Nx Witness VMS, for example is able to support 99% of IP cameras (see the Nx Witness supported devices list) in the market today primarily because of ONVIF.HOUSTON-( BUSINESS WIRE)-Safety Vision, LLC pushes the Open Source, Open Architecture front in the industry by announcing that our 35 and 36 Series IP cameras have met all testing requirements for Profile S and Profile T conformance.
#Onvif s software
This has allowed software development companies like Network Optix to create open, extensible video management solutions with the ability to support hundreds of manufacturers and tens of thousands of devices.

As of May 2019, ONVIF standards have been implemented across 12,000 products. ONVIF has since been adopted by most manufacturers (both software and hardware) in the security industry today. As Hikvision and Dahua, at the time, were OEM manufacturers for many international surveillance brands this cemented ONVIF as THE industry standard. In the late 2000’s many large IP video device manufacturers in China like Hikvision and Dahua adopted ONVIF as a standard. ONVIF has collaborated with the International Electrotechnical Commission (IEC) and the European Committee for Electrotechnical Standardization (CENELEC) to ensure that ONVIF protocols become the international standard for all devices involved in security and surveillance. Profile T also covers ONVIF specifications for HTTPS streaming, PTZ configuration, motion region configuration, digital inputs and relay outputs, and bidirectional audio for conformant devices and clients that support such features. Mandatory features for devices also include on-screen display and metadata streaming, while mandatory features for clients also include PTZ control. An ONVIF Profile T device supports video streaming features such as the use of H.264 and H.265 encoding formats, imaging settings, and alarm events such as motion and tampering detection.Profile S also covers ONVIF specifications for PTZ control, audio-in, multicasting and relay outputs for conformant devices and clients that support such features. A Profile S client (e.g., a video management software) is one that can configure, request, and control video streaming over an IP network from a Profile S device. An ONVIF Profile S device (e.g., an IP network camera or video encoder) is one that can send video data over an IP network to a Profile S client.Profile Q also covers specifications for TLS (Transport Layer Security) configuration for conformant products that support this feature. A Profile Q conformant client is one that can discover, configure and control a Profile Q device over an IP network. An ONVIF Profile Q conformant device is one that can be discovered and configured by a Profile Q client.

Profile G also includes support for receiving audio and metadata stream if the client supports those features. A Profile G client (e.g., a video management software) is one that can configure, request, and control recording of video data over an IP network from a Profile G conformant device. An ONVIF Profile G device (e.g., an IP network camera or video encoder) is one that can record video data over an IP network or on the device itself.ONVIF Profiles G, Q, S, and T are for Video Devices
