The FlexiDome 2X Day/Night camera is the ultimate solution
for virtually any indoor or outdoor surveillance application.
This vandal-resistant dome camera uses a 1/3-inch, wide
dynamic range CCD sensor and incorporates advanced (20bit) digital signal processing for outstanding picture
performance.
The 20-bit image processing enhances sensitivity; the 2XDynamic extends the dynamic range. This unique
combination provides a sharper, more detailed image with
outstanding accuracy in color reproduction even under
harsh lighting conditions.
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, parking garages, retail and industrial
buildings.
Installation is quick and easy, as the camera comes
completely assembled and ready to use. Using the
proprietary pan/tilt/rotation mechanism, installers can
select the exact field of view. Mounting options are
numerous, including surface, 4S (USA), wall, corner and
suspended ceiling. The compact, sleek design and virtually
flush-mount appearance complements any decor.
The FlexiDome 2X camera is an ideal solution for many
surveillance applications, even under the most challenging
lighting conditions. The day/night feature ensures the
highest image quality possible at any time. Depending on
the available light the camera will automatically switch from
color to monochrome.
All FlexiDome cameras are supplied ready to operate. Six
distinct pre-programmed operational modes are stored in
the camera. Recall the mode that suits your application for
optimized performance.
Functions
Detail in Extreme Lighting
In harsh lighting, the difference between the brightest and
the darkest parts of a scene can be extreme. To produce a
clear picture in these conditions, the CCD sensor in the
FlexiDome 2X generates two images; one long exposure to
resolve details in the scene’s darkest areas, and one short
exposure to resolve details in the scene’s brightest areas.
The Digital Signal Processor (DSP) of the FlexiDome 2X
combines these dual shutter images, mixing pixels from
each exposure to produce the most detailed image
possible.
20-bit Image Processing
The highly accurate digital signal processing optimally
captures the detail in both bright highlights and deep
shadows simultaneously. By combining 20-bit image
processing and wide dynamic range, the FlexiDome 2X
maximizes the information visible in the picture even with
strong backlighting.
Wide Dynamic Range
The superior wide dynamic range handling for all lighting
conditions reveals details previously unseen.
2X-Dynamic and SmartBLC
Using 2X-Dynamic technology, pixel-by-pixel analysis
provides the user with the most detailed information. Turn
on SmartBLC to automatically compensate the image
without the need for complicated set-up or without
compromising dynamic range.
Detail Enhancement
Features such as Autoblack and Sharpness further improve
the details in a scene, pixel by pixel.
Day/Night Mode
The day/night mode provides enhanced night viewing by
increasing the IR sensitivity. The IR filter can switch from
color to monochrome automatically by either sensing the
illumination level or via the alarm input. The filter can be
switched manually via the alarm input, through the camera
menu or via the Bilinx coaxial control interface. An internal
through-the-lens IR detector enhances the monochrome
mode stability, as it prevents reverting to the color mode
when IR illumination is dominant. IR contrast is also
measured and used to handle reflected IR light in outdoor
scenes.
Privacy masking
Four different privacy zones allow specific parts of a scene
to be blocked. Pre-program any part of the scene to be
masked.
Default Shutter
The default shutter speed captures fast moving objects
when sufficient light is available. When light levels fall and
other adjustments have been exhausted, the shutter speed
reverts to a standard setting to maintain sensitivity.
Bilinx Technology
Bilinx is a bidirectional communication capability
embedded in the video signal of all Bosch FlexiDome
cameras. Technicians can check status, change camera
settings and even update firmware from virtually anywhere
along the video cable. Bilinx reduces service and installation
time, provides for more accurate set-up and adjustment,
and improves overall performance. In addition, Bilinx uses
the standard video cable to transmit alarm and status
messages, providing superior performance without
additional installation steps.
Ease of installation
Several features are available that make installation easy:
Video connection BNC on flying lead
•
Power connection on flying leads
•
A built-in test pattern generator produces signals to test
•
and fault-find cables.
A multi-language On-Screen Display (OSD) increases
•
user compatibility.
Programmable Modes
Six independent, pre-programmed operating modes
support typical applications, but are fully programmable for
individual situations. Switching between modes is easy via
Bilinx or the external alarm input.
High efficiency
A high efficiency power supply improves maximum
operating temperature.
Video Motion Detection
The built-in video motion detector allows you to select a
programmable area with individual thresholds. The global
scene change detector minimizes false alarms caused by
sudden lighting condition changes, such as switching on or
off the indoor or security lighting. When motion is detected,
alarms can be displayed in the video signal, the output relay
can be closed or an alarm message can be transmitted via
Bilinx.
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.
