General information about configuring Automatic connection

This setting is used to automatically connect:

• the Client client to the Server server without having to re-enter the Server server name, username, and password when starting the app;
• the Client to Servers belonging client to servers that belong to different domains (see Cross-System client);
• the Client client to the nodes of the FailOver failover system (see see Configuring Failover VMS).

If you connect automatically, the Servers specified in the Automatic connection parameters group will be used first. If these Servers are unavailable, the system will try to connect to the Servers from the Preferred servers parameters group following the set order (see Selecting Preferred Servers).

Configuration of automatic connection

To configure automatic connection, do the following:

1. Go to the Settings tab → the Options tab → Special options → Automatic connection.
2. Specify the required settings listed in the table:
   

   Parameter	Value	Description

From the drop-down list (3), select the connection protocol.
Description of the protocol and recommendations for selection are given in the table.
ProtocolDescriptionTCPThis protocol is more reliable, but has a busy connection. We recommend selecting it for Servers with a small number of camerasUDP unicastUDP protocol has a higher data transmission speed, but it is less reliable. The unicast scheme is used to transmit data to a single recipient.
You must select this protocol for a Server with a large number of cameras and which has several Clients working with itUDP multicast

The multicast scheme is used to transmit data to a group of recipients. This protocol is best suited for a Server with a large number of cameras and which has many Clients working with it.
Attention! This protocol must be supported by all network elements, including switches

The connection protocol of the Clients to the Server determines the choice either in favor of connection reliability or in favor of data transmission speed. You must select the connection protocol for each Sever of the domain. All Clients connected to the Server will receive video streams via this protocol.For automatic authorization when connecting to Servers, enter the username and password (4). If you leave these fields blank, authorization will be performed manually when you start the Client.

    Normal connection		Provides connection to one server, while other servers serve as backups. If the main server is unavailable, connections to the backup servers are made sequentially. All servers must be in the same domain
    Cross-system connection		Provides simultaneous connections to several servers that belong to different domains. The main server connects first, followed by other servers (regardless of the availability of the main server). All servers must be in different domains
