1. The battery is above the circuit board
According to the expert, many fingerprint lock batteries on the market are designed above the circuit board, but no matter what kind of battery, it may leak battery fluid after a long period of use. If the battery fluid flows to other parts of the circuit board, it is easy to cause the parts to short circuit, thereby affecting the use of the fingerprint lock; if it is below, it can be avoided. Therefore, when purchasing a fingerprint lock, citizens should check the specific location of the battery.
2. The keyhole is under the panel
Most fingerprint locks can be unlocked with fingerprints and passwords, and are equipped with emergency keys to facilitate unlocking when the fingerprint lock is out of power. At present, many fingerprint locks are designed under the keyhole panel. This phenomenon is very inconvenient for citizens to unlock, and the anti-theft function will be very poor.
This kind of design causes the lock core to be in the front panel. If someone violently removes the front panel, the lock core will be exposed immediately, and others can damage the lock core and open the door. If the keyhole is facing straight, that is, the keyhole position of an ordinary anti-theft door, the lock cylinder is protected by the gate structure.
When buying a fingerprint lock, citizens can check whether the key lock cylinder is facing directly.
3. The drive clutch is placed on the front panel
When the citizen uses the fingerprint lock, after the input and fingerprint or password are correct, a signal will be sent to the driving clutch, and the door will be automatically opened after the driving clutch verifies that the information is correct.
