The camera uses Tamron lens, with high resolution, clear and delicate images. It has ultra-low illumination and automatic color-to-black function, which enables day and night monitoring. It has a series of advantages such as small size, light weight, low illumination requirement, high clarity, and good anti-interference. It is suitable for coal mines with explosive mixed gases such as methane and coal dust. It can transmit the collected signals to the monitoring equipment through coaxial cable or optical cable, providing good technical support for timely handling of accident hazards and analysis of accident causes in coal mines.
