Ethernet:
The most common technology for communication within a wired network. It facilitates
data exchange between all devices (computers, printers, IP cameras, IP video phones, etc.) con-
nected in a local network (LAN).
Flash memory:
See MicroSD card.
fps
: Abbreviation for frames per second. See Frame rate.
Frame rate:
The frame rate specifies how many frames per second (fps) are generated and
sent by the camera. 16 fps and higher is perceived by the human eye as a fluid video sequence.
G.711:
G.711 refers to the process by which analog audio signals are encoded and decoded. This
codec (= enCOder-DECoder) is used in classic telephone systems and IP telephony.
H.264:
H.264 is the process by which the video image is encoded/compressed and decoded.
HDTV:
Abbreviation for High Definition TV.
HiRes:
Abbreviation for High Resolution. Refers to high-resolution images (above 1 megapixel).
Image compression
: Image compression reduces the file size of an image. This is particularly
important when transferring and saving files.
Image processing:
Digital image processing. The goal is to correct errors made during image
generation (caused by overexposure, underexposure, blurring, weak contrast, image noise, etc.)
in order to create a “better” image.
IP network:
Data network based on the Internet protocol (TCP/IP).
IP telephone:
See VoIP.
JPEG:
Abbreviation for Joint Photographic Experts Group, responsible for the development of the
JPEG standard method for image compression. JPEG is the most common lossy image format
for photos on the Internet. Loss in image quality is barely noticeable at compression rates lying
between 60% and 99%.
Latency:
Time interval elapsed between the time an image is captured by a camera and when
that same image is displayed on the monitor.
Layout:
Describes the layout of video sources on a screen in MxControlCenter. The layout deter-
mines the positions and resolutions of the images displayed on the monitor when displaying
images from network cameras. In addition to the actual video images, you can also incorporate
graphic elements such as the location of the cameras, etc.
LED:
Abbreviation for Light Emitting Diode. An electronic semiconductor component built into
MOBOTIX cameras and add-on modules that emits light when a current flows through the com-
ponent in the correct direction.
Megapixel:
Images that have more than 1 million pixels.
MicroSD card:
SD Memory Card (Secure Digital Memory Card). A digital storage medium based
on flash storage modules.
