Shielding protection comparison for security cameras lenses

Abstract

The paper focuses on shielding effectiveness calculations of grid protections for camera objectives and their comparison. Security cameras represent the fundamental elements of physical guarding and help to improve a feeling of safety. Unfortunately, cameras are electronic device susceptible to electromagnetic field effects; therefore, the demand for protection is rising in recent years. The most cost-effectiveness solution is shielding enclosure which may be problematic to realise in this case just because of the lens. As an ideal solution to this problem seems to be shielding grid including different shapes of networks. The paper should provide information which type of shielding grid is the most effective. © 2018 IEEE.
