Unlocked doors may offer practicality, but they lack the essential element of security. On the other hand, traditional keys and locks, while secure, often compromise on practicality. Exterior doors equipped with fingerprint lock systems strike the perfect balance between security and usability. Leveraging this state-of-the-art technology, fingerprints excel in identity recognition due to their uniqueness, remaining constant throughout a person's life. Unlike traditional keys prone to loss or misplacement, fingerprints serve as keys that can never be lost or misplaced. If fingerprint locks can unlock your smartphone, why not integrate them into your home?
One of the most mature fingerprint scanning methods, optical sensors operate similarly to smartphone cameras. They create a fingerprint image while algorithms identify unique ridge and skin patterns. However, their effectiveness relies on sensitivity to capture every detail of the finger. These sensors also require adequate light sources for capturing high-quality fingerprint images.
Integrated into locking systems for higher security, capacitive fingerprint recognition relies on capacitors as their primary components. When a finger touches the surface, the capacitor stores a small amount of electric current. As there is no contact between the fingerprint ridges, no data is generated. These voltage fluctuations are recorded digitally, allowing for comparison. Capacitive sensors can remember multiple fingerprints and enhance image recognition capabilities.
Modern fingerprint scanning technology utilizes ultrasonic sensors, composed of transmitters and receivers. Ultrasonic signals are either absorbed or bounce back off the ridges of the fingerprint. Pressure-sensitive sensors receive the reflected signals, creating a 3D fingerprint model. Although not the fastest recognition method, this technology is highly reliable.
As fingerprint recognition occurs, the magnetic lock activates, generating or interrupting the magnetic flux to lock or unlock the door. Magnetic locks are exceptionally secure, capable of producing a powerful electromagnetic field with forces ranging from 250 kg to 1000 kg, firmly securing the door in place. The design of doors with magnetic locks ensures that, even during a power outage, the locking state is maintained, allowing occupants to exit the building in case of an emergency.
Once you place your finger on the reader for the first time, the fingerprint image is recorded. Repeat this process whenever you want to grant someone access to your home or apartment. If the fingerprint is recognized by the door lock system, the door opens; otherwise, unauthorized individuals are denied entry. To prevent misuse, some readers also measure heart rate and body temperature, enhancing their reliability.
In rare cases where the reader does not immediately recognize your fingerprint, consider the following tips:
Press your finger on the reader for a slightly longer duration.
If you've applied hand cream, wipe and dry your hands.
Injuries to the finger may hinder fingerprint recognition, so record fingerprints from multiple fingers for redundancy.
In conclusion, the Exterior Fingerprint Door Lock represents the epitome of security and usability, seamlessly integrating into the modern smart home landscape. For door lock dealers, real estate developers, and technology companies, understanding the working principles and usage methods of these locks is paramount in delivering cutting-edge security solutions to their clientele.
