How to choose the right smart lock?
With the popularity of smart locks, more and more people are choosing smart locks as their top choice for new home decoration and old house upgrades. However, if they are not careful when choosing, they can easily encounter various problems such as not being able to install, not being able to unlock, and so on.
As a smart door lock manufacturer, today I will share my own experience to help everyone avoid detours when choosing smart locks.
8 main questions that must be understood when choosing a smart lock
Question 1: C-level lock cylinder is a standard, not a selling point.
Many people ask "Is it a C-level lock cylinder" when buying a smart lock, but in fact, a C-level lock cylinder is only a passing line for smart locks, not a bonus point. The smart locks of legitimate brands on the market are all equipped with C-level lock cylinders, which is the most basic configuration.
What really matters is the type of lock body:
What is a semi-automatic lock: After verification, the handle needs to be manually turned to open the door.
What is a fully automatic lock: it automatically unlocks after verification, making it more convenient.
Purchase suggestion: Semi automatic is more energy-efficient, while fully automatic is more convenient.

Question 2: The more unlocking methods, the better?
Many smart door locks promote "multiple unlocking methods", as if the more, the better.
In fact, there are not many ways to unlock a lock. For most people, the four methods they use in their daily lives are fingerprint, password, card swiping, and facial recognition. Other such as APP unlocking, temporary passwords, keys, etc. are all alternative solutions.
Purchase suggestion: There are two practical methods: fingerprint and password. If you like facial recognition, choose a facial style instead of paying for other unlocking methods.

Question 3: The fingerprint recognition module is more important than anything else.
Fingerprint recognition is the core function of smart locks, and the quality of the fingerprint recognition module directly determines the user experience.
The current mainstream fingerprint recognition modules are:
* Optical fingerprint: an early technology with slow recognition speed, poor accuracy, and the ability to deceive fake fingerprints.
* Semiconductor fingerprint: mainstream technology, fast recognition speed, high accuracy, live detection to prevent false fingerprints.
Suggestion for purchase: It is necessary to choose a semiconductor fingerprint recognition module.


Question 4: Facial recognition is not a must-have.
Facial recognition has been the main feature of smart locks in recent years, and its advantage is that it can unlock things with both hands without putting them down. The disadvantage is that the recognition speed is slower than fingerprints, and it may not be sensitive when the lighting is poor at night.
Purchase suggestion: It is not a mandatory option, it depends on personal preference, otherwise regular styles are sufficient.

Question 5: Should I choose a cat eye camera?
The smart lock with a cat eye camera can view the situation outside the door in real time, and when someone rings the doorbell, it can have video intercom. This feature is very useful for individuals living alone or families with children.
But cat eye cameras also have drawbacks: increased power consumption, privacy and security issues, etc.
Selection suggestion: It is recommended for individuals living alone or families who prioritize safety; Ordinary families can choose or not to choose.
Question 6: The battery life directly affects the user experience
The smart door lock is powered by ordinary alkaline batteries or lithium batteries, with a range of several months to over a year.
Smart locks with short battery life require frequent battery replacement, which is very troublesome. Smart locks with cameras consume more power and generally have shorter battery life.
Purchase suggestion: Choose a model with a battery life of more than six months.

Question 7: Door lock compatibility (the most embarrassing issue is not being able to install it)?
Before making a purchase, it is necessary to measure the following dimensions:
1. Door thickness: commonly 40-120mm.
2. Lock hole spacing: 388/428/458, etc.
3. Installation hole position of lock body.
4. Do you have cat eye holes.
Suggestion for purchase: First take a photo of the door lock hole position and size and send it to the manufacturer for confirmation on whether it can be installed.

Question 8: Remote unlocking is a bonus point
Support remote unlocking, such as Tuya wifi, TT Lock wifi. Some lock PCBA come with built-in wifi for remote unlocking, while others only have Bluetooth function and require the addition of a gateway for configuration to achieve remote unlocking.
This feature is very practical, but not necessary. If not, choosing a regular smart lock is also sufficient.


At last
Smart locks are the first line of defense for home security, and should not be purchased carelessly.
