Bosch Appliances NDN-921 Home Security System User Manual


 
and user-friendly. The installer just needs to select a
mode from the menu that best defines the
environment in which the camera is being installed.
However, the operator still has the ability to customize
these modes, if necessary, for the specific
requirements of the site.
Day/Night switching
In night mode, the camera enhances low-light viewing
by switching the IR (infrared) filter out of the optical
path and providing a monochrome image. The camera
can switch from color to monochrome mode
automatically by sensing the illumination level, via the
alarm input, or remotely via a web browser. In scenes
with predominantly IR light, use the alarm input for
reliable Day/Night filter switching.
Privacy masking
Four different privacy zones allow specific parts of a
scene to be blocked. A mask for any part of the scene
can be pre-programmed.
Default Shutter
The default shutter allows the camera to use a higher
shutter speed when sufficient light is available (for
applications such as traffic management). When light
levels fall and other adjustments have been exhausted,
the shutter speed reverts to a standard setting to
maintain sensitivity.
SensUp Dynamic
By increasing the integration time up to 10 times on
the CCD, the effective sensitivity is dramatically
enhanced. This is especially useful when relying only
on moonlight for illumination.
Efficient bandwidth and storage management
The cameras use H.264 (Main Profile) compression,
bandwidth throttling, and multicasting capabilities to
manage bandwidth and storage requirements
efficiently, while delivering high image quality and
resolution.
Bosch's innovative Quad-streaming feature enables the
FlexiDomeHD to deliver three H.264 streams (a 720p
HD stream, a downscaled resolution stream, and a HD
I‑frame only stream) together with an M‑JPEG stream.
These four streams facilitate bandwidth-efficient
viewing and recording options as well as integration
with third-party video management systems.
FlexiDomeHD cameras offer unparalleled recording
options. Attached to the network, they can use iSCSI
targets directly without needing any recording
software. The recording management capabilities of
the system can be further enhanced by using the
Bosch Video Recording Manager (VRM).
FlexidomeHD supports local storage on micro SD card.
This can be used for local alarm recording or for
Automatic Network Replenishment (ANR) to improve
the overall reliability of video recording.
Standard intelligence
With built-in video content analysis, the camera
reinforces the Intelligence-at-the-Edge concept where
edge devices become increasingly intelligent. The
MOTION+ video motion analysis system, which is built
into all camera versions, is the perfect solution for
applications where basic video content analysis
features are required. This motion analysis algorithm is
based on pixel change and includes object size
filtering capabilities and sophisticated tamper-
detection capabilities.
Hardware enhanced version
The hardware-enhanced version of the camera gives
you the opportunity to upgrade the video content
analysis features of the camera with the more
advanced Intelligent Video Analysis (IVA) option. This
option contains such features as idle object, line
crossing, flow detection, crowd detection etc. The
camera can be ordered with IVA pre-installed from the
factory or IVA can be activated on hardware enhanced
versions by installing a license on-site.
ONVIF conformance
The camera conforms to the ONVIF (Open Network
Video Interface Forum) specification which guarantees
interoperability between network video products
regardless of manufacturer. ONVIF conformant devices
are able to exchange live video, audio, metadata and
control information. They are automatically discovered
and connected to network applications such as video
management systems.
Tough design
The cast-aluminum housing, polycarbonate dome, and
hardened inner liner can withstand the equivalent of
55 kg (120 lbs) of force. The enclosure contains the
full-featured camera and integral varifocal lens. Ideal
for outdoor use, the cameras are protected against
water and dust to IP 66 (NEMA 4X) standards. The
camera enclosure provides the extra protection
necessary for applications such as schools, banks,
prisons, retail outlets and industrial buildings.
Installation is quick and easy, as the camera comes
completely assembled and ready to use. The camera
uses Bosch designed lens and optics to deliver true
HD resolution with different light levels.
Using the proprietary pan/tilt/rotation mechanism,
installers can select the exact field of view. Mounting
options are numerous, including surface, wall, corner,
and suspended ceiling mounting. The compact, sleek
design and virtually flush-mount appearance
complements any decor.
Unsurpassed flexibility
There are many ways to access the camera’s video: on
a PC using a web browser, with the Bosch Video
Management System (VMS), or with the Bosch Video
Client. The Bosch Video Client is provided free of
charge with each camera. This easy-to-use software
can easily configure and operate up to 16 cameras. A
license upgrade adds support for up to 64 cameras.
