To put it bluntly, I was born with "key forgetting syndrome".

365 days a year, there are always a few days when I have to trouble the company to open the lock. In order to overcome the problem of forgetting the key, I tried various methods, such as sticking a small note behind the door, silently reading the key when going out, putting a spare key in the office, etc., but most of the time I can only remedy after the fact. I just came back from work and ran back to the company to get the key Occasionally I leave my spare key at home. I love and hate keys. When I was tortured by keys and was about to collapse, Lei Feng sent me a smart lock beeper T750, which directly opened the lock with fingerprints. It instantly refreshed the three perspectives. There were locks that were so easy to use. Maybe I don't need to worry about forgetting my keys anymore. I just want to say that Lei Feng is a real Lei Feng, Maybe only Lei Feng can give me such a good gift.

In fact, fingerprint unlocking is only one of the functions of this little tick T750. It also supports key password unlocking, Bluetooth key unlocking, mobile phone unlocking, remote authorized visitor unlocking and other unlocking methods. I am really dazzled by so many unlocking methods. It is no problem to say that the time of seven days a week is different every day. Fingerprint unlocking is the most convenient one for personal use.

In view of the problems such as the high degree of fingerprint wear of the elderly and the change of the children's fingerprints, this smart lock also has three physical keys+one Bluetooth key as a backup, that is, press to open, and I give each parent one on his or her body for emergencies.

Unpacking

In terms of packaging materials, Xiaodi T750 adopts multi-layer protection, which is in place. The outer layer is corrugated paper packaging, the middle is color printing packaging box, and the inner layer is buffer foam, which can effectively protect the safety of the product and avoid product damage caused by bumps during transportation. The color box design is simple and beautifully printed. The orange mini product logo is more eye-catching, and the upper part has a portable handle, which obviously took a lot of thought in design.

Open the packaging box, there are quite a lot of products and accessories inside, with a two-layer layout structure. The upper layer is the lock cylinder, accessories and instructions, and the lower layer is the lock body and internal and external handles. The two layers are fixed by the buffer foam slot, and the protection is in place.

At the top is a welcome opening: worthy of the first lock of your new home! The interface is friendly, the printing is exquisite, and it gives me a warm feeling. On the back, there are some precautions for the use of the product, fingerprint entry, phone unlocking and other information.

There are many kinds of accessories, including hardware, keys, batteries, installation dimension engineering drawings, door edging, hand body, remote keys, instructions, etc.

Door edge strip, made of stainless steel.

Hardware * 1 package.

Bluetooth key * 1.

Physical key * 3.

No. 5 battery * 4. There is an English trademark of DESSMANN on it. Unexpectedly, Deshmann can make batteries by himself.

From the perspective of the types of accessories, the feasibility of self installation of the mini T750 is not very good. Fortunately, the official provides special personnel for free on-site installation. However, the size of the door and relevant data should be provided in advance, so that the subsequent installation will be fast and efficient. About half an hour before and after the installation of my own lock, the work will be completed, as will be described below.

appearance

In terms of appearance, Xiaodi T750 is rich in color matching. It can choose Tuhao gold and Moonlight silver. It is made of zinc alloy, which has the characteristics of high strength, corrosion resistance and light weight. The surface metal is sandblasted, which has a fine feel and is not easy to leave fingerprints. The surface is covered with metal luster under the afterglow. The picture shows Moonlight Silver color scheme.

Structurally, the mini T750 adopts a split design, including the outside handle and the inside handle.

Door outside handle

As the name implies, the outside handle is installed outside the door. Both sides of the whole panel are treated with beveled arc surface, which has a strong three-dimensional sense. The physical handle has round corners, which is comfortable and thick to hold. The functional components include physical slide cover, password key, fingerprint sensor, physical handle and lock body status indicator light. This indicator light is ingeniously integrated with the lock body's LOGO "DI". When activated, it will light up the light blue background light, which looks more scientific at night.

The physical slide cover slides up and down along the guide rail at the edge. It has no problem with the feel and seam. I don't know whether it will be scratched or discolored after a long time. The slide cover plays a role in protecting the digital password keys and fingerprint sensors. Compared with some exposed password keys, it is more secure, and it also makes the style of the whole lock more unified.

This little Dike T750 is jointly produced by Suning E-shop and Deshman. It is a new product based on the combination of Suning members' big data demand mining and Deshman's intelligent product research. It is also Deshman's first C2B reverse customization extreme product. It is understood that the crowdfunding price is as low as 1599 yuan.

