I have a huge campus of university with multiple building ( 20 to 30 small and big) we have cameras every where in the campus and also user traffic is on the same access switch , i m introducing a campus firewall so that the user traffic between the vlan will pass by firewall currently the CCTV server is not behiind the firewall and it is connected on the switch i would like to have a recommendation from experts for the below.

as recommendation CCTV server should be kept in a DC behind the palo alto firewall how i shld size the palo alto firewall considering CCTV traffic what question i need to ask for the cctv traffic , it is bit twist here becz we are not sizing the firewall on number of users, server, but there are cameras which will send a video traffic.
- one thing coming to my mind to size the firewall we can get the utlization of the switch trunk ports that is accumulating traffic in MBPS or GBPS for a user and camera's so i can consider 50% or 65% of camera traffic and rest user traffic.
The CCTV traffic will also pass campus firewall ( palo alto) so i need to size campus as well DC firewall.
As a best practice please advise The user traffic and cctv traffic should be isolated completely from the end user production traffic

Your hints will help me to take this task ahead.
