This setting is used to automatically connect:

• the Client client to the Server server without having to re-enter entering the Server server name, username and password when starting the app;
• the Client client to Servers servers belonging 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 servers specified in the Automatic connection parameters group will be are used first. If these Servers servers are unavailable, the system will try tries to connect to the Servers servers from the Preferred servers parameters group following the set order (see Selecting Preferred Servers).

Configuring

the automatic connection

To configure the automatic connection, do the following:

1. Select the Options tab (1) → Automatic connection (2).
   
2. From the drop-down list (3), select the server connection protocol.
   Description of the protocol and recommendations for selection are given in the table.
   

   Protocol	Description
   TCP	This protocol is more reliable

   Servers

   servers with a small number of cameras
   UDP unicast	The UDP protocol has a higher data transmission speed, but it is less reliable. The unicast scheme is used to transmit data to

   a single

   one recipient.

   the protocol specified in its connection settings.

3. For automatic authorization when connecting to Serversservers, enter the username and password (4). If you leave these fields blank, authorization will be is performed manually when you start the Clientclient.
   

   Note
   title Attention!
   The Cross-System Client client connects to all Servers servers using a single username-password pair that must be created in each domain (see Cross-System client).

4. In the Connection timeout field (5), specify the wait waiting period for a successful connection before considering the attempt unsuccessful. The default value is 60 seconds, the maximum value is 300 seconds (5 minutes). If you use this setting, an automatic connection attempt will occur occurs immediately. If the connection fails, the Server server will wait for the time period of time (timeout) specified by the user (timeout) and repeat the connection attempt.
5. Specify the maximum number of automatic connection attempts after the specified timeout (6).
6. Specify the Servers servers to which you want to connect. For each Serverserver, do the following:

      If you leave the Port field blank, the standard port 20109 will be is used for connection.

   3. Click the Add button (9).
      

      Info
      title Note
      If you use the Cross-System Clientclient, you can connect to only one Server server of each domain (see Cross-System client). That is why when you add a Server server to the list, all other Servers in that servers of this domain become unavailable for selection. To remove a Server server from the list, click the Image Removed the Image Added button.

Configuration of automatic connection of the Client client to Servers servers is complete. The next time you start start Axxon One, it will connect the system connects to the selected Serversservers.

Configuration of automatic connection of the

client to servers belonging to different domains

When you use the Cross-System Clientclient, select the main domain after adding you add all Servers servers to the list. To select the main domain, set the Main checkbox in checkbox in the corresponding column of the Server that is on the server that belongs to this domain.
