Since the end of last year, in the urban area of ​​Luoyang, there have been many cases of property infringements such as "smashing car glass and stealing property in the car". Among the few arrested, Pan always used the most characteristic of committing crimes at night. According to Pan ’s statement, the tool he used to smash the glass was a screwdriver, and the speed of the crime was extremely fast. “The crime can be completed in about 2 seconds.†There is no choice for theft of vehicles. steal". From April 2013 until his arrest, Pan had committed 105 violent crimes. Compared with Pan, Li and the other two accomplices are more targeted in their crimes: "targeting" luxury cars to start and carry flashlights. When committing the crime, the three people will take a motorcycle, and after the "investigation" of the roadside vehicles, they will commit the crime. The entire crime process will only take 2 to 3 minutes. After questioning, Li Mou committed a total of 13 crimes, most of which were valuables such as mobile phones and computers.
1. Car theft cases have the following main characteristics:
(1) The time of committing crimes is short, because the thieves understand the internal structure of the motor vehicle and can crack the car anti-theft system, so they can complete the unlocking and ignition procedures of a car in two or three minutes;
(2) It is easy to escape from the scene, and can escape from the crime scene calmly and quickly after the theft is successful;
(3) The alarm time of the case is lagging, because most of the thieves commit crimes at night. When the owner finds that the vehicle is stolen, it is already the next morning.
(4) The crime of car theft presents a trend of gang and intelligent development, and the gang has a clear division of labor, forming a one-stop operation mode of theft and sales;
(5) The time for burglary is mostly between midnight and 4 a.m. At this time, people are more sleepy and not easy to wake up. Patrol and security personnel are also more sleepy at this time, vigilance is reduced, and the prevention work is relatively weak;
(6) The burglary sites are mostly dim places with low light and few pedestrians. The vehicles parked in these sites can easily become the prey of thieves.
It can be seen from these frequent cases of theft of cars that it is necessary to install a car anti-theft alarm for your car. Car anti-theft alarm is a multi-functional product, which can not only act as an anti-theft alarm, but also have the functions of remotely starting the tail box, remotely opening and closing the door, remotely opening and closing the window, remotely starting the engine, and remotely locking the engine.
When the car is in an alarm situation (such as illegal start, door vibration, and system damage), the system immediately calls the owner's preset alarm phone (mobile phone, landline), and sound and light warning, lock the circuit / oil circuit, let the car Unable to start when disarming. In case of robbery or car robbing, the owner can press the concealed button if he can't get away, the system will immediately call the emergency help phone preset by the owner, and can answer the police call to stop the car and stop the car. If the owner can get away from the vehicle after being robbed, he can use any phone to enter the system and use the password to counter-control the parking of the robbed vehicle, shouting, etc.
Second, the trick: how to prevent theft of cars
(1) Don't avoid "accounting for small losses and eating big losses": please ask the public to store their vehicles in regular parking lots or places where they are supervised. Do not park vehicles on remote roads to save a few yuan in parking fees. Especially at night, try to place the car in an area with bright lights or covered by monitoring equipment.
(B) Do not avoid "no one has anything in the car": When no one is in the car, do not put items in the car, especially leather bags, computer bags and other items.
(3) Never put a "mysterious veil" on the car: the vehicle should not be attached to the solar film as much as possible, even if it is attached to the solar film, it should be attached to the lighter color solar film.
(4) The most important one is to consolidate the car's anti-theft alarm system, so that even in the middle of the night, if the car is stolen, the car owner can even know and take security measures.
Since China's reform and opening up, people's living standards have continued to improve, and cars have become an indispensable part of people's lives. Having a beloved car, it is often like opening a "Pandora's box". Will follow one after another. Since the first T-type Ford car was stolen in the world, car theft has become one of the most common crimes in society today. Dear car owners, when indulging in the new concept of life brought by your car, do n’t forget to provide your car with anti-theft security facilities.
