1. How secure are smart door locks?
Compared to traditional door locks, smart locks generally offer higher security.
Taking LinDun as an example, the LinDun Touch1 uses the highest national level C security lock cylinder and adopts a true mortise lock structure that penetrates the door body, which can ensure that it cannot be unlocked by technical means.
The dual-line alarm system and free telephone alarm can deter criminals who want to forcibly break or pick locks, preventing the door from being damaged by lock picking.
2. Are network-connected smart locks vulnerable to hacking?
It cannot be ruled out that some smart lock manufacturers, in order to reduce costs, have neglected relevant protections, making them vulnerable to technical attacks. For example, many smart lock products have been opened with a "black box" (Tesla coil). However, the probability of finding a professional hacker to crack the lock with a computer is far less than finding a professional locksmith. Therefore, even lower-quality smart locks are more secure than traditional locks.
The LinDun Touch1 has made significant investments in technological research and development, adopting a financial-grade security chip and meeting the national cryptographic level 2 standard, ensuring worry-free use for users.
3. What are the advantages of smart locks over traditional mechanical locks?
No keys required, making travel easier and simpler.
Comprehensive protection makes life safer.
Compared to traditional mechanical locks, the biggest advantage of smart locks is not that they are safer, more convenient, or solve more pain points, but that they change people's mindset and bring about a better and new way of life.
4. How can I understand the parameters of a fingerprint lock?
1. False Rejection Rate (FRR): The probability that a fingerprint lock will refuse to record a valid fingerprint;
2. False Acceptance Rate (FRR): The probability that a fingerprint lock accepts a fingerprint that is not recorded.
3. Fingerprint recognition speed: The fingerprint recognition time reflects a company's technical strength. The national standard requires fingerprint matching time to be within 3 seconds, while semiconductor fingerprint recognition technology generally takes less than 1 second. The Lindun Touch1 achieves a recognition time of 0.3 seconds.
5. Why can't some smart locks recognize fingerprints?
Over the years, fingerprint recognition technology has undergone continuous evolution, from the first generation of optical fingerprint recognition to the second generation of capacitive fingerprint recognition, and now to live fingerprint recognition technology, spanning three generations.
Many manufacturers are still using first- or second-generation fingerprint recognition technology, so they often cannot recognize fingerprints that are worn or degenerated by the elderly.
The Lindun Touch1 smart lock not only adopts live fingerprint recognition technology, but also uses a 192*192 ultra-large fingerprint recognition sensor that far surpasses its competitors. Combined with AI self-learning algorithm, it can effectively prevent fake fingerprints, solve various fingerprint problems, and has a safe recognition age range of 5 to 75 years old.
6. Where does the power of a smart door lock go?
It is mainly used for fingerprint recognition and LED password display.
7. How long does the battery last, and what happens when it runs out of power?
A typical smart lock with 4 batteries has a battery life of about 6 months, while a smart lock with 8 batteries has a battery life of about 1 year. The Lindun Touch1 has a battery life of up to 15 months and has a low battery reminder function. If the user forgets to replace the batteries after the low battery reminder and the lock runs out of power, the mechanical key or a USB power bank can be used for emergency unlocking.
8. Is the installation complicated? Can I install it myself?
Installation isn't too difficult; you can install it quickly by referring to our installation tutorial. However, if it involves drilling and cutting holes in the door, we recommend that you hire a professional to do it.
9. Does a smart lock need to be connected to Wi-Fi?
Some smart locks require a gateway for connection, but LinDun smart locks use IoT cards, which do not require WIFI or a gateway to bind with a mobile phone and realize various functions.
10. Issue with brute-force unlocking of the "Little Black Box" (a type of electronic lock screen).
The "little black box" is actually a Tesla coil. Some smart lock manufacturers, considering costs, did not implement electromagnetic protection measures, thus making it vulnerable. Most well-known brands can defend against Tesla coils, and the LinDun Touch1 is even immune to Tesla coils, preventing them from affecting it in the slightest.
