DVRs with Specific Timing Synchronization
External Time Synchronization:
The DVR Express® Core’s timestamps can be synchronized to an external timing source, such as GPS or IRIG-B.
This feature requires a time receiver device that has an output signal associated with the time logs provided to
the control PC (normally referred to as PPS - Pulse Per Second). This PPS signal is connected to one of the
general purpose TTL or LVDS inputs of the DVR Express® Core, and the data interface of the timing device is
connected to the control PC. The timing device could be an external device which communicates over RS-232,
or a PC card with a PCI or PCI Express interface.
This can also be accomplished using DVR Express® on a PC-Based DVR
