This housing was designed to hold a Canon HV-30 video camera with wide-angle converter lens. Because very high quality and wide frequency response recordings needed to be made at the same time, a MircoTrack II audio recorder was included in the housing. On the front of the housing is a Sensor Technology SQ26-06 hydrophone. The hydrophone is protected from bubble noise by a stainless steel mesh. Its lead enters the housing through an o-ring-sealed port, and goes to the audio input of the recorder. The headphone output of the recorder goes to the audio input of the camera, allowing synchronization of the two recordings. On the operator’s left side of the housing are controls for Recorder On-Off, and the Record Start/Stop button. On the right side are On/Off for the camera, and Record Start/Stop. Zoom control is on the top of the housing.

This housing was designed to hold a Digital Video Recorder on a Remote Operated Vehicle to depths of 500M. The DVR mounts on the internal tray with Velcro. The two hex bolts used for pressure testing are to be replaced by customer-supplied underwater connectors for Power and Video Input. The aluminum tube is .5 inch thick and the door is 2 inched thick.

This 500M housing was made to hold a Sony HD camera and Wide converter. It uses a dome port for best imaging without distortion. The camera is designed to be free-running during short duration dives, hence there are no controls or connectors.

This housing was designed for use with a prototype camera for photographically measuring the size and shape detail of marine artifacts while they are still in the water. The camera was not finished, so it was necessary to design and build the housing from only basic dimensions of the equipment to go into it. Fortunately, goof customer-builder communication assured that the equipment did fit. |

The standard OPT-06 housing is shown here fitted with a finely-adjustable 3-axis mount for a high speed motion analysis camera and wide angle lens. This unit will be used in pairs with grids in the background to study relative motion of reef fishes.

This latest generation lighting system uses six high-power LEDs per segment, up to 6 segments per installation, that mount on a light ring that clamps to any of the OPT series of underwater PTZ webcams. Shown mounted on OPT-05 600 ft deep housing for Sony RZ-25 PTZ webcam.

This housing is the flagship of Ocean Presence Technology’s line of underwater PTZ (Pan Zoom Tilt) webcams. It features double O-Ring bore seals between the base and cylinder, top rim and cylinder, and double o-ring face seals between the glass hyperhemisphere dome and top rim. It is rated to 180 feet [55M], and can be transmit its images by PoE Ethernet or fiber optic. See
www.oceanpresence.com for more details.

The swimmer stroke analysis video cam developed in 2006, now has cameras in three axes to make simultaneous views of a swimmer to quantify the kinematic motion of the swimmer, as part of an effort to improve the efficiency of the athlete’s stroke. The system is also used to analyze impairment of disabled swimmers as part of their aquatherapy program. Shown is one of the cameras on its adjustable mount at the University of Hawaii pool, with the program’s developer, Dr. Jan Prinz.

This housing is for a Panasonic AK-HC1500, Fujinon
HD76-137 Zoom lens, and Toshiba Protégé M400 Hi-Def
monitor, all for use in an underwater theatrical
production. It was designed to be hand-held by a
SCUBA-equipped cameraman in a huge circular tank during
the show. The monitor, used as a viewfinder by the
camera operator, is adjustable in tilt, and can be
clamped with the handle assembly at a comfortable
location along the barrel of the housing. Front and rear
doors feature double o-ring bore seals to the barrel.
The front door has a 6” dome port, which is protected by
a circular hood. The rear door has a tray inside, to
which all internal equipment is mounted, including
termination for a custom-made umbilical. The latter
cable provides power in, video out, and external
controls for all camera and lens functions, which are
controlled by operators topside. |

This is the first in a series of experimental lighting methods for attracting and illuminating sea creatures at night. The banks of high-intensity LEDs are mounted to flex circuits, which are in turn bonded to copper heat sinks. The lower banks on each side are adjustable, in order to empirically determine the best angle to provide even coverage on various subjects. |

This housing is used by a designer of fishing nets to
document how a trawl net is spreading as it is towed
through the water. The housing is rated to a depth of
1000 Meters, and is made of aluminum tube. The holes in
the rear flange are used to bolt the housing to a steel
protective cage, which is then sewn into the net
pointing to the area of interest. A free-running video
camera is wrapped in foam, inserted into the tube, and
the door secured in place. See
www.trawlcamera.com. |

| Rear view of Trawl camera housing. The quarter-turn
valve and check valve are part of the purging system.
Ambient moisture in the air inside the housing is
displaced by dry Nitrogen, which is bled in through the
quarter-turn valve and exiting through the check valve.
This procedure prevents moisture inside the housing from
condensing inside the lens port when the housing is
surrounded by very cold water. |

This housing allows use of a Fastcam APX-RS to capture animal movements at speeds of up to 3,000 frames per second at full resolution. The study examines the movements of wild jellyfish as they swim through the water. The arm assembly, shown folded, allows a laser light source to be positioned accurately and repeatably. The green laser is projected through a cylindrical lens, producing a plane of green light, through which the jellyfish swims, recording details of the movement of structures through time. These movements can be analyzed for quantification of the energy required to propel it through the water.

Classroom and hands-on pool training were made available to customer for the Dodeca Housing preparatory to taking the unit on a tour of many coral reefs in the South Pacific.
The first photo shows the housing being handed to a
diver. |
| This second shows the diver learning
to swim with the camera held steady for a full 360
degree view. |

reviewing video tapes made during the training session. |

This spherical housing was made for the Dodeca camera
from Immersive Media
www.immersivemedia.com. This
camera has eleven video cameras in a spherical shape,
and can stitch the images in real time for a full
360-degree view. This housing was designed to be
suspended underwater from a boat or to be mounted
upright on a submersible or stationary point, ad depths
down to 150 feet. The domes are acrylic and are 6"
diameter.This camera housing has now been used on the back of a surfer to provide 360 degree views of surfing that have not been possible before.

| The same housing is shown hanging from a rope. Data
cable connects to the 12-pin Impulse connector offset
from the centerline of the housing. A different mounting
plate can also mount the camera on a pole. |

This is one of a pair of housings to be used by a
swimming coach at the University of Hawaii to study and
improve the swimming motions of athletes. The Basler
high-speed camera and lens are controlled and viewed via
a FireWire connection to a computer and display on the
pool deck. One camera records the side view of the
swimmer and a second records simultaneously the front
view. The recordings, up to 4,000 frames per second, can
be used to create 3D stick figures of the swimmer, and
can be used to quantify the speed and power of each
muscle. The same systems are also used in aquatherapy to
help understand the limited motion in stroke patients. |

These photos show the latest improvements and refinements on the AquariCam, which is now rated for use in the ocean to 160 feet. It features a field-replaceable glass dome and simplified cabling. Below the housing base is an adjustable weight tray, which can also be used as a mounting base. Not shown is strain relief that protects cables entering the housing. |
|
This is the latest version of the AquariCam in
place on a rock in Kona in 2006. The new version has a
glass dome that is a greater portion of a sphere than
earlier ones. The glass should be more resistant to
biofouling than the acrylic ones. |

The housing is attached to a rock in about 25 feet of
water between the two bright lights. Snorkelers are at
the perimeter of the lighted area, divers are below, and
five manta rays are between the lights and the shore.
Dive vessel is anchored off shore. Power and Ethernet
cables are run from the camera through the intertidal
zone and up the cliff to the left of this photo. Photo
taken at about 10 PM. |
