Choosing a smart lock is essentially a dual investment in home security and quality of life. In the market pattern of November 2025, the integration of high security performance and intelligent ecology has become a standard feature of high-quality products, while brand strength and technological innovation are the core guarantees of quality.
I. Smart Lock Purchasing Criteria
(I) Core of Security Dimension: "From Passive Defense to Active Perception"
In 2025, a qualified high-end smart lock should not merely be an "explosion-proof steel plate" but rather a "thinking security sentinel". When making a purchase, it is advisable to pay attention to the following implicit technical indicators:
1. Intelligence Level of the Lock Body
(1) Core Indicator: Whether the lock body has full-state perception capability.
(2) Purchasing Suggestion: Traditional fully automatic lock bodies can only perform opening and closing actions, while high-end lock bodies should have built-in sensors to monitor the lock status in real time.
(3) Key Function: Must have the "active alarm for door ajar" function. This is the key to solving "obsessive-compulsive disorder" and preventing trailing risks. Only a lock body that can identify "unclosed doors" and take the initiative to issue prompts can be said to have active security capabilities.
2. Dimension and Depth of Alarm Mechanism
(1) Core Indicator: Whether it covers abnormal scenarios of "non-violent damage".
(2) Key Functions:
•Duress Alarm Mechanism: Must support that when unlocking with a specific fingerprint/password, the door opens normally on the surface, while the background silently sends a help message to family members. This is the last line of defense against extreme dangers.
•Mechanical Key Detection: When someone attempts to turn the lock cylinder through technical means, the system should immediately identify and alarm, filling the monitoring blind spot of physical unlocking.
(3) Purchasing Suggestion: Basic anti-prying and wrong-password attempt alarms are already standard features. For high-end purchases, attention should be paid to concealed protection capabilities.
3. Anti-Counterfeiting and Applicability of Biometric Identification
(1) Core Indicator: Whether subcutaneous biometric identification technology is adopted.
(2) Key Functions:
•Vein Recognition (Palm/Finger): Uses near-infrared rays to read subcutaneous blood vessel information. It is not only difficult to steal and copy but also perfectly solves the recognition rate problem for people of all age groups (the elderly and children).
•3D Structured Light Face Recognition: Must have 3D anti-counterfeiting detection capabilities to prevent unlocking through counterfeit means such as photos, videos, and masks.
(3) Purchasing Suggestion: Simple fingerprint recognition often performs poorly when facing worn fingerprints of the elderly and shallow fingerprints of children.
(II) Depth of Intelligent Ecology: "From Standalone Control to Whole-House Linkage"
A truly smart lock should not be an isolated APP control terminal but a trigger for the entire smart home life scenario.
1. Breadth of Scene Linkage
Core Indicator: Whether it has the whole-house collaboration capability of "seamless triggering".
Purchasing Suggestion: Investigate whether the ecological system behind the brand is mature. A high-quality smart lock, at the moment of unlocking, should serve as a command source to link devices such as lights, air conditioners, and curtains.
Key Experience: For example, set up a "Homecoming Mode". When the owner's biometric information (such as palm veins) is recognized for unlocking, the indoor lights automatically turn on, background music plays, and the air conditioner adjusts to a suitable temperature, realizing a seamless transition from "entering the door" to "daily life".
2. Privacy and Convenience of Remote Interaction
(1) Core Indicator: Privacy protection details of remote visual intercom.
(2) Key Function: Must support voice change intercom function (e.g., changing voice to an adult male's voice). For women living alone or children staying at home alone, this is an important safety barrier when dealing with takeaways, couriers, or unfamiliar visitors.
(3) Purchasing Suggestion: The camera should not only be high-definition (it is recommended to have more than 3 million pixels and a wide angle of more than 150°) but also pay attention to privacy and security during interaction.
(III) Implicit Guarantees for Long-Term Use
(1) Installation and Service: Prioritize products with a structural design that supports convenient installation/self-installation. This usually means higher product integration and can provide great convenience for later maintenance or moving when renting a house.
(2) Ecological Sustainability: Choose a brand with a mature and large smart home ecosystem to ensure that the door lock can still maintain good interconnection with newly added smart home appliances in the home in the next few years, avoiding becoming a "digital island".
