Sometimes a doorbell or loud ringer just doesn’t do the job.
A door intercom unit installed at a front, side, or rear entrance allows your staff to answer that door from any phone on the phone system. These doors can now be kept locked to avoid potential security risks. And by installing an electric door strike with a door intercom unit you can also have the ability to remotely unlock the door once the party has identified themselves. Additionally, you may allow your employees access by way of a keycard, key fob, or numeric pass code.
