(Because most of the smart locks on the market today are a combination of various unlocking methods, including fingerprint unlocking methods, they are collectively referred to as smart locks. )
Next, this answer is mainly from the following two aspects:
First, the main points of purchasing smart locks
I present my mind map of the main points, which is very clear and clear.
Choose the most important points to explain:
1, lock core
Lock core is the most important point in purchasing, and a good lock core can ensure the safety of smart locks. At present, the standard lock core is divided into three grades: A, B and C. The C-class lock core has strong breaking resistance, and it is the best in all aspects, while the A-class lock core is the worst among the three grades, so you must choose the smart lock of the C-class lock core when choosing.
2. Materials
There are many kinds of materials for smart locks, mainly stainless steel and alloy types. Alloys are divided into zinc alloy and aluminum alloy, and zinc alloy is the majority. Both materials have good durability and hardness, and are easy to process, so they are widely used.
3. Fingerprint head
Fingerprint head, that is, fingerprint identification method, is generally a semiconductor fingerprint, and some optical fingerprints are different in that the security of optical fingerprints is worse than that of semiconductor fingerprints.
Semiconductor fingerprints are similar to our mobile phone fingerprints, and optical fingerprints are generally used for punching cards in companies.
4. Battery
There are two kinds of batteries: dry batteries and lithium batteries. Dry batteries are chosen because they are common, easy to replace and have no safety risks.
5. Other safety protection functions
Such as temporary password, one-time password, virtual password, cat's eye protection function.
Second, the smart lock recommendation
Let me explain the smart lock brand recommendation first. The mainstream brands in the market are Xiaomi, Deshiman, Kaidishi, Luke, Philips, Samsung, Yarraa and Gederu. The six models recommended later are also recommended from these brands.
The following suggestions can set a virtual password with cat's eye protection function.
Millet MJZNMS0 1LM
Xiaomi's smart lock has a regular appearance, but its basic quality is still there.
The lock core is class C, made of zinc alloy, and the battery is a dry battery. The fingerprint identification method is semiconductor; There are many ways to unlock, such as fingerprint, password, key, APP and Bluetooth. The thickness of transfer door is 40- 120mm.
Highlights: support for mi band 4/ NFC unlocking of mobile phone, 16 security setting, USB emergency power supply, and 3-year free warranty.
Millet MJZNMST0 1YD
This model will go further in details, mainly including highlights, seven safety tests, timely alarm notification of abnormal situations, NFC unlocking support for Xiaomi's multi-devices, and anti-riot disassembly.
The lock core is C-class, made of zinc alloy, and the fingerprint identification method is also semiconductor. The unlocking methods include fingerprint, password, key, APP and Bluetooth, and the suitable door thickness is between 40- 120mm.
Philips alpha
Philips is also a big brand of smart locks. This is a push-pull type.
The lock core is also class C, and the fingerprint identification method is also semiconductor, but the material is aluminum alloy; The main unlocking methods are fingerprint, password, key and credit card, and the battery is also a dry battery; The difference lies in the thickness of the door, which is between 3.5-4.5mm, 4.5-5.5cm and > 5.5cm.
Highlights: three-year warranty, double verification mode, voice navigation, USB interface of emergency power supply, abnormal alarm setting of lock tongue, and anti-pry detection sensor on panel.
Deschmann Q5
Deschman's model has a special appearance, which is fully connected and fully automatic.
The lock core is class C, made of zinc alloy, and the fingerprint identification method is semiconductor; There are five ways to unlock, namely fingerprint, password, key, APP and Bluetooth. The battery is different, using a lithium battery; The thickness of the adaptive door is also limited to 4- 1 1cm.
Highlights: hide the fingerprint head, protect the fingerprint area, triple anti-interference design, high-profile anti-theft system.
Samsung DP607 ordinary
The appearance color of this smart lock from Samsung is different from others.
However, the lock core is still class C as usual, and the material is also zinc alloy, and the fingerprint identification method is still semiconductor fingerprint identification as usual;
There are fewer ways to unlock, only fingerprints, passwords and keys; The thickness of the adapter door is also 40-110 mm.
Highlights: voice guidance, temporary password setting, doorbell service, high temperature alarm function, battery replacement reminder and silent mode.
Luke TFPL90 1
Luke's appearance is similar to that of Xiaomi.
The performance is similar. The C-class lock core is made of zinc alloy, and the fingerprint is a semiconductor identification mode. Unlocking methods include fingerprint, password, key, credit card, APP and Bluetooth. The thickness of the adapter door is between 40- 120mm, and the battery is a dry battery.
Highlights: automatic locking, five-fold safety sensor settings, push-type anti-lock button to avoid children's accidental touch, and financial-grade encrypted NFC card.
