ONVIF stand for Open Network Video Interface Forum.
The surveillance industry has created an open standard protocol called ONVIF that allows cameras to communicate with each other and with network recording devices. ONVIF has different versions of compatibility that dictate which features can be integrated into the system.
Benefit of ONVIF protocol is, it allows the IP camera and software manufacturers to use the same protocol, so it’s unnecessary to rewrite code every time a new IP device comes to the market or a new IP surveillance software is launched.
ONVIF Profile S has changed over time and has evolved as the industry as has evolved. This means that if you want to use an advanced feature (such as motion recording or video analytics) with one of our NVRs and one of someone else’s cameras, you will need both products to be compliant with at least the version that introduced that feature.
