The Advanced Unit will synchronize the time on your DVR / NVR surveillance systems from within the surveillance platform, as required by many industries, as opposed to simple operating system based time adjustments. The Advanced Unit will grab the time from any NTP server that you specify, either from the LAN or from the WAN. This method will always ensure that you have accurate time stamps embedded into the OSD on your video assets. Once the Advanced Unit grabs the NTP time it will push it to all the configured DVR / NVR systems and adjust accordingly based on a configurable sync interval. The log file entries indicate the number of seconds, either forward or backward, that the time was adjusted.
