The traditional answer was simple: intercoms handle communication, access control handles entry verification. But that distinction is increasingly obsolete. Today's intercom systems often come with robust access control features like PIN codes, QR codes, proximity card readers, and facial recognition built right in — making it possible to get both in a single device.
How Modern Intercoms Have Evolved with Access Control Features
Contemporary video intercoms can include keypads for PIN code entry, QR code scanning, facial recognition, and proximity card readers — capabilities that once required separate, dedicated access control hardware.Take QR code access as an example. A visitor with a QR code on their smartphone simply holds it up to the intercom's camera, and the door or gate opens automatically — provided the intercom is connected to an electric door strike or automatic gate opener. Both PIN codes and QR codes can be configured for permanent or temporary access, and usage can be restricted to specific times of day. The video component adds another layer of security, allowing visitors to speak directly with staff or security personnel before entry is granted.
What Access Control-Intercom Solutions are Available for Multi-Tenant Properties?
For apartment buildings, condominium complexes, and multi-tenant commercial properties, there are intercom systems that go even further. These units can combine facial recognition, QR code scanning, PIN codes, and proximity card readers in one device. They also offer Wiegand compatibility, allowing integration with additional access control hardware such as RFID card readers, biometric scanners, and external keypads — giving property managers a highly scalable, customizable solution.What Connectivity Options are Available?
Modern access control intercoms support multiple communication technologies — cellular, Wi-Fi, or CAT-5 ethernet — so you can choose the connectivity method that best fits your infrastructure and environment.The Bottom Line
You no longer have to choose between communication and access control. Today's intercom systems can deliver both.
