Glossary
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).
Dome camera
Camera generally of a round, compact shape: its lens can be directed and is protected by
a transparent dome housing.
DSL
Abbreviation for Digital Subscriber Line. Denotes a fast Internet connection capable of pro
-
viding bandwidth of up to 16Mbps for a typical household.
Dual dome camera
Dome camera with two lenses and image sensors such as the MOBOTIX D12D. These lenses
can deliver Wide Angle and Telephoto images independently of one another.
DVR
Abbreviation of Digital Video Recorder.
DynDNS
Abbreviation of Dynamic DNS (or DDNS, Dynamic Domain Name Service). Similar to DNS,
this links domain names (for example,
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’s Internet connection is
not through a router that assigns a static IP address, but rather via a DSL connection with
a dynamic IP address from the provider. A well-known provider of this (free-of-charge)
service is
www.dyndns.org.
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, etc.) connected in a local
network (LAN).
ExtIO
MOBOTIX signal module that the camera uses to directly operate lamps, sirens and door
openers, as well as external audio components (speakers and microphones).
