DIN EN 62676-2-1:2014-11

The international electrotechnical standardization organization for alarm and electronic security systems together with many governmental organizations, test houses, industrial associations and equipment manufacturers have defined a common framework for video surveillance transmission in order to achieve interoperability between products. The purpose of the transmission system in a video surveillance system installation is to provide reliable transmission of video signals between the different types of Video Surveillance System (VSS) so far called CCTV equipment in security, safety and monitoring applications. This standard IEC 62676-2-1 is intended to introduce an IP network interface for devices in surveillance applications. In this part of the standard, a network protocol is specified for the full interoperability of video devices. IEC 62676-1-1 and IEC 62676-1-2 specify the minimum network performance standards and general compliance to existing, well-known international network standards. On top of these basic layers protocols are defined to accomplish the full interoperability of video devices. In surveillance applications IP video devices have to use standardized protocols to accomplish following functionality: video streaming, stream control, event handling, discovery, capability description, device management, PTZ control, auxiliaries and other functions. 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.
