| ‘HERMES’
INTEGRAL PAN AND TILT CAMERA |
The "HERMES" is a compact
high quality television camera capable of providing a very wide angle view
of an indoor or outdoor scene, in a wide range of illumination conditions.
Its approximate "brick" shape and dimensions allow it to be covertly built
into walls and similar locations, thus making it admirably suited to discreet
surveillance applications.
The high resolution solid-state
sensor is mounted on a motorised X-Y shift mechanism to give the optical
effect of pan and tilt without the camera body moving, and in conjunction
with an ultra wide-angle lens with a large image field, this allows the
user to examine in detail any selected part of a scene with an angle of
view up to 120 degrees in both planes.
The standard unit
is based on a high resolution monochrome sensor, but a colour version will
be available shortly, in a slightly larger case.
The camera can operate over
a wide range of scene illumination, controlled by a video AGC system and
an automatic exposure control acting on the sensor's selectable exposure
time facility. This adjusts the effective exposure from l/5Oth to 1/10000th
of a second.
CONSTRUCTION
The unit is a rectangular
shape, virtually identical in size to a standard house back, with the lens
at one end and the connectors situated at the other. All the components
including the lens are completely enclosed with a glass faceplate at the
front and the unit is environmentally protected to IP55.
The Control Unit is housed
in a desk-mounting case with a sloping panel carrying the controls,.all
the connections being made at the rear.
Three sets of push buttons
respectively control the lens focus and the pan and tilt functions: the
latter may optionally be Controlled by a panel-mounted joystick. The rear
panel carries a miniature multl-way connector to control the camera functions
and supply it with power and a supply input connector. The unit operates
as standard from 12V DC at approximately 120mA, but a mains adaptor can
be suppiled if required.
An alternative mode of operation
is to control the camera with a remote control unit via a transmitter-receiver
system.
