[Foreword: A smart family cannot live without a good lock]
In the 1990s, a building named "House of the Future" became popular in major news programs and scientific magazines. Covering an area of 6,600 square meters, it is surrounded by mountains and rivers, and its appearance imitates the aristocratic manor in the 18th century. However, as the name suggests, its interior is full of modern automatic devices and computer control systems. For example, it can automatically turn on the air conditioner and automatically drain the bathtub when the owner is about to get home; Can automatically remember guests’ preferences for temperature and TV programs when they visit; The bathroom has a complete automatic physical examination system, and even the trees in the yard are monitored and maintained by computers in real time.
Of course, for today’s friends, the "House of the Future" and the system enjoyed by its owner, Bill Gates, are no longer so lofty. If nothing else, the "whole house intelligence" experience, which cost more than one billion dollars 30 years ago, has long been standard in many families.
As big as intelligent TV, refrigerator and air conditioner, as small as a toothbrush, a mirror and a lamp … When the tide of Internet of Things and AI swept the whole intelligent manufacturing industry, when the price of AIoT equipment dropped again, for many families, on the one hand, we enjoyed the comfort of daily life that we had never had before, but on the other hand, we began to encounter some new problems.
For example, for some old houses, indoor smart appliances can be easily deployed, but the old doors and windows have become incompatible with the intelligent system of the whole house in terms of "use experience", which is extremely awkward. For another example, because a large number of modern household products have the ability of edge computing and user information perception collection, this means that in the event of burglary, the loss will not only be temporary financial, but also important personal privacy data.
Because of this, for modern digital families, it is actually necessary to equip a door lock that is safe enough and smart enough. Just some time ago, our Sanyi Life also changed into Samsung’s latest DR719 IoT smart lock. We also take this opportunity to show you what kind of quality a high-end smart door lock product should have and what kind of home security experience it will bring.
[Appearance: Push-pull style is not only beautiful, but also has more practical significance]
Looking at the smart door lock products on the market at present, there are basically two schools in appearance design. First, the shape is closer to the traditional door lock, and the "down-pressing type" of opening the door by rotating the door handle is adopted; The other is relatively novel in shape, and the unlocking method is similar to the "push-pull" type of automobile doors.
So, what kind of scheme does Samsung DR179 adopt? I have to say that its design this time is actually quite confusing. When you think that the square door handle is a rotary switch, you just need to get close when you reach out to open the door, and the door lock will automatically open with a click, which makes people discover that DR719 is actually a push-pull smart door lock.
From another angle, we can clearly see the push-pull arm at the door handle. In fact, Samsung may be the earliest and most active brand to promote push-pull door locks among the mainstream smart door lock brands. As early as 2012, they have changed the design of their smart door locks from the push-down door handle to the push-pull switch.
So, what are the benefits of push-pull design? Imagine that when you approach the door with a heavy object in your arms, the push-down doorknob means that you must first find a way to free your hand and operate the door lock with greater strength. But the push-pull switch can solve the problem only by lightly touching the switch at any position of the body, especially for the elderly, the push-pull door lock will be much easier to use than the push-down one.
In addition, from the perspective of durability, because the handle of the push-down door handle is very long and far away from the rotation fulcrum, it is possible that the door handle will sag after long-term use, which greatly affects the impression. The push-pull door lock, because of its short arm and light handle, can avoid deformation after long-term use, adding another point to its appearance.
[Software analysis: In addition to the Internet of Things, there are humanized details]
Some friends may have noticed that the product category of Samsung DR719 is called "Internet of Things Smart Lock", whether in the relevant official pages or in our experience evaluation. Smart locks are naturally as the name suggests, but what exactly does the Internet of Things mean?
The answer to this question can be found in the APP of DR719. First of all, as you can see, although this is Samsung’s latest flagship global model, our version of the Bank of China still has additional adaptations for the domestic smart home environment. For example, it can be linked with smart speakers of some well-known domestic brands, and even support smart doorbells of third parties.
