Megapixel network camerash1>

Megapixel network cameras, available in Axis’ fixed cameras and fixed dome cameras, incorporate a megapixel image sensor to deliver images with one million or more pixels. This is at least two times better pixel resolution than what can be provided by analog cameras.

A megapixel, fixed network camera can be used in one of two ways: it can enable viewers to see greater details in a higher resolution image, which would be helpful in identifying people and objects, or it can be used to cover a larger part of a scene if the image resolution is kept the same as a non-megapixel camera.

Megapixel cameras today are normally less light sensitive than a non-megapixel network camera. The higher-resolution video streams generated by a megapixel camera also put higher demands on the network bandwidth and storage space for recordings, although this can be mitigated by using the H.264 video compression standard.
