Not necessarily. All ONVIF profiles have a defined set of functionalities that must be supported by a device and a client. Functionalities that are brand-specific to a product are not supported by ONVIF profiles. In the case above, the brand-specific functionalities will work only if the client also incorporates support for the product’s brand-specific functionalities. If this is the case, then the system can use both the ONVIF interface for functionalities defined by the ONVIF profile and the brand-name product’s interface for the brand-specific functionalities.