The sliding cover surface is inlaid with a protruding decorative strip, which avoids the monotony of the sliding cover and plays a better role in embellishment. At the same time, it was found in use that pressing this decorative strip upward to slide the sliding cover is very convenient and carefully designed.

Open the slide cover, you can see the fingerprint sensor and the digital password button on the upper part, and the product logo "DI" with a small tick is designed in the middle. As in the era of smart phones, seeing the traditional physical keys has a sense of familiarity, which is more tactile than the popular touch screen, and more secure without leaving fingerprints. At the same time, the elderly and children at home are more convenient to use digital buttons because their fingerprints are incomplete.

The bottom is designed with a physical keyhole and a MiroUSB interface, which is relatively hidden, and has a direct relationship with the importance of these two interface holes. If thieves want to damage it, this location is not easy to start. Besides, the T750 has a built-in super strong C-level lock cylinder, which also increases the difficulty for thieves. The MiroUSB interface is generally not used. Only when the lock body is out of power and the key is not available, the power bank can temporarily power up through this interface to unlock.

The back is designed with various holes for mechanical linkage with the lock cylinder. In addition, there are two data lines, one is a 4pin data line for digital physical keys, and the other is a 10pin data line for fingerprint sensors. The outside of the wire is protected by nylon braiding, which is waterproof and abrasion resistant.

Interior door handle

In terms of appearance and material, the interior door handle is basically the same as the exterior door handle, and the appearance is more square and neat. The function module of interior door handle includes battery compartment, central control circuit board, Bluetooth setting switch, interior lock switch and physical handle. The power supply and control parts are in the door, so the safety can be greatly guaranteed.

The battery compartment adopts a snap ring structure, which can be opened only by slightly pressing the snap ring. It is equipped with 8 slots for No. 5 batteries. In fact, 4 batteries can be used for normal power supply and operation, and the additional 4 slots can be used for standby batteries, with a lifetime of up to 1.5 years. The battery compartment cover is marked with the installation instructions of the battery and the two-dimensional code of the lock. Scanning can download the exclusive APP of Xiaodi to bind and set relevant unlocking information.

A physical key switch is also hidden at the bottom of the interior door handle, which is mainly used to start the pairing mode of the lock body, synchronize information with the mobile phone APP, and enter this mode for subsequent fingerprint recording, changing the unlock password and other operations.

Lock cylinder

The lock cylinder is the key to measure whether the performance of a lock is good or bad, and whether it is safe or not. In terms of security, the Didi T750 uses the highest security level C-level lock cylinder. The anti-theft design can be called the safe level. Thieves can only flinch when they see this lock. It supports anti pry alarm, trial opening alarm, hijacking alarm, door opening information monitoring, remote video monitoring, remote real-time call and other functions to ensure family safety in all aspects. 　　

Xiaodi T750 lock cylinder is designed with a two-way lock tongue and three anti-theft self elastic lock bodies. This design can automatically pop up the anti-theft lock body to lock when you close the door. For users living in cities, they will never worry about the embarrassment of forgetting to lock the door when they hurry from 9 to 5.

The shell of the lock cylinder is made of metal. The black paint looks reliable. It is very thick when held in the hand. There are two openings on it for the mechanical linkage of unlocking through the front and rear door heads.

The only data cable on the lock cylinder is used for the central control circuit board. When Bluetooth unlocks or remote unlocks, the unlock command can be sent to the lock cylinder.

In addition, the little tick T750 is also equipped with a Bluetooth key, which is very sharp. If there are elderly people at home who are not able to use the smart lock, they can use this Bluetooth key to unlock, which is very convenient. The staff of Deshman introduced on the spot that, compared with the traditional door lock that finds the key, takes out the key, finds the key hole, and sometimes scores both sides, the T750 fingerprint lock can save users an average of 7 seconds every time the lock is opened. According to the calculation of opening the door three times a day, the cumulative use of 50 years, the final answer is an amazing 106 hours. 　

install

After the order is placed by the little tick T750, the estimated delivery time can be booked and installed by JD and Tmall with the Deshman customer service. The master usually calls in advance to confirm the appropriate installation time. The service is relatively considerate. Before installation, the standard door size and relevant data required by the manufacturer shall be provided. Installation is much simpler, and no additional cutting or slotting is required for the door. My door is relatively standard. The installation master looked at it and said it was very good. It can be installed directly, so it started.

The first step is to install the lock cylinder. There is nothing to say. Before fixing the screws, pay attention to whether the upper and lower heaven and earth hooks are fastened firmly.

