according to access protocol or NTP server or adaptive. When selecting a protocol, the system
will correct time automatically according to the protocol; when selecting “NTP server”, you need
to fill NTP Server Address and NTP Port and configure Time Correction Interval; when selecting
“Adaptive”, select necessary adaptive protocols, set the Timing Priority sequence and enter
current Timing Protection Time (i.e. the save time during protocol switching).
Note: Access protocol means the protocol that the camera connects to a platform; NTP means
Network Time Protocol, a protocol for clock synchronization between computer systems.
NTP Clock Synchronization: Select “Enable” and configure “Server Address”, “NTP Port” and
“Time Correction Interval”. When it is enabled, the camera will correct time on a time basis of the
configured interval.
DST: DST (daylight saving time) is the practice of advancing clocks during summer months so
that evening daylight lasts longer, while sacrificing normal sunrise times and the time applied
during DST is called DST time. Select "Enable DST" and set “Start Time”, “End Time” and “Time

Serial Port
Serial port is used to control camera rotation, extended alarm input or device adjustment (subject to
devices). Usually serial port is identified as RS485 A/B. Match the ports by configuring RS485 port
parameters. Please configure the parameters such as “Baud Rate”, “Data Bits” and “Address Code”
according to the actual conditions.
