A visitor calls
They press a button or select the unit or recipient from an available directory.
02 / Intercoms
See who is visiting, speak with them and release the door from a designated station or remotely when the system supports it.
The basics
An intercom connects a visitor with someone authorized to answer. Audio models enable conversation; video models also show the entrance. A command may then release a compatible strike or lock. The intercom does not replace the door's locking hardware. The number of units or recipients, the door and the available wiring all influence the choice of system.
They press a button or select the unit or recipient from an available directory.
An indoor station, reception desk or compatible app receives the call. Video depends on the model.
After checking the visitor, you can command the door to unlock if that feature has been installed and enabled.
Day to day
Good to know · 01
A multi-unit system can route calls to occupants and simplify directory updates. Decide who maintains the names, how calls are delivered and what happens when a resident does not answer.
A secondary or delivery entrance can stay controlled while visitors contact staff. Set up recipients by schedule, and establish who can release the door after confirming the reason for a visit.

Some systems use an indoor monitor; others use a phone connection or app. Remote operation depends on the network, accounts and sometimes a subscription. Also check what happens if the Internet connection or recipient's phone is unavailable.
Device placement, lighting, background noise and exposure to weather affect everyday use. The directory should be readable and controls accessible. Choose the location with the people who actually use the entrance in mind.
Choosing the right system
As one example, Hikvision's DS-KH6320Y-WTE2 monitor documentation describes call answering, video viewing and remote door release through Hik-Connect. These features require a compatible, correctly configured installation. Confirm the entrance panel, lock control and services for each project.
A retrofit starts by inspecting existing conductors, cable runs, power and the number of recipients. A two-wire design may suit some projects, but it requires compatible components. The chosen system also needs practical user management and maintenance. Do not assume that all old wiring can be reused.
Frequently asked questions
Yes, with certain systems and compatible services. Confirm phone answering for the equipment you choose.
Not necessarily. Live video, event history and recording are separate features. Check the available options and retention rules.
Depending on the system, a reader can be built in or installed separately. Residents or staff then use credentials, while visitors call through the intercom.
Technical reference: manufacturer documentation. Features depend on the equipment and its configuration.
