The intercom is a stand-alone voice communication system intended for use in a multi-unit building to establish communication between a resident and the entrance to the property. The system operates independently of the public telephone network. Intercom systems are usually permanently installed in buildings and allow you to better manage visitor access to your building, greatly improving resident security.

Intercom systems are an essential tool for buildings, whether residential, commercial, or institutional, providing a safe and efficient method of managing visitor access. These systems function autonomously, detached from the constraints of the public telephone network, adding an extra layer of security. GMS Security’s intercom systems are permanently installed within buildings, offering an effective, user-friendly method to control visitor access. This not only enhances the security profile of the premises but also gives occupants peace of mind, knowing that access to their premises is well-regulated.

An entry intercom system facilitates communication between the resident and the visitor before entry is granted. This is especially relevant in larger cities such as Ottawa, where security in residential and commercial buildings is of utmost importance.


When opting for an entry intercom with cloud technology, it is now possible to establish video communication via a mobile application and give access to your building from anywhere in the world. It is also possible for a resident to issue temporary access to a visitor for a given period of time and to share this access with the visitor via the mobile application.
