Modifying IP Address 4.3
To realize communication among video door phones, you need to modify IP address of the door
station. You can modify IP address on the door station or through the web interface. Modifying
IP address through the web interface will be demonstrated here. For IP address modification on
the door station, see "5.2 Setting IP Address."
Select Network Setting > Basic. Step 1
TCP/IP information Figure 4-3
Enter the network parameters that you planned, and then click Save. Step 2
Make sure that your PC IP address and the door station are in the same network
segment.
The VTO will restart.
Preferred DNS and alternate DNS are both 8.8.8.8 by default.
If PC IP address is in the planned IP segment, the interface will go to the login interface
automatically.
If PC IP address is not in the planned IP segment, the interface will not go to the login
interface. You need to make the PC IP address in the planned IP segment.
Selecting SIP Servers 4.4
The Session Initiation Protocol (SIP) is used for signaling and controlling multimedia
communication sessions in applications of voice and video calls. A SIP server is an application
that provides information or direction to a user agent.
When door stations (VTO) work as SIP server, select VTO from the Server Type
drop-down list. It applies to a scenario where there is only one building.
When the platform (Express/DSS) works as SIP server, select Express/DSS from the
Server Type drop-down list. It applies to a scenario where there are multiple buildings or
multiple units.
