Intercom Systems

Whether you need to manage the security of a small to medium sized building or a large apartment complex with hundreds of units, the basic idea of an intercom system is that such a system allows the user to communicate with his or her visitor at an entry door or entrance gate, so that the user can check who wants entry. 

Communication is established between the intercom system and either a landline telephone at the unit or even a cellular phone, which is most commonly used in multi-storey residential buildings. Or such a system uses the Internet to establish communication.

Most systems have built-in cameras that even allow the user to see the visitor, giving the user another method of verification before opening an entrance door or gate. The user can grant his or her visitor access to an entrance door or gate via an app on his smartphone or tablet. Integrated into a video surveillance system, every visitor can be recorded and these recordings archived for future reference. This can be useful for compliance purposes when visitors to a facility need to be recorded for security or other reasons.
