【Working Principle】

The camera consists of a housing, lens, and terminal block. Light from the outside environment enters the lens through a glass window, focusing on the CCD chip of the camera. The CCD camera outputs a full TV signal, converting the captured real-time image into a network video optical signal for output.

【Performance Characteristics】

1.Infrared Automatic Compensation

Features infrared automatic compensation function, capable of delivering high-quality monitoring images in low-light conditions, with a minimum illumination of ≤0.05lx and horizontal clarity of ≥400 lines.

2.Voice Intercom

The camera integrates intercom devices such as a handle and speaker, achieving integration of camera, intercom, and transmission for image monitoring and intercom at key coal mine positions.

3.Data Conversion

Converts captured real-time images into Ethernet optical signals and Ethernet electrical signals for output, offering high transmission efficiency and long transmission distances.

4.Compact Structure

The camera integrates the lens, solid-state CCD device, and wireless transmission device into a single housing, achieving integration of camera and transmission.
