To provide operation of distributed system, you must configure the interaction between Servers, Remote Administrator’s workstations and Remote Clients. The interaction between Servers, Remote Administrator’s workstations and Remote Clients means database replication (for Servers and Remote Administrator’s workstations only) and event exchange. During configuration, you must specify for each Server, Remote Administrator’s workstation and Remote Client the lists of interacting and non-interacting Servers, Remote Administrator’s workstation and Remote Clients.

You can configure the interaction of surveillance system components from administration Server or, if there are dedicated subnets, from the node Server or Remote Administrator’s workstation.

To configure the interaction between the distributed system components, do the following:

  1. Go to the Architecture tab in the System settings dialog window (1).

  2. The Computer column displays the list of network names of Servers, Remote Administrator’s workstations and Remote Clients registered in the Hardware tab (2). In the Computer column, left-click the network name of the Server, Remote Administrator’s workstation or Remote Client to change its interaction settings. Text in the selected cell becomes grey.

    Note

    To search for a computer by name, use the Ctrl+F keyboard shortcut. The Search in tree window opens, enter the full computer name or its part and press the Enter button. Found computer is highlighted in grey in the list.

  3. The With computer column displays the list of those Servers, Remote Administrator’s workstations and Remote Clients, with which the selected Server, Remote Administrator’s workstation or Remote Client is able to interact (3).

  4. In the IP address column, specify the addresses of the computers you are connecting to (4). Features:

    1. By default, you must specify the IP address. If the DNS instead of IP allowed checkbox is set on the settings panel of the Security zone object in the Programming tab, you can specify DNS name instead of IP address.

    2. If computer addresses in the network are set automatically (DHCP is configured), then you can leave the IP address field blank.

    3. If computer name is correct, then the IP address can be filled in automatically. For this, enter the question mark "?" in the IP address field and press the Enter key on the keyboard.
    4. You cannot add computers with the same IP addresses, a warning message appears if you try to do so:

      If the entered IP address is already assigned to some computer in the system, the address is assigned to the added computer and the address of the computer that previously had the address is reset.

  5. If the specified IP address must be set for all connections with this computer in the distributed system, right-click in the IP address field and select Replace <Computer name> with <IP-address> connections in the menu. This is allowed if computers with one network interface are used in the distributed system and the specified IP address must be used to communicate with these computers.

    Attention!

    When you click the Apply button (see step 10), the changes are saved only for the current computer. In order for the IP address to be saved for all computers in the distributed system, click the Apply button pressing down the Ctrl key on the keyboard.

  6. If the checkbox in the Connection column and in the row corresponding to the Server, Remote Administrator’s workstation or Remote Client is set, then the data on system configuration of the selected Server, Remote Administrator’s workstation or Remote Client with any Server, Remote Administrator’s workstation or Remote Client is exchanged (5). To prohibit exchange of configuration data with the selected Server, Remote Administrator’s workstation or Remote Client, clear the checkbox in the Connection column.

    Note

    Server or Remote Administrator’s workstation always exchange configuration parameters with Remote Client, even if the Connection checkbox is clear for this Remote Client.

  7. If the checkbox in the Send events column and in the row corresponding to the Server or Remote Administrator’s workstation is set, then events are exchanged between selected Server or Remote Administrator’s workstation and any Server or Remote Administrator’s workstation (6). To prohibit event exchange with the selected Server, Remote Administrator’s workstation or Remote Client, clear the checkbox in the Send event column.

    Note

     Server or Remote Administrator’s workstation always exchange configuration parameters with Remote Client, even if the Send events checkbox is clear for this Remote Client.

    Note

     In order to set all checkboxes in the Connection or Send events columns, highlight a cell in the required column and press Ctrl+A. To clear all checkboxes, highlight a cell and press Shift+A.
  8. If modems are used for connecting the distributed system components, then fill in the Connection, User and Password fields in properties of the Computer object on the Hardware tab according to the Windows modem configuration used.
  9. Repeat steps 2-6 for each pair of Servers, Remote Administrator’s workstations and Remote Clients.
  10. Click the Apply button.

Interaction of the distributed video surveillance system components is now configured.

Let’s consider setup of a Server and Remote Client connection via videogate as an example. A diagram of interaction of relevant components is shown in the figure.

Note

Videogate is used in large distributed video surveillance systems for routing the video signals between Servers and Clients located in different subnetworks. For details, see General information on the videogate.

According to the diagram, shown in the figure above, interaction must be disabled between the Server and Remote Client. As a result, the Architecture tab displays the following configuration parameters:

  1. For the videogate (GATE), interaction must be set with the Server (SERVER1) and with the Remote Client (MN1).
  2. For Remote Client (MN1), interaction must be set with the videogate (GATE), and interaction with the Server (SERVER1) must be disabled.
  3. For the Server (SERVER1), interaction must be set with the videogate (GATE), and interaction with the Remote Client (MN1) must be disabled.

In Axxon PSIM, the Computer object corresponding to the Remote Client (MN1) isn't displayed on the Hardware tab of the System settings dialog window.

However, if you set the Send events checkbox (the Connection checkbox is clear), the Computer object corresponding to the Remote Client (MN1) is displayed on the Hardware tab on the Server (SERVER1), but it is marked with the icon and the object name is highlighted in grey color. It means that administration of the given object is forbidden.
