Abstract: In order to improve accuracy and real-time of deep sea cage aquaculture surveillance, we designed a video surveillance system combining 3G wireless network with VSaaS, which realized real-time video surveillance on deep sea cage aquaculture locally and remotely.In 3G+VSaaS mode, IP cameras collected field data of deep sea cage aquaculture, which were transported, published and shared through wireless network device, meanwhile the actuators could get feedback.We introduced the working principle and design framework, explained the hardware selection principles, and then analyzed the key technology of the system.To sum up, this all directional surveillance system constructed realizes information management for deep sea cage aquaculture, which promotes aquaculture production efficiency and risk prevention ability.
