IEEE 802.11 is a family of standards for wireless LANs. The 802.11 standard supports 1 or
2 Mbit/s transmission on the 2.4 GHz band. IEEE 802.11b supports data rates up to11 Mbit/s on
the 2.4 GHz band, while 802.11g allows up to 54 Mbit/s on the 5 GHz band.
Interlacing. Interlaced video is video captured at 50 pictures (known as fields) per second,
of which every 2 consecutive fields (at half height) are then combined into 1 frame. Interlacing was
developed many years ago for the analog TV world and is still used widely today. It provides good
results when viewing motion in standard TV pictures, although there is always some degree of
distortion in the image.
Internet Explorer (formerly Microsoft Internet Explorer, commonly abbreviated IE or MSIE)
is a series of graphical web browsers developed by Microsoft and included as part of the Microsoft
Windows line of operating systems, starting in 1995.
IP66 is a two digit number developed by the international electrical Commission, and is
used to provide Ingress Protection (IP) rating to a piece of electronic equipment or to an enclosure
for electronic equipment. The Ingress protection code indicates the level and amount of protection.
The first digit means no ingress of dust; complete protection against contact. The second digit
means water projected in powerful jets (12.5mm nozzle) against the enclosure from any direction
shall have no harmful effects.
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.
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.
