Installed at the entrance where visitors request access, the outdoor call station can include a built-in camera, two-way communication, night viewing, a call button and multi-unit calling, depending on the selected equipment. Outdoor equipment should be selected according to the actual installation environment and manufacturer specifications.

Indoor monitors give occupants an interface for handling visitor calls: view and speak with the visitor, answer incoming calls, release a compatible door or gate and view supported entrance cameras, depending on the selected system. Compatible IP video intercom systems can extend this to supported mobile applications for villa owners, office managers, reception personnel, property managers and authorized residents. Remote functionality depends on the selected hardware, application, network connectivity and system configuration.
