Light levels and reflectances in typical environments.

Resolution is similar in the analogue or digital worlds, but there are important differences in how it is defined.

Fundamentally different networks are merging into one IP network. In these networks, it is necessary control shared network resources.

CCD (Charged Coupled Device) and CMOS (Complementary metal oxide semiconductor).

CCD In addition to good light sensitivity, another key feature of digital image capture is progressive scan technology.

The range of lighting from bright sunlight to clear starlight is 10⁹:1 (100,000,000):1.

The Axis 221 features an automatic, removable infrared-cut filter, which enables the camera to provide colour video when there is sufficient light, and black and white video in dark conditions.
