INTRODUCTION
The TORNADO low light level camera incorporated the latest innovations in CCD sensor technology.
Complemented by an auto iris lens the system approaches the performance of a SIT camera at a fraction of
the cost. A switch mode power supply board provides all the necessary voltages for the camera module.
The module is controlled internally by RS232 providing full adjustment of all the camera functions. A three
stage line driver is available to compensate for cable attenuation of the video signal.
The camera module is protected from damage in the event of accidental misconnection. A water corrected
port is fitted to optimise the picture quality. The overall package provides an extremely robust unit for use in
harsh environments.
Optional features
Stainless steel Housing 10 000psi
Customer specified connectors
OPERATING CONDITIONS
The camera is compatible with any video recorders or monitor working with PAL standard.
The camera should not be used out of the limit conditions specified in this manual. For any special
requirement please contact TRITECH INTERNATIONAL LTD.
Before attaching the connector to the camera ensure that the O’ring is on position, clean and lightly smeared
with silicon grease.
Caution!
Caution!
An internal jumper and a small potentiometer are fitted on the Long Line Driver board to give up to 3 stages
of boost to the video signal as required.
The power supply connection is polarised. Please ensure that the correct
polarity is used before switching on the unit.
Incorrect electrical connections
may seriously damage the internal electronics.
The camera is designed for use under water. Water has a cooling effect on the
camera which means that it will become hot when operated in air.
It is acceptable to run the camera in air for testing or repair purposes,
however, unless a considerable heat sink is used, it is not recommended that
the camera be left to operate in air for extended periods as the life of the
camera may be reduced.
