IR-cut filter
Infrared cut-off filters are used in digital optical equipment, such as cameras, video
recorders and astronomical telescopes, to limit the amount of infrared radiation that
reaches their delicate CCD and CMOS imagers. These imagers are very sensitive to
infrared radiation, which can cause a color shift in the final image. Using an infrared cut-
off filter will reduce or prevent this color shift.
LAN/POE
Local Area Network/Power Over Ethernet
LED
Light emitting diode
Low latency
Low latency allows human-unnoticeable delays between an input being processed and
the corresponding output providing real-time characteristics.
lux
The lux (symbol: lx) is the SI (International System of Units) unit of illuminance and
luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per
square meter. In photometry, this is used as a measure of the intensity, as perceived by
the human eye, of light that hits or passes through a surface. It is the standardized model
of human visual brightness perception,
MAC address
Media Access Control address is a hardware identification number that uniquely
identifies each device on a network. The MAC address is manufactured into every
network card, such as an Ethernet card or Wi-Fi card, and therefore, cannot be changed.

MJPEG
In multimedia, Motion JPEG (M-JPEG or MJPEG) is a video format in which each video
frame or interlaced field of a digital video sequence is separately compressed as a JPEG
image. Originally developed for multimedia PC applications, M-JPEG is now used by
video-capture devices such as digital cameras, IP cameras, and webcams; and by non-
linear video editing systems.
MPEG4
Moving Picture Experts Group refers to a type of multimedia file, which is denoted by the
file extension ".mpg" or ".mpeg." These files are compressed movies that can contain both
audio and video. Though they are compressed, MPEG files maintain most of the original
quality of the uncompressed movie.
NAND
Logic gate NAND - AND followed by NOT: False only if A and B are both True
ND Shutter
In photography and optics, a neutral density filter or ND filter is a filter that reduces or
modifies intensity of all wavelengths or colors of light equally, giving no changes in hue
of color rendition. It can be a colorless (clear) or grey filter.
The purpose of a standard photographic neutral density filter is to allow the
photographer greater flexibility to change the aperture, exposure time and/or motion blur
of subject in different situations and atmospheric conditions. The use of an ND filter
allows the photographer to utilize a larger aperture that is at or below the diffraction
limit, that varies depending on the size of the sensory medium (film or digital) and for
many cameras, is between f/8 and f/11, with smaller sensory medium sizes needing larger
sized apertures, and larger ones able to use smaller apertures. ND filters can also be used
to reduce the depth of field of an image (by allowing the use of a larger aperture) where
otherwise not possible due to a maximum shutter speed limit.
