Access Point A device acting as a communication switch
for connecting wireless units to a wired LAN. Access points
are mainly used with wireless transmitter units to transfer
wireless content onto the wired IP network.
APIPA (Automatic Private IP Addressing) A feature of
Windows-based operating systems that enables a device to
automatically assign itself an IP address when there is no
dynamic host configuration protocol (DHCP) server available
to perform that function. APIPA serves as a DHCP server
failover mechanism and makes it easier to configure and
support small local area networks (LANs). Also known as
AutoIP.
Bridge A unit linking a wireless network to a wired
Ethernet network. The newest SmartSight bridge is the
S3100.
CCTV (Closed Circuit Television) A television system in
which signals are not publicly distributed; cameras are
connected to television monitors in a limited area such as a
store, an office building, or on a college campus. CCTV is
commonly used in surveillance systems.
CIF (Common Image Format) A video format that easily
supports both NTSC and PAL signals. Many CIF flavors are
available, namely CIF, QCIF, 2CIF, and 4CIF. Each flavor
corresponds to a specific number of lines and columns per
video frame.
CLI (Command Line Interface) A textual user interface in
which the user responds to a prompt by typing a command.
All SmartSight units have a built-in CLI allowing their
configuration.
Codec (Coder/Decoder) A device that encodes or decodes a
signal.
DCE (Data Communication Equipment) In an RS-232
communication channel, a device that connects to the
RS-232 interface. SmartSight units and modems are DCE.
Decoder See Receiver.
DHCP (Dynamic Host Configuration Protocol) A
communication protocol that lets network administrators
manage centrally and automate the assignment of Internet
Protocol (IP) addresses in a network.
DTE (Data Terminal Equipment) In an RS-232
communication channel, the device to which the RS-232
interface connects. Computers, switches, multiplexers,
cameras, and keyboards are DTE.
