In this case, the user used 3 active-servers for recording. The channel of each active-server is 32, 40 and 50. The user uses 2 redundant-servers for backing up their servers. How many licenses do they need to buy?
 

Formula:

• Camera license = Total channel of cameras minus free 32 channels.
• Substations failover license = The number of channels on the active server hosting the largest number of cameras multiplied by the number of redundant servers.
• The channel of cameras for each active server: 32, 40 and 50.
• The free channel for VIVOTEK camera: 32
• The number of redundant-servers: 2
• The user needs to buy 90 (32 + 40 + 50 - 32) camera license and 100 (50 x 2) substations failover licenses for this scenario.

Note:

• These licenses do not come with a hardware dongle.
• M x N structure supported.
• The CMS station will be the main station for the control and monitoring of all the active and redundant servers.
• The Substations failover license needs to be imported to the CMS server.
