Step 1, is to check the ONVIF Profile Directory. These are the current conformant products.
Step 2, is to check the ONVIF Archived Directory. These are legacy products. See: ONVIF Archives 1000+ Products
If the camera is not listed in either, it is by definition not conformant. If it is only listed in Archive, it is legacy conformant but risky to work with current ONVIF products.
What is the camera you are looking for?
If the camera is not listed in either,would you ask the manufacture to submit or resubmit?
first, from the formal point of view, there are no onvif conformant camers - there are conformant cameras+firmware.
second - in fact, manufacturers are not selling cameras with exactly the same firmware that pass onvif conformancy.
third - simular platforms have simular firmwares
and last but most important - onvif conformancy does not mean that device is really interoperable.
so i suggest to ask you searching engine for other user feedback about similar, if you are not trusting camera vendor documentation.
and, btw, if there are no one product of this manufacturer in conformancy list - this look like a cheat
Alex - great input. We are rolling out a new line of cameras and the only way to know for sure (best guess) is to test the cameras with popular vms platforms to see how they behave. Chip sets and firmware revs also dictate how a camera performs so this is pandora's box. ONVIF is "not" a real fully baked standard like 802.11 is in the networking arena. ONVIF is more of a guidline (correct me if i am wrong) so buyer beware in most cases.
