Mining camera
* Applicable to Zone 1 atmosphere especially for mine
* Built-in ultra-low illumination camera and lens
DESCRIPTION
KBA8 Mining Explosion-proof camera is designed for use in Zone1 atmosphere such as gas group-( typical gas vapours: methane and mash gas etc.) as well as underground parts of mines in need of surveillance. Infrared lamp could be equipped inside to meet the requirement of surveillance under the mine of low illumination. The camera adopts optical transceiver, CCD components, tight shot, electric zoom lens and pilot signal transmitted by optical fiber cable.
