I have been doing network monitoring for a long time, and the most heard is the agreement. Remember that it was a few years earlier, and everyone complained about one thing: the network is not as good as the simulation because the protocol is not compatible. So there is a standard protocol: ONVIF protocol.
So what is the ONVIF agreement, and what is its origin and fate? Today we are no exception, starting from the roots and slowly smoothing.
Speaking of ONVIF, it is committed to promoting the application of network video in the security market through a global open interface standard. This interface standard will ensure the interoperability of network video products produced by different manufacturers. In November 2008, the forum officially released the first version of the ONVIF specification-ONVIF Core Specification 1.0.
With the networked application of video surveillance, the division of labor in the industry chain will become more and more detailed. Some manufacturers specialize in cameras, some manufacturers specialize in DVS, and some manufacturers specialize in platforms, etc., and then integrate them through integrators and provide them to end customers. This kind of industrial cooperation model already urgently needs the industry to provide more and more standardized interface platforms (I vaguely remember that at that time, the high-definition network monitoring protocol was a mess. This protocol, that standard, this video recorder, and that camera all felt that they were standing on their own. At the air vent, it is called a cow. I didn’t expect that the pigs who stood at the air vent before became dead pigs. Why? Not open, there is no tolerance heart from beginning to end. At the same time, it has become the current security enterprise. Don’t If you don’t accept it, think about it carefully.)
For this reason, in May 2008, Axis, Bosch and Sony announced that they would jointly establish an international open network video product standard network interface development forum, named ONVIF (Open Network Video Interface Forum, Open Network Video Interface Forum). Video Interface Forum), and jointly develop open industry standards based on the principles of openness and openness.
The ONVIF standard will define general protocols for information exchange between network video devices, including device search, real-time video, audio, metadata, and control information. The various possibilities provided by network video products enable end users, integrators, consultants and manufacturers to easily benefit from them, and obtain cost-effective, more flexible solutions, opportunities for market expansion, and lower risks of.
The ONVIF specification describes the network video model, interface, data type, and data interaction mode. And reuse some existing standards, such as WS series standards. The goal of the ONVIF specification is to implement a network video framework protocol, so that network video products (including camera heads, video equipment, etc.) produced by different manufacturers are completely interoperable.
The interfaces defined in the device management and control part of the ONVIF specification are provided in the form of Web Services. The ONVIF specification covers the complete definition of XML and WSDL. Every terminal device supporting ONVIF specification must provide Web Service corresponding to its function. The data exchange between the server and the client adopts the SOAP protocol. Other parts of ONVIF, such as audio and video streams, are carried out through RTP/RTSP.
Normative advantage:
Synergy: Products provided by different manufacturers can communicate through a unified "language". Facilitate the integration of the system.
Flexibility: End users and integrated users do not need to be constrained by the inherent solutions of certain devices. Greatly reduce development costs.
Quality Assurance: The ever-expanding specifications will be oriented by the market, and while following the specifications, it also meets the needs of mainstream users.
The ONVIF organization is expanding day by day, and it occupies an absolute advantage in personnel compared with PSIA and HDCCTV in the same field. Member companies have many well-known equipment manufacturers and integrators at home and abroad. The life cycle of a set of norms and agreements is closely related to market share. The development of ONVIF specifications is guided by the market and enriched by users. Each member company has the right to strengthen and expand the ONVIF specification. The areas covered by the ONVIF specification will continue to increase. The relevant content of the current access control system will soon be included in the ONVIF specification. In today's rapid development of security and monitoring systems, the value brought by efficiency and quality leadership is self-evident.
