Underwater cameras and lighting equipment are located outside the electronics compartment, mounted at designated locations on the equipment under test (DUT), and connected to the watertight sockets via watertight cables. The watertight sockets are then connected to a video data acquisition unit and a power-on control module inside the electronics compartment. The video data acquisition unit acquires video data from the underwater camera via an electrical connection; the power-on control module provides power to the underwater camera and lighting equipment via an electrical connection. Inside the electronics compartment, the video data acquisition unit connects to a storage module to store the video data; the battery module connects to the water pressure switch, which in turn connects to the power-on control module. The opening pressure parameter of the water pressure switch is selected based on the required camera depth of the DUT.

Specifically, the power-on control module delays according to the pre-set power-on delay parameter, and after the delay time, the power supply of the video acquisition instrument, the underwater lighting device, and the underwater camera is turned on, and the video acquisition instrument, the underwater lighting device, and the underwater camera start working. After working for a preset working time, the underwater lighting device, the underwater camera, and the video acquisition instrument are sequentially powered off, and the shooting work of the device is completed. After the test is completed, the video data recorded during the test is recovered through the mobile hard disk.
