H
Host: A computer connected to a TCP/IP network. A host has its own IP address, but may -depending
on network configuration - furthermore have a name (host name) in order to make it easily identifiable.
HTTP: HyperText Transfer Protocol, a standard for exchanging files across the internet. HTTP is the
standard used for formatting and transmission of data on the world wide web.
I
I/O: Short for Input/Output.
IP: Internet Protocol; a protocol (standard) specifying the format and addressing scheme used for
sending data packets across networks. IP is often combined with another protocol, TCP (Transmission
Control Protocol). The combination, known as TCP/IP, allows data packets to be sent back and forth
between two points on a network for longer periods of time, and is used when connecting computers
and other devices on the internet.
IP Address: Internet Protocol address; the identifier for a computer or device on a network. Used by
the TCP/IP protocol for routing data traffic to the intended destination. An IP address consists of four
numbers, each between 0 and 256, separated by full stops (example: 192.168.212.2).
IPIX: A technology that allows creation and viewing of 360-degree panoramic images.
M
MAC Address: Media Access Control address, a 12-character hexadecimal number uniquely
identifying each device on a network.
MPEG: A group of compression standards and file formats for digital video developed by the Moving
Pictures Experts Group (MPEG). MPEG standards use so-called lossy compression as they store only
the changes between frames, removing often considerable amounts of redundant information:
Keyframes stored at specified intervals record the entire view of the camera, whereas the following
frames record only pixels that change. This helps greatly reduce the size of MPEG files.
P
PoS: Point of Sale.
PTZ: Pan/Zoom/Tilt; a highly movable and flexible type of camera.
R
RS-232: Shot for Recommended Standard 232; a standard interface for connecting serial devices.
S
SLC: Software License Code; a product registration code required for using the surveillance system
software. If you do not have system administration responsibilities, you do not have to deal with SLCs.
System administrators use SLCs when installing and registering the software.
Source: A data source through which transaction data is fed to the server and onward to the client
applications. Three different kinds of sources exist: Serial ports, TCP clients and Troy boxes. Sources,
in turn, are connected to the actual devices on which the transaction data is generated (cash registers,
ATMs, etc.).
