Intercoms – element of access control

Intercoms are important for security and access control situations where communication is necessary between different areas of a building or property. They provide a simple and efficient way for users to communicate with each other and allow for remote access control by enabling users to grant or deny access to specific areas. Additionally, integrating intercom systems with access control can enhance security and provide additional benefits such as continuous monitoring and event reporting.

The benefits of integrating an intercom system with access control include the ability to manage and monitor intercoms alongside other subsystems through a comprehensive security platform, the ability to place and terminate calls between desktop stations and remote intercoms, and the ability to trigger door openings from an operator’s desktop station and log this action as an event in the system. Other benefits include continuous monitoring of intercoms and event reporting in alarm monitoring, creating automated workflows based on intercom events, and triggering OnGuard actions based on received intercom events.

Take a closer look on two intercom systems enabling integration withLenelS2 OnGuard.

Interkomy Compatible 2N products integration Lenel OnGuard


The integration between LenelS2 OnGuard® system and 2N IP intercoms enables security operators to manage and monitor intercoms together with other subsystems through one comprehensive security platform. 2N provides a serverless solution of IP intercoms supporting direct SIP calls from 2N IP intercoms to the Master station, as well as calling via a central SIP proxy server.


Operators can place or terminate a call between their desktop station and selected remote intercom, or between different intercoms with a single click in the OnGuard system interface. It is also possible to trigger a door opening right from the operator’s desktop station and log this action as an event in the system.


In the Alarm Monitoring window, operators can see the intercom’s event, call states, SIP registration and connection status. Device control and monitoring are possible through the System Status Tree View or through the icons representing intercoms in the graphical maps.


Different intercom events such as call status, motion detection, tamper switch alarm, audio loop test can be monitored and further linked with actions in OnGuard to create automated workflows.

The integration of LenelS2 with 2N IP intercoms allows for increased security, gives security system operators the ability to easily manage and monitor intercoms, saving time and ensuring security for companies of all sizes.
