The DoorCom Industrial-Grade Wireless Intercom installs easily at any entry point to permit visitors to announce their arrival. The long-range performance allows radio-equipped personnel to receive a call from practically anywhere in the building and instantly answer back using a portable 2-way radio or desk-top base station. Applications include delivery/receiving door, employee entrance, entrance or lobby, will-call/pick-up, loading dock, factory floor, and more. It can increase efficiency and help maintain security by allowing exterior doors to remain locked. Workers can stay focused and productive until they receive an intercom call with a unique call-tone. Wasted time is reduced and deliveries and pick-ups are handled more quickly.
