In recent years, with the popularity of smart homes and the empowerment of the Internet of Things, smart door locks have become one of the most popular security options. So, what are the places to pay attention to when buying a smart lock?
1. The more features the better
There are many types of smart locks, and consumers are difficult to choose, so merchants will always add many functions to smart locks, so that consumers feel that they are worth the money.
In fact, the function of the smart lock is not the more the better, each type of smart lock has a way to be pried open, so when selecting a smart lock, in addition to understanding what functions the lock has, but also to understand what anti-pry design the lock has, whether each function can be protected. In addition, new technologies like Bluetooth networking, although very convenient, but there are many risks, and it is the true meaning to choose after the technology is fully mature.
2. The price is not a good deal
There are many smart door lock brands on the market, many product types, large price spans, and uneven product quality.
With the occurrence of the small black box incident, the smart lock industry has also eliminated many brands and manufacturers' products, the reason is that these products lack of protection for the circuit in product design for price advantages, making the product unable to resist the impact of high magnetic field. This also tells us that smart locks also belong to electronic products, too cheap products are difficult to have quality assurance, and lack of after-sales service, when the smart lock failure is also difficult to deal with. Choose smart locks or choose manufacturers or brands with a long history and stable development, they can survive for so long and after-sales products will not be bad.
3. Pay too much attention to product design
Door lock is a product that is used every day and seen every day, it also has certain decorative functions, and every consumer hopes to buy a general high-end atmosphere door lock, which makes people feel bright from the outside. However, the design can only be ranked second, and the first place is still to look at the safety performance of the door lock. The safety and stability of smart door locks are particularly important, whether it is a home smart lock or an engineering smart lock, only safe and stable can ensure normal use.
Choose a good smart lock, security is the first priority, so first look at the design of the smart lock in security, the following points must be there.
1.C class lock cylinder
With the maturity of lock technology, the lock industry has clear testing standards for lock safety.
Be sure to choose products that have passed the national quality test, which is more secure. In terms of lock cylinder, it is necessary to choose a lock cylinder of grade B or above, and the A level should not be considered anymore, and the lock cylinder that can be pried open within a minute should be eliminated quickly. A better smart lock will also add a baffle at the keyhole to hide the lock cylinder and prevent others from maliciously blocking the key hole and causing the lock to not work properly.
2. Semiconductor fingerprint recognition
There are many technologies for fingerprint recognition, and it is necessary to choose semiconductor fingerprint recognition. Although fingerprint copying is not so easy, it is more secure to prevent fingerprint copying from the root. And the area of fingerprint recognition should not be too small, otherwise the sensitivity of recognition is weak, and the large area is definitely faster and more accurate than the small area recognition.
3. Anti-cat eye unlocking design
For the door lock that presses the handle, there is a risk, the criminal can reach into the tool through the cat's eye hole, clamp the handle and press down to open the lock, and the lock is very simple. The smart lock is designed as a free handle, only from the indoor pressure handle can not open the lock, you must hold the button on the handle, while pressing down the handle can open the lock, not only anti-cat eye technology to open the lock, but also to prevent children at home from opening the lock by mistake.
4. Square rod anti-pinch design
Square rod is to drive the lock body oblique tongue and square tongue movement parts, criminals can slightly pry open the panel, reach into the tool to clamp the square rod rotation and open the lock, very unsafe, so the smart lock at the square rod to add a ring design, to protect the square rod is not clamped by the tool, it can improve the difficulty of picking the lock, increase the safety factor.
Finally, don't forget about after-sales service. A good after-sales service can allow you to buy a smart lock without worrying too much about installation, quality and maintenance problems. National door-to-door installation service, lock failure can also know where to go to request after-sales maintenance, no need to find another master, or worry about the merchant does not deal with the problem in time. Therefore, when purchasing, we should look at the brand, and do not choose some brands without after-sales service.
