Electronically controlled door locks may have several design solutions:
(a) an electromagnet located inside the door stand and releasing the door lock bolt,
(b) an electromagnet normally located at the top of the door jamb and releasing the door itself,
(c) electromechanical door lock with internal battery, reader and wireless communication with the controller.
Solutions (a, b) require power cables for each door and considerable work with the door stand, which can damage the exterior of the door. Electromechanical locks (c) are a high-class product that provide a high level of security, they don't require wiring and are very energy efficient.
The benefits of these doorlocks are:
- Low operating costs;
- Different types of RFID cards;
- Multifunctional card use;
- Office mode;
- Journal of lock events.
