GardePro M21 Thermal Monocular

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.

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).

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.

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.

Thermal monoculars detect heat signatures, making them ideal for nighttime activities like animal tracking. For daytime use, switch to white-hot or black-hot color modes to improve contrast in sunlit environments.
