Intercom systems are used for the screening of visitors before they enter a premise.
They can offer 2-way audio communication and 1-way video verification. The basic concept is simple; a visitor presses the ‘call’ button at the door station to signal their arrival. The occupants respond by communicating with the visitors at the audio (and video) handset, then releasing the door with a simple push of the button from their tenancy. This releases the electronic lock (or opens the gate) which allows the visitor to access the building or compound.
Intercom systems can be used for single-tenanted applications with just one door station, multi-tenanted residential properties with multiple door stations and handsets, and even accommodating a concierge station for 24-hour staff.
