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.

Ethernet

Ethernet is the most widely-used LAN technology. Twisted-wire pairs with special quality

features are normally used for Ethernet LANs. The most widely-used Ethernet systems are

10BASE-T and 100BASE-T10, which enable data transfer rates of up to 10 Mbps and 100 Mbps.

Factory Defaults

These are the settings with which a device leaves the manufacturer’s factory when it is

shipped. If it is necessary to restore a device to its factory defaults, all the settings changed

by the user will usually be lost.

fps

Abbreviation for frames-per-second. See Frame rate.

Frame Rate

The frame rate speciﬁes how many frames per second (fps) are generated and sent by

the camera. 16 fps and higher is perceived by the human eye as a ﬂuid video sequence.

G.711

The process or processes by which analog audio signals are encoded and decoded. This

codec (= enCOder-DECoder) is used in classic telephone systems and in IP telephony.

H.264

The processes by which the video image is coded, compressed and decoded.

HDTV

Abbreviation for High Deﬁnition TV, which has a much higher resolution than conventional

TV signals.

HiRes

Abbreviation for High Resolution. Refers to high-resolution images (above 1 megapixel).

Illumination

In general, a camera does not require additional lighting for use in daylight. However,

some basic rules must be observed for use in the dark or under artiﬁcial light. A suitable

light source or supporting lighting must be selected depending on whether a general

overview is required or whether people or objects have to be accurately identiﬁed.
