Elementary Knowledge of Smart Locks

1. The difference between smart locks and ordinary locks.

The core part of the ordinary lock is the mechanical lock cylinder, which can only be opened by key. The smart lock adds the concept of authentication, such as fingerprint identification, RF keys, IC cards and Bluetooth modules through the electric actuator.

In addition, the smart lock also supports the Internet of Things, but not all products have this feature. Generally speaking, the innovation of smart locks is reflected in the upgrade of the user experience: they are safer, smarter and more convenient.

2. The more expensive the smart lock, the better. Is it true?

The intelligent lock is as an intelligent hardware, its costs are directly proportional to the selling price. Therefore, the higher the price, the more advanced the parts, the better the workmanship and the higher the manufacturing cost. And some low-end products also have many functions, but the commonly used parts (e.g. fingerprint modules) are inferior, and the process and design of the low-end product are also not better than that of the high-end one.

3. What if the fingerprint recognition speed is slow?

Whether it is an optical fingerprint module or a semiconductor fingerprint module, if the fingerprint recognition speed is slow or the false rejection rate is high after the smart lock is used for a period of time, it may be caused by the dirty cover plate. Cotton balls can be dipped in alcohol to wipe the plate. If the speed is still slow, it is recommended to contact the after-sales service personnel for maintenance.

4. What if the smart lock battery is dead?

If the smart lock is out of power, it can be charged and opened by a power bank. (The smart lock has a USB interface.)

5. Can children use smart locks?

Generally, children before the age of four are in a rapid development period, and their fingerprints have not yet been set, so fingerprints entered into smart locks are only for temporary use. After the age of four, fingerprints can be used for life if they are set.

6. Can an injured finger be recognized by the smart lock?

At present, many fingerprint modules of smart locks use AGC (Automatic Gain Control) circuits when they are recognizing the fingerprint, which supports a certain fault tolerance. If the finger is slightly scratched, fingerprint recognition will not be affected. If the finger is severely scratched, the fingerprint recognition function cannot be used.
