摘要
The present invention relates to a power supply system for video cameras (2) and for protection cases (1) for video cameras. The system comprises a first device (13), called as powered device since it receives power from a remote device, able to split a supply voltage (131) and a data signal (130) from a power supply input line (18). A plurality of power supply lines (14a-14e) are connected to a first output of the powered device (13) and they supply a plurality of electric components (7,8,9,10) via the supply voltage (131) extracted by the powered device (13). The system further comprises a power supply equipment (19) connected to the powered device (13) so as to receive as input the supply voltage and the data signal split by the powered device. A case and a method for powering a video camera are also described.
