•Auto PAN

When a camera is set to this mode, it automatically turns between two preset positions horizontally. The availability of this function depends on the specifications of the con- nected camera.

•NAS (Network Attached Storage)

A network-attached storage (NAS) device is a server that is dedicated to nothing more than file sharing. NAS does not provide any of the activities that a server in a server- centric system typically provides, such as e-mail, authenti- cation or file management. NAS allows more hard disk stor- age space to be added to a network that already utilizes servers without shutting them down for maintenance and upgrades. With a NAS device, storage is not an integral part of the server. Instead, in this storage-centric design, the server still handles all of the processing of data but a NAS device delivers the data to the user. A NAS device does not need to be located within the server but can exist anywhere in a LAN and can be made up of multiple net- worked NAS devices.
