The water pressure requirements for underwater aquaculture cameras in offshore cage aquaculture usually depend on the water depth of the breeding area. Generally, within the water depth range of 10 meters to 50 meters, the corresponding water pressure requirement is about 100 kilopascals to 500 kilopascals.

According to relevant standards and actual aquaculture conditions, ordinary nearshore cages are usually set in sea areas with a water depth of less than 15 meters, while deep-water cages are placed in open and semi-open sea areas with a water depth of more than 15 meters. The low-tide water depth for offshore aquaculture is generally 20 meters to 50 meters. For example, an underwater monitor developed in a study for deep-water cage aquaculture can withstand a water depth of up to 50 meters. In addition, underwater cameras usually need to reach an IP68 or higher protection level to ensure normal operation in the corresponding water pressure environment.
