The camera's NTP time synchronization can be set on the web interface or VCN platform. The parameters set later shall prevail.
If a camera sets the IP address of the NTP server, the VCN enables the NTP synchronization. After the camera is connected to VCN platform, its NTP IP address (inside the camera) will be replaced with the VCN IP address. Then the camera synchronizes time with the VCN. If a camera is connected to VCN platform and then the camera also sets the IP address of the NTP clock source on the web interface, the camera synchronizes time with the NTP clock source instead of the VCN.
