As Hikvision and Dahua, at the time, were OEM manufacturers for many international surveillance brands this cemented ONVIF as THE industry standard. In the late 2000’s many large IP video device manufacturers in China like Hikvision and Dahua adopted ONVIF as a standard. ONVIF has collaborated with the International Electrotechnical Commission (IEC) and the European Committee for Electrotechnical Standardization (CENELEC) to ensure that ONVIF protocols become the international standard for all devices involved in security and surveillance.
