Independent tests confirm: Pixim Digital Pixel System® technology offers significant compression advantages
Pixim Inc,
a leading provider of image sensors and processors for enterprise
security cameras, announced that research performed by an independent
test lab has validated significant compression advantages (along with
associated cost, storage and file transfer benefits) of Pixim’s Digital Pixel System® technology.
The tests, conducted by dBeech Associates Ltd (www.dBeech-Associates.com),
validated the Digital Pixel System technology’s superior compression
capabilities and digital video recorder (DVR) space savings in some
typical security applications, compared to both high-resolution and
medium-resolution analog CCD cameras. In addition to the compression
advantages, the independent test lab also confirmed the superiority of
the true wide dynamic range (WDR) capabilities of Pixim’s Digital Pixel
System technology.
To provide further information on the
compression advantages of Pixim-powered cameras, Pixim has developed a
library of information available on its website.
Included are...
♦ A Compression Overview fact sheet.
♦ A technical white paper Compression Advantages of Pixim’s Digital Pixel System® Technology
outlining how Pixim’s Digital Pixel System technology is able to
deliver compression advantages for users of video security systems.
♦ A Flash flip book Storage Savings With Pixim-powered Cameras that is Volume 3 in The Pixim Chronicles series of flip books.
John Monti, vice president of marketing and business development at Pixim said:
"Most of the advantages of Pixim’s innovative Digital Pixel System
image capture and processing technology are clearly visible: video
images with high resolution, natural color and superb accuracy, and
free of image compromising visual noise, regardless of a scene’s
lighting conditions. Less obvious, but equally impressive, is the fact
that Pixim’s all-digital technology produces images that are more
efficiently compressed. Efficient compression means that those
high-quality images are delivered in smaller file sizes, which can
dramatically reduce the costs of moving and storing security video in
both CCTV and IP-networked installations"
In the
dBeech Associates study, three cameras (one Pixim-powered, one
high-resolution analog CCD and one medium-resolution analog CCD) used
the same lens to capture the same scene over the same 24-hour period,
recorded by the same DVR using MPEG-4 compression. Although test
results naturally vary by application and scene content, this
independent testing showed a clear compression advantage for the
Pixim®-powered camera ~ requiring less hard drive space in the DVR to
store an equivalent amount of video content.
In addition to the
independent test lab results, Pixim’s internal tests as well as reports
from customers using Pixim-powered video cameras have consistently
found significant savings in disk recording space when comparing
Pixim-powered cameras to analog cameras on MPEG and H.264 DVRs. To cite
one customer example, an analog CCD video required up to three times
the disk space of a Pixim-powered video to record the same indoor
office scene.
Pixim’s Digital Pixel System
technology delivers video that is easier for compression algorithms to
work with to achieve higher compression rates without sacrificing image
quality. At a system level, this means higher flexibility and lower
costs because Pixim’s more efficiently compressed video images have
lower bit rates and smaller file sizes, which makes them easier to move
between the camera and a DVR or networked video recorder (NVR) and more
economical to store.
The ability to store the same mount of
video content in less DVR or NVR storage space means that video
security system operators gain tremendous flexibility in how they can
use that additional space to achieve optimum benefit from their
security system and reduce their total cost of ownership.
