ONVIF Profile M supports analytics configuration and information query for metadata, as well as filtering and streaming of metadata. It has interfaces for generic object classification, and specified metadata for geolocation, vehicle, license plate, human face and human body. If conformant products have native support for features such as media profile management, video streaming, adding images in metadata streams, event handling or rule configuration, then Profile M interfaces for those features must also be supported. And if conformant products support analytics for object counting (e.g. for people, vehicles), license plate recognition or facial recognition, or MQTT (Message Queuing Telemetry Transport) protocol used by IoT (Internet of Things) systems, then there should also be Profile M event handling interfaces for those functions.

A Profile M conformant product can be an edge device (such as an IP camera or video-based drone) or a service (such as a server- or cloud-based app) with analytics capabilities that can use Profile M interfaces to send metadata over an IP network to a client. A Profile M conformant client can be a video management software (VMS) program, a network video recorder (NVR), or a server- or cloud-based service that can make use of Profile M interfaces to configure, request and control the streaming of metadata over an IP network from a Profile M edge device or service. Profile M devices or clients with support for MQTT can also communicate with an IoT platform/application that can then communicate with IoT devices and applications.
