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.

"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," said John Monti, vice president of marketing and business development, Pixim. "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.
