There are a variety of underwater vehicle or ROV camera systems and the one you use will depend on the specific application you need it for. Some systems are great for high contrast and low light while others are ideal for high resolution recording and documentation. Other factors that come into play are also the conditions under which the ROV and video system are operating and the electrical resources of the vessel.
The location of your camera as well as how it moves is critical for capturing good video. You should have a full field of view, clear working area for the camera, overlapping views with other cameras, and the ability to look behind the ROVs. Ideally, the operator will need a live feed to a television so they can determine where the camera is pointing.
The latest ROV systems are capable of carrying about 10 television cameras at one time. This allows the operator to manipulate 5 or more at one time. Advancements in fiber-optic technology allows operators to transmit video data from multiple cameras to one monitor.
Many operators have begun using closed circuit systems which allows them to see real time feedback on what they are viewing. This is crucial for operators to work more efficiently out in the field. Frame freezing or grabbing technology allows operators to capture hard copies of a video image for closer examination.
No matter what camera system you are leveraging today, having the right equipment is essential for efficient underwater video work. Other factors such as fuel, weather, man power, and monetary resources all play a crucial role in how effective a video system is or is not. Advanced designs in video components and technology allow divers, boat operators, scientists, and amateur explorers the freedom to film at great depths without sacrificing time or safety.
