Door Entry Systems are intercoms which allow private dialogue (e.g. door phones) or announcements (e.g. public address systems).

They can either be mobile (i.e. like walkie talkies), or permanently secured in locations like buildings or vehicles.

Fixed intercoms installed in buildings tend to comprise of microphones and speakers which are connected to a control panel either by wires, or wirelessly.

Intercoms can also be hooked into other systems to control other devices e.g. door latches ,gates, etc. This makes them ideal for access control on door and gate automation.

Another option is they can be either audio or video based, the choice of which depends on the application and your budget.