The second step is to install the outside handle. Pay attention to the anti prying switch. If the door structure is uneven, you can add a gasket to pad it up. Otherwise, the beeper will not alarm you when thieves pry the lock.

Anti prying switch, add a gasket.

Step 3 Install the interior door handle, and pay attention to the connection between the main control panel, battery pack and the exterior door handle.

Test, manual. It's only half an hour.

People rely on their clothes and horses rely on their saddles. After installing the mini T750, Mashan feels a lot taller.

experience

The intelligent function of Xiaodi needs to connect to the mobile phone APP for setting, and synchronize to the lock body through Bluetooth, such as fingerprint entry, unlocking password storage, connection to WIFI, etc. The built-in register of Xiaodi central control can store 80 sets of fingerprints, which is not enough for ordinary families, but also more than enough for small companies.

First, scan the QR code of the battery compartment cover, download the app, and then register and log in.

After everything is done, the first thing is to enter fingerprints. Families need to enter fingerprints at one time. The little tick T750 supports 80 fingerprint entries and 150 users, so you can enter more fingers, then press the key to unlock the password, pair the Bluetooth key, etc. In the above steps, the lock body Bluetooth synchronization switch needs to be activated. The above setting information can be synchronized to the small tick T750 by long pressing the switch of the door handle.

The Bluetooth unlocking method of mobile phone is very convenient. You can unlock the phone through the phone password, shake, gesture, click, graphic password and other methods. However, if there is a fingerprint, this can only be used when the finger is injured or in other situations.

To add a Bluetooth key, you also need to start the Bluetooth synchronization switch of the lock body. First, long press the button of the Bluetooth key. When the indicator light starts flashing, synchronize the information of the Bluetooth key to the lock body according to the APP prompt, and then complete the binding of the Bluetooth key and the door lock. It is also very convenient to use the Bluetooth key to open the door. Close to the door lock, press the switch of the Bluetooth key. It is especially suitable for the elderly, but it needs to be very careful, because once the Bluetooth key is lost, others can also open the door at the same press.

If relatives and friends come to the house as guests, and you haven't arrived home yet because of overtime work, you can't let friends wait at the door of the house. You can send a temporary unlocking password to a friend's mobile phone through SMS unlocking, and the friend can enter the house by himself, which is very convenient. The problem is, how to prevent others from peeping into the password? Xiaodi T750 supports disordered digital input of passwords. As long as correct passwords are input continuously in the middle, the security is guaranteed.

Then there is the query of unlocking records. If you work overtime in the company and your child finishes school, do you walk home halfway? Or whether grandparents go out on time to pick up and drop off their children. You can check the unlocking records in the App to find out the specific unlocking records at what time and how. The alarm setting can also be activated. In extreme cases, if a thief is holding or betraying the lock, a specific finger fingerprint can be entered in advance. Once the finger is unlocked, the small drop T750 can send an alarm synchronously for timely remedy.

Although there are so many unlocking methods and intelligent functions of Xiaodi T750 listed above, I mostly use fingerprint unlocking, which is very easy to use and highly recognizable, and can be successfully unlocked almost once.

Bluetooth remote key unlocking

In order to test the identification ability of the fingerprint sensor, I can touch the dust on the windowsill with my fingers, and then unlock the window. I failed to identify it once. It is recommended that the fingerprint sensor be kept clean when unlocking. After all, the fingerprint sensor is an optical scanning and identification device, and more flying dust will block the infrared light line, It is supposed that the sliding cover outside the T750 is designed for this reason.

summary

For this Xiaodi T750 cloud intelligent housekeeper, the stability of fingerprint unlocking is the first thing to be affirmed, and it is also the most frequently used unlocking method for me. It has high recognition ability, fast response speed, and is very easy to use. It seems that the experience of forgetting to take the key and being rejected is something of the last century. The C-level lock cylinder, rich cloud functions and zinc alloy lock body of the Didi T750 also bring strong visual impact on the premise of ensuring safety. It adds a lot of color to the Didi T750. In general, it is a very good cloud smart lock and worth recommending to friends. Just within half an hour of the installation of Xiaodi T750, neighbors could not help being curious and came to inquire about the manufacturer and model of Xiaodi. I believe that in the near future, Xiaodi's smart door locks will gradually become popular in the community.

If you can't say enough, after half a month of actual use, I personally felt that the opening and closing of the small Tipper T750 was a bit loud, and it would be better if it could be quieter. Then there was the sliding cover of the outer door handle. After the fingerprint was unlocked after work, I forgot to cover it several times. I wonder if the manufacturer has any good methods.
