Megapixel technology enables network cameras to provide higher resolution of video images than analog CCTV, i.e. the ability to see more details or have a wider coverage – a key consideration in video surveillance applications. With megapixel network camera's, the resolution is usually 4x better than an analog CCTV camera and often times 15-20 times better. For example, the highest resolution typically found in analog cameras is 640x480 or 307K pixels (.3 megapixels). The baseline megapixel camera is 1.3 megapixels or 4x that of analog. Take a 4 megapixel camera registering a 2032x1920 resolution. It has roughly 13x the resolution of a standard analog camera. Combining megapixel network cameras with a selection of non-megapixel network cameras that are optimized for other needs (such as powerful optical zoom, extreme light sensitivity or low cost) creates video surveillance...
