Which of the following is not an ONVIF standard?

The Open Network Video Interface Forum (ONVIF) provides a standardized framework for the interoperability of IP-based physical security products. These standards are organized into specific "Profiles" that define the features supported by devices and clients. Standard interfaces such as ONVIF are used to connect cameras to the IVS platform, facilitating a future-proof ecosystem where hardware from different vendors can communicate seamlessly.

Among the recognized standards, Profile S is the most common, used for basic video streaming and configuration. Profile T is a more modern standard designed for advanced video streaming, specifically supporting H.265 encoding and metadata reporting. Profile A is utilized for broader access control configurations, allowing for the integration of security management systems. Other profiles include Profile G for edge storage and Profile Q for quick installation. However, Profile B is not a recognized ONVIF standard profile. Adhering to these standardized formats ensures that recording streams can be accessed through external interfaces and that the system provides a channel for reporting metadata (structured data) for exchange with the platform, regardless of the underlying hardware differences.
