How many licenses will I require when using video server?

1. For Mainconsole 5.1 / Crystal 2.2 and above version,

--> One video server only charges 1-ch license. 

 

No matter how many analog channels on video server, 

One video server, which means "one IP address only needs 1-ch license".

 

2. For Titan / NVRSolo / NVRmini2

--> Every analog channel on videor server charges 1-ch license.

For example, there are 4 analoh channels on some video server,
then customer needs to purchase 4 channel licenses for this video server.
