Indirect Measurement of Shielding Effectiveness of an Enclosure for a Security Camera

Abstract This paper presents the results of our experiment, which consisted in measurement shielding effectiveness a camera enclosure that was designed and constructed order to increase susceptibility against external electromagnetic fields. All activities, from defining requirements final design measurements, were performed Laboratory Electromagnetic Compatibility at Faculty Applied Informatics Tomas Bata University Zlín. The hereby described approach allowed utilize standardized laboratory equipment is normally used for device test radiated electric field. made inside semi-anechoic room additionally damped by absorbers placed on its floor. When configuring relevant EMC standards EN 55016 61000-4-3 considered. Although uncertainty tolerances, standards, quite high measurements such rooms, obtained experiment matched theoretical expectations satisfactorily.
