Security Watch: ONVIF Publishes Profile G for Video Storage and Recording

New under-review standard to simplify integrated video installations


ONVIF has published the Release Candidate for Profile G, a specification which will encompass devices ranging from cameras and encoders to networked video recorders (NVR) and client systems such as video management systems, building management systems and physical security information management (PSIM) systems. The profile is focused on the storage, search, retrieve and playback media on devices or clients that support recording capabilities and on-board storage.

Profile G, for example, can be deployed between a PSIM solution integrating video playback from a NVR, including specific features such as starting and ending recording; searching video using various filters such as time, event or metadata; video retrieval and playback; and, on the receiver side, creating a source of IP media.

“The introduction of Profile G will complete the circuit between live video and the other half of the equation, which is video storage,” Steven Dillingham, Chairman of ONVIF’s Profile G Working Group and Software Engineer for Vidsys, said in a statement.

This newprofileis now available for review on the ONVIF website, www.onvif.org. ONVIF circulates new Profiles first as a “Release Candidate” for six months, enabling members and stakeholders to review. When that process is complete, the final Profile is published and technology providers will be able to test their products for conformance to the final version of Profile G. This process is intended to allow members to more quickly introduce conformant products when the final profile is released in early 2014.

Although Profile G and Profile S — which ONVIF introduced in 2012 as the standard interface to stream video and audio between conformant devices and clients — are related, the two are independent and encompass different functionalities of a network video system, although some devices and most clients may implement both.
