Caution! Be advised that there are several companies online selling through Newegg, Amazon, or Ali Express which sell cheap Chinese made cameras with knockoff chipsets and advertise such as ONVIF compliant when they are only partially or not at all compliant. Even more confusing is that ONVIF has created several profiles that are loosely followed by IP camera chipset manufacturers.At minimum an ONVIF camera should provide an [[RTSP]] stream utilizing a common compression algorithm. Motion detection, audio, remote viewing, camera settings, and PTZ control are features not guaranteed to work on these gray area ONVIF cameras. Do not expect to purchase an ONVIF camera and have it work with a security camera system unless it has been verified to do so by the company you are purchasing it from and vice versa.Some advanced functions of your IP cameras, such as motion detection, PTZ controls, etc. would not be available with the free version of the ONVIF software. Usually, the third-party ONVIF IP camera software companies require you to pay for a license, so that you can get more advanced features and configure more brands of IP cameras.Manufactures that offer IP cameras that are 100% compatible with ONVIF Profile S are a good choice. Camera models made by Honeywell, Panasonic, Dynacolor, Sony, Samsung, Pelco, Bosch, Axis and Arecont Vision can be ONVIF compliant but only some of their models, others may not. Keep in mind that ONVIF Profile S compliance may not include motion detection, settings changes, or PTZ control. Camera settings, video analytics, motion detection, and PTZ control are all called "conditional" features in ONVIF Profile S.[[Category:CCTV]] [[Category:Electronics]]
