Looking for alternatives for access control systems

Looking into alternatives for access control systems that could meet the following requirements:

1. OSDP protocol

2. Easy expansion (Single door add)

3. Simple user interface

4. Integrated video door panel for visitor door unlocking (two way voice, video one way) with a reader as well

5. POE power with enough oompf for typical strikes and maglocks built in to controller

6. Ability to connect peripheral equipment and run logic scripts for various inputs/outputs

7. Wireless locksets for doors.

8. Good warranty period

   Any suggestions?
