If you have set a public DDNS (dyndns.com, no-
ip.com or changeip.com), it may take 30 to 60
seconds until the IP address of the host name
(URL) can be updated in the DNS.
When using the network by connecting an IP
router to the main system, the network port
has to be designated from the setup menu of
the IP router. The main system uses 1494ports
(554-2048) for the TCP communication. When
using it by assigning IP addresses dynamically
to the main system while using the DHCP
function supported by the IP router, the port
number for the IP address dynamically assigned
from the setup menu of the IP router needs to
be designated. When using an IP router, it is
recommended to designate the IP address and
port number to be assigned to the main system
from the setup menu of the IP router, to set a
fixed IP address for the connection mode of
the main system, and to enter the IP address
designated to the IP router. Please refer to the
IP router manual or contact the manufacturer for
the IP router setup method.
NTP Setup
Primary Address & Secondary Address
Sets the NTP server address.
Connection Status
You can check the connection status with the NTP
server by pressing “Test” after entering the NTP server
address.
If the message “Success” is displayed, the NTP
server is in the state possible to communicate; if the
message “Failed” is displayed, it is not possible to
communicate.
NTP Enable
When using the NTP function, please check the “NTP
Enable
” box.
When the DVR system time prior to operating
the NTP setup function is set faster than the
NTP standard time (in other words, the DVR
system time is set to a past time through the
NTP setup), the recording function will not
operate for the protection of previously recorded
data. The recording function will operate
normally from the point that the newly set time
exceeds the original time value.
When the NTP function is in use, a time change
can not be made from the time setup menu and
it only allows setting the standard time zone.
The synchronization between NTP server and
DVR system will be performed every hour.
