Testing Panasonic's Megapixel Camera (WV-NP502)

Author: John Honovich, Published on Feb 01, 2010

In this test, we examine's Panasonic WV-NP502 megapixel camera. The camera provides a number of advanced features including wide dynamic range optimization (their Super Dynamic technology), facial detection, image stabilization and more. The WV-NP502 is a high end model from Panasonic's broad range of professional and consumer/SMB network cameras.

We tested the Panasonic WV-NP502 with the WV-LZA62/2 lens connected to Exacq's VMS software using both MJPEG and H.264 streams, with Super Dynamic on and off and with other advanced features (facial detection, auto back focus, image stabilization, etc.).

Our key findings include:

  • Extensive advance features and image optimizations available. Users should carefully consider which they can use and the practical benefits of using
  • During day, solid picture quality; With low light (under 1 lux measured), video tends to be dark but minimal noise
  • Super Dynamic (SD) provided notable quality improvements in WDR environments; however night time performance decreased with the setting on
Closest comparisons in our testing so far include the Pelco Sarix cameraSanyo HD4000 and Axis Q1755. Additionally, compare to other megapixel camera tests in our video surveillance testing program.
