and the VRM into this initiator group. Only the devices whose initiator names are added to an
initiator group are permitted to access a LUN. See LUN and see iSCSI.
iSCSI Internet Small Computer System Interface. Protocol that manages storage via a TCP/IP
network. iSCSI enables access to stored data from everywhere in the network. Especially with
the advent of Gigabit Ethernet, it has become affordable to attach iSCSI storage servers
simply as remote hard disks to a computer network. In iSCSI terminology, the server providing
storage resources is called an iSCSI target, while the client connecting to the server and
accessing the resources of the server is called iSCSI initiator.
IVA Intelligent Video Analysis. Algorithm that detects specific properties and the behavior of
objects in a scene monitored by a video camera and from this generates alarm events that, in
turn, can be processed in a CCTV system.
Recording with IVA settings activated is a precondition to be able to selectively and quickly
search through video material later.
IVA makes it possible to capture and evaluate directional movement of objects in such a way
that false alarms are prevented to a large extent.
IVA adapts automatically to changing environmental conditions and is therefore largely non-
sensitive to perturbing influences such as rain and tree movement.
Especially when used for forensic search, IVA allows for filtering moving objects by their color
specifications. With the aid of IVA algorithm extensive video material can be searched
selectively for objects with specific color properties.
IVMD Intelligent Video Motion Detection. Software algorithm that detects moving objects within an
environment monitored by a video camera and generates alarm events that can be processed
further in Bosch Video Management System.
IVMD makes it possible to capture and evaluate directional motion of objects, thereby largely
preventing false alarms.
IVMD adapts automatically to changing environmental conditions and is therefore non-
sensitive to perturbing influences such as rain and moving plants.
Kbps Kilobits per second, a measure of data transfer speed.

LAN Local Area Network.
LDAP Lightweight Directory Access Protocol. Network protocol running over TCP / IP that allows
accessing directories. A directory can be for example a list of user groups and their access
rights. Bosch Video Management System uses it to get access to the same user groups as MS
Windows or another enterprise user management system.
LIFO Last in first out. Mode in the alarm handling of Bosch Video Management System that defines
the order of active alarms with the same priority.
Local Storage
On encoders with local storage, recording is performed block-wise, i.e. the data is stored in
blocks that are pre-allocated. When one block is filled up, the device continues to write the
next block. When all blocks are filled up, the blocks are overwritten. Local storage devices
support multiple partitions of arbitrary size that are considered as blocks.
