NTP
In the NTP section of the Configuration page user can configure NTP peers that are to be used by Video
Grabber. It is possible to setup up to two NTP servers. Video Grabber will automatically pick correct
network interface to communicate with them so there is no need to assign NTP specifically to either
LAN1 or LAN2.
