Akuvox's 2-wire intercom and access control range brings together the components needed to build a complete entrance system over simple two-wire cabling. The range includes a video intercom nametag module, a SIP video door phone, a SIP single-button door phone, an Ethernet-to-2-wire adaptor, an IP access control terminal, a face recognition access control terminal, a Bluetooth access card and a four-door controller. Together they cover visitor calling, resident identification and door control, so one supplier can equip apartment buildings, offices and mixed-use sites. The 2-wire approach lets installers reuse existing cabling when upgrading older buildings, saving time and cost.
