Two sensors and a picture even in the dark
The manufacturer lists the resolution as 8+2 MP, meaning the camera uses two sensors of different resolution. How their views are split and what the exact video resolution is in pixels is not spelled out in the data. The 4 mm lens gives a narrower, more detailed view than wide 2.8 mm lenses and suits spots where you need to make out faces or number plates. At night the infrared illumination takes over with a reach of up to 30 metres.
