Bosch Video Management System
RAID Redundant array of independent disks. Used for organizing two or more hard disks as if they
were one drive. On such a drive data is shared or replicated. This is used to achieve greater
capacity, reliability, and speed.
Recording quality
An adjustable setting for encoders (cameras). The slider range reflects the degree of
compression used by the encoder when encoding/compressing the video signal. Setting the
slider to the left lets the encoder use as much compression as possible (reducing the
bandwidth requirements, file sizes and picture quality). Setting the slider to the right lets the
encoder use as little compression as possible (increasing the bandwidth requirements, file
sizes and picture quality).
Recording Schedule
Used for scheduling recording and for scheduling some events like starting backup or limiting
log on. Recording Schedules cannot have gaps or overlaps. It also determines the video
recording quality.
Recording settings
Can be set in dependency on the Recording Schedule and the state of the camera. The
following states are possible: recording disabled, manual recording, continuous recording,
motion recording, alarm recording
Redundant NVR
Computer in the Bosch Video Management System environment. Records the same video and
audio data as the Primary NVR. A Primary NVR can have maximum one Redundant NVR.
Reference image
A reference image is continuously compared with the current video image. If the current video
image in the marked areas differs from the reference image, an alarm is triggered. This allows
you to detect tampering that would otherwise not be detected, for example if the camera is
turned.
Rewind time
Number of seconds in the past when an Image pane is switched to instant playback.
RFC Request for Comment. One of a long-established series of informal informational documents
and standards that guide the development of the Internet.
RMon Remote Monitoring. Standard for collecting statistical data from network devices for network
management purposes.
RTSP Real Time Streaming Protocol. A network protocol which allows to control the continuous
transmission of audio-visual data or software over IP-based networks.
Silent alarm Alarm that puts cameras into alarm recording mode but causes no other alarm responses.
These alarms are shown in the Event List, but do not appear in any Alarm Lists.
Site User-created entity for grouping related system resources together for ease of viewing and
management. Typically, a site corresponds to a physical location, like a building or a floor, but
it may be used to represent any concept.
SNMP Simple Network Management Protocol. IP based protocol that allows to get information from
networking devices (GET), to set parameters on network devices (SET) and to be notified
about certain events (EVENT).
