Home intercoms can connect to electric door locks, gates, and openers through configurable switching relays, allowing users to release an entry from an indoor station, smartphone, tablet, or compatible phone. Network-based models can integrate with existing smart home and security systems through Ethernet or Wi-Fi, open APIs, SIP, and interfaces such as Wiegand, OSDP, or RS485, depending on the system.

Plan for a suitable flush-mount or surface-mount location, Ethernet cabling with Power over Ethernet (PoE) where supported, and wiring to an electric door or gate release if access control is needed. Some home intercoms also support Wi-Fi, while indoor stations may require wall or gang-box mounting, so confirm network coverage, available power, mounting depth, and connection points before installation.

Video home intercoms can send notifications to a resident’s smartphone or tablet when someone presses the call button, allowing them to view live video and speak with the visitor remotely. Depending on the system, residents can also unlock a connected door or gate through the app while away from home.

Choose a flush-mount home intercom when you want the unit recessed into the wall for a low-profile appearance and have suitable space for the mounting housing. Choose a surface-mount home intercom when you need a simpler installation on an existing wall or when the wall does not accommodate a recessed housing.
