MOBOTIX GLOSSARy
ActiveX:
Control element on Windows computers that may also be used in other programs (including
Internet Explorer) to run special tasks. The MxPEG ActiveX control element allows video and audio
data from MOBOTIX cameras to be displayed in other applications (including Internet Explorer).
Arming:
This refers to the process of activating an alarm system so that events trigger the appro-
priate alarms. Traditional alarm systems can be armed using a key switch or by entering a code
on a keyboard. MOBOTIX cameras can be armed using a “software switch.”
Assistant:
Refers to a software component that helps the user install or set up a particular program
and guides the user through the configuration process by means of simple questions.
CCTV:
Abbreviation for Closed-Circuit Television. A television system in which the analog video
signal is only transmitted to monitors (for example, within a building). The term CCTV is often
used for video surveillance systems.
CIF, 2CIF, 4CIF (according to the PAL television standard):
Common Intermediate Format. Corresponds
to 1/4 TV image with 288 rows and 352 pixels (0.1 megapixel). 2CIF (1/2 TV image) has the same
small number of rows (288), but 704 pixels (0.2 megapixel). 4CIF corresponds to the image quality
of a traditional TV image with 576 rows and 704 pixels (0.4 megapixel).
CMOS sensor:
Abbreviation for Complementary Metal Oxide Semiconductor sensor. Sensor for
energy-efficient digitalization of image information. CMOS sensors are used as image sensors
in digital cameras.
DHCP:
Abbreviation for Dynamic Host Configuration Protocol. Allows a server to automatically
assign devices in the network with the appropriate configuration (including the IP address, DNS
server and gateway), as opposed to static IP addresses on the individual network devices.
DNS:
Abbreviation for Domain Name Service. Allows the domain names of servers on the Internet
(for example, www.mobotix.com) to be linked ("resolved") to their corresponding IP addresses
(for example, 212.89.150.84).
DSL:
Abbreviation for Digital Subscriber Line. Denotes a fast Internet connection capable of provid-
ing bandwidth of up to 500 Mbps.
DynDNS:
Abbreviation for Dynamic DNS (or DDNS, Dynamic Domain Name Service). Similar to DNS,
this links domain names (e.g. mydomain.com) with IP addresses, whereby the IP addresses may
change at any time. This service provides a convenient method to access your MOBOTIX cameras
from home or work if the camera Internet connection is not through a router that assigns a fixed
IP address, but instead over a DSL connection with a dynamically assigned IP address from the
provider. A well-known provider of this (free-of-charge) service is www.dyndns.org.
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.
