Any network security camera that has the megapixel label in its specifications refers to the type of image sensor built into the camera. Megapixel image sensors are special because they can produce images with at least one million pixels. This offers a resolution that is, at minimum, twice the resolution a traditional analog security camera can provide.
The megapixel network security camera offers more than a typical security camera in field of view. A megapixel camera can provide a highly detailed image that can be useful for jobs like recognizing faces or reading a license plate. If the resolution of the image is not used to pull a high level of detail, then the megapixel camera can cover a larger area in a single shot than a non-megapixel network security camera would.
