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.
