Once the iCAM100 is wired up all the unit requires is power and a suitable 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 remembered that the
optimal focal distance is dependent upon the lens used for the field of view.
The primary function of the camera is to provide video surveillance monitoring in classified
hazardous areas, such as Zone 1. This is achieved by housing the camera electronics in an
ATEX certified enclosure.
When power is applied to the camera it turns ON and immediately begins video transmission.
4.1 CCTV Colour Camera
The CCTV camera is a self-contained unit with integrated fixed focal length optical lens,
imaging sensor, automatic IRIS and video image generator.
4.1.1 Power Supply Unit
The power supply converts a nominal 24Vdc into two voltage supplies (+/-9Vdc) used
internally to energise the CCTV Colour Camera and Video Line Driver; all supplies have a
common ground (GND) connection.
4.1.2 Video Line Driver
The video line driver converts the 1V composite video output from the CCTV Camera into a
2V differential composite video signal (balanced line) suitable for transmission over either a
75R coaxial cable or 150R twisted pair cable.
