Video and audio conference photographing device

The invention relates to the field of videos and audios, in particular to a video and audio conference photographing device, which comprises a photographing module, a shielding device and a controlling and processing unit. The shielding device adopted by the invention changes the light transmitting state in a circuit control manner; therefore, power machinery and a transmission mechanism are not needed for control, and the structure is simple and the space is saved. When the shielding device in the invention is in a lightproof state, the lens of the photographing module and an optical path ofa photosensitive element can be forced to cut off so as to achieve the purpose of forcing the photographing module to stop photographing; and the situation of external leakage of images after the photographing module is invaded by malicious software or hackers can be prevented effectively. In the embodiment of the invention, in the state that the shielding device is arranged outside the photographing module, a user can ea
