An electronic lock is an electromechanical system that allows the opening or closing of a door through the use of current. Its degree of security will depend on the closure system chosen and its opening method.
Technological advances have reached this area with encrypted coding systems such as the AES/128 of the American ASN, which increase their security.
Main types of electronic lock
As for their types, the most common are electromagnetic, which have magnets and coils, and thanks to having a mechanical safety system that can be opened more easily in case of emergency. When installing them, the door frame must have a device with an electromagnet, and a metal foil must be placed on the other side so that the current flows through the magnet and, upon receiving electricity, the door is opened.
Reversible models can be used in armored and sheet metal doors, both interior and exterior, and those with an electric bolt with intern are more suitable for wood and metal doors. Some locks have a monitor, magnetic switch, door closing system, and even an alarm that activates when the input to which it is connected is not completely secured, as an extra security element. The electric latch are used primarily for internal access and can operate with direct or alternating current. The two basic configurations of an electronic lock are:
Standard: the lock is locked until the coil is activated by electric current. That is, the electric lock remains closed.
What is an access control system?
Being the Electronic Door Lock an essential element in an access control system, by itself, it does not perform this control except in some of its models and always for a limited level both in time and in the people to whom those few models allow to have of a numerical code.
This is due to the fact that the function of a lock evolves in the electric ones, achieving greater security and offering the comfort of being able to handle them from a distance, but its objective is not the professional access control but to avoid the trouble of losing a physical key when it can be opened through codes, proximity cards, electronic keys, biometric systems, remote control or mobile application.
The electronic lock is an essential functional part of access controls, which are the devices that give the order to open doors because they are connected to it. Only an electric lock can receive the impulse transmitted by the access control to open remotely to authorized persons or vehicles. But access control is the entire system that, in an automated way, allows to effectively approve or deny the passage of people or vehicles to restricted areas based on the security parameters established by a company, commerce, institution, or any other entity.
Fingerprint Access Control Systems also make it possible to keep an automated record of the movements of an individual or group within a given space.
