Retrofitting a Shielded Camera Enclosure with an Internet Protocol Camera and Testing for Radiated Immunity and Emission in a Reverberation Chamber

Shielded cameras are required to observe the device under test during an immunity test in a reverberation chamber. The camera in the reverberation chamber needs to withstand the electromagnetic field and should give a good quality of the picture in real time. In this paper, the retrofitting of an existing shielded camera enclosure with a new low-cost commercial-of-the-shelf network camera is described. The camera's communication is transduced into optical fibers using media converters. The shielded camera is tested in the large reverberation chamber of the Otto von Guericke University in Magdeburg according to the IEC 61000-4-21 for radiated immunity and emission.
