1. Introduction
The Super SeaSpy underwater video camera is a compact, high resolution,
full colour camera with integral low voltage lighting. It is built to survive in
the harsh underwater inspection environment and has been designed to be
compact, rugged and provide a high quality colour picture.
The camera has an integrated ring of white LEDs providing uniform
illumination across the viewing area. A sensor is incorporated into the camera
face which provides feedback to control the lighting intensity so optimum
picture quality is achieved regardless of the reflectivity of the work surfaces.
The light can also be adjusted manually if required. To prevent damage from
warm environments the LEDs also incorporate an automatic thermal cut-out.
The Super SeaSpy has an internal focus adjustment which allows the focal
range to be factory set at values between 50mm and infinity. The camera
power supply provides excellent protection for the efficient operation of the
camera module. Fitted with an integral video line driver the Super SeaSpy
compensates attenuation of the video signal when used over various umbilical
lengths. This line driver is adjustable and is protected against over-voltage.
A water corrected port is fitted to optimise the picture quality. This water
corrected view port results in a camera that provides a crisp picture during
close proximity viewing in murky water.

• High resolution colour CCD sensor
• Standard depth rating of 4000m
• Highly resistant to shock and vibration
• Wide power supply of 12V to 48V DC

3. Installing the SeaSpy
3.1. General Guidelines
If the camera is to be used as part of an ROV setup then care should be
taken during the installation to ensure that any chance of damaging it is kept
to a minimum. While it has a very robust housing it should not be mounted in
such a manner which results in it protruding excessively from the ROV body.
If such a setup is desired a suitable guard should be considered which would
keep any chance of severe impact to a minimum.
The camera should be installed using non-metallic clamps so that any
effects of galvanic corrosion are kept to a minimum. If metallic clamps are
unavoidable they should be insulated from the camera body by means of
rubber or plastic strips of at least 3mm in thickness and extending 3mm
beyond the clamp boundary. They should also be painted or lacquered with
at least three coatings.
3.2. Test Cable Wiring
To connect the camera to a computer for testing or operation it will be
necessary to construct an appropriate test cable. The pin-out diagram for
units fitted with the Tritech 6 pin standard water block is shown in the
specification section, for any other connectors it will be necessary to refer to
the documentation that was provided with the camera to establish the correct
wiring scheme.
To connect to a computer it will be necessary to provide the camera a
minimum of three connections:
1. DC Power
2. DC Ground
3. Connection to a PC video capture card, either external or internal

4. Using the SeaSpy
4.1. Operating Conditions
The Super SeaSpy Camera is compatible with any video recorders or
monitors working with PAL or NTSC depending on the transmission standard
selected at point of sale.
The camera should not be used outside of the limit conditions specified in this
manual. For any special requirements please contact Tritech International Ltd
!
Caution
The camera has an internal temperature sensor and circuitry which
will protect it from damage due to overheating, however, it is
not recommended that the camera be operated out of water for
extended periods.
Before attaching the connector to the camera ensure that the O-ring is in
position, clean and lightly smeared with appropriate silicon grease.
!
Caution
The power supply is polarised. Ensure that the correct polarity is
used before switching on the unit. Incorrect polarity may damage
the internal electronics.
!
DO NOT STARE DIRECTLY AT THE LIGHTS
The light emitted form the camera LEDs is extremely concentrated
and may damage the eye if shined directly into it so do not stare at
the lights when the unit is operational.
4.2. Camera Characteristics
4.2.1. Focus
The Super SeaSpy is a fixed-focus camera and the focal length is factory
set. The focus can be adjusted by the user, or by returning the unit to Tritech
International Ltd for servicing. The length can be specified from 50mm to
infinity.

Using the SeaSpy Super SeaSpy Camera
0514-SOM-00001, Issue: 02 13 © Tritech International Ltd.
To alter the focus of the Super SeaSpy, carefully open the unit following
the instructions detailed in Section 5.2, “Dis-assembly and Re-assembly
procedures”.
By rotating the nuts on either side of the camera module (see Section 6.1,
“General layout”)the mounting collar will be compressed or released, affecting
the focus of the unit accordingly.
4.2.2. Dynamic Light Control (DLC)
Upon initial power up the Super Seaspy camera will start up in Dynamic Light
Control (DLC)mode. This means that the ring LED’s will react automatically
to any changes in the reflectivity of the work surface or scenery ambient light
conditions: - In darker areas the ring LED’s will brighten and the reverse in
lighter areas.
Manual control mode of the ring LED’s can be obtained by applying an
analogue voltage to the +/- LIGHT line (PIN1 on Tritech connector). See
Section 6.3, “Electronic light control” for details on the nature of the voltage
signal to be sent.
If you wish to return to DLC mode, after making a manual control input, the
camera must be switched OFF for several seconds. Upon switching ON again
the camera will revert to DLC mode.
4.2.3. Water Corrected Lens
The Super SeaSpy is fitted with an "Ivanoff Corrected" lens system which
effectively compensates for the different refractive index of water vs that of
air. This means that the picture quality is optimised through the reduction of
radial distortion and chromatic aberration.

5. Maintenance
5.1. General guidelines
After use in a marine environment the unit should be washed down with fresh
water in order to remove any salt build up.
Prior to stowing, the camera should be inspected for any signs of damage. If
the camera is damaged in any way it may be possible to fix it without replacing
the entire unit, contact Tritech International Ltd for more details and advice.
5.2. Dis-assembly and Re-assembly procedures
It may be necessary to open the Super SeaSpy in order to inspect the 'O' ring
surfaces, adjust the video amplifier, or to adjust the focus of the unit.
!
Warning
Maintenance of water integrity is the responsibility of the user.
Internal damage caused by water ingress is not covered by
product warranty unless the cause can clearly be identified as a
manufacturing defect.
To extract the main electronics of the Super SeaSpy camera perform the
following actions:
1. Unscrew the water block and disconnect it carefully
2. Extract the nylon cord fitted between the front part of the housing and the
camera body
3. Gently pull off the body, as straight as possible
4. Inspect all exposed 'O' ring surfaces and 'O' rings. If in any doubt change
the 'O' ring, clean and lightly smear with silicone grease
Re-assembly of the Super SeaSpy is completed in the reverse order. Ensure
that the water block 'O' ring is in position and that the water block is correctly
aligned with the main 6-pin DIN connector before pushing it gently back into
position.
To disassemble the water corrected port from the housing:
1. Unscrew the water block and remove it
2. Extract the nylon cord maintaining the port in position

Maintenance Super SeaSpy Camera
0514-SOM-00001, Issue: 02 15 © Tritech International Ltd.
3. Using a large nylon washer to protect the body, inject air inside the body
to a pressure of 1 bar max. The acrylic port will be dislodged by this light
pressure and removed easily
!
Caution
Take care not to over-pressure the body so as to eject the port -
and ensure that it is retained during this operation
