I am the Systems Administrator for my company and have been asked to purchase and install a new Camera system. I intend on creating a separate network, with a PoE switch, in order to optimize the system for the camera system. These 16 camera's will be indoors. Some cameras will be used for security within the building while others will be used to record items received and shipped by our company. I would like to be able to store footage for at least 3 months, which will probably require a SAN or a NAS. I have looked at the Buffalo Video Surveillance NAS Solution with Axis Communications Camera Support for Small Business as well as Netgear's ReadyNAS. While I know networking I realize there is a lot I don't know about Video surveillance systems, camera licensing, and good software and hardware that need to work together. I appreciate any and all help from the professionals at the CCTV forums.
