Profile T release

New from ONVIF, the US-based standardisation initiative for IP-based physical security products, is the final release of Profile T. It’s a new specification with advanced video streaming and more features for metadata streaming and analytics.

With Profile T, ONVIF will employ a new media service that offers support for H.265 and H.264 video codecs. That lets ONVIF incorporate new video and audio codecs as needed. By supporting H.265, Profile T supports more efficient compression rates, which translates into decreased storage requirements on hard drives and less bandwidth usage – reducing the overall costs of system ownership, ONVIF says.

Per Björkdahl, chairman of the ONVIF Steering Committee said: “Profile T is an excellent example of how ONVIF has embraced technological advancements within its specifications to serve the changing requirements of this industry. In addition to the H.265 support, Profile T standardizes analytics, metadata streaming and other important features to satisfy current and future market requirements for end users, systems 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 means that video management systems and other software clients use one set of events to support all cameras, regardless of manufacturer. This includes alerts such as tampering, digital input and relay output. Profile T also enables a specific area of an 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.


Founded in 2008, it’s a forum for interoperability for IP-based physical security products. There are more than 10,000 profile conformant products. ONVIF offers Profile S for streaming video; Profile G for edge recording and storage; Profile C for physical access control; Profile Q for improved out-of-the-box functionality, Profile A for broader access control configuration and now Profile T for advanced streaming.
