Actually, about smart locks
There are also many puzzling problems.
For example:
Can I still use the smart lock when my finger is injured?
Do smart locks have to use special batteries?
Will the information of the smart lock be lost after replacing the battery?
……
Today, I will share with you the knowledge about smart locks.
Turn into an industry god together.
Can I still use the smart lock when my finger is injured?
At present, in the aspect of fingerprint collection, smart locks include two ways: optical scanning fingerprint collection and semiconductor sensing collection. The semiconductor sensing collection is a capacitance array composed of tens of thousands of capacitors, and the fingerprint head can penetrate the skin surface to collect finer fingerprint details.
Philips smart lock adopts Swedish FPC semiconductor fingerprint sensor, which not only can prevent false fingerprints from unlocking, but also has fingerprint authentication and repair function.
If the finger has only a slight scratch, it can restore some damaged and blurred fingerprint images. When the fingerprint lines are broken, the fingerprint collector can automatically repair the broken fingerprints according to the fingerprint lines without affecting fingerprint recognition.
In addition, it is suggested that you can enter multiple fingerprints for standby when entering fingerprints, so as to avoid that a single fingerprint can not be successfully identified due to serious wear.
Do smart locks have to use special batteries?
A qualified alkaline battery has achieved a high standard in night leakage prevention and voltage stability. As long as the genuine high-quality alkaline battery is selected, the battery is replaced in time when the smart lock is low in power, and the smart lock is not placed in a dark and humid place, there is generally no need to worry about leakage and other safety issues.
However, if it is a frequent business trip or a long-term uninhabited situation at home, you can also choose a special battery for smart locks with double leak-proof technology.
(Tips: Philips smart lock uses the 5th battery.)
Replace the battery, will the information of the smart lock be lost?
After replacing the battery, the information stored in the Philips smart lock will not be lost, and the user does not need to reset the smart lock.
If it is necessary to restore the factory design, open the battery cover or the rear panel cover under the battery box while the smart lock remains open, find the hole position (the letter RES or R is marked above the hole position), and press and hold the hole position for 5 seconds to clear the fingerprint, password and other information stored in the smart lock.
What kind of door can be equipped with intelligent lock?
Most Philips smart locks can be installed on security doors, copper doors or wooden doors with a thickness of 38-120mm, but before installation, it is necessary to provide customer service with relevant parameters such as the type and thickness of the door, the length and width of the guide plate, and to determine the opening direction of the door and whether it has a hook between heaven and earth.
Judgment method of heaven and earth hook:
① Touch the edge of the door by hand to determine whether there is a keyhole.
(2) when the door is in the pop-up state, whether there is a locking tongue pop-up at the top edge of the door.
Do you need to leave a hook when installing the smart lock?
The heaven-earth hook is a lock tongue except the main lock tongue of the lock body. Its working principle is to prevent the door from being pried open by violence by adding lock points, so as to make the door more firm.
However, the hook of heaven and earth resists the risk of violent prying, but it cannot defend against technical unlocking. That is to say, as long as the main bolt is opened, the hook of heaven and earth will be opened as well.
Moreover, due to the increase of the locking tongue, the force on the lock body is multiplied, and the transmission of the whole door lock will have a great burden, and long-term loss will weaken the patience and shorten the life of the door lock.
In addition, many fully automatic smart locks directly drive the locking tongue through the motor inside the lock body. If the hook between heaven and earth is added, not only a more powerful motor is needed, but also more electricity will be consumed. Therefore, if you want to install a smart lock, it is recommended to remove the hook.
This is the end of today’s knowledge.
