These systems offer huge advantages for office security while also supporting other operational functionality, like video calls. Your employees can communicate more effectively without a phone call or having to wait for an email response. The intercom systems can be installed along with a video doorbell and can allow visitors to speak while at the door. Administrators can verify visitors through video communications or audio messaging and then decide whether to let the person in. Integration with an access control system can restrict access to unauthorized intruders.

Wired vs. Wireless

When it comes to security, some may prefer wired connections, as each hub is hardwired to the next. This will make the system less susceptible to breaches into the system. Wireless connections on the other hand, rely on a network to communicate. Networks can be hacked if proper authentication is not provided. In terms of reliability, a wireless connection’s dependency on the battery or network can be a risk of shutdown, but the same can’t be said for wired connections. When it comes to ease of installation, however, wireless intercom systems are the easiest to install.

It provides an extra layer of security and can help to decide whether to let the person in. It can also be integrated with access control systems for enhanced security and control visitors’ access in the facility.


Doorbell & Buzzer Alerts

Instant alerts are sent to the admin or the responsible person(s) in the facility when the doorbell is pressed by a visitor.

Benefits of Door Intercom Systems


Communications & Announcements

Communication is the key in intercom systems. Seamless two-way communication between office employees and visitors makes the process easy and convenient. The speakers being placed at the strategic points in the building can make it easy for everyone in the building to receive a message at the same time. Announcements help to find the specific individual quickly.


Controlled Access Points

This feature restricts access to certain rooms within the facility. This ensures that only authorized personnel are allowed in high-priority areas.

Industry-specific intercom solutions

Intercom system needs vary based on industry. Some of the key industries are listed below:


Office buildings

Office Intercom Systems help in easy two-way communication between the office employees to perform immediate business operations. With the integration of access control, video surveillance systems help to provide unified security solutions for businesses. Utilizing biometric technologies like facial recognition provides easy access to the facility.


Commercial warehouse

A commercial warehouse intercom system is generally used for trying to get the attention of warehouse workers to deliver messages or to have one of them call back. Wireless intercom systems work better in this case because the wired connection may get damaged by the warehouse movement.

It’s always better to have a consultation with a logistics security consultant to get information on all the features and options.



These days, most schools have intercom systems. Schools should have high-security measures, and intercom systems play an essential role in granting visitors or other personnel access to enter the school building. Visitors can only be allowed when there is reasonable justification (ex. parents, guest speakers, etc.).



The manufacturing industry needs door intercom systems, not only for the screening of visitors in the building but also for carrying out smooth workflows. The intercom system can be integrated with access control, video surveillance, and other systems for enhanced security and productivity.



Secure healthcare facilities require constant communication for swift movement and to perform operations quickly. Intercom systems help to facilitate easy communication among staff in different wards and provide patient protection for security purposes. Personal safety and public assistance requirements are satisfied by intercom stations for lifts, car parking, and intercom equipped parking spaces solutions, which provide quick access to assistance in case of problems at pay-on-foot machines and vehicle barriers.
