Glossary
A
Analytics: Common term for the functionality you can achieve by analyzing a video stream in
order to recognize and find specific types of information. Analytics functionality can relate to license
plate recognition, face recognition, object recognition, etc.
Aperture: On a camera, aperture refers to the adjustable opening (a.k.a. iris) used for controlling
the amount of light coming through a lens. The aperture thus has a significant effect on the
exposure of images.
ATM: Abbreviation for Automatic Teller Machine, i.e. a cash dispenser.
C
CLK: Abbreviation for Connection License Key, a key required to use your analytics solution. The
key determines the number of cameras you are allowed to use with your solution, and thus how
many so-called connections you are able to establish.
Codec: A technology for compressing and decompressing audio and video data, for example in an
exported AVI file.
D
DirectX: A Windows extension providing advanced multimedia capabilities.
Dynamic Range: A camera's dynamic range determines, among other things, its sensitivity in
low- and high-light conditions, how it reacts to changing light conditions, and how sensitive it is to
infrared lighting.
E
Event: A predefined incident occurring on the surveillance system; used by the surveillance system
for triggering actions. Depending on surveillance system configuration, events may be caused by
input from external sensors, by detected motion, by data received from other applications, or
manually through user input. The occurrence of an event could, for example, be used for making a
camera record with a particular frame rate, for activating outputs, for sending e-mail alerts, or for
a combination thereof.
F
FPS: Frames Per Second, a measure indicating the amount of information contained in video. Each
frame represents a still image, but when frames are displayed in succession the illusion of motion
is created. The higher the FPS, the smoother the motion will appear. Note, however, that a high
FPS may also lead to a large file size when video is saved.
Frame Rate: A measure indicating the amount of information contained in motion video. Typically
measured in FPS (Frames Per second).
G
Gain: Gain is basically the way in which a camera takes a picture of a scene and distributes light
into it.
