A few days ago, Mr. Zhang, who lives in Wenchang Road, found that his neighbor had changed a new lock. Unlike the lock in our traditional concept, the lock only needs to be placed in the sensing area to identify the lock, and the door lock is automatically unlocked. "It's just like the fingerprint on the unit, it's really new." When asked, Mr. Zhang learned that the neighbor's home had replaced this high-tech lock for theft, and the lock price of nearly 3,000 yuan also made him stagger. It is understood that high-tech locks are not uncommon in the market. In addition to fingerprint locks, there is also an electronic lock that is also popular. When opening such a lock, the sensor point on the key needs to be placed in the sensing area of ​​the lock. The key can be inserted into the keyhole for unlocking. "It seems that these locks are very high-tech, but what about the anti-theft effect?" Mr. Zhang still has such doubts. Locks have a wide range of price tens of times The reporter visited a number of building materials decoration markets in the city and found that at present, there are many kinds of door locks on the market: traditional mechanical locks, super B locks, electronic locks and fingerprint locks, and prices range from tens of yuan to 3,000 yuan. The owner of a lock shop joked that the height of the road is one foot high. Now the thief technology is getting more and more powerful, and the anti-theft performance of the lock must be improved. He suggested that some door locks that have been used for several years should be upgraded and replaced. The reporter saw that the price of electronic locks and fingerprint locks ranged from 1,000 yuan to 3,000 yuan. For the anti-theft effect of such locks, one boss said frankly that the fingerprint lock form of about 3,000 yuan is much larger than the content, and the fingerprint scan is only convenient for the host. No need to pick up the keys. He said that the key to the lock is the anti-theft coefficient of the lock cylinder. "The fingerprint lock is not indestructible." Anti-thief anti-theft needs more security awareness Cao Liu, chief of the basic department of the Yunyan Branch of the Public Security Bureau of Guiyang City, said that most of the residents' door locks are A and B locks installed by the developers when they deliver the house. Some of the older cell locks are mostly word locks or cross locks. At present, the anti-theft locks are usually divided into three levels: A-level, B-class and super-B-level. The transition from AB-level lock to super-B-level upgrade is a major trend in future family safety. Cao police officer said that a professional thief can only open a Class A or Class B anti-theft lock for a few seconds at most. After the crime, the door lock and the lock cylinder can be kept intact. If you want to open the Super B-class lock, the skilled unlocker will take at least three or four hours, and some even have to be destructively removed to open. He also pointed out that from the results of police crackdowns, the majority of victims of theft were installed with Class A and Class B locks, and few electronic locks and fingerprint locks were installed. However, this does not fully prove that the safety factor of electronic locks and fingerprint locks is so high that the thief cannot start. Cao police officer stressed that the price of Super B-class lock is moderate and the safety factor is relatively high. However, no lock is absolutely safe. The so-called "not afraid of thief stealing is afraid of thief", only residents have raised their awareness of security, thieves It won't be awkward. At the same time, social security requires the common maintenance of the whole society, actively participate in the fight against two robs and thieves, group defense and group control, and jointly create a good public security environment. This is the "anti-theft lock" with the highest insurance factor.
