Incoming is hard, but outgoing can be done.

You create a class by means of matching on the IP adress of the server and 
camera (match access-group) and then you give that class a certain amount 
of bandwidth. So freehanding without testing if this actually works:

class-map match-all prio-data
match access-group name outgoing-prio-data

policy-map outgoing
  class prio-data
    bandwidth 10000

ip access-list extended outgoing-prio-data
  permit ip host 1.1.1.1 any

Then you apply under the interface:

int fa0/0
  service-policy output outgoing
