with him using a microphone and speakers / headphones. The Client can control the electronic
door lock and some other devices connected to the door station controller.

are often downloaded and installed automatically as required.
Asymmetric Digital Subscriber Line (ADSL) is an obsolete type of Digital Subscriber Line
technology, a data communications technology that enables faster data transmission over copper

Angle is the field of view, relative to a standard lens in a 35mm still camera, expressed in
degrees, e.g. 30°. For practical purposes, this is the area that a lens can cover, where the angle of
view is determined by the focal length of the lens. A wide-angle lens has a short focal length and
covers a wider angle of view than standard or telephoto lenses, which have longer focal lengths.
