Changes

All cameras installed after 2011 are a mix of brands, but are all IP-based and use Power over Ethernet. Brands seen around campus include 4XEM, AXIS, Arecont Vision, Pelco, and Sony. They are being placed in the private 172.22.0.0/16 subnet, which is a portion of the subnet used for wifi clients, clocks, and other things; cameras are typically unaccessible to normal users due to firewalling and/or routing policies.
