MIB (Management Information Base)
A collection of information for remote servicing using the SNMP (Simple Network Management Protocol).
MAC (Media Access Control)
A quasi-unique identifier attached to most network adapters (NICs). It is a number that acts like a name for a particular network adapter.
LAN (Local Area Network)
A LAN supplies networking capability to a group of computers in close proximity to each other such as in an office building, a school, or a home. A LAN is useful for sharing resources like files, printers, games or other applications. A LAN in turn often connects to other LANs, and to the Internet or other WAN (Wide Area Network).
IP address (Internet Protocol address)
IP address is a numerical label assigned to each device participating in a computer network that uses the internet protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing.
ISDN (Integrated Service Digital Network)
ISDN comprised of digital telephony and data-transport services offered by regional telephone carriers. ISDN involves the digitization of the telephone network, which permits voice, data, text, graphics, music, video, and other source material to be transmitted over existing telephone wires.
HTTP (Hypertext Transfer Protocol)
Protocol for transmitting data over a network.
GoP (Group of Pictures)
In MPEG video encoding, a group of pictures, or GoP, specifies the order in which intra-frames and inter-frames are arranged.
A system for setting the address of the camera remotely from the control system.
F-Number (aka Focal ration, f-ratio, f-stop, or relative aperture) in optics
The f-number of an optical system is the ration of the Len’s focal length to the diameter of the entrance pupil. It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography.
DNS (Domain Name System)
An internet service that translates domain names into IP addresses. Because domain names are alphabetic, they’re easier to remember.
DNR (Dynamic Noise Reduction)
Image noise is interference in the video signal that shows up as grainy specks. It can be caused by low lighting situation, a nearby power interference, heat, or device algorithms DNR is a technique of removing image noise from a video signal by applying a digital comb filter. It makes images clearer and reduces video file size.
DHCP (Dynamic Host Configuration Protocol)
Assigning dynamic IP addresses to devices on a network.
Term used to define the direction of data transmission between two parties. Half-duplex allows data transmission in both directions but not simultaneously. Full-duplex allows simultaneous data transmission.
DWD (Dust and Water proof Design)
Dust and Water proof Design
CIF (Common Intermediate Format)
Video format with 352 x 240/288 pixels.
