Underwater Video Camera : What is it?
| Underwater video cameras are electronic devices used for capturing and recording underwater events. They function like standard video cameras and camcorders except that they have special features that enable them to be operated underwater such as depth focus, audible moisture alarms, optics and rear plates, and amphibious microphones. Underwater video cameras are commonly used for underwater exploration, checking out of dive sites, search and rescue operations, fish finding, boat hull inspection, drainage pipe and tank inspection, and underwater security purposes. |

Light sensitivity: Choose an underwater video camera with superb light sensitivity for long range viewing, ambient light operation, and use in turbid water conditions.
Lens: For underwater navigation, look for an underwater video camera with a wide-angled lens for a wider coverage of large areas at close range and a good depth of field without the need to adjust focus. |
