NTP SETUP
The unit’s internal time can be synchronized with an external time source using the Network Time Protocol (NTP) Date/Time configuration option.
•NTP: Sychronizes the DVR’s time. This feature must be set to ON before the NTP server is selected.
NOTE: If the NTP option is set to ON, the Date/Time option is unavailable.
•Server: Allows you to select a public or private NTP server. The default setting is PUBLIC SERVER. If you select public, the DVR computes
the average time from five public servers: time.nist.gov, time-a.nist.gov, timeb. nist.gov, ntp.nasa.gov, and clock.isc.org.
•Private Time Server: Allows you to enter the IP address of a private NTP server. Server must be set to PRIVATE SERVER before you can
enter an IP address.
•Sync. interval: Specifies how often the DVR synchronizes with the NTP server: daily (1 DAY), weekly (1 WEEK), monthly (1 MONTH), or
hourly (1 HOUR). The default is 1 DAY.
•NTP Test: Verifies network access to the NTP server.
