vision devices?

Thermal imaging requires no light source, relying on the object's own heat to form an image. It can penetrate smoke, mist, and darkness, and can detect even stationary targets.

Night vision devices require either low ambient light (such as moonlight or starlight) or actively emit infrared light for illumination. They rely on light reflected from the target to form an image, and are less effective in complete darkness or when obstructed by fog.

2：What is the difference between detection range and recognition range?

Detection range: The maximum distance at which a target can be detected (e.g., sensing the presence of a heat source).

Recognition range: The maximum distance at which the target type can be clearly distinguished (e.g., distinguishing between people, vehicles, and animals).

3:What determines the viewing range of a thermal monocular?

The observation distance of a thermal monocular is primarily determined by its lens focal length - longer focal lengths (e.g., 10mm vs. 15mm) provide greater detection ranges.

4：Can thermal monoculars see through walls, glass, or fog?

Thermal monoculars can effectively penetrate fog and smoke because infrared radiation passes through these airborne particles. However, they cannot penetrate solid obstructions such as walls or glass, as these materials block infrared radiation.

5：What color modes are available for thermal imaging? What are their uses?

White heat (hot areas appear white) and black heat (hot areas appear black): Suitable for quickly identifying heat sources.

Pseudo-color modes such as red heat, green heat, and iron red: Enhance image depth and facilitate differentiation between different temperature zones (such as targets in complex environments).
