Autonomous access control systems are necessary when in a simple way we want to give security to an entrance door.
The advantage of access control is that we will not have to give an entry key to each tenant, simply with a unique entry code they will be able to open the entrance door,
There are also models of autonomous controls that can give a different code to each tenant, thereby increasing the level of security.
Models of autonomous access control that work with cards, and depending on the model and to increase the level of security, the card plus a code is needed.
Other access control models that use different technologies to operate the door strike such as:
Proximity cards, numeric keypad, Bluetooth, remote controls.
