The 12 V dc power inlet connector, the data connector for the pan and tilt
control and the fiber optic connectors for the video and control signals, all
enter the case via the rear panel.
Camera
The camera is not accessible. The standard camera is a color video
camera but monochrome cameras can be provided. Cameras are
available for PAL and NTSC operation and may be specified with either
6:1 or 10:1 zoom lens. All required features must be specified when
ordering.
Interface Printed Circuit Board (PCB)
The PCB is not accessible. The PCB converts the optical control signals
from the VCU to electrical signals and de-multiplexes the control signals
to operate the camera lens functions (zoom, focus and iris) and also the
movement of the Pan and Tilt Head. The PCB also provides video-to-
optical conversion of the signal from the camera for application to the
VCU.
Pan and Tilt Head
The pan and tilt head electronic circuit and mechanisms are housed in a
shielded aluminum case. A screened 5-way connector enables the head
unit to be linked to the interface PCB in the shielded camera assembly
which supplies the pan and tilt signals from the joystick (or four
pushbuttons) on the VCU. External limit switches are provided for both
pan and tilt functions.
When the pan and tilt head has been specified for mounting on the
ceiling or wall of a chamber it is fitted with a circular base flange with four
6mm diameter holes. When it has been specified to be mounted on a
non-metallic tripod, it is fitted with a single mounting point for direct
connection to the tripod.
VIDEO CONTROL UNIT (VCU)
The VCU provides manual control of all the camera functions (zoom,
focus and iris) using push-buttons, and the operation of the pan and tilt
head using a joystick (or four pushbuttons).
