Coal mine intrinsically safe network camera has the characteristics of Ethernet electrical signal output and Ethernet optical signal output. Users can choose the output method according to their actual situation. The equipment has the advantages of low illumination, high definition and long transmission distance, and is suitable for environments containing coal dust and methane explosive mixtures. Aliases: Coal mine intrinsically safe camera, mine intrinsically safe camera, mine intrinsically safe infrared camera.

Working principle and structural characteristics：

   The product consists of a camera, a photoelectric conversion board, and a power/network isolation board. When the product is working, the associated intrinsically safe power supply provides 11-16VDC working power to the camera. The camera inputs the live real-time image into the photoelectric converter through the network electrical port, and the photoelectric converter outputs the TCP/IP protocol optical signal through the transmission medium Delivered to end equipment。

  a) Rated operating voltage：DC 12V；

  b) Working current：≤0.95A；

Transmission mode：

① Ethernet interface：

  a) Transmission mode：TCP/IP protocol electrical signal transmission；

  b) Transmission rate：100Mbps；

② Fast Ethernet optical port：

  a) Interface Type：SC；

  b) Transmission mode： TCP/IP protocol optical signal transmission；

  c) Transmission rate：100Mbps。

Function：

  a) The object can be seen clearly under the minimum ambient illumination of 0.05Lux (with auxiliary infrared illumination)。

  b) With the function of optical fiber network hub, it can connect with other camera optical ports and upload images。

  c) The collected image can be converted into Ethernet optical signal or Ethernet electrical signal output。
