12.8.1. DYNAMIC DNS SERVER (DDNS) CLIENT
The DDNS service enables easy access over the Internet to a recorder connected to a network without a fixed
public IP address using a friendly host name (Internet address) defined by the user. The service is available only to
registered users of popular DDNS services, such as DynDNS (www.dyndns.org), No-IP (www.no-ip.com), and DNS-
O-Matic (www.dnsomatic.com).
The use of the DDNS service requires a properly configured Ethernet interface (as described in chapter 12.8
COMMUNICATION SETTINGS)
and access parameters to the DNS server account. The configuration data of the
DDNS service client is stored in the
AR407.txt
file. The way to access this data is described above in chapter 12.8, in
Table 12.8, in item
DDNS client settings and status
. In order to eventually start the configured service, one must
additionally set the
Dynamic DNS server client
to the value of
Enabled
(Table 12.8). In order for the changes in
the DDNS configuration to be implemented immediately, switch off and on the DDNS service, disconnect the
Ethernet cable for a brief moment, or restart the device; otherwise, the update will be implemented after not more
than 10 minutes after the changes are made. Reliability of the service depends on the availability and load of the
DDNS service and delays in the update of the address may reach several dozen minutes.
The public IP address of the network in which the recorder is operating and the status of the DDNS service is
displayed in the device status window (which can be called up using the
[F]
+
[ESC]
buttons or the
[F]
button, see
chapter 10) and in the menu item
Dynamic DNS settings and status
(Table 12.8). The
DDNS:OK
status indicates
that the last update of the address in the DDNS service was implemented correctly; other codes may be of
intermittent nature (e.g. DDNS:17 which means initiation and DDNS:13 or 15 - temporary unavailability of the
service) or permanent nature, which indicates inadequate Internet connection, improper configuration of the
connection or service (codes 2 to 12, e.g. DDNS:5 means invalid username or password, DDNS:8 means invalid host
name, and DDNS:11 means unspecified error of the DDNS service).
Access to the Internet using a public IP address (host name) may be blocked by some Internet providers; in such
cases, contact your operator’s customer service office.
In order to use the services of other NO-IP (
ServiceIndex
=1 in
AR407.txt
) and DynDNS (
ServiceIndex
=0) service
providers, configure an account in the Internet service DNS-O-Matic (
ServiceIndex
=2) and in the recorder (the host
name can be set as
all.dnsomatic.com
or as the address of the host created in another service supported by DNS-
O-Matic).
NOTE:
Before the
AR407.txt
file is modified manually in a text editor, a backup copy must be made of the file (to use later
in the event of problems with improper configuration, when default settings were restored).
