As a locker who has been in business for 15 years, I have disassembled thousands of smart locks and have drawn up five key points that must be cautious when choosing and purchasing, so as to help you avoid 90% of the dangers:

1. Lock core safety is the bottom line, and C-level is the hard indicator

Must choose C-level lock core: the technical locking time is ≥270 minutes, the key must have double-layer holes and more than two or more tartar flowers (such as snake groove + crescent groove), which is more than A/B Level lock core is 10 times safe

The lock body must be equipped with a protective wall: a built-in stainless steel anti-wall can resist the damage of the electric wall. I have handled three cases of being pried because Missing this device

Emergency key holes should be hidden: I have seen too many cases of exposed lock holes being damaged by water filling, and it is recommended to choose a slitting hidden design

Reject plastic shells: Last year, we handled 7 cases of lock failure caused by plastic shell fragmentation. We must choose the quality of the gel/glass alloy

The tongue should be 304 stainless steel: It is actually measured that ordinary tongue will be worn after half a year of use. It is recommended to choose a three-care structure with oblique tongue + square tongue + reverse tongue

Plate thickness ≥3mm: If it is too thin, it is easy to be damaged by a crowbar. In the case where I was messed up, 80% of the panel thickness is less than 2.5mm

III. Function selection is discussed, these configurations cannot be saved

Semiconductor fingerprint identification: Optical identification can be cracked without flour, semiconductors must be selected to have a temperature/pressure sensitivity

Semiconductors can be cracked in optical imaging. p>

Direct password function: any number can be input before and after the correct password to prevent stealing and reduce the detection ability60% lower password leakage risk

Electric separation structure: Two people were rescued at the fire scene last year, but they were all able to open the door with keys after the electronic part was destroyed

4. Be vigilant about price traps. You cannot save these money

Buy with caution below 1,500 yuan: dismantle A brand of smart locks costs 999 yuan, plastic wheels are used inside, and the motor has a life of less than 20,000 times

Personal facial recognition and choose 3D structure: If you have handled complaints using photo locks, you must choose Bringing live detection (such as Obi\’s Chinese light scheme)

The continuous flight will take more than 6 months: it is recommended to choose an 8800mAh steel battery, and last year, it handled 23 cases of circuit board corrosion caused by battery leakage

<img src=\"https://www.toutiao.com/a7473042611230605836/data:image/gif;base64 ,R0lGODlhAQABAIAAAAAAAAAAP///yH5BAEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

Foot the directed sheet size in advance: Common specifications are 24×240mm/30×240mm, and if the size error exceeds 2mm, it will shake

Select 72 hours to respond After-sales: Handle a complaint about a brand that has not been repaired for 7 days. It is recommended to choose local brands such as Kadishi and Deschmann

Reserve purchase certificate: within the three guarantee period In order to prevent damage, non-humans should replace new products for free, and helped customers with entitlement three times last year

Teacher\’s advice: Last week Just dealt with a case of a smart lock being slandered. The victim bought a 698 yuan raid lock for cheap, but the thief used F

The small black box of electromagnetic = BIL principle opens in 3 seconds. Remember—there is no replacement for safety. Select these 5 points to use it for at least 5 years without any problems.
