Intercom security systems are used to manage access in a number of different applications, including:
Home intercom systems
Residents can use a front door wireless intercom or wireless doorbell intercom system to check the identity of visitors before opening a door. A 2-way wireless intercom system like this supports one-to-one communication. These devices are meant for a single door, without many of the security and usability features needed for a business or multi-family complex.
Intercom entry systems for multi-tenant residential buildings
There is usually one main access point (such as a lobby) and each occupant can connect to the main door to communicate with visitors using the apartment intercom system. Some higher-security multi-tenant buildings may also have a nominated person who controls access on behalf of the residents. Some residential apartment and condo buildings also allow tenants to give visitors access to amenity spaces, parking garages, elevators, and unit doors.
There is generally a single main locked entrance to a commercial office building covered by a business intercom system. Visitors request access by contacting a central point, such as reception or a security desk, or they may contact individual employees directly. An intercom security system can also be configured to allow out of hours access to be controlled remotely or from a central point.
In buildings such as factories or warehouses, access may be controlled by an intercom security system during working hours or when the facility is closed. Access for industrial buildings is likely to be managed by a security control room that monitors deliveries, visitors, and personnel.
Parking lots and garages
Car parks with restricted access have gates with outside intercom systems that enable visitors or authorized employees or residents to request entry. A touchless intercom system would be best suited for a car park.
Gate entry systems can be used to manage access to gated communities, industrial properties or larger areas where access is restricted. Gate intercom systems include a buzzer so that visitors can contact a security officer or a community resident to request access. Rather than requiring visitors to search through complicated directories, some modern intercom systems offer touchless, voice-activated call routing with keyless door entry.
Visitor management integration
Commercial buildings with large numbers of visitors can use an intercom unit or intercom door entry system integrated with a visitor management system, which can streamline access for authorized visitors. For example, occupants can provide authorization codes for visitors to use over the intercom. If the intercom access control system has built-in reader functionality, pre-authorized visitors could also scan a guest pass QR code to gain entry. This increases security and convenience.
Delivery management integration
The growth of online purchasing has increased the number of deliveries to both residential and commercial buildings. Integrating intercom access control systems with delivery management systems can also streamline deliveries. Similar to visitor management systems, occupants can provide delivery staff with access codes. With a mobile-based intercom system, delivery personnel can call the recipient directly to get delivery instructions, even if the person is not at the building.
In campuses with many buildings and many access points to manage and secure, individual intercom systems can be configured as part of an exchange intercom system. Individual base stations are connected to an exchange or central controller, which routes access requests to the appropriate substation. This approach ensures consistent standards of access control across the campus and reduces management complexity.
Integration with security programs
As well as providing standalone solutions for managing door entry, intercom systems can be integrated with your security technology by integrating them with security management or surveillance systems.
For example, in a commercial building, video-based door intercoms can connect visitors directly with employees, but the system can be configured to also provide security teams with a view of the door. Security teams can then identify issues such as attempts at forced entry or doors left open to allow tailgating. Door intercom security can also be integrated with audit systems so that security teams can review the performance of intercom systems and monitor any unusual patterns that might pose a security risk.
