identify areas for enhanced processing. The camera
examines the scene using intelligent video analytics
and provides feedback to re-tune the image
processing. This provides better detail in the areas
that matter and better all-round performance. 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 imager 9000 HD
has excellent range performance when evaluated
according to these standards as shown in the
following table:

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
120 m (394 ft)

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.
Intelligent Video Analytics
The Bosch Intelligent Video Analysis (IVA) software is
the guard-assistant system of choice when reliable
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:
