Test lab finds improved storage when comparing company's 'Digital Pixel System' to CCD cameras using MPEG-4
Pixim, a maker of chipsets for video surveillance capture, announced today the results of independent tests on the company's compression algorithm.
The test lab, dBeetch Associates, found that Pixim's Digital Pixel System does indeed offer "significant compression advantages." Better compression, of course, allows more video surveillance data to be stored in an NVR/DVR, and according to Pixim, this proves that their Digital Pixel System helps lower overall costs for video surveillance by requiring less storage for the same amount of video.
The tests compared Pixim's system to high and medium resolution analog CCD cameras, and the test also compared the wide dynamic range capabilities of the Pixim technology. Three cameras, a Pixim camera, a high-res CCD camera and a medium-resolution CCD camera were used with the same lens to record the exact same scene over 24 hours. Data was recorded to the same DVR and all cameras were recorded with MPEG-4 compression.
Pixim is offering information on the tests, including a compression overview fact sheet, a technical whitepaper on the Digital Pixel System and a Flash-based flip book discussing storage savings that can be attributed to the company's compression technology. The information is available on Pixim's website, pixim.com.
