IPNS have a range of systems for all types of buildings, from single doors to multiple doors and from single call stations to multiple.
Intercom systems can consist of different types of intercoms and sub-systems. The basic system types can be categorised by end user (i.e. commercial, residential, and infrastructure types such as 2-wire or IP). The addition of video alongside an audio element provides a greater level of visual verification with the caller.
Door stations are generally located at key, external entry points and provide a means of requesting access from a building’s operators or tenants following ID verification.
Intercom systems require will integration with the door or barrier they control. This will involve a relay trigger to open an electric door lock or to raise a barrier to allow vehicles access to loading areas.
All door stations communicate with either one or multiple handsets in a either commercial environment, or in an apartment in a multi-tenanted dwelling, depending on the system topology.
IP solutions tend to reside on a dedicated network but can be integrated or interfaced with existing network infrastructures to provide site wide operation, allowing unmanned buildings to be managed off site.
Many intercoms can be integrated in to other security systems also. By using relay interfaces, it is possible to trigger CCTV cameras and activate video recordings or they can be interfaced with a card or fob access control system.
