How to judge whether face lock is a good brand of smart lock

1、 The lock cylinder determines the anti-theft performance of the lock

Many people think that the biggest advantage of intelligent lock compared with mechanical lock is that it can throw away the cumbersome key, but don't forget to judge whether the ultimate standard of door lock is anti-theft. The Ministry of public security explicitly stipulates that face recognition lock must have mechanical key, in other words, face lock without mechanical key is not in line with national standards. For example, if a face recognition lock without a mechanical key is installed at home, it will be difficult to unlock the lock when there is a fire and the elderly and children ask for help, because the high temperature will melt the internal circuit of the face lock, and the electronic part will fail. Without a mechanical key, you can only break the door, This kind of dangerous situation, no matter how high-tech electronic lock does not have mechanical key to unlock, it is useless.

According to the national standard, there are two levels of lock cylinder: A and B. now the network and some physical businesses like to use the concept of exceeding B level or even C level standard in their publicity. This is just a kind of self boasting behavior of businesses that their products far exceed the national standard.

2、 The quality of the lock depends on its material

The most direct factor affecting the brand quality of face recognition lock is the material used. The appearance of face lock brands may look similar, but in fact, the materials are not the same. The commonly used materials of lock shell are aluminum alloy, zinc alloy, copper and stainless steel.

Due to the stainless steel material has ultra-high hardness and toughness, wear resistance, corrosion resistance, direct polishing or sanding treatment, no electroplating, so environmental protection, health. Other materials must be electroplated. Electroplated products generally contain toxic element lead, which is harmful to human body. The shell of Huarui face recognition lock is made of stainless steel, which is durable and effective against violence.

3、 Appearance determines user experience

Now on the market, some good face recognition locks have the function of free handle. First, the free handle can effectively prevent others from violent damage. When someone presses the handle, the handle is in the free state, isolating the lock body, effectively protecting the internal mechanical parts. In addition, it can also avoid accidental injury of the elderly and children.
