Nowadays, the application of intelligence in life is more and more extensive. For example, when we decorate a house, we can choose intelligent door locks instead of ordinary door locks when installing security doors. In this way, we don’t need to use a key when we go home, but we can unlock it with a password or fingerprint, which is not only convenient, but also very safe. However, if friends don’t pay attention to the following three points when buying smart locks, it may not be as safe as using ordinary locks. If we want to choose smart locks, we must know the three misunderstandings of smart locks!

　　One: Three misunderstandings in the purchase of smart locks

　　1. The more functions, the better.

　　In order to make consumers recognize their products, many merchants will attach many functions to smart door locks, so that consumers can think that they have purchased products with high cost performance. As far as the door opening method is concerned, the common door opening methods of smart door locks are fingerprints, passwords, cards and mechanical keys. Of course, some smart door locks also have iris, face recognition, mobile phone remote, APP and other door opening methods, and even some smart door locks can use bus cards to open doors. Although these ways of opening doors bring us a lot of convenience, some technologies are not very mature and relatively safe, and they are easy to be destroyed by criminals.

　　2. Pay too much attention to product appearance

　　Door locks also have the function of home decoration, and the appearance is of course important, but to give up the safety consideration for the appearance, it is a bit of a waste. Convenience, appearance and function are important, but the core point is always safety.

　　3. The more affordable the price, the better

　　There are many brands of smart door locks in the market, and the price span is also very large. From four or five hundred yuan to eight or nine thousand yuan, many consumers also put a question mark on the price of smart door locks. The function of door locks looks similar, and the cheap ones should also be used. However, many cheap smart door locks have no guarantee system, which looks not bad, but they are basically superficial and the internal things are much worse. In case of problems, after-sales can’t keep up. If the manufacturer closes down, it is very likely that even people can’t be found, which is very risky.

　　Two: the main points of security door installation

　　1. In the process of master’s door-to-door measurement, it should be made clear that a small door should be opened where air conditioning is needed, which is convenient for installation and maintenance. If you don’t like fixed windows, you can do indoor push-pull security window, which will broaden your horizons, but remember to close it at any time during use.

　　2. It is best to install the security window before the last paint of your house is finished. Don’t clean the fashionable security window in the future, and it is better to make up for the paint damage during the installation.

　　3. If you have children at home, you can consider a semi-mobile home security window. This installation method has a slightly lower anti-theft level, mainly to protect children and prevent them from falling downstairs.

　　4. When installing security window, rebar can be used without bending radian, because rebar is hard and difficult to process.

　　5. When installing anti-theft, fix it on the wall with iron expansion screws every 50 cm to improve the adhesion.

　　6. In the process of installing security window, there are requirements for the number of iron expansion screws, and the number of fixed iron expansion screws is not less than 10 per window.

　　7. The screws should be welded internally, and the screws must be screwed on the inner side of the wall. It is best to carry out spot welding to improve the difficulty of dismounting.

　　8. When installing anti-theft, we must pay attention to its security window grid density. When installing in security window, we should understand that the denser the security window grid density, the better.

　　9. During the installation of solid security window, solid rebar shall be used as the core, and stainless steel security window shall be made of solid rebar greater than or equal to 12mm.

　　Friends know the three misunderstandings in the purchase of smart locks. If we plan to install smart locks on the security door after we decorate the house at home, we need to pay attention to these three aspects when purchasing smart locks. Otherwise, the security of smart locks may be poor and the actual anti-theft effect will not be achieved. This is tantamount to buying them for nothing!
