ActiveX
ActiveX is a framework for defining reusable software components (known as controls) that perform a particular function or a set of functions in a way that is independent of the programming language used to implement them.
AC
In alternating current (AC, also ac) the movement (or flow) of electric charge periodically reverses direction. An electric charge would for instance move forward, then backward, then forward, then backward, over and over again. Refers from Wikipedia.
AF(Auto Focus)
An ability by which the camera lens automatically adjusts its focus on the captured subject.
AGC
Automatic Gain Control, an electronic circuit which amplifies the video signal when the signal strength falls below a given value due to the lack the light on the image device.
AVI
An Audio Video Interleave, a Microsoft multimedia file format. An AVI file contains both audio and video data in a standard container that allows simultaneous playback.
AWB
Automatic White Balance, is used in digital camera to automatically compensate the type of light (daylight, fluorescent, incandescent, etc.,) or lighting conditions in the scene. To make it normal for the human eye.
Analog Camera
An A conventional surveillance camera without USB or Ethernet connectivity. Analog surveillance cameras typically output analog composite video signals over coaxial cable.
Analog Video Output
Automatic Analog video output enables installers to monitor the camera output on a conventional video monitor. It's ideal for pointing the camera, setting the focal length and adjusting for lighting conditions.
Auto IRIS
An A kind of iris, is used to adjust the amount of enter light, electrically controlled by the camera.
Bit Rate
AutomaticIs the number of bits that are conveyed or processed per unit of time, often in conjunction with Kbit/s or Mbit/s.
Bi-Directional Audio (G.711/726)
An This feature conveys real-time audio between an IP camera and the central office. This enables an attendant in the central office to have a conversation with a person at the camera location. The system requires microphones in both locations and an amplified speaker at the camera position. The G.711 and G.726 compression standards preserve network bandwidth, enabling telephone-quality audio at very modest bit rates.
Bitmap
A storage method of digital image. A bitmap is created whenever an image is scanned and defines a display space and the color for each pixel or bit. It can then be saved as a JPEG, GIF or other type of file.
BrickOne Solution
An BrickOne Solution: A total-solution service proposed by Brickcom. In addition to the traditional Ethernet cabling that brings together all the IP surveillance components (camera, NVR, CMS, etc), Brickcom provides a full series of network connectivity products (ex. Wi-Fi, 3G, WiMAX, PLC) as well as consulting service that help the client design the system easily, flexibly and beyond the Ethernet cabling's constraints. The client benefits from the one-stop shopping and fully-tailored customization service brought by BrickOne solution.
CMOS
Automatic Complementary Metal-Oxide Semiconductor, one type of image sensor found in digital cameras.
Codec
An Common Gateway Interface, A set of rules that describe how a web server communicates with other (CGI) programs.
CIF
Automatic Common Intermediate Format, a video format used in analog video. The resolutions are 352x288 pixels for PAL and 352x240 pixels for NTSC.
