in the areas that matter and better all-round
performance. With IVA, the intelligent Automatic
Exposure (iAE) technology, for example, allows you to
view moving objects in bright and dark areas of a
scene.
High performance IR illumination
The integrated high-power infrared illuminator
operates at a wavelength of 850 nm which provides
semi-covert illumination with an excellent range. IR
intensity is remotely adjustable. The illuminator can be
tilted, and the width of the IR beam is adjusted by
placing the 3D diffuser in the IR illumination path. This
ability to adjust the IR beam pattern in the field gives a
broad coverage and greatly reduces setup time and
effort. Variable field illumination also provides even
illumination not only across the horizontal field of view
but also from foreground to background.
IR on/off and camera day/night switching is controlled
by the image brightness level and the ambient visible
light sensor. The switch point is also remotely
adjustable.
To ensure this performance never fades over time, the
IR imager features constant light technology, using
closed-loop feedback to control infrared performance
throughout the life of the unit.
Excellent DCRI performance
The Detection, Classification, Recognition,
Identification (DCRI) framework is a set of definitions
for image quality applicable to optical imaging
equipment under different lighting and environmental
conditions day and night. The DINION IP imager 9000
HD has excellent range performance when evaluated
according to these standards as shown in the
following table:
IR performance ranges (0 lx environment)
Detection 120 m (394 ft)
Classification 120 m (394 ft)
Recognition 33 m (108 ft)
Identification 30 m (98 ft)
DCRI values are narrow IR beam configuration at maximum focal length.
Installer friendly
The IP66-rated waterproof and dustproof junction box
can be preinstalled and the camera can be hung and
connected in seconds, reducing time and energy on
the ladder. If PoE+ power is used, a single cable is all
that is needed to stream images and to carry power
and control signals.
The AVF (Automatic Varifocal) feature means that the
zoom can be changed without opening the camera.
The automatic motorized zoom/focus adjustment with
1:1 pixel mapping ensures the camera is always
accurately focused. The automatic zoom/focus lens
wizard makes it easy for an installer to accurately
zoom and focus the camera for both day and night
operation. The wizard can be activated remotely from
the PC or from the on-board camera push button
making it easy to choose the workflow that suits best.
All-weather, vandal-resistant design
The integrated cast-aluminum housing can withstand
the equivalent of 20 joule of impact force (IK10),
equivalent to a 5 kg (12 lbs) steel ball dropped from
40cm (IK10 not for lens and IR windows), and is
protected against water, dust and corrosion to IP66
and NEMA 4X standards.
This makes it ideal for outdoor use in demanding
environments. Using the proprietary pan/tilt
mechanism, installers can select the exact field of
view. Mounting options are numerous, including pole,
wall and corner mounting.
Video analytics
With built-in video content analysis, the camera
reinforces the Intelligence-at-the-Edge concept where
edge devices become increasingly intelligent.
The latest generation of the Bosch Intelligent Video
Analysis (IVA) software is the guard-assistant system
of choice when reliable indoor or outdoor video
analytics is needed. The state-of-the-art system reliably
detects, tracks, and analyzes moving objects while
suppressing unwanted alarms from spurious sources
in the image.
The face detection feature detects faces in the scene
and forwards a high quality JPEG image of the best
shot of each face when the face disappears from the
scene.
Retrospective forensic search capabilities are available
remotely from the web browser or the Bosch Video
Client.
iDNR reduces bandwidth and storage requirements
The camera uses intelligent Dynamic Noise Reduction
(iDNR) which actively analyzes the contents of a scene
and reduces noise artifacts accordingly.
The low-noise image and the efficient H.264
compression technology provide clear images while
reducing bandwidth and storage by up to 30%
compared to other H.264 cameras. This results in
reduced-bandwidth streams that still retain a high
image quality and smooth motion. The camera
provides the most usable image possible by cleverly
optimizing the detail-to-bandwidth ratio.
Area-based encoding is another feature which reduces
bandwidth. Compression parameters for up to eight
user-definable regions can be set. This allows
uninteresting regions to be highly compressed, leaving
more bandwidth for important parts of the scene.
The average typical optimized bandwidth in kbits/s for
various image rates is shown in the table:
IPS 1080p 720p 480p
30 1600 1200 600
15 1274 955 478
