IDPS - Intrusion detection and prevention systems identify possible incidents, logging information,
reporting attempts, identifying problems with security policies, documenting existing threats, and deterring
individuals from violating security policies. [Reference: PIDS]
IEEE – Institute of Electrical and Electronics Engineers; a US standards body.
IES – Illumination Engineering Society
IETF – The Internet Engineering Task Force, a public forum that develops standards and resolves
operational issues for the Internet. IETF is purely voluntary.
INCITS – International Committee for Information Technology Standards
Infrared cards contain a series of bar codes, similar to standard bar code cards, that are only visible when
exposed to infrared light. When the card is exposed to the special light, the bars cast a shadow behind the
card which is then read by the reader. They are relatively low in cost, very reliable, not easily duplicated,
and offer a good level of security but can be difficult to laminate for use as an ID card.
Interlaced Video – A technique used for television video formats, such as NTSC and PAL, in which each
full frame of video actually consists of alternating lines taken from two separate fields captured at slightly
different times. The two fields are then interlaced or interleaved into the alternating odd and even lines of
the full video frame. When displayed on television equipment, the alternating fields are displayed in
sequence, depending on the field dominance of the source material.
Inherence – the relation of an attribute, element, etc., to its subject.
IRE – Institute of Radio Engineers (now known as the IEEE)
Iris Recognition – A biometric process that uses an image of the physical structure of a person’s iris for
recognition purposes. The iris muscle is the colored portion of the eye surrounding the pupil.
ISM – Instrument, Scientific, and Medical band, used for unlicensed transmissions authorized under the
TCC Part 15 rules.
ISO – International Organization for Standardization, a primary standards development and issuance
organization based in Geneva, Switzerland.
ISSA: Integrated Security System for Airports
JPEG/MPEG: Both the Joint Photographic Experts Group and the Motion Picture Experts Group represent
standards for the storage and retrieval of compressed video and still pictures.
Key: A sequence of characters used to encode and decode a file and may be alphanumeric or condensed
(hexadecimal). In the network access field, "key" often refers to the "token," or authentication device
utilized to send and receive challenges and responses during the user authentication process.
Keypad – A numeric pad on which a user may enter a numeric code allowing the system to read and
respond – perhaps allow a door to be opened as a result. May or may not be used in tandem with other
media / devices (cards, keys, etc.). LAN – Local Area Network interconnects computers in a limited area
with higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication
lines than wide-area networks.
LLL – Low-Light Level
LMR – Land-Mobile Radio (public or private); a wireless communications system intended for use by
terrestrial users in vehicles (mobiles) or on foot (portables). Used by emergency first responder
organizations, public works organizations, or companies with large vehicle fleets or field staff; sometimes
