As we all know, the common anti-theft door lock is composed of two sets of mechanical structures, one is the lock opened with a key from the outside, and the other is the lock triggered with an anti lock button from the inside. The former is the target of technical unlocking. Depending on the level of the lock cylinder, there will be different opening probability, and even some locks will be easily opened. The latter is mostly controlled by people in the room. As long as it is locked from the inside, even if it is opened from the outside, the locking device will become the second line of defense to protect the safety in the room. Based on this principle, Snail Housekeeper Smart Door Latch (hereinafter referred to as Smart Door Latch) has made great efforts on the anti lock device, trying to create a technical lock buster. What is its use experience? Can technical unlocking be effectively prevented?

    [Appearance & Structure] The size of this smart latch is larger than Xiaobian imagined. When I got the packing box, I was a little worried about whether it would take up a lot of space, but after installation, I found it was pretty good.

    The conspicuous words on the package box read: 100% The anti lock technology seems to be full of confidence.

    After opening the package, I found that it was not small, its size was similar to that of the old style big brother, and it was very heavy.

    Stand up straight and make a face. There is a round button on the top of the front. It is large in area and surrounded by a circle of indicator lights. It looks very comfortable and has a good design.

    One orange square button on the left and one orange square button on the left, and press on both sides at the same time to remove the latch from the door.

    The back is mainly composed of three parts: the upper adapter is installed on the door locking button to control the locking button; The middle is the battery compartment, which holds four section five No. dry cell; Below is the balance base, which is used to adjust the installation posture of the latch.

    The shape of the fitting button is a curved strip, which is compatible with common anti locking buttons.

    It can be removed by itself, but the official said that the fitting button has only one shape, so it didn't have to be replaced, which is a pity.

    The middle battery compartment can be installed four section five No. 2 battery, which can guarantee half a year's endurance three Annual standby; There is a fluctuation switch in the middle of the battery compartment to adjust the rotation direction of the latch to adapt to the door locks in different directions.

    Adjust the height of the balance base by rotating the knob at the bottom.

     Maximum height:

    [Accessories attached] Smart latch is attached four section five No. 1 dry cell and one 3M Base.

    The battery installation is smooth, but the battery in the left battery compartment is difficult to pull out.

    3M The adhesive base is used to fix the smart latch to the door. Because it is fixed by adhesive, it is difficult to use it again. It seems better if it is fixed by magnetic suction. Moreover, there is no additional adhesive sticker at random. If you want to put the latch on another door, you can't do it.

    Installation The installation of the smart latch is very simple, requiring only three steps:

    Step 1: hold 3M Paste the adhesive tape onto the anti lock button in the following posture.

    Step 2: Insert the two vertical holes next to the smart door latch fitting buckle correspondingly 3M Glue the base insert.

    Step 3: Adjust the balance base to keep the smart door latch upright (the balance base has its own strong magnet to firmly hold the anti-theft door).

    The smart latch is firmly installed on the door, hardly shakes, and the size is also suitable. It does not occupy as much space as expected.

    [Use and feel] The principle of the smart door latch has been mentioned before. It is mainly to control the switch of the anti lock button to achieve the anti-theft function. As long as the door is locked from the inside, even if the thief opens the door lock outside, it will not help.

    The switch to control the anti lock button provides three ways: one is controlled by the button on the latch, the other is controlled by the mobile phone APP One is controlled by a snail key. Multiple ways of unlocking are provided to prevent users from accidents, such as when the phone is out of power or the button is broken.

    The switch of the latch is accompanied by the sound prompt and the indicator light flashing. The blue flashing indicates that it is closed, and the green flashing indicates that it is open (the following figure shows the closed and open status respectively).

    The bolt rotates with moderate force and even speed, accompanied by the "Zizi" gear sound, which is full of mechanical feeling.

    However, after pulling the direction control switch in the battery compartment, Xiao Bian found that the rotation direction did not change. After pulling off the battery, he pulled the switch and then installed the battery to solve the problem.

    The latch controls the anti lock button by turning the adapter button, and the door latch is opened when the "open" button is received / The "close door" command starts, about 3S Middle left and right open / When the door lock is closed, the response time is slightly slow, because if the door latch is manually controlled, only one It could be done in seconds.

    mobile phone APP It is the second way to control the anti lock button. APP The design of is relatively simple, and the binding only needs to open Bluetooth, close the phone to the latch, and follow the APP Prompt operation is enough, convenient and fast.

    But mobile phones APP On / Lock failure occurs, which is very dangerous. If the phone APP If it fails and the user is outside the door, there is only one way to open the door: snail key. And every time you quit APP Opening it again will reconnect the latch, which is very troublesome.

    The smart door latch provides the automatic door locking function, which will automatically lock the door after leaving for a certain time to ensure safety. This design is very considerate. however APP There are orange dots in front of the "Open Automatic Lock" and "Close Automatic Lock" buttons on the interactive interface of the, and there is no corresponding indication background color, so the APP It can't be seen at a glance whether the "Auto Lock" function is turned on at present. I hope it can be improved in later versions.

    [Summary] One sentence summary: The design concept of Snail Housekeeper · Smart Door Latch is simple, but practical. The security lifeline of the security door can be controlled by controlling the anti lock knob, which can not only control the switch manually, but also control the mobile phone APP It can also be controlled through the snail key (the snail key is not involved in this experience). Unfortunately, it cannot be controlled remotely at present. Although it is a small pity, it also directly avoids the security risk of the latch accessing the Internet.

    Imagine that if we take out the mobile phone or snail key after going out, and lock the anti-theft door through the smart latch, no matter how good the thief is, there is nothing he can do. When we sleep at night, we can press the button gently and lock the latch, so that we can sleep safely all night long. This lifestyle is actually very comfortable.

    But there are also some small shortcomings of the smart door latch, such as the need for installation and use 3M The adhesive base is fixed, so there are some shortcomings in the convenience of use. It would be better to support cleaner fixing methods such as magnetic suction; APP The design is relatively simple, and failure occurs, and further optimization is needed to“ 100% Prevent technology from unlocking ".
