ONVIF (Open Network Video Interface Forum)

ONVIF (the Open Network Video Interface Forum) is a global and open industry forum with the goal of facilitating the development and use of a global open standard for the interface of physical IP-based security products. ONVIF creates a standard for how IP products within video surveillance and other physical security areas can communicate with each other. ONVIF is an organization started in 2008 by Axis CommunicationsBosch Security Systems and Sony.[1]

It was officially incorporated as a non-profit, 501(c)6 Delaware corporation on November 25, 2008. ONVIF membership is open to manufacturers, software developers, consultants, system integrators, end users and other interest groups that wish to participate in the activities of ONVIF. The ONVIF specification aims to achieve interoperability between network video products regardless of manufacturer.

ONVIF concerns itself with standardization of communication between IP-based physical security products to achieve open interoperability between equipment from different manufacturers.

1. Members

  • In December 2009, the ONVIF member base had grown to 103 members. This comprised 12 full members, 13 contributing members and 78 user members. 
  • In December 2010, the forum had more than 240 members and more than 440 conformant products on the market. 
  • By January 2015, this had grown to more than 3,700 ONVIF conformant products and 500 members. 
  • By August 2016, this had grown to more than 6,900 conformant products on the market but shrunk to 461 members. 
  • In February 2020, ONVIF reached more than 14,000 conformant products.

2. Profiles, Add-ons and Specifications

ONVIF provides and promotes standardized interfaces for effective interoperability of IP-based physical security products. The work starts with defining the network interface specifications for ONVIF conformant products. Selected specifications can then be packaged into ONVIF profiles or add-ons that allow for product conformance claims by ONVIF members. A product must successfully pass an ONVIF test tool to claim conformance to a profile, and optionally, an add-on.

A. ONVIF Profile

An ONVIF profile has a fixed and comprehensive set of features that enable a functional product to be developed solely on the profile specification. A profile has mandatory as well as conditional features, which are features that should be implemented by an ONVIF conformant device or client if it supports that feature in any way, including any proprietary way. Specifications for profiles cannot be changed to ensure backward compatibility.

Profile D: For access control peripherals

  • Transfers input credential identifiers and requests for access
  • Performs actions such as locking/unlocking

Profile M: Metadata and events for analytics applications

  • Analytics configuration and information query for metadata
  • Configuration and streaming of metadata
  • Generic object classification support
  • Metadata definition for geolocation, vehicle, license plate, human face and body
  • Event interfaces for object counter, face and license plate recognition analytics
  • Sending events through metadata stream, ONVIF event service or over MQTT
  • Rule configuration for events

Profile T: For advanced video streaming

  • H.264 / H.265 video compression
  • Imaging settings
  • Motion alarm and tampering events
  • Metadata streaming
  • Bi-directional audio

B. ONVIF Add-on

An ONVIF add-on consists of at least one or more features that solve one use case. An add-on, by itself, is not comprehensive enough to qualify as a profile. Specifications for add-ons do not include optional requirements for devices/clients or conditional requirements for devices. To conform to an add-on, a product must also conform to an ONVIF profile.

C. Profile vs. Add-on

While the features included in profiles cannot be changed, add-ons are easily adaptable to evolving technology/specification requirements. An add-on, unlike a profile, supports version handling and can be updated quickly to adjust for new technology additions or updates.
