The IEC standard is intended to assist Video Surveillance Systems companies, manufacturers, system integrators, installers, consultants, owners, users, insurers and law enforcement in achieving a complete and accurate specification of the surveillance system. This International Standard does not specify the type of technology for a certain observation task. This IEC Standard specifies the minimum requirements and gives recommendations for VSS Systems installed for security applications. This standard specifies the minimum performance requirements and functional requirements to be agreed on between customer, law-enforcement (where applicable) and supplier in the operational requirement, but does not include requirements for design, planning, installation, testing, operation or maintenance. This standard excludes installation of remotely monitored detector activated VSS systems. This IEC standard also applies to VSS sharing means of detection, triggering, interconnection, control, communication and power supplies with other applications. The operation of a VSS shall not be adversely influenced by other applications. The responsible committee is Subcommittee DKE/UK 713.1 "Gefahrenmelde- und Überwachungsanlagen" ("Alarm and surveillance systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
