Depending on the requirements of the installation, the use of an autonomous or centralized access control system is recommended. In both configurations, they can be integrated into a porter or video entry system.
The autonomous systems control a door/an access and are indicated when a simple access control is required, without recording of incidents and to complement the electronic porter or video doorman that allows the access to the building to the neighbors, for example: Office, small offices, garages.
The centralized systems allow to solve complex installations of multitude of accesses and with advanced functions.
There are several technologies depending on the type of interaction between the identifier and the reader that allows or denies access to the restricted zone.
