Among many smart home devices, smart lock, as the "first checkpoint" to defend family safety, has attracted much attention. Compared with ordinary locks, smart locks are more beautiful, more convenient to use and safer, so they are also accepted by many young people. However, in the huge smart lock market, there are also a lot of shoddy products, so how to choose a reassuring smart lock has become an urgent problem for many smart locks.
To choose a good smart lock, we must first consider its security. If the security of smart locks is not comparable to that of traditional door locks, there is no need to buy them.
When buying a smart lock, we can learn about its lock cylinder level first. Users who know a little about locks know that lock cylinders are classified into three levels, including A, B and C, among which A lock cylinder is the weakest and C is the highest level at present. The key of Class C lock adopts the patented key of double row, computer and compound curve groove, and the technical unlocking time needs to reach more than 270 minutes. It is the lock core with the highest safety factor at present, and the possibility of being stolen is very small unless it is violently destroyed. For example, the TCL IOT smart lock K2 uses the C-class lock core, which is the lock core with the highest safety factor on the market at present, and it is extremely difficult to pry the lock.
Secondly, we can know whether the smart lock has the function of preventing the cat’s eye from unlocking. This function is mainly to prevent thieves from entering through the cat’s eye, using special tools, and pressing the handle hard to open the door lock. Anti-cat-eye unlocking can not only prevent thieves from unlocking through the cat’s eye, but also effectively prevent children at home from opening the door by mistake. It is a safe and humanized design.
TCL IOT intelligent lock K2 has a safe anti-lock setting. The electronic key of the indoor lock body can realize one-key anti-lock and unlocking, and the lock can be unlocked and unlocked by the physical knob in case of an accident. When the safe anti-lock function is started, the door lock can not be opened from the outside, whether by fingerprint, password or key.
In addition, when TCL IOT smart lock K2 encounters abnormal unlocking such as lock picking, it will send alarm information to the user’s mobile phone, so that the user can find the security problems around the house at the first time.
In addition to security, many users who buy smart locks also take a fancy to the convenience of smart locks. At present, fingerprint and password unlocking are almost the standard of all smart locks on the market. As the two most frequently used unlocking methods, the use experience is particularly important. The fingerprint of TCL IOT smart lock K2 can be unlocked in 0.3 seconds at the earliest, and it will give an alarm when the fingerprint is not entered for five consecutive times. In password unlocking, the sum of virtual password and real password can be set to 32 digits. As long as the real password is included in these 32 digits, the lock can be unlocked successfully. Similarly, after entering the wrong password for 5 consecutive times, the smart lock will also give an alarm. In addition to fingerprint and password unlocking, TCL IOT smart lock K2 also supports card unlocking, remote authorization unlocking, one-time password unlocking and traditional key unlocking. It is very suitable for friends who don’t like to bring keys and old people who are easy to forget.
The advantage of smart lock also lies in its unparalleled intelligent function. At present, all major smart home manufacturers are creating a smart home scene where everything is connected. TCL IOT smart lock K2 has built a complete smart home ecosystem thanks to TCL’s precipitation in the smart home industry for many years. It can set the scene through TCL’s self-developed small T Zhilian APP. For example, when TCL IOT smart lock K2 is opened, it can turn on smart devices such as lighting, water heater, air conditioner and air purifier in the porch of the room at the same time, and with the addition of more smart devices in the future, this smart lock can also carry out more complex intelligent linkage.
A good fingerprint lock can not only bring convenience to our life, but also protect the safety of family and property. When a smart lock completes all aspects of brand, safety, convenience and intelligence, it will definitely be the first choice for users.
