Product Description
A refrigerator defogging camera is a specially designed miniature camera module for low-temperature, high-humidity environments (such as smart refrigerators and freezers). It typically uses a built-in thermistor or heat-conducting metal component to transfer the heat generated by the compressor/condenser to the lens surface, achieving automatic heating to defog/remove condensation and ensure clear images.
Core Technologies and Features:
Defogging Principle: The camera uses continuous temperature control to maintain a lens surface temperature higher than the ambient dew point, preventing condensation.
Physical Defogging: A heat-conducting metal rod connects to the freezer components, directly transferring heat to the front of the camera.
Hardware Components: Commonly uses a 1080P high-definition, wide-angle (180-degree fisheye) lens module, connected via USB, supporting night vision.
Application Scenarios: Primarily used for integrated smart refrigerators and cold chain monitoring in commercial freezers, enabling real-time inventory quantity identification.
