camera or send E-mails. For that functionality Bosch Video Management System provides a
specific set of commands. Command Scripts are divided into Client Scripts and Server
Scripts. Client Scripts are used on client workstations to execute certain tasks that can run on
a client workstation. Server Scripts are executed automatically by an event that was triggered
in the system. They get arguments provided by the event like date and time. A Command
Script can consist of several scriptlets. You can create a Command Script using the following
scripting languages: C#, VB.Net. Command Scripts are executed in response to events or
alarms automatically according to a schedule (Server Scripts only), manually from the Logical
Tree, or manually from icons or on maps.
Compound Event
Combination of different events. The combination uses Boolean expressions, i.e. AND and OR.
You can combine only state changes, for example the change of a connection state to
disconnected or the activation of a schedule.
Compression See Video compression.
Configuration Client
Application used to configure Bosch Video Management System.
Database Collection of data that is organized so that its contents can easily be accessed, managed, and
updated.
Decoder Changes a digital stream to an analog stream, e.g., to display digital video on a analog
monitor.
Detection zone
Motion detection zone. A user defined template that watches for motion in a specific part of
the video image, as opposed to simply detecting motion anywhere in the image.
Device Hardware component such as encoder/decoder, NVR, DiBos, analog matrix, ATM / POS
bridge.
Device Tree Hierarchical list of all the available devices in the system.
Digital input An external device that interfaces with Bosch Video Management System providing an on/off
signal to the application. Bosch Video Management System can then use the digital input to
associate it with a pre-determined action. Digital input sources can include devices like door
contacts, motion detectors, card readers, etc.
Digital zoom Software manipulation of an image whereby the image is cropped and enlarged creating pixels
through interpolation.
DNS Domain Name System. A DNS server converts a URL (www.myDevice.com, for example) into
an IP address on networks that use the TCP/IP protocol.

Dual authorization
Security policy that requires two different users to log on to the Operator Client. Both the
users must be member of a normal Bosch Video Management System user group. This user
group (or these user groups if the users are members of different user groups) must be part of
a dual authorization group. A dual authorization group has its own access rights within Bosch
Video Management System. This dual authorization group should have more access rights
than the normal user group that the user belongs to.
