You can open the lock using a magnetic card or key fob. To cope with this task, identification of the key code is required. Each card or key fob has its own code, it is indicated on the controller when installing the electronic device.
The code is a unique set of characters and will not be changed later. When the lock is opened, the information is read a code with an identifier, this requires direct contact with the reader or a chip or card is used that are in the same electromagnetic field with the reader.
Then the identifier is activated and the code signal is transmitted to the device. The fact that information has been received will be indicated by a sound signal or a short-term light indication. Then the code is transmitted to the controller.
In some cases, a more complex controller device is relevant; for this, software control is used. This program has numerous advantages, for example, it records the time of entry and exit of specific citizens, keeps a log of visits and other events.
To open the Digital Door Locks from the inside of the room, if there is no need to fix the time of entry and exit, use a button equipped with the function of ignoring the reader.
The controller is given a signal indicating a manual reader, and it allows the entrance, as a result, the electronic lock opens.
You can open the lock by entering a code on a special panel. This device is relevant for rooms with high traffic, usually at the driveway.
In some types of devices of a more modern type, innovative technologies are used, for example, to prevent a numerical combination from being calculated, the models suggest an additional two random digits to be entered on the monitor. To open the lock from the inside, a special button is used.
You can open the Fingerprint Door Lock using biometric data. In this case, the mechanism is unlocked after the device has adopted certain physiological parameters of a person.
Most often, a fingerprint is used. And this has certain advantages, because keys and cards can be lost, and biological data always remain with a person and are unique.
The user presents the data that the controller receives, then the information is converted into a digital signal, the device compares it with the code stored in the memory, and if there is a match, the door opens.
To control the mechanism of the electronic lock, a certain voltage is required, it is generated by the power source. The electronic lock can be supplemented with a video on-door speakerphone with a door station.
