Improper setup can cause devices to display a wide range of symptoms including the wrong time on the overlay, connect failed messages and failure to record.


NTP Setup:

    Under  Use specific NTP servers, it should display the IP address of the SM5200, VideoXpert Accessory Server, or the VIP if running in dual core environment . There should NOT be a (#) in front of this line.
