Serial Port - Kedacom IPC4X2 Series User Manual

HD Mini Dome Camera

Set device time zone and device time: Click "Manual Setting", select time zone and set time on the popup
interface. You can select "Synchronize time with PC" and click "Save" to validate setting.

Auto Time Correction: Select "Auto Timing" and the system will correct time automatically according to the
selected access protocol (including NTP server, VSIP, ONVIF, GB28181) or adaptive. Configure the timing
protection time.
 Adaptive: 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).

Access protocol: the protocol of the device accessing to t platform or a server. When selecting a
protocol, the system will correct time automatically according to the protocol.

 NTP Clock Synchronization: Select "Enable" and configure "Server Address", "NTP Port" (certain to be
"123") and "Time Correction Interval". When it is enabled, the camera will correct time on a time basis of
the configured interval.
Note: NTP stands for Network Time Protocol, and it is an Internet protocol used to synchronize the clocks
of computers to time reference. It could synchronize PC to its server or the clock source such as
quartz clock and GPS; it could provide highly precise time correction (compared with the standard,
time difference is less than 1 ms on LAN and decades ms on WAN), and could prevent vicious
protocol attack by means of encryption confirmation.

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 Deviation".

8.4 Serial Port

Go to Settings > System > Serial Port, and configure the 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. Pair 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. Click "Save" to validate settings.
Attention: Serial Port 2 is internal parameter of the PTZ and is forbitten to be edited.
Picture 8-10 Manual setting of time
In the box of "Timing Priority", the priority level decreases from top to bottom.
Select a protocol and click "Up" to improve its priority and "Down" to decrease its priority; click
"Default" to apply the default priority levels.
If selecting "NTP Server", configure the parameters thereof.
