DevKit
Camera installation kit with independent image sensors based on MOBOTIX M12D or M24M,
intended for concealed installation in other devices.
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 fixed 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
Most often refers to cameras with a round and compact design. The lens can be freely
positioned and is protected by a transparent dome-shaped plastic housing.
DSL
Abbreviation for Digital Subscriber Line. Denotes a fast Internet connection capable of
providing bandwidth of up to 16 Mbps for a typical household.
DualDome
Dome camera with two lenses and image sensors such as the MOBOTIX D14D. These lenses
can deliver wide angle and telephoto images independently of one another.
DVR
Abbreviation for Digital Video Recorder.
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.
Ethernet
The most common technology for communication within a wired network. It facilitates
data exchange between all all devices (computers, printers, IP cameras, etc.) connected in
a local network (LAN).
Events
An event refers to a situation when something happens or changes. In terms of video surveil-
lance, 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.
