The Transmission Control Protocol (TCP) is a connection-oriented protocol
used to send data over an IP network. The TCP/IP protocol defines how data
can be transmitted in a secure manner between networks. TCP/IP is the most
widely used communications standard and is the basis for the Internet.
The process of transferring data in small amounts.
A subtype of schedule entity that supports both daytime and nighttime
coverages. A twilight schedule may not be used in all situations. Its primary
function is to control video related behaviors.
See also standard schedule.
Communication between a single sender and a single receiver over a network.
Uniform Resource Locator A URL (Uniform Resource Locator, previously Universal Resource Locator) is
the unique address for a file that is accessible on the Internet. The URL contains
the name of the protocol (http:, ftp:, file:) to be used to access the file resource,
a domain name that identifies a specific computer on the Internet, and a path
name, a hierarchical description that specifies the location of a file in that
computer.
unit
Unit discovery tool
Unit replacement
A hardware device that communicates over an IP network that can be directly
controlled by a Security Center role. We distinguish four types of units in
Security Center:
• Access control units, managed by the Access Manager role
• Video units, managed by the Archiver role
• LPR units, managed by the LPR Manager role
• Intrusion detection units, managed by the Intrusion Manager role.
See also access control unit, video unit, LPR unit, Access Manager, Archiver,
LPR Manager, and Intrusion Manager.
Tool that allows you to discover IP units connected to your network, based on
their type (access control or video), manufacturer, and network properties
(discovery port, IP address range, password, and so on). Once discovered, the
units can be added to your system.
Tool used to replace a failed hardware device with a compatible one, while
ensuring that the data associated to the old unit gets transferred to the new one.
For an access control unit, the configuration of the old unit is copied to the new
unit. For a video unit, the video archive associated to the old unit is now
associated to the new unit, but the unit configuration is not copied.
