With its advantages of safety, reliability, convenience and intelligence, intelligent door locks are becoming increasingly popular, and have gradually replaced ordinary anti-theft locks, and the products are introduced at a very fast speed. How should we ordinary consumers choose an ideal smart door lock? Today, Xiaobian will share my experience in choosing smart locks based on the latest T91P smart lock from DESSMANN, a well-known brand of smart locks.
Atmospheric appearance and exquisite workmanship are the first choice.
Modern people pay far more attention to the value of products than before, and at first glance, even the best functions may not arouse the desire to buy. This Deshmann T91P fingerprint lock has a black and square appearance, and the simple and flat lock body looks solemn. The front four sides and four corners of the outer lock body are designed asymmetrically, and with special-shaped handles, it looks unique and innovative. No wonder it won the 2019 German Red Dot Design Award.
The shell of the outer lock body adopts asymmetric design, and the long side of the front side adopts rounded and beautiful large arc chamfering, while the other three sides and two vertical sides of the panel adopt convex-concave combination chamfering, showing an asymmetric beauty. Deschman’s logo is printed on the corner of the lock body, which is more eye-catching. The surface of the lock body shell is oxidized, and after strict salt spray resistance test, the effect of metallic paint is smooth and textured.
T91P lock has intelligent voice prompt function, and the plum blossom hole net on the side is the speaker sound hole. The details of the shell look very delicate. In order to ensure the safety of use, the outer lock body adopts a thickened high-strength zinc alloy shell, the panel strength is as high as 8000N, and the panel weighs nearly nine kilograms, which is super safe and firm.
The upper part of the outer lock body is designed with a sliding cover, which can be lifted and slid open to expose the touch control glass panel-password keyboard+card swiping area, which is used for inputting passwords to unlock, brushing Bluetooth keys and setting functions.
The door lock adopts the ergonomic rotary special-shaped handle, which has a simple and exquisite appearance, rounded edges and comfortable grip. With the design of holding the finger print head, when holding the handle, the thumb can naturally align with the finger print recognition area at the top of the handle shaft. Fingerprint identification adopts FPC sensor, which makes fingerprint identification more accurate. At the same time, the built-in AI intelligent system can predict fingerprint changes and better identify the growth and wear of fingerprints. It is said that the more you use it, the more sensitive it is.
The bottom of the outer lock body is provided with a Mirco USB emergency power jack. In case the battery power is insufficient to unlock, a charging treasure can be inserted to temporarily supply power to the lock body. There is a keyhole in the middle of the bottom. From the complex tooth grooves on the two matching vane keys, it can be judged that the C-class safety lock core with high level is used. Different from others, T91P can unlock the lock independently and directly with the key, without moving the handle.
Anti-pry design of external lock body has been the standard safety measure for all smart locks. The edge of the back of the external lock is equipped with an anti-pick induction switch, which is pressed to start after installation. As long as the lock body leaves the door panel (that is, it is pried by someone), it will trigger the alarm device to ring and send alarm information to the mobile phone.
Matching with the shape of the outer lock, the inner lock body adopts the same asymmetric design, and the workmanship is equally beautiful and exquisite. The inner handle in the middle of the inner lock body is similar in shape to the outer handle. Near the bottom is a conventional anti-lock knob.
There is also a small toggle button near the handle, which has a unique function and is used to lock the handle. Only when it is unlocked can the handle be turned. This is an ingenious design of T91P, which can effectively prevent cat eyes, young children and pets from unlocking, adding a safety insurance.
The battery compartment on the upper part of the inner lock body is designed with four batteries instead of the conventional four-use and four-standby design, which makes people a little surprised. After inquiring, it is known that the official claim that changing the battery can last for a whole year, and it seems that T91P is super power-saving. The button on the upper part of the battery compartment is a Bluetooth switch, which is used to set the lock after Bluetooth is connected to the mobile phone.
At present, almost all lock cores of smart locks are made of stainless steel, which greatly improves the corrosion resistance and prolongs the service life. The stainless steel lock cylinder of T91P reveals a strong mechanical feeling. Although it is usually hidden in the door and not exposed, the workmanship is not sloppy at all, and it is very delicate. The lock core is also equipped with stainless steel door frame edge strips.
Convenient installation and use, rich intelligence is preferred.
The interchangeability between smart locks and common anti-theft locks directly affects the installation difficulty of locks. Lock manufacturers usually choose matching installation accessories in advance according to the size of users’ original locks, so as to reduce the installation difficulty and waste. Before buying, you need to provide data such as the thickness of the door, the length and width of the side strip and the direction of opening the door. In addition to the lock body and lock core, supporting accessories include mechanical keys, batteries and manuals, as well as parts packages with screws and square shafts, etc., but there are many.
Door-to-door installation is entrusted to a local professional lock company, which has become an industry practice. T91P also adopts this installation method, and the official will track the logistics information in real time. When I haven’t received the lock, the installation company will take the initiative to call to make an appointment for the installation time as soon as possible, and at the same time, it will send me a text message to reserve the contact number, which is more worrying.
The old lock I want to replace this time has actually only been used for more than a year. It is a Korean brand smart lock with a fairly high price. Although this lock looks luxurious, it is really not easy to use. First, the fingerprint lock needs to be opened first, which is a bit cumbersome, and it is not easy to touch it in the dark. Second, the transmission mechanism between the front and rear push-pull handle and the internal lock cylinder is complicated, which often leads to the situation that the handle is blocked from issuing cards and automatically locking. Even after being repaired twice, it is still often ill. That’s why I decided to change it this time.
T91P has good versatility, and the installation process is relatively simple and smooth. It only takes more than an hour for the master to complete the installation. After the installation, the K5 looks more beautiful and atmospheric, and the black appearance is in harmony with the brown-red home.
