monitor to view the picture. There are no other adjustments on the camera itself
apart from pointing the camera in the required direction using the pan and tilt.
The iCAM100 does not require manual focusing, however it should be

the field of view.
The primary function of the camera is to provide video surveillance monitoring in
classified hazardous areas, this is achieved by housing the camera electronics in
an Ex de approved enclosure.
When power is applied to the camera it turns ON and immediately begins video
transmission.
