The editor takes you to understand the wide range of underwater camera applications
Underwater cameras are mainly used to capture underwater images. The camera can be directly used in water through waterproof treatment, and the photographer can operate the camera from the ship. The image signal is transmitted to the monitor through a cable and recorded on a magnetic tape. Due to the weak light at the bottom of the water, multiple infrared light emitting diodes are generally installed around the camera, ensuring its normal operation.
1、 Characteristics of underwater cameras
Underwater cameras have low illumination, large field of view, clear images, wide dynamic range, and outstanding features such as small size, light weight, low power consumption, technical means, high reliability, durability, and easy operation. They also have strict waterproof measures.
2、 Application Fields of Underwater Cameras
Underwater cameras are mainly used for monitoring underwater operations and have been applied in the following fields:
（1） Marine civil engineering: preliminary investigation of the reef and seabed conditions, engineering management, inspection of completion status, and serving as auxiliary equipment for underwater operations such as underwater bulldozers.
（2） Investigation and observation of water resources, investigation and research of seabed minerals, seabed oil fields, pearls, corals, and various seaweed.
（3） Fishery: survey of the actual situation of the fishnet and Artificial reef set up in a specific water area, and detection of fish stocks.
（4） Investigation of the sunken ship, monitoring of the salvage process, and inspection and valuation of the underwater parts of the ship that require repair.
（5） Supervision of underwater sludge in hydroelectric power generation and internal inspection and welding of water supply pipelines in power plants.
（6） Supervision of river and reservoir embankments and regular inspections of other underwater construction facilities.
（7） Submarine underwater reconnaissance.
（8） On site monitoring equipment for nuclear power plants.
New research data shows that the use of a new underwater television camera system for photography has achieved a maximum visible distance of over 45 meters underwater, and can be widely used in the exploration of marine and terrestrial water resources, aquaculture, underwater exploration, construction and monitoring of underwater facilities, underwater restoration, underwater sightseeing, sunken ship salvage, and oil field operations.
