Mark Wilson touts the benefits of ONVIF.
There is simply no question about it. End-users want the increased benefits of digital/IP video. But they (whether end-user or integrator) run into big roadblocks on their journey from analogue to digital. With digital surveillance, it is no longer simple to mix and match analogue cameras and DVR brands. With digital, the basic components of a network video system are often non-standard, including the IP camera, NVR (network video recorder) and video management software (VMS).
Integrators have been tearing their hair out because, seemingly, every digital camera vendor has created a separate camera interface. There are standards in the networked surveillance industry – compression (H.264, MPEG-4) and streaming (RTSP), for example – but control and command interfaces are not standard yet. Thus, software and NVR manufacturers must create camera-specific interfaces to their solutions.
The good old days of analogue plug-and-play are of the past. Now, there is the challenge of interoperability among hardware to hardware and hardware to software implementations. As a result, many integrators are hesitant to promote digital surveillance solutions even though their customers want them.
To help, leading VMS vendors, including Milestone and Video Insight, have integrated hundreds of cameras and encoders into their platforms. Even so, integration between devices is lacking. For instance, the software supports some features on one camera but not on another. Again, it is the integrator that is on the line, having to determine if and how much interoperability there is between the selected software, cameras and recorders.
This is the crux of why ONVIF (Open Network Video Interface Forum) has become so important. If a product carries ONVIF certification, integration is standardised. ONVIF certified products work with other ONVIF certified products. If the integrator and end-user agree on using only ONVIF certified products, we are on our way back to the plug-and-play world of analogue.
ONVIF is real. It provides a standard to address interoperability problems in network video, including such important needs as defining interfaces for device configuration, event handling, PTZ control and similar issues. Most importantly, it has been embraced by the great majority of digital/IP manufacturers, software and hardware. This will be verified by a quick stroll through most of the leading events globally. Booth after booth will tout ONVIF certification.
