Infinova: The Importance of ONVIF for System Interoperability

There is simply no question about it. End users or integrators want the increased benefits of digital/IP video. But they run into big roadblocks on their journey from analog to digital. With digital surveillance, it is no longer simple to mix and match analog cameras and DVR brands. With digital, the basic components of a network video system are often nonstandard, including the network camera, NVR and VMS.

Integrators have been tearing their hair out because, seemingly, every digital camera vendor has created a separate camera interface. Oh, yes, 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 analog 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, 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's 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 has become so important.
If a product carries ONVIF certification, integration is standardized. 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 analog.

Why ONVIF?

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 majority of digital/IP manufacturers, software and hardware. This will be verified by a quick stroll through most of the events globally.
