Prerequisites Due to the characteristics of ONVIF technology, you will need broadband Internet connection and at least one IP camera connected to your network.
As you could read above, ONVIF technology enables many more advanced functionalities - I guess the following explanation can be a good base for further ONVIF developments.
#Rtsp ip camera viewer code
I will show some useful code snippets that help you to implement an Onvif CCTV IP camera viewer that makes it possible to display the image and play the audio of your IP camera in a Windows Forms application. In this article I am going to introduce the basics of ONVIF developments. The ONVIF specification defines a common protocol for the exchange of information between network video devices including automatic device discovery, real-time video streaming, PTZ (Pan-Tilt-Zoom) control, advanced video analytics, etc. Open to all companies and organizations.Interoperability between IP-based physical security products regardless of manufacturer.Standardization of communication between IP-based physical security.ONVIF, that is committed to the adoption of IP in the security market, has the following three cornerstones: The ONVIF specification will ensure interoperability between products regardless of manufacturer. This is an open industry forum for the development of a global standard for the interface of IP-based physical security products. ONVIF is the acronym for Open Network Video Interface Forum. As my application is based on the ONVIF specification as well, let me write some lines about this technology in a nutshell. If you are also interested in this field of programming, it is important to know the basics of ONVIF technology. Due to its advantages, by now I'm also interested not just in building IP-based surveillance systems, but also in developing IP camera solutions. The greatest benefits of using IP-based systems over traditional analog CCTV (Closed-circuit television) systems are the followings: greater flexibility, better camera performance, easier system installation, better system integration and batter value.įigure 1: How an IP-based surveillance system workĪlhough IP CCTV has been available for around 10 years, this technology has started to spread just in the last few years.
IP-based cameras turn the analog camera image and audio into digital data then transmit this data over LAN or through the Internet (Figure #1). So do not hesitate to leave a constructive message related to this project! I am looking forward to your comments!īackground The future's surveillance systems (and today's most improved monitoring systems) are based on IP (that is Internet Protocol). Let me share my project in the hope that I can help anyone who wants to improve his/her video surveillance / security system – and I also hope you will contribute to my solution by providing any further useful development suggestion.
Unfortunately, the implementation of this protocol is a little different among camera manufacturers.I'm working on a huge ONVIF IP camera project using C#.NET and I learned something cool this week that I think would be useful for the C#Corner community. This protocol is only supported by the major camera manufacturers (AXIS, Bosch, Hikvision, etc.), so first you need to check whether your camera supports this protocol or not. As AES uses a symmetric key, both the video producer and video consumer need to know the key. SRTP uses the same ciphers as HTTPS, typically AES with 128 bit key length. IPCamLive supports SRTP protocol that is an extension of the RTP protocol to encrypt the video frames and audio data.

This protocol only encrypts the username and password (using digest authentication), but it uses the standard RTP protocol for transferring the media which protocol is not capable of securing the data. IP Cameras are using Real Time Streaming Protocol (RTSP) to transport the media (video and audio) from the camera to the server. But what if you want to secure the stream between camera and the server? Streaming from the server to the viewer is now secure thanks to the widespread HTTPS protocol.
