01 Safety Item Testing
The better the deadbolt length and strength, the larger the meshing area with the strike plate, which usually means better safety performance—this is a key indicator recognized by global smart lock safety standards.
Resistance to mechanical technical opening refers to preventing professional personnel from opening the lock mechanically by using technical means (such as crowbars, wrenches), which is a basic requirement for anti-theft locks in major global markets.
Anti-interference performance means that the communication of the smart lock can remain safe under electromagnetic interference, ensuring that operations such as fingerprint recognition and password input are still accurate in interference environments. This is particularly important for areas with complex electromagnetic environments, such as urban central areas in various countries.
Anti-damage alarm means that when the lock detects illegal damage, such as violent dismantling or heavy impact, the lock will immediately trigger the alarm device and notify the user through the networked system. This function is widely required in family and commercial scenarios around the world.

Screen resolution determines the clarity and details of displayed information. The higher the horizontal resolution, the clearer the image display, which is crucial for the visual cat-eye function of smart locks, especially in low-light environments common in various regions.
Minimum usable illuminance refers to the minimum illumination level at which the screen can clearly display images under different lighting conditions, which needs to adapt to the lighting differences in different regions such as high-latitude areas and tropical regions.
Battery capacity assesses the battery life of the sample. During the test, the lock is continuously opened and closed to check whether the sample can meet 3000 uses, which is in line with the long-term use needs of global households (excluding extreme cold or high-temperature environments).

03 Subjective Evaluation
The false rejection rate (FRR) of face and fingerprint unlocking refers to the probability that face and fingerprint unlocking cannot be normally recognized when simulating consumers using them at home. The higher the false rejection rate, the more likely the lock is to fail to unlock, which is an important indicator affecting user experience in global markets.
The timeliness of after-sales service refers to simulating the situation where consumers are trapped outside the door and cannot open the lock by any means (including mechanical keys). They call the brand’s national unified service hotline for repair, and evaluate the response time of the brand’s after-sales service hotline and the timeliness of on-site maintenance services—this is a key factor for global consumers to choose smart lock brands, especially for cross-border purchases.

Reminders for Global Consumers from Shenzhen Consumer Council, Macao Consumer Council, Zhongshan Consumer Council, Futian District Consumer Council, and Bao’an District Consumer Council
01 Choose products from well-known brands. It is recommended to buy visual smart locks through official offline and online stores and other regular channels, and try to choose well-known brands with global after-sales service capabilities. Products from big brands not only have more reliable quality but also more in-place after-sales installation services, which can solve the after-sales problems of cross-border purchases.
02 Prioritize Level B lock bodies and Level C lock cores. The safety performance of smart locks is one of the core factors for purchase. At present, the lock bodies of visual smart locks on the global market are divided into Level A and Level B. Level B locks have stricter safety standards and better anti-theft capabilities. Lock cores are divided into Level A, Level B, and Level C (different from lock body levels). Among them, Level C lock cores have the strictest requirements and the highest safety, which is the mainstream choice in the global high-end smart lock market.
03 Consider “just enough functions”. Visual smart locks often have more functions, higher prices, and greater energy consumption. Consumers around the world can choose visual smart locks with relevant functions according to their actual needs (such as whether they need face recognition, remote unlocking, etc.) and regional usage habits (such as the popularity of NFC in Europe and North America).
