Per Björkdahl: chairman of the ONVIF Steering Committee
ONVIF, the global standardisation initiative for IP-based physical security products, has announced the final release of Profile T, a new specification with advanced video streaming capabilities and an expanded feature set for metadata streaming and analytics. Profile T also offers support for H.265 video compression, which “more efficiently” handles image streams from HD cameras.
With Profile T, ONVIF will employ a new media service that offers support for both H.265 and H.264 video codecs. The media service gives ONVIF the ability to more easily incorporate new video and audio codecs as needed as the industry continues to advance. By supporting H.265, Profile T supports more efficient compression rates, which translates into decreased storage requirements on hard drives and less bandwidth usage, in turn reducing the overall costs of system ownership.
“Profile T is an excellent example of how ONVIF has embraced technological advancements within its specifications to serve the changing requirements of this industry,” said Per Björkdahl, chairman of the ONVIF Steering Committee. “In addition to the H.265 support, Profile T standardises analytics, metadata streaming and other important features to satisfy both current and future market requirements for end users, system integrators and consultants.”
The new Profile T features bidirectional audio streaming, supporting audio input as well as output from the camera. Using standardised event types, Profile T ensures that video management systems and other software clients use one set of events to support all cameras, regardless of the manufacturer. This includes alerts such as tampering, digital input and relay output.
Profile T also enables a specific area of a given image to be selected for analysis, using the conditional motion region detector configuration through the analytics service. Profile T also covers the streaming of metadata, including analytics and events.
