【Working Principle】

The camera consists of an intrinsically safe shell, lens, CCD, optical transmitter board, and wiring terminals. Light from the outside environment enters the lens through a glass window, focuses on the CCD chip of the camera, and the CCD camera outputs a full TV signal. This signal is then amplified and directly output as an intrinsically safe network electrical signal.

Additionally, the intrinsically safe network electrical signal enters the optical transmitter board, where it is modulated and output as an optical signal.

This optical signal can be directly output via optical fiber. The camera can clearly capture objects at a minimum illumination of 2Lux and convert the captured real-time images into optical and video signals for output.

【Performance Characteristics】

1.Longer Transmission Distance

Equipped with two 100Mbps Ethernet optical signal interfaces, it achieves a maximum transmission distance of 10km, ensuring high transmission quality and effectively solving transmission distance issues.

2.Infrared Auxiliary Lighting

With infrared auxiliary lighting, it delivers high-quality surveillance footage even in low-light conditions, adapting to the dim environment of coal mines.

3.Clearer Imaging

Captures images at a resolution of 1920×1080, achieving true 1080P HD with a horizontal clarity of up to 400TVL.

4.Easy Installation and Debugging

Pre-debugged before shipment, with the default IP address affixed to the inner wall of the casing. Simply connect the power supply and network cable or optical fiber for remote monitoring from the ground.
