Electronic doorman allows you to communicate with guests by gate or door by a telephone device attached to door units.

Electronic doorman connects to an electric lock controlled by a phone. It is also possible to use the electronic doorman to open main door, ramps, garage gates, or as a simple access system with a chip card, a key chain or a code.

Its door units can have an anti-vandal mode, more resistant to mechanic damage. There are three main types of the electronic doorman:

  • Analog doorman – older and simpler systems (almost without settings)
  • Digital doorman – modern audio and video doorman (less wiring, more settings)
  • IP doorman – the most advanced video doorman (the most settings, cell phone interconnection)
