Q24M Camera Manual: MOBOTIX Glossary
DynDNS
Abbreviation of 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 , which
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) service is www.dyndns.org.
Ethernet
The most common technology for communication within a wired network. It provides for
data exchange between all devices (computers, printers, IP cameras, etc.) connected to a
local area network ( »LAN ).
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 can 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.
ExtIO
MOBOTIX expansion module that the camera uses to directly operate lamps, sirens and door
openers as well as external audio components (speakers and microphones).

human eye perceives movement as a fluid video sequence when more than 16 images per
second are produced.

files over the Internet. MOBOTIX cameras are using FTP to update webcam images on web
servers, for example.
