Data gateway is needed when live video is transmitted from Agent of Control to Additional workplace in another subnet and Monitoring software components are not united in the distributed video surveillance system, as so as in this case Video gate object cannot be used.

The Data gateway objects are created on the computers with Server of Control installed. The number of the Data gateway objects must be equal to the number of Agent of Control to receive live video from.

In this section, the description of Data gateway configuration is given. By default, this module is not enabled for live video transmitting to Additional workplaces. In order to enable Data gateway, set the View live video through the gate in the Monitoring interface object settings panel – see  Configuring the Monitoring interface object.

Data gateway object configuration is performed as follows:

1. Create the Data gateway object based on the Computer object on the Hardware tab of the System settings dialog box (1).
   
2. In the Local port field enter the number of the port to which live video from Agent of Control will be received (2).
3. In the Remote IP-address field enter IP-address of the Additional workplace (3).
4. In the Remote port field enter the port of the Additional workplace (4).
5. Click Apply (5).

Data gateway object configuration is completed.
