Development of Installation Standards and Evaluation Indicators for CCTV Systems in National Security Facilities
In December 26, 2017, the Ministry of Science and ICT’s Cyber Infringement Response Division, the KCC’s Internet Ethics Team, and the National Police Agency’s Cyber Investigation Division announced the “Comprehensive IP Camera Measures” to prevent damage to users by strengthening IP camera security. The background was a countermeasure against the spread of public anxiety such as leakage of privacy and threatening national security as cases of illegal filming and distribution of videos by accessing IP cameras without permission at that time occurred. At that time, the measures consisted of three major strategies: institutionalization of products with security (manufacturing and import stage), rapid action and response to hacking threats in advance, and intelligent advancement of IP cameras (industrial development) and fostering various video and safety industries. This paper deals with the development of installation standards and evaluation indicators for CCTV systems installed in the relevant national security facility. When designing a CCTV system, the resolution and sensitivity of the camera, the angle of view of the lens, and the aperture should be selected in consideration of the length and width of the monitoring area. When it is necessary to determine an alarm based on the recorded image information, the resolution of the recording device should also be considered. If there is a restriction on the surveillance area of the camera due to topographic features, visitors, etc., additional cameras should be considered. Additional surveillance cameras should be considered to effectively monitor sections where fences are bent or sections with severe slopes. When designing a CCTV system, supplementary means that can be used for intrusion monitoring should be devised even if the entire or part of the system causes a failure. KISA’s performance test and certification procedures shall apply mutatis mutandis to intelligent CCTV image analysis test procedures and certification. Intelligent CCTV image analysis evaluates the performance of the equipment by comparing files of ground truth (GT) and system alarm (SA) for verification to calculate the evaluation score.
