Host Configuration Protocol (DHCP) server available to perform that function. Also known as
AutoIP.
Bridge See Wireless Bridge.
Camera, IP See S2500e, S2600e Series, or S2700e Series.
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 Intermediate Format) A video format that easily supports both NTSC and PAL

connects to the RS-232 interface. Nextiva edge devices 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)

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.
DVR (Digital Video Recorder) A device (usually a computer) that acts like a VCR in that it
has the ability to record and play back video images. The DVR takes the feed from a camera

Edge Device A Nextiva device transmitting or receiving video signals through an IP
network. The devices can be wireless or wired; some transmitters are IP cameras.
Encoder See Transmitter.
Ethernet A local area network (LAN) architecture using a bus or star topology and
supporting data transfer rates of 10, 100, and 1000 Mbps. It is one of the most widely
