Alarm systems - CCTV surveillance systems for use in security applications - Part 5-2: IP Video Transmission Protocols
 N EN 50132-5-2

Annotation

This European Standard introduces 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. EN 50132-5-1 specifies 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.

This European Standard consists of 3 sections. The first section defines protocol requirements to be fulfilled by any high-level IP video device interface.

The following two sections – Annex I and Annex II- define two alterative protocols, one is based on HTTP and REST services and the second is based on Web Services.

In the future a third high-level IP protocol may be defined in Annex III, which grants compatibility to the requirements of this standard series. Today no third IP video protocol implementation is available.

Some areas of this transmission standard are covered by more than one approach, e.g. UPnP, ZeroConf and WS-Discovery.

The network protocols recommended and defined by this Video Transmission Standard are selected with a sense for future relevance and further extensions.
