Made for recording of video with synced high quality audio from a hydrophone, this housing uses a Canon Vixia HF20 video camera, a MicroTrack II audio recorder, and a C55 hydrophone, mounted on the front of the housing. The hydrophone is protected from noise impact of air bubbles by an adjustable screen that covers its active element. The hydrophone can be attached directly to the underwater connector on the front of the housing, or it can be attached to an extender cable to reduce noise by having the hydrophone located a distance away from the camera housing. The hydrophone goes through a preamplifier and then into the input of the recorder. The earphone output from the recorder is fed to the mic input of the video camera to achieve synchronization of the audio with the video. The housing has On/Off and Record Start/Stop controls for the recorder and the camera, as well as zoom for the camera. The camera can be used with either of two wide-angle adapters, and uses a dome port for distortion reduction. This housing is rated to 160 ft (48M) depth.

This housing is for a Basler A602 camera and Computar 4-8mm lens lens. Power and data are through a FireWire cable, and synchronization with other cameras is achieved by use of a 2-pin cable. The thick anodized Aluminum base weights the housing and allows it to sit on the bottom of a pool, looking upwards, and the adjustable feet and bubble level are for making the lens axis perpendicular to the water surface.
The housing is intended for a depth of 10 feet, but would work several times deeper than that. The second photo is a close-up of a novel cable passthrough that we developed for this housing, and will use again in the future.

Instead of using a mechanical PZT, this Mobotics MX-Q24M camera digitally selects a subset of its nearly hemispherical angle of view for its zoomed image. This made the housing very simple, just a base with hold-downs for the standard glass hyper-hemisphere dome. It is designed for use at up to 30M (98 ft). With a thicker base, it could go much deeper.

Using 4-inch PVC pipe and couplers, this housing has a clear acrylic door with double o-ring bore seals against the smooth inner wall of the coupler. The 316 stainless side bars hold the doors closed and provide mounting points. A connector on the rear door provides power and data through a single PoE connector. It is rated to 30 feet. Future versions will go deeper, by use of a dome port or a thicker flat port. In the photo, the housing and flat front port are shown at the left, the rear door/tray/camera is shown in the middle, and the rear view of the complete assembly is shown on the right. The customer will install the underwater PoE connector.

This is another variation of our OPT series of housings for remote controlled Pan Zoom Tilt cameras, this one is for the Sony SNC-RS44N in 1080p High Definition. Using an 8-inch diameter Schedule 40 PVC coupler as the pressure hull, the base and top rim seal with double o-ring bore seals against the inner surfaces of the coupler. The side bars hold the top and bottom together, as well as providing mounting points for weights. This housing is rated to 180 feet.

Made for recording of video with synchronized high quality audio from a hydrophone, this housing uses a Canon Vixia HG21a video camera, a MicroTrack II audio recorder, and a SQ26-06 hydrophone, mounted on the front of the housing. The hydrophone is protected from noise impact of air bubbles by an adjustable screen that covers its active element. The hydrophone has a built-in preamplifier and is attached directly into the input of the recorder. The earphone output from the recorder is fed to the mic input of the video camera to achieve synchronization of the audio with the video. The housing has On/Off and record Start/Stop controls for the recorder and the camera. The camera can be used with a wide-angle adapter, and uses a dome port for distortion reduction. This housing is rated to 160 ft (48M) depth. This housing was a rare rush order, and was completed from concept to tested housing in less than two weeks. There is a charge for such fast service. This housing was completed while I was on a trip, and was photographed by my assistant so it could be sent quickly to meet the customer’s deadline.

This housing is to be fitted to a Phantom ROV, on a custom-made tilt mechanism. It holds a Sony HF-S21 camera with a wide angle attachment, and a dome port. The camera is mounted on a tray, which is fixed to the rear door. The door has double o-ring bore seal to the inside of a 4-inch anodized Aluminum cylinder. It is rated to 500M depth. The dome is covered with stretch plastic for protection during shipping.
The second photo shows the door/tray/camera slid out of the housing cylinder.

A pair of housings were made for a project at the University of Hull in England. They are mounted as a stereo pair on a base that is lowered to the sea floor. They are made of Aluminum tube with doors on both ends. The rear door has a tray for mounting the camera, and the front door has a large flange for mounting a 4-inch dome port. Both doors have double o-ring bore seals and string closures. The cameras are free-running, and are started just before deploying the housings.

Six of these housings were made for high-speed motion analysis cameras. The housing is a variation of an ROV housing of Aluminum with flat black powder coating. The door has a tray with a mount for the Baumer camera and wide-angle lens. The door also has tapped holes for underwater connectors, shown here plugged with bolts for pressure testing. The doors were sealed with double o-ring bore seals and were held in place with string closures. These housings were used in a deep pool to observe the motion of objects as they fell through the water.

This housing was designed for a Canon HG-21 video camera, with connectors to bring power in and take video signals out. It was intended to be staked in place in stream beds in Alaska to observe salmon behavior and to count fish passing a certain point it the stream.
The external monitor can be placed on the camera for positioning, and removed for use on the bank.

This unique housing was deigned to accommodate an Impero controller for the Red video camera, used underwater. It was made from a machined an acrylic block, in a five-sided shape, with a matching door with double o-ring bore seals. It has a large knob that imitates the look and feel of the main knob on the controller, and additional controls for other functions. The connector is for an optional wired cable to the camera housing. It is designed for use up to 160 feet of depth.
