Six megapixels from a wide angle
The 3288 × 1850 resolution has a 16:9 aspect ratio and adds up to about six million pixels. The extra pixels pay off when you need to zoom into a recording to make out a face, clothing or a vehicle. The 2.8 mm lens is a wide-angle one: a whole room, lobby, corner of a car park or a front entrance together with its steps fits into the frame.
