COAL MINE FIBER-OPTIC EX-PROOF CAMERA is coal mine flameproof fiber
optic video camera,(hereinafter referred to as a video camera),
image uptake and transfer for downhole important
place, for containing explosive mixture of methane and other gases,
with a risk of explosion coal mine. Product performance standards
for the Q / ZMD 002-2009 "mine flameproof fiber optic video camera"
and GB15465-1995 "

Btw,I'd like to draw your attention that now all the ex-proof cameras all could work via worldwide server
like normal cameras, you can connect it whatever and 7*24hours via
cellphone and computer,also could make POE in ex-proof field, I
believe all this new technology in ex-proof could have good market.
