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.

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

7. Troubleshooting
Symptom Likely cause Remedy
Image not in focus Focal length incorrect for
application
Check original specification when purchased If focal length specified matches current application (i.e. usage has not changed since initial purchase) there may be a fault with the unit Contact Tritech International Ltd for advice, or try adjusting focus.
LEDs not adjusting to light conditions
Fault with Dynamic Light Control
Check original specification when purchased Was DLC specified to be disabled at purchase? If not contact Tritech International Ltd to arrange repair (there may be a charge if the camera is out of warranty)
LEDs not adjusting to light conditions
DLC was disabled due to manual control of the LEDs being used
Cycle power to the Super SeaSpy, leaving several seconds between switching off and switching back on.
No Video output from camera
Video line fuse has blown Check continuity of Video
line fuse. Replacing blown fuse should restore video feed.
