Industry Standard ONVIF defines communication protocols such devices as IP-cameras, encoders, video recorders and video management systems. The Forum is a non-profit and is open to manufacturers, software developers, system integrators and end users. At the beginning of 2010 the number of participants of the forum ONVIF than 100 companies. The first provider of video management software with support for ONVIF was the company Milestone, while the nearest competitors, the company Genetec and iTV, promised his support in future versions of its products. At the same time, domestic suppliers, the company Synesis, Agrg Byterg and demonstrated the equipment with the support of ONVIF. Developers ONVIF chose the most ready technologies and adapt them for IP-Surveillance. In particular, the specification ONVIF built on modern web-services described by the language of WSDL, protocols RTP / RTSP, SOAP (XML), video compression standard H.264, MPEG-4, MJPEG. The standard defined the following aspects of the interaction of the transmitting devices (IP-camera, encoder, ip-Video Server) with the Accepted devices (video management systems, DVR / DVR):
An important advantage of standard ONVIF is good support for video analytics, Embedded IP-end devices such as cameras and encoders. Thus, the observation device can perform local detection, tracking and recognition of objects. These operational metadata for analysis along with videos and images will be transmitted via IP-based network protocols ONVIF to the control of and in the archive. Synesis company has developed a library management application devices based on standard ONVIF. Library and program is distributed free in the open code. Download the software can be on the site Source Forge, the project onvifdm. |
