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.

following the set order (see Selecting Preferred Servers).

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

Configuring the automatic connection

To configure the automatic connection, do the following:

  1. Select the Options tab (1) → Automatic connection (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 From the drop-down list (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 , select the connection protocol to the server.
    Description of the protocol and recommendations for selection are given in the table.
    ProtocolDescription
    TCPThis 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 unicastUDP is typically faster but less reliable for data transmission. Unicast involves data transmission to a single recipient.

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

    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

    		UDP multicast

    Multicast 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 choice of either favoring connection reliability or data transmission speed depends on the clients' connection protocol to the server. You can select the connection protocol for each server of the domain. All clients connected to the server will receive video streams via this protocol.

  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 performed manually when the Client starts.you start the client.
    Note
    titleAttention!

    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 attempt will attempt to connect occur 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

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

When you use the Cross-System client, select the main domain after adding 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.

domain.

Configuring the 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, do the following:

  1. Set the Discover cluster checkbox (1).

If the Client is connected to several Servers, the Server settings are reproduced for each Server (see Server settings).
