the largest file, there is a trade-off between image quality and file size.
kbit/s (kilobits per second) -
A measure of the bit rate, i.e. the rate at which bits are passing a given point. See also
Bit rate
.
LAN (Local Area Network) -
A LAN is a group of computers and associated devices that typically share common resources within a
limited geographical area.
Linux -
Linux is an open source operating system within the Unix family. Because of its robustness and
availability, Linux has won popularity in the open source community and among commercial application
developers.
MAC address (Media Access Control address) -
A MAC address is a unique identifier associated with a piece of networking equipment, or more
specifically, its interface with the network. For example, the network card in a computer has its own MAC
address.
Manual iris -
This is the opposite to an auto iris, i.e. the camera iris must be adjusted manually to regulate the amount
of light allowed to reach the image sensor.
Mbit/s (Megabits per second) -
A measure of the bit rate, i.e. the rate at which bits are passing a given point. Commonly used to give the
"speed" of a network. A LAN might run at 10 or 100 Mbit/s. See also
Bit rate
.
Monitor -
A monitor is very similar to a standard television set, but lacks the electronics to pick up regular
television signals.
Motion JPEG -
Motion JPEG is a simple compression/decompression technique for networked video. Latency is low
and image quality is guaranteed, regardless of movement or complexity of the image. Image quality is
controlled by adjusting the compression level, which in turn provides control over the file size, and
thereby the bit rate.
High-quality individual images from the Motion JPEG stream are easily extracted. See also
JPEG

MPEG (Moving Picture Experts Group) -
The Moving Picture Experts Group develops standards for digital video and audio compression. It
operates under the auspices of the International Organization for Standardization (ISO). The MPEG
standards are an evolving series, each designed for a different purpose.
