Actual combat statement: family burglar alarm technology means a big dissection

With the rapid development of China's economy, people's living standards have been significantly improved, and the family environment has improved, making house theft a common practice for some thieves.

1. Anti-theft measures for buildings

(1) Easy access to balcony without guardrail

Ms. Zhang's family used to live on the top floor of Anju Community, and no anti-theft measures were installed on the balcony. Due to the sultry summer, the windows are always open at night. One day, Ms. Zhang woke up in the morning and found that the rice and some food on the balcony were missing, and she felt that the thief patronized her balcony by night. Ms. Zhang was afraid that thanks to the closing of the door leading from the balcony to the room, otherwise the thief would enter the room and commit theft.

Police reminder:

Residents living on the top floor must install anti-theft facilities. The top floor is the target of some thieves. Some thieves are very professional. They can enter the house through small windows in the corridor or through the roof to go down to the top floor with ropes. In addition, there are fewer residents on the top floor. Some thieves will pry open the door lock and enter the room to carry out theft.

(2) Stealing friends' computers by stealing keys

The theft of buildings has now been transformed. Such a case occurred in the Jianguo Community of Dongfeng District. Chen Mou and Liu Mou are good friends, and the two stayed at Chen Mou's house. One day, Chen asked Liu to go downstairs to buy vegetables, and when he returned with the key, he opened the door. When Liu took Chen's key to buy vegetables, he stole a key. A few days later, when Chen went to work, Liu opened the door of Chen ’s house and found a computer that called his own computer. He sold the computer that Chen had just bought.

Police reminder:

Don't give the keys of your house door to outsiders easily. If guests come from home, do n’t put valuables in obvious places, or hide them in invisible places, or do n’t store valuables at home, to avoid giving those who see money to take advantage of the opportunity.

(3) The screen is cut into the room and the camera is stolen

A case occurred in a residential area of ​​Fujin City. The thief entered the room from the second floor and stole the camera.

Mr. Ma likes photography. After taking the first day of photography, he put the camera on the table. I woke up and found that my camera was gone. I looked again and found a long cut in the balcony screen.

The police found that Mr. Ma's house lived on the second floor. There was no protective fence installed on the balcony. There was only a screen window. It was close to the rain outside. The thief easily climbed to the balcony of Mr. Ma's house through the rain. theft.

Police reminder:

The first floor is generally equipped with a protective fence, and the balcony on the second floor is close to the rain ride. The thief can easily climb to the second floor through the first floor protective fence or the rain ride. Therefore, protective measures must be installed on the second floor. Also, do n’t put valuables in the room too close to the window, or put your clothes on the window sill, so as to avoid the thief picking clothes or valuables through the pole, and causing the owner to suffer losses.

2. Anti-theft measures for bungalows

Ms. Zhang's home lives in a bungalow. The bungalow has a courtyard, and the courtyard has a large iron gate. Usually no one is in the house, the door is locked, but the door of the bedroom is rarely locked. One day, Ms. Zhang went out to buy food, and she thought she would come back in a few minutes, only to lock the door. About 10 minutes later, she came back and found that the door was still locked, the room was turned upside down, and the more than 900 yuan in the cabinet was gone. So, she immediately went to Jiadong Police Station to report the case.

The police immediately rushed to the scene for investigation and visit. I learned from the neighbor that when I heard someone knocking on Ms. Zhang ’s door, the neighbor came out and saw that it was a boy of three or four years old. He said that the ball was kicked into the yard.

After learning this clue, the police station added police force, narrowed the range of reconnaissance, and looked for the kickers. It was learned through reconnaissance that there were often a group of young boys playing football in the jurisdiction, all around 16 years old. The police brought the older one back for questioning, and the big boy quickly explained the truth.

It turned out that in the name of playing football, they kicked the ball into the yard of the resident's house to test whether there was anyone in the house. After kicking, they knocked on the door. If there was someone in the house, they called the ball kicked into the yard and asked to pick it up. The owner would not doubt it. If no one knocks on the door, it means there is no one in the house, they jump through the big wall into the yard, and then commit theft. Such cases have also occurred in the Shuangsheng community under the jurisdiction of Jiadong Police Station. Within half a month, a thief patronized five vacancies. Since the houses of some residents' homes in the jurisdiction are often unoccupied, the household heating supplies, welding tools, computers and other daily necessities have become things that the thieves care about.

After discovering that many bungalows were unoccupied, Wang had stolen five homes in a row within half a month. Just when he was going to steal the sixth house, because of his excessive drinking, his feet slipped, fell off the house, and fell into the yard. As a result, the owner of the house came out and asked him what he wanted to do. He said it was fine. Later, the owner of the cottage called the police.

The police at the police station rushed to the scene, captured them, and found many stolen goods at his home, as well as tools for committing crimes.

Police reminder:

The residents of the bungalows should strengthen the awareness of anti-thieves and thieves. It is convenient for thieves to steal and easy to enter and exit. As long as there is no one in the house, the doors in the room and the gate of the yard should be locked. Doors and windows are tightly closed at night, and long-term uninhabited houses must not store valuables, or let neighbors take care of them, take care of them, or check them regularly. If necessary, install monitoring devices or automatic alarm devices.

Third, the assembly of family anti-theft technology

The home security system is an important facility to prevent accidents such as theft, robbery, and fire. Once an emergency occurs, the owner can be notified quickly by phone, so that emergency measures can be taken quickly to prevent accidents or disasters from expanding.

The home security system uses a host computer to connect various detectors through wireless or wired to realize the anti-theft alarm function. The host is connected to the fixed telephone line. If there is an alarm, dial the alarm according to the mobile phone set by the customer or the phone number.

The home security system usually consists of three parts: a detector (also called an alarm), a transmission channel and an alarm controller. The alarm detector is composed of sensors and signal processing, and is used to detect intruders' intrusion or smoke. The device composed of electronic and mechanical components is the key to the anti-theft alarm system, and the sensor is the core element of the alarm detector. The use of sensor devices with different principles can constitute alarm detection devices of different types, different uses and different detection purposes.

Most of our current anti-theft methods rely on civil and physical defense (such as anti-theft doors, iron guardrails, etc.). If technical conditions are available, the use of technical protection methods will get twice the result with half the effort.

(1) Install infrared anti-theft alarm device. When this alarm device is in working state, it can emit infrared light that is invisible to the naked eye. As long as a person enters the light control range, the device will immediately emit an alarm sound. If a thief enters, the residents can immediately find it, but the thief himself does not know Often they are caught.

(2) Install electromagnetic password door locks. When installing this kind of lock, you need to press the password first when unlocking from the outside, otherwise the lock cannot be unlocked; if you pry it open, the alarm will sound when the alarm device is locked. This will disturb people or neighbors in the room, one can scare away the thieves, and the other can capture the thieves.

(3) Actively cooperate and actively participate in the urban community alarm network system. After the user installs this kind of alarm equipment, if there is a dangerous situation (such as burglary), the alarm will automatically send an alarm through the pre-set defense zone, the police station's alarm device immediately automatically displays the user's exact address, and the police can quickly arrive The crime scene was arrested.
