The ONVIF commands do not work and authentication fails.
When using ONVIF commands or authentication on Sarix cameras version 1.8.2 and above.
ONVIF requires authentication to work properly and part of the authentication process is time. The camera and head-end need to be at the correct time in order for the authentication and commands to work properly.
Use a true NTP server to keep the time correct and in sync for both the camera and the head end equipment.
