Property managers can hire a doorman who does everything from act as a security guard or concierge to a greeter—and who isn’t even present. The Virtual Doorman integrates interactive audio and video conferencing technology, access control systems, surveillance cameras, and the Web to control building access and provide security 24/7 via a secure Internet connection. Starting at $20,000 for installation and a monthly fee ranging from $500 to $2,500, depending upon the number of units and the level of additional service required.
