When selecting smart locks, you need to focus on the five core elements of security, adaptability, battery life, unlocking methods and smart functions. C-level lock cores, semiconductor fingerprint recognition, and anti-electromagnetic interference are basic security guarantees, while fully automatic lock bodies, smart cat eyes, low-power emergency charging and other functions can significantly improve the user experience.
Safety performance
Lock core level: Prioritize C-level lock cores (anti-technical opening ≥ 270 minutes), with 304 stainless steel lock bodies, which can resist violent destruction.
Anti-cracking technology: Required anti-black box electromagnetic interference function to prevent hacker attacks;
Supports security designs such as anti-cat eye prying, stay capture alarm, etc.
Biometric technology:
Fingerprint recognition selects FPC semiconductor sensors (false recognition rate <0.001%);
Face recognition requires 3D structured light or binocular infrared technology to prevent 2D recognition from being cracked by photos.
Unlocking method and adaptability
Mainstream unlocking method:
Semiconductor fingerprint (strong versatility)
3D face recognition (suitable for two-handed holding scenes)
Temporary password/NFC card (for visitor scenes only).
Door body adaptation:
Confirm the door thickness (38-120mm) and lock body type (fully automatic/semi-automatic);
Doors with top and bottom hooks need to choose an adaptable model. It is recommended to remove the top and bottom hooks to reduce power consumption.
Battery life and emergency function
Battery selection:
Lithium batteries are better than dry batteries (battery life 8-12 months);
Type-C emergency charging must be supported (power can be powered by connecting to a power bank).
Low battery reminder: APP push + buzzer alarm dual reminder to avoid sudden power outages.
