Video Surveillance of Today: Compressed Domain Object Detection, ONVIF Web Services Based System Component Communication and Standardized Data Storage and Export using VSAF – a Walkthrough

The growing trend for surveillance systems performing multiple functions (video surveillance, access control, response co-ordination) driven by technology integration and interoperability is emerging because organizations increasingly viewing integrated security systems as inevitable and necessity. In this paper we focus on the interoperability aspect for video surveillance systems. An open standard has been developed by the Open Network Video Interface Forum (ONVIF) to facilitate the interoperability between networked surveillance video components. The ONVIF specification defines the network layer of IP security devices including automatic device discovery, video streaming and intelligent metadata. It is IPbased, makes use of web services and provides a formal conformance process. By employing the specification, interoperability is assured between products regardless of brand. End-users are enabled to compose the most suitable combination of products for their specific needs regardless of vendor and integration costs are reduced significantly. Conformance of products to the ONVIF specification is based on vendor self-declaration and applying test tools available for ONVIF members. With the latest advance in compression technology such as MPEG-4 AVC|H.264, a joint standard from ISO/IEC (ISO/IEC 14496-10:2009) and ITU-T (ITU-T Recommendation H.264 (03/10)), the surveillance system provides better video quality and larger video resolution, while not stressing the network bandwidth further. Moreover, a novel export format fostering interoperability not only between different installations but also close cooperation with legal authorities “MPEG-A Part 10 Video surveillance application format” has been published by the Moving Picture Experts Group (MPEG). It specifies the use of MPEG-4 AVC|H.264 along with content description metadata e.g. object identification and other particularly surveillance related information neatly arranged. The mission for this book chapter is to raise awareness for the specifications provided by standardization that ensure the interoperability of surveillance system as well as to

An extension of the AVC file format for Video Surveillance

This paper introduces and discusses a recent standardization project by the MPEG group that aims at providing an interoperable file format tailored to the needs of the surveillance industry. The new standard is called Video Surveillance Application Format and extends the H.264 — AVC file format specification. Based on a review of the application requirements, the rationale is provided for the technical design choices, and an example system implementation is described in detail. This provides interoperability at the data format and metadata levels. An example reference implementation instantiates and tests the design. The resultant is the specification of a file format suitable for large-scale camera network deployment.