In addition, as you can see, DR719 can support remote real-time monitoring of the working condition of door locks and the time of people entering and leaving. Please note that when we intercepted this picture, we were not in the area where this door lock was installed. This is because DR719 is a smart door lock with built-in WiFi module, which is different from those products on the market that rely on Bluetooth to connect with the mobile phone in short distance. DR719 can connect to the wireless network at home without additional gateway terminals, thus realizing the real remote monitoring of the door lock status.
Not only that, thanks to the "true Internet of Things" attribute of DR719, Samsung even equipped it with quite creative and practical functions of regular visitor password and temporary visitor password. Both of them can specify that the door can be opened successfully only in a specific time period, and the invitee is not required to be present when setting, and the authorization information can be directly set and sent remotely, which will take effect immediately on the remote smart door lock. Imagine, if you are away on business for a long time, and you need to manage the access to the office at any time and grant the new colleagues the right to open the door, then it is obviously more convenient to use this function.
[Feeling and summary: it is a top flagship product]
Finally, let’s talk about the feeling of using the lock DR719 during this time. The first thing to say is that, as the top flagship model of the entire product line of Samsung Smart Lock, the biggest change of DR719 compared with its own brother products is that it has more authentication methods.
For example, you can directly use the semiconductor fingerprint sensor on the door panel for authentication, and you can enter the door password through the touch password panel. It is worth mentioning that this password panel of Samsung DR719 is inductive. As long as someone stands in front of the door, the password panel will light up directly, which will itself play a deterrent role for people with malicious intentions. Even if someone lingers in front of the door for a long time without any operation, the door lock will give out an extra warning sound, which can be said to be very intelligent.
In addition to fingerprints, DR719 also supports functions such as key card contact opening, emergency entity key opening, and mobile APP opening, especially the proximity sensing of key cards, which is sometimes more natural and more "advanced" than fingerprints.
Secondly, DR719 is more thoughtful than similar products in some details of security settings. For example, under the cover of its inner door, there are two very interesting small switches hidden. One is to adjust the volume of unlocking and prompting sound effects. If someone often comes home late at home, you can turn down the volume or even mute it completely to avoid disturbing your neighbors. The other is to switch between automatic and manual locking mode. Although DR719 supports automatic locking after closing the door, considering that most users may have the habit of manually locking, it can further save power after switching to manual.
In addition, as the most representative international first-line smart door lock at present, DR719 also has some humanized functions that domestic brands have not considered. For example, its fuselage has a built-in fire sensor. Once it detects that the indoor temperature is too high (suspected fire), it will automatically remove all the protection, turn on all the LED lights on the door lock and automatically unlock the door, so that users can escape with the fastest speed. To be honest, although many of us may never encounter a fire in our home, once something really happens, such a small function may be very useful.
On the other hand, for products such as "smart door locks", because the function is relatively simple after all, throughout the current market, most products are basically similar in appearance and technical characteristics. Like a high-security lock cylinder and intelligent control with an APP, it has long been a trait that even entry-level products with a price of several hundred yuan will have. Because of this, what kind of smart lock is a "good lock" for consumers, and what are the advantages of those high-end products on the market? In fact, many people do not have a clear concept.
For our Sanyi life, before switching to Samsung DR719, we actually bought and used some other smart door lock products. As the saying goes, "no comparison, no harm", perhaps it is because of such a rare "lock change" experience that we can actually feel the real value of a flagship product like DR719.
Yes, you can say that everyone is a lock anyway, and now similar products basically have fingerprints and some intelligent functions. However, it has to be admitted that not all smart locks can be connected to WiFi, not all smart locks can actually set the remote key through the APP without the presence of the user and the licensee, and not all smart locks have such a labor-saving opening experience, with many spare unlocking methods and a specially designed hedging mode to deal with special situations.
To put it bluntly, the so-called flagship is to achieve exquisite design and original functions that many other products can’t do on the basis of "comprehensive functions and reliable quality" in the general sense. From this point of view, Samsung DR719 is obviously enough to be called one of the best and flagship smart door lock products of the Internet of Things.
