Intercom systems are a popular way to take control of access to buildings or restricted areas. A simple to use audio or video system allows you to communicate with persons that are looking to gain access to the building by using an external call unit to call an internal handset. From the handset the occupant, if required can release a secure door allowing the visitor access. Ideal for the use in offices, schools and many other applications. For use for multiple occupancy buildings such as apartment blocks multi-call button systems can be used to gain access to multiple entry points. All our intercom systems are designed to work in conjunction with the buildings access control systems
