IP camera. The terms IP camera, network camera and Internet camera all refer to the
same thing - a camera and computer combined in one unit. It operates as stand-alone unit and
only requires a connection to the network.
Jack-45 is an eight-wire connector used to connect computers onto a local-area networks
(LAN), especially Ethernets. RJ-45 connectors look similar to the RJ-11 connectors used for
connecting telephone equipment, but they are a bit wider.
JPEG (Joint Photographic Experts Group).Together with the GIF file format, JPEG is an
image file type commonly used on the web. A JPEG image is a bitmap, and usually has the file
extension '.jpg' or ".jpeg." When creating a JPEG image, it is possible to configure the level of
compression to use. As the lowest compression (i.e. the highest quality) results in the largest file,
there is a trade-off between image quality and file size.
kbit/s (kilobits per second) is 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) is a group of computers and associated devices that typically
share common resources within a limited geographical area.
Lux is a standard unit of illumination measurement.
MAC address (Media Access Control 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.
Mbit/s (Megabits per second) is 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.
Motion JPEG is a simple compression/decompression technique for network 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.
MPEG-4 is a group of audio and video coding standards and related technology. The
primary uses for the MPEG-4 standard are web (streaming media) and CD distribution,
conversational (videophone), and broadcast television. Most of the features included in MPEG-4
are left to individual developers to decide whether to implement them or not. This means that there
are probably no complete implementations of the entire MPEG-4 set of standards. To deal with
this, the standard includes the concept of "profiles" and "levels", allowing a specific set of
capabilities to be defined in a manner appropriate for a subset of applications.
Multicast is a bandwidth-conserving technology that reduces bandwidth usage by
simultaneously delivering a single stream of information to multiple network recipients.
