International. ONVIF, a leading global standardization initiative for IP-based physical security products, today announced the Release Candidate for Profile G, the specification designed to store, search, retrieve and play media on devices or customers that support onboard recording and storage capabilities. This new Profile is now available for review on the ONVIF website.
As with Profile S, which ONVIF introduced in 2012 as the standard interface for streaming video and audio between compatible devices and clients, Profile G now brings video playback to the Concept of Profile. Having the overall specifications of the interface, with specific functionalities easily identified by the Profiles, makes it easier for end users, integrators, consultants and manufacturers to take advantage of the opportunities offered by network video technology.
"The introduction of Profile G will complete the loop between live video and the other half of the equation, which is video storage," said Steven Dillingham, Chair of ONVIF's Profile G Working Group and Software Engineer for VidSys. "This further refines the level of interoperability between ONVIF's compatible products," he added.
Profile G will cover devices ranging from cameras and encoders to network video recorders (NVRs) and customer systems such as video management systems, building management systems, and physical security information management (PSIM) systems, among others. For example, Profile G can be implemented between a PSIM solution by integrating video playback from an NVR, including specific features such as the start and end of recording; video search using different filters such as time, event or metadata; video recovery and playback; and, on the receiver side, the creation of an IP media source.
ONVIF circulates the new profiles first as a 'Release Candidate' for six months, allowing members and stakeholders a final review of the implementation. When this process is complete, the Final Profile will be published and technology providers will be able to test their products for compliance with the final version of Profile G. This process is designed to allow members to more quickly introduce compatible products when the final G Profile is released in early 2014.
Although Profiles G and S are related, both are separate profiles and include different functionalities of a network video system. Some devices and most clients can deploy both profiles; for example a camera with on-board storage or a digital video recorder. In contrast, a camera can implement Profile S for video streaming, while an NVR would comprise Profile G functionalities.
There are currently more than 1,500 Products that conform to Profile S in the market of approximately 460 ONVIF member companies. You can learn more about ONVIF-compatible products on the ONVIF website, including compatible vendors and models: www.onvif.org
