Common Problems
with traditional CCD security Cameras
1. CCD security cameras have
the inability to capture highlight and shadow detail in the same scene.
In traditional
CCD cameras all the pixels in the array have the exact same shutter
speed. This “one
pixel fits all” approach is a big problem.
As a result every pixel in an analog CCD
camera receives the exact same exposure, creating overexposed regions
in bright areas and underexposed regions in dark areas.
In a CCD all the pixels in the array have
the same shutter speed just
one aperture.
With Pixim the pixels in bright areas
automatically adjust to eliminate overexposure. Pixels in dark areas
automatically adjust to eliminate underexposure.

2. CCD security cameras
produce inconsistent clarity in bright, lowlight, or high contrast
situations.
Traditional CCD
cameras can’t see well when lighting conditions are not optimal. These cameras experience a
lack of details in high-contrast and backlit situations, low clarity
shadows, and image “washout” from glare or reflections.
Images with these cameras are always suspect.
3. CCD security cameras
create color inaccuracies in varying lighting conditions.
CCD
security cameras have a difficulty adjusting for proper white balance. Since they have a
difficult time finding the proper white balance it is difficult to
produce accurate colors in the video images.
4. CCD security cameras also
have difficulties with glare from windows and other reflective surfaces.
This goes back
to the basis of the technology mentioned above.
Since the CCD sensor has the same exposure
across the whole array the camera is not able to adjust for the
variation in lighting.
5. CCD security cameras can
suffer from camera blindness caused by vertical smear and pixel
blooming.
Pixel blooming
is a problem inherent in analog CCD technology.
(Click here to read
related article.) This
problem creates additional artifacts in the images which can distort
the images and cause blindness in areas of the camera sensor which can
seriously compromise the quality of the image.
6. CCD security cameras
create low quality recordings and large file sizes.
CCD cameras
frequently introduce a number of variants of random pixel alteration,
called “noise.” They
produce pixel blooming, vertical smearing and camera blindness which
can seriously reduce the quality of the image.
Noise
not only compromises image quality, it uses up valuable recording space. Analog CCD cameras can add
sampling and conversion noise that often increases DVR storage needs by
three times what GSP America cameras powered by Pixim require. Again this is a result of
how the technology works.
Pixim’s
patented Digital Pixel System (DPS) technology marks a fundamental
breakthrough
in imaging technology.
Building upon
technology developed at Stanford University in the 1990s, Pixim has
created an image capture and processing system that provides
high-quality pictures with enhanced dynamic range.

Side by Side
Examples
Reasons
why you should buy GSP America cameras powered by Pixims Digital Imager
1. GSP America cameras
powered by Pixims Digital Pixel System provide unparalleled image
quality across all lighting conditions.
Using wide
dynamic range (WDR) technology GSP America and Pixim deliver
unprecedented image quality, even in unpredictable and variable
lighting conditions.
2. GSP America cameras
powered by Pixims Digital Pixel System produce color that is true and
trustworthy.
CCD cameras,
because they generalize pixel settings, can not capture true color. They often deliver
saturated highlights or muddy shadows.
In contrast, GSP America cameras powered by
Pixim deliver accurate white balance and color that is true, so
security professionals will know the truth.
3. GSP America cameras
powered by Pixims Digital Pixel System give the highest total
resolution.
GSP America
cameras powered by Pixim deliver the highest total resolution. No other cameras offer 540
Horizontal TV Lines by 460 Vertical TV Lines from a progressive scan
imager.
4. GSP America cameras
powered by Pixims Digital Pixel System produce noise-free images.
The all digital
technology automatically eliminates mage-compromising visual
noise such as vertical smearing and camera blindness to ensure the
cleanest images available.
5. GSP America cameras
powered by Pixims Digital Pixel System save valuable disk space.
The
technology creates significant system savings.
You can record at up to 3x the resolution and
frame rate without increasing the DVR recording duration. (note: the size of the
benefit depends on the DVR, lens and other factors.)

Other reasons
Reliability – You can
count on GSP America cameras powered by Pixim to deliver clear,
accurate images. From retail stores to banks to Olympic stadiums,
Pixim’s Digital Pixel System technology provides the complete picture,
down to the crucial details so all the information is there when it’s
needed. Data
without doubt! GSP
America backs up that reliability with a full Two Year warranty on all
cameras powered by the Pixim Digital Imager.
Ability
to handle variable lighting – GSP America
cameras powered by Pixim are not foiled by changes in lighting, making
them ideal for any application. The
dynamic range in a Pixim-powered camera is an amazing 17 bits,
>100dB.
Highest
resolution and more natural color – GSP America
cameras powered by Pixims Digital Pixel System technology deliver the
highest total resolution at 540 Horizontal TV Lines by 460 Vertical TV
Lines, as well as superior color rendering.
As a result, target detail can be detected
accurately.
Lowers
overall system cost – GSP America
cameras with Pixim’s technology, compared with CCD technology enables a
higher compression of images. This
allows DVRs to record with higher frame rates and resolution while
maintaining the same total recording time.
Saving valuable disk space saves valuable
money.
