| Method for setting the parameter value | Parameter description | Representation | Default value | Value range |
1 | Identification number* | Automatically | Displays the identification number of the Failover service object | Numbers, letters, periods, hyphen, dash, and underscore | NA | Depends on the number of the Failover service object in the video surveillance system with distributed architecture |
2 | Name* | Enter the value in the field | Sets the name of the Failover service object in the video surveillance system with distributed architecture | Latin, Cyrillic, numbers, and service characters | Failover service | A line containing a sequence of any characters (letters, digits, service characters except > and < characters), case-insensitive.
