The Spring Festival is approaching, and it has reached a period of relatively high incidence of infringements such as theft and fraud. In this critical stage of public security prevention, the reporter interviewed the police and related prevention experts.
We first paid attention to home security. In order to understand and prevent new methods of burglary, the reporter interviewed Mr. Zhang Hongjun, a senior researcher at the China Unlocking Technology R&D Center and a technical consultant of China Locksmith magazine.
Equipment and awareness must be strengthened
"Do you use the 'security door' of the house for a long time?" Zhang Hongjun raised this question to everyone. He later said that some housing companies in the process of project construction in order to control costs, usually choose some low-cost doors. Such a door can only be called an "engineering door", and it is recommended that the house should be replaced after renovation. Zhang said that when the locksmith installed the screw of the door lock, the screwdriver accidentally slipped onto the metal door panel of the security door. This force could pull the door plate out of a hole. How can this quality "security door" prevent violent destruction of thieves? Zhang Hongjun suggested that the home should buy a security door with better quality. The security door should have a design to prevent damage to tools such as crowbars and chisels.
In addition, the focus is on the door lock. “Do you guess the price of the cheapest lock cylinder?†Zhang Hongjun’s answer is 9 yuan. Some lock manufacturers are trying to cut costs by using low prices to seize the market. These manufacturers will reduce the copper content of the lock material, even with iron and aluminum or even plastic. Such low-cost locks are also unusable.
With good equipment, you must have good anti-theft habits and awareness. Zhang Hongjun said that even the best locks, if there is no anti-lock, its anti-theft function is also very small. The anti-theft equipment is important, and the awareness of theft is more important.
Beware of new methods of burglary
Speaking of the awareness of theft, Zhang Hongjun talked about the bad habits of some people. Some people are used to hanging the keys around their waists, and others like to put the keys on the coffee table or table in public. Zhang said that most mobile phones now have camera functions. The criminals can take a key with a mobile phone as long as they are not prepared.
Zhang Hongjun emphasized that this modus operandi is from real cases and the technical threshold is not high. "Even if the thief does not have a key, he can easily obtain the key of the victim's house by paying a high price of one or two hundred yuan, so that he can easily get in and out at any time." In the past, some "work hard" The thief can even make a similar key by observing the tooth of the target key, and there is always one that can open the target lock. Experts suggest that you don't hang your keys around your waist or let them go, it's best to use a key case.
Zhang Hongjun gave the reporter a video. The experimenter in the picture used the violent destruction of the lock. It took only 1 minute and 20 seconds to open a security door. Zhang Hongjun said that this is the latest cracking technique. There is no problem with the security door and the anti-theft lock core, but it does not block the violent destruction of the thief. The problem is on the inconspicuous lock cover. The thin lock cover does not protect the hard lock and does not protect the precision lock cylinder. To guard against this type of breaking, you can replace the lock cover with a tamper-proof cover with a higher material strength.
Everyone is alert to prevent loopholes
In the past year, Zhang Hongjun also collected a lot of thieves burglary. For example, driving a luxury car to hide people's eyes and ears into the community of theft; modified liquefied gas tanks used to collect crime tools and stolen goods, dressed as gas workers mixed into the community theft; renting a house in the community as a stronghold, find out the living rules of other residents, then start Wait. This requires the community security to take up the responsibility, pay attention to the strangers entering and leaving the community, and strictly perform the registration duties for the residents of the community, including the renter.
Many thieves will go through a number of steps and then choose the right target to steal. Advertising flyers inserted in the door or door handles may become their mark. After leaving the leaflet mark many times, I confirmed that the owner had left the door, and the thief was confidently and sneaked into the indoor theft. Citizens who want to travel far to the New Year can entrust their trusted neighbors or relatives to regularly take away the flyers and newspapers at the door.
Security nets for windows and balconies are important, and the vigilance of anti-theft is more important. Zhang Hongjun suggested that everyone establish a harmonious neighborhood relationship with their neighbors. No matter who discovered the suspicious stranger in the corridor, always ask a few more words, maybe you can scare off the thief who is preparing to commit the crime.
