Despite inflammatory media accounts proclaiming the end of the megapixel race in the security industry, recent conversations with camera OEMs suggest otherwise. In fact, camera companies appear poised to up the ante and move forward with plans to increase camera resolution, following the lead of cell phone and digital camera companies before them. Nokia, for example has come out with their 41 megapixel cell phone camera. While the camera may indeed provide 41 megapixels of native resolution, the image resolution is likely limited by the lens. Without a good megapixel lens, the claims of multi megapixel resolution are just so much marketing hype. With so much hype in the news, it is helpful to clarify how resolution is defined and what factors determine image resolution.
