To provide the operation of the distributed system, you must configure the interaction between servers, remote administrator workstations, and remote clients. The interaction between servers, remote administrator workstations, and remote clients means database replication (for servers and remote administrator workstations only) and event exchange. During configuration, you must specify for each server, remote administrator workstation, and remote client the lists of interacting and non-interacting servers, remote administrator workstations, and remote clients.

You can configure the interaction of surveillance system components from the administration server or, if there are dedicated subnetworks, from the server or remote administrator workstation node.

Let’s consider the setup of the server and remote client connection via videogate as an example. A diagram of the interaction of relevant components is shown in the figure.

Videogate is used in large distributed video surveillance systems for routing video signals between servers and clients located in different subnetworks.

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 the 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.
