Teach you to distinguish the security level of anti-theft door lock by looking at the key

Anti-theft door locks are classified into A-level, B-level and super-B-level. Different door locks have different keys. The higher the level, the greater the anti-theft coefficient.

Waking up early in the morning, I found that more than 2,000 yuan of cash was missing in the living room wallet, and the SLR camera worth more than 8,000 yuan was gone, but the doors and windows were all good ... Thinking of the stolen home on New Year's Day, the citizen Ms. Xia couldn't help feeling afraid.

As the year approached, the burglary cases entered the high-incidence period, and the police reminded that no matter whether someone in the family should lock the doors and windows to strengthen the prevention. I heard that there are thieves who use "tin foil to unlock" to open the door for a few seconds. Many citizens are very distressed. What kind of "general iron" does the door use to make the door safer?

Doors and windows are good, tens of thousands of money and stolen goods at home

Yesterday, Ms. Xia, who lives on the second floor of a high-end community in Zhengzhou, said that on New Year's Day in 2013, the thieves stole her money and tens of thousands of dollars into the room. They didn't know that they were resting in the bedroom.

According to Ms. Xia, her family watched TV and chatted to sleep at 0:00 the next morning. The next morning, when my lover was going out, he saw the wallet in the living room collapsed. There were no more than 2,000 yuan in cash. The SLR camera, ID card, and driver's license in the living room were gone. The family quickly called 110 to call the police. When the police came to investigate, they found footsteps left by the thief at the door.

Ms. Xia wondered: The doors and windows in the house are in good condition, and the locks have not been damaged. Why did the thieves come in? Think again, there are indeed loopholes in the prevention, there is no anti-theft net at home, the window is also slit by the heating, and the living room door is not locked that night.

Afterwards, she heard that there have been several burglary cases in the community recently, most of which were below the third floor, and the doors and windows were intact after the theft.
