Dynamic DNS

In the Configure Dynamic DNS dialog, you set up the camera's DynDNS Client so that you can access the camera using a symbolic host name even though the camera's IP address keeps changing.


Connections via the Internet are typically established by Internet service providers. Normally, providers assign changing IP addresses which means that the camera's IP address is a different one each time a connection to the provider is established. Once the camera is connected to the Internet, you can only access it via the Internet if you know its current IP address.

The Domain Name Service (DNS) is an important Internet service. Using so-called name servers, this service provides decentralized databases which allow for allocating symbolic host names (e.g. to the respective IP addresses (e.g. However, the DNS service concept is based on statically assigned IP addresses. Originally, this concept was not designed to work with frequently changing IP addresses as used when dialing up to a provider.

In order to enable the DNS to also manage changing IP addresses, the Dynamic DNS Service (DynDNS) has been introduced. A mechanism has been added to the DNS service, which the camera can use to transmit its current IP address, so that the entry in the name server database is updated automatically.

Configuring the DynDNS Client

Prior to configuring the camera for DynDNS, you need to register a host name for your camera with a DynDNS service (e.g. For a list of DynDNS service websites, see the Service Type list box.

Description of Parameters

Parameter Description
Client This option enables or disables your camera's DynDNS client.
Service Type The DynDNS data transfer is not standardized. This has resulted in different data exchange formats for different DynDNS providers. Select the service type suitable for your DynDNS service.
Server Enter the symbolic name (e.g. or the IP address of your DynDNS provider's server.

If you are not sure which server to enter, leave this field empty. In this case, the camera automatically uses the standard server enclosed in parentheses in the Service Type field.

Host Name Enter the host name (e.g. that you have registered with a DynDNS service for your camera.
Login User Name Enter the user name that you have registered or that you have been assigned during the registration process with your DynDNS service.
Login Password Enter the password that is used for authentication at the DynDNS server.
Connection This field shows which connection the DynDNS client uses and if it is working properly. This is the connection defined for the standard route. For configuring the standard route, open the Routing dialog.

Testing the Configuration

Ethernet Connection

In this case, the camera's DynDNS client transfers the IP address just once when the camera has been rebooted.

If your network uses e.g. DSL to connect to the Internet, you need to make sure that the camera is rebooted periodically after the respective router has been assigned a new IP address. By default, a time task, which reboots the camera once a day, has been defined in the Time Tasks dialog.

For status information on this feature, open the System Messages dialog.

ISDN Dial-Out Connection

If you choose ISDN Dial-Out Connection as connection type, you need to reboot the camera so you can test the connection in the Test Current Network Configuration dialog. The log window will show whether or not you have logged on to the DynDNS server successfully.

Klicken Sie auf Setzen, um die Einstellungen zu aktivieren und bis zum nächsten Neustart der Kamera zu sichern.

Beenden Sie den Dialog durch Klick auf Schließen. Hierbei wird geprüft, ob Änderungen der Gesamtkonfiguration vorliegen. Ist dies der Fall, werden Sie gefragt, ob die Gesamtkonfiguration dauerhaft gesichert werden soll.

 Zum Aktivieren der neuen Einstellungen speichern Sie die Konfiguration und führen einen Neustart der Kamera durch!
