|| **Question** 
When applying the ANPR licenses should i use the Cathexis CLPR-2000 software license and need the CLPR-1001 license for each camera?Are there any limitations when using Cathexis LPR with existing Cathexis servers.

| **Answer**
Yes , you will require a CLPR -1001 license for each camera. If you have 2 detection zones configured on the camera you will need 2 of these licences. No restrictions on the servers - ideally at least an i5 or i7"
