1 Introduction
The ExCam series (type 08) is an electrical device. It is certified and approved as a pres-
sure-resistant camera system. The cameras may be used in Ex-zones 1, 2, 21 and 22,
including the explosion group IIC (for example, acetylene) and IIIC (conductive and com-
bustible dust). Some models are even approved for the mining industry.
Some models of the T08-

mobile explosion-proof camera devices (hand-held use, etc.).
