General information about configuring Automatic connection

This setting is used to automatically connect:

• the client to the server without re-entering the server name, username and password when starting the app;
• the client to servers belonging to different domains (see Cross-System client);
• the client to the nodes of the failover system (see Configuring Failover VMS).

If you connect automatically, the servers

It is possible for the Client to automatically connect to Servers on different Axxon domains—Cross-System Client.

For this to take place, the following conditions must be true:

• Professional, Enterprise or Unified license has been activated on each Server to which the Client is connected (see Axxon One license types). For example, some of the Servers may have an Enterprise license activated, and some may have a Unified one;
• connection to all Servers made via with the same user name/password combination on each Axxon domain;

• Server names and IP addresses are unique.

Configuring the automatic connection

To configure the automatic connection, do the following:

1. Select the Options tab (1) → Automatic connection (

Configuration of automatic connection to Servers on different Axxon domains is performed as follows:

1. Go to Settings → Options → Automatic connection (1-2).

2. Configuring the protocol used by Clients to connect to the Server allows prioritizing reliability or speed of data transmission (3). The connection protocol is set individually for each Server in an Axxon domain. All Clients connected to the Server will receive video streams over the selected protocol.

   Descriptions and recommendations for selecting a protocol 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 but

   bandwidth-intensive. Recommended for Servers with small numbers

   has a busy connection. We recommend selecting it for servers with a small number of cameras
   UDP unicast	The UDP

   is typically faster but less reliable for data transmission. Unicast involves data transmission to a single recipient.

   protocol has a higher data transmission speed, but it is less reliable. The unicast scheme is used to transmit data to one recipient. You must select this protocol for a server with a large number of cameras that has several clients working with it
   UDP multicast	The multicast scheme is used to transmit data

   This protocol is best for Servers with many cameras connected to a single Client.

   UDP multicastMulticast refers to data transmission

   to a group of recipients. This protocol is

   designed

   best suited for

   Servers with many cameras connected to multiple Clients.

   Important! This protocol has to be supported by all network components, in particular, switches. 

   a server with a large number of cameras that has many clients working with it. Attention! To operate with this protocol, all network elements, including switches must support it

   The connection protocol determines whether you prioritize connection reliability or data transmission speed. You can select the connection protocol on the client side for each server individually. The client will receive video streams via the protocol specified in its connection settings.

3. For automatic authorization when connecting to servers, enter the username and password Type the user name and password needed for logging in to each Axxon domain (4). If you leave these fields emptyblank, manual authorization will be required when the Client starts.authorization is performed manually when you start the client.
   

   Note
   title Attention!
   The Cross-System client connects to all 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 waiting period Specify the Connection timeout parameter (5), which determines how long one must wait for a successful connection before considering the attempt to be unsuccessful. The default timeout value is 60 seconds, the maximum value is 300 seconds (5 minutes). When using If you use this setting, an automatic connection will attempt to connect occurs immediately. If the connection fails, the Server server will wait for a user-specified period of time the time period (timeout) specified by the user and retry repeat the connection attempt.
5. Specify the maximum number of automatic connection attempts after the specified timeout (6).
6. Indicate the Servers Specify the servers to which you want to connect to. For each Serverserver, perform do the following steps:

   1. Select a server from the list or enter the server IP address
   2. select the Server in the list (7);.
   3. indicate Specify the port for connecting to the Server server (8).

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

   After all Servers have been added to the list, select the main Axxon domain.
   When connecting, the Client

Configuration of automatic connection of the client to servers is complete. The next time you start Axxon One, the system connects to the selected servers.

Configuration of automatic connection of the client to servers belonging to different domains

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

When you connect, the client will use the parameters (maps, layouts, user

domain.

Configuration of automatic connection of the client to the nodes of the failover system

If you want to configure the automatic connection to a node of the failover system:

1. Set the Discover cluster checkbox (1).

2. Enter the IP address of any server of the cluster (2) and click the Image Added button.
3. From the drop-down list (3), select a node that you want to add to autoloading. 
4. Click the Add button.
5. Click the Apply Image Added button.

Configuration of automatic connection of the client to the node of the failover system is complete.

Configuration of automatic connection to the backup server

To automatically connect to the backup server if the main server in the N+1 cluster configuration is unavailable:

1. In the Automatic connection parameters group, enter the IP address and port of the main server, as well as the name of the node.
2. Click the Add Image Added button.
3. Set the checkboxes in the Main and Discover cluster columns.
4. In the Preferred servers parameters group, select a backup server from the list or enter its IP address and node name.
5. If necessary, change the default port for the backup server in the Port field.
6. Click the Add Image Added button.
7. Click the Apply Image Added button.

Configuration of automatic connection with the backup server is complete.
