DVR: Abbreviation for Digital Video Recorder.
Events: An event refers to a situation when something happens or changes. In terms of video
surveillance, this means a change in the status of an area that is being monitored. This may be
movement of a person, a change in brightness, a drop in ambient temperature, the detection of a
noise via a microphone, an electrical signal at a signal input, the manual operation of a button, etc.
Ethernet: The most common technology for communication within a wired network. It facilitates
data exchange between all devices (computers, printers, IP cameras, video phones etc.) connected
in a local network (LAN).
Flash memory: See MicroSD card.
Frame rate: The frame rate specifies how many frames per second (fps) are generated and sent
by the camera. From 16 fps smooth video sequences recognizable by the human eye.
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.
HiRes: Abbreviation for High Resolution. Refers to high-resolution images (above 1megapixel).
IP network: Data network based on the Internet protocol (TCP/IP).
IP telephone: See VoIP.
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
component 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.
Motion detection: Detecting a movement within a particular area. MOBOTIX cameras use algo-
rithmic methods to detect changes from image to image in predefined areas, while taking preset
conditions into account. If a camera detects a movement, it signals an event and triggers an alarm.
MxEasy: Free-of-charge MOBOTIX video management software for small and compact camera
networks of up to 16 cameras/door stations.
