With the innovation and upgrading of technology, face recognition has been widely used in various social security work, such as stations, banks, hotels and large-scale conferences that need security. In the field of smart home, the cool combination of face recognition and smart locks is gradually being accepted by consumers.

　　In order to keep up with the times, it is indispensable to keep an eye on the latest developments in smart technology-related industries. In July, Sakura Smart Lock released a new automatic 3D face recognition smart lock and made its debut at the Guangzhou Expo in 2020. As a technology controller, how can I miss it! So, after a personal experience at the exhibition, I started decisively. The following is the product experience and the use process. Do you want to know whether the cherry blossom R9 3D face recognition smart lock is reliable? Let’s take a look.

　　This is an exhibit at the exhibition. It is low-key and elegant bright black. It doesn’t feel amazing in appearance, but it can be said to be very attractive. The simple style design of one-piece straight plate and the forging of zinc alloy panel material make it wear-resistant and not easy to leave fingerprints. It is installed on the door of the house, and it has both faces and products. The scene also attracted many onlookers.

　　At the scene, I experienced the face recognition function of Sakura R9. When someone approaches and enters the recognition range, the door lock will respond. The whole process from power-on to face unlocking is no more than 0.3S, which is very intelligent and fast. According to the staff, the 3D TOF face recognition solution adopted by Sakura R9 comes from AI Xin Intelligent, with 3D TOF camera and AI smart chip on the hardware and live body detection and face recognition algorithm on the software, which is a complete set of solutions with completely independent intellectual property rights. Among them, the 3D in-vivo detection algorithm has passed the enhanced authentication of the Bank Card Testing Center, and has financial payment-level security standards.

　　By collecting the complete face contour and depth information, combined with the living body detection algorithm, Sakura R9 face recognition automatic intelligent lock can effectively resist attacks such as two-dimensional images, videos, headshots and masks. So in the process of use, I tried to unlock it by photos, videos, etc., but the experimental results prove that the anti-counterfeiting performance of Sakura R9 is really good, at least this little trick with zero cost can’t be fooled.

　　Because door locks are often installed in corridors, some people will worry that weak light or dark environment will affect the effect of unlocking faces. Therefore, I also did relevant tests below, and found that the 3D TOF near-infrared camera used by Sakura R9 can accurately identify faces and quickly unlock them, regardless of outdoor glare, backlight or dark night in the corridor. It is worth mentioning that Sakura R9 also has the function of adjusting the infrared trigger time selection, which can avoid the embarrassing situation that strangers passing by accidentally trigger the door lock recognition, and ensure the safety of residents all day round.

　　For smart door locks, battery life will also directly affect the experience. Sakura R9 is equipped with two large-capacity batteries with a capacity of 5000mAh. Because it has not been used for a long time, it is impossible to know its specific power consumption. However, according to the official information, Aixin Zhineng’s intelligent face recognition module can realize zero power consumption in standby state, reduce the overall power consumption by improving the recognition efficiency in working state, and the alternate use of two batteries can also solve the worries about battery life.

　　Sakura R9 supports seven unlocking methods, including fingerprint, password, encrypted proximity card, mobile phone remote, mechanical key, double authentication unlocking and so on, which can meet the unlocking needs of the whole family in different situations in daily life. I won’t introduce the other unlocking functions one by one, but it can be said that each unlocking method has a corresponding functional design, which can improve the overall safety of the product. Interested friends suggest that you can start with a good experience. If you need a reason to change the face recognition smart lock, I think it is enough to have three items: "living detection function", "strong environmental adaptability" and "super battery life".
