When your building has a lot of people coming and going, you are going to need tools that will help you keep track of who is where. Intercoms are perfect for this level of security because you can interact with people at the door without having to move.

This also increases security because you don’t have to open the door until you have a clear idea of who you are letting in. Connect a door intercom to your system throughout the building so everyone in your organization can easily stay in touch.