I especially want to show this superfine product here. He is not only skillful in hands and feet, but also very clever. Look at the gadgets he uses and makes himself, and I admire this tool controller. The small rivet gun is several times smaller than the one I use, and the self-made small screwdriver is even more creative. When using it, you can easily adjust the tightness of the door after it is closed by simply pulling the gap in the head to the left and right, without removing the edge or re-drilling.
The installed black T91P smart lock is still in harmony with my dark security door. The appearance is very simple and solemn, which makes people feel strong.
T91P has a variety of unlocking methods, including fingerprint, password, Bluetooth key, traditional key and app. It belongs to one of the most unlocking methods of similar smart locks, and can store 100 fingerprints, 20 sets of passwords and 20 sets of encryption cards, which is enough to fully meet the daily use of ordinary families.
Fingerprint unlocking is the simplest way to unlock smart locks, and it is the most commonly used and popular way to unlock smart locks. The fingerprint identification area of T91P adopts the uncovered design which is integrated with the handle. The fingerprint is unlocked+the handle is pulled to open the door in one go, and the handle is pulled flexibly, smoothly and quickly. The noise of the locking bolt bomb and the recovery action is also relatively slight, and it is not noisy to open the door at night. In addition, it also has the function of preventing the second unlocking. After pressing the handle to open the door once, it will be invalid if you press the handle again, and it will prevent the door from being followed again.
For family members or relatives and friends whose fingerprints are unclear, they can use a password to unlock them. The password adopts a 12-digit virtual password that prevents peeping.
The semi-automatic damping slider is adopted in the lock body. When the password is unlocked, the password keyboard can be exposed by gently pulling up and opening the slider. At the same time, the digital light will automatically light up, which is convenient for you to unlock the password. After the password is unlocked, after pressing the handle, the damping slider will automatically drop slowly without manually closing the slider.
What should I do if my fingerprints are unclear, my eyes and brain are not good, and I can’t use my fingerprints or remember my password? Then it is recommended to use the Bluetooth key, which can be unlocked simply by swiping it in the credit card identification area, which is also quite convenient. Unfortunately, T91P comes standard without a Bluetooth key and needs to be purchased separately. I used Deschmann’s T51 smart lock before, and bought a Bluetooth key, which was just for testing.
As one of the emergency backup means, the traditional key unlocking is designed in the outer bottom lock body. However, as mentioned earlier, T91P’s key is not soft unlocking, but directly rotating unlocking, which solves the trouble that the door cannot be opened in case the battery is dead.
Of course, if you want to fully experience the functions of T91P, you need to install the "Little Butler" APP, which can view all kinds of information of the smart lock, as well as fingerprint input and remote control. I am using three smart locks of Xiaodi brand, which can be controlled together. It is worth mentioning that T91P has intelligent online upgrade function, which can upgrade the system in time according to the official push of Deschman, and benefit from one purchase for life.
The remote control function of T91P is very rich. You can set a group of ten temporary unlocking passwords, and you can also share the Bluetooth unlocking virtual key directly through WeChat and send it to friends who come to visit from afar. After unlocking, it will automatically become invalid, which not only ensures the safety of use, but also avoids the embarrassment of keeping old friends waiting for a long time, which is very user-friendly.
Open the battery compartment cover, and you can connect to the app via Bluetooth to make relevant settings. T91P consumes very little power, and it can be used for one year with four 5th batteries, so it doesn’t need to change batteries frequently, which is equivalent to only two or three cents per day. With the low battery alarm prompt, in case the battery is completely dead, you can use the charging treasure to supply power to the lock through the power socket at the bottom to complete the unlocking operation, or use the traditional key to unlock the lock directly.
Safe, reliable and practical is a must.
Of course, the most important thing about smart door locks is high security, and the more security measures, the better. The physical protection and intelligent safety level of T91P are also quite high. In addition to the above-mentioned shell made of high-strength zinc alloy with strong anti-destruction ability, the highest-level B-class lock core in the current civil smart lock market is adopted, and the 12-bit virtual password function is also adopted. Even if the memory master is watching you, it is difficult to remember your real unlocking password. In addition, it also has the functions of anti-prying, malicious unlocking and anti-hijacking alarm. In case of emergency, it will use app, SMS, WeChat WeChat official account and other channels to automatically send alarm information to you, so that you can check it in time or handle the alarm.
The internal lock is also not relaxed in terms of safety. In addition to the common anti-lock knob, the inner handle is provided with a lock switch, so that the handle cannot be rotated after being pulled upward. Although this is just a small button, it can effectively prevent young children or pets from inadvertently opening the door and running out. In fact, it is more practical to use the button at the top of the handle shaft to unlock, and it can also effectively prevent thieves from unlocking through the cat’s eye.
Not only that, T91P also has some safety protection measures, such as preventing the door from opening again after trailing, one-button protection of APP, automatic alarm when mechanical key is inserted, remote real-time dynamic monitoring of locks, and preventing the small black box from unlocking. It can be said that T91P has done enough homework in safety protection.
Well-known brand, thoughtful after-sales service.
As the first brand of smart locks in China, not only the quality of products is reassuring, but also the after-sales service is an important guarantee for Deshmanzhineng locks to sell well. When you buy T91P at the flagship store in official website, the official will track the logistics information in real time. After you receive the lock, you will contact you to make an appointment for installation at the first time, and you can also consult through the APP at any time during use. In addition, the official provided 2 million yuan of product liability insurance, 3 years of free warranty and lifetime maintenance, 1 year of replacement without repair, 60 days of unreasonable return and free installation, and other after-sales services. Overall, the after-sales service was warm and thoughtful.
