2 | NDN-921 FlexiDomeHD 720p Day/Night IP Camera
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.
