The invention provides a camera, a remote video-talking system and applications thereof. The camera includes a camera shielding shell, a bracket and a pan-tilt shielding shell, the bracket is a hollow structure, and the inner cavity of the camera shielding shell and the pan-tilt shielding shell are The inner cavity of the camera is connected through the bracket of the hollow structure; the camera shielding shell is provided with a lens, a camera main board, an optical fiber transceiver, and a first filter; the camera shielding shell is also provided with a power line hole and an optical fiber interface; The optical fiber transceiver is connected to the optical fiber interface through an optical fiber; the output end of the first filter is respectively connected to the main board of the camera and the optical fiber transceiver to supply power to it. The pan-tilt camera provided by the present invention adopts a hollow bracket to communicate with the camera casing and the pan-tilt, and the power line and the signal line can be directly connected to the pan-tilt by the camera casing via the hollow bracket, thereby realizing internal wiring, so that the whole belt pan-tilt The camera structure is very compact.
Description
technical field [0001] The invention relates to the field of electromagnetic interference, in particular to a video camera, a remote video-talking system and applications thereof. Background technique [0002] In microwave anechoic chambers, especially EMC anechoic chambers and some special test occasions, in order to monitor the test process in real time and prevent accidents, the influence of surveillance cameras on the test environment must first be resolved to ensure that the test is effective and reliable. In addition, the camera is often used in combination with multiple circuit boards. There is a large amount of electromagnetic radiation between the circuit boards, and the internal radiation source is complex. If the design is not reasonable or the area of the structural board is limited, the image signal is easily interfered by electromagnetic radiation. Secondly, the image signal of the camera itself is susceptible to radiation interference in the test environment...
