To ensure family security, we must do a good job of “three-layer security”, namely, residential area security, residential unit security, and home security. To ensure family security, we must combine personal protection with technical protection:

1. Anti-theft iron doors should be installed in buildings, anti-pry angle iron should be installed in first floor buildings, master locks should be installed in multi door buildings, and burglar alarm systems should be installed for residents.
2. Iron fences should be installed for windows along the street on the ground floor, the spacing between the iron grids should not exceed 15 cm, and the transom and exhaust windows should be reinforced.
3. Before going to bed or going out, check if the doors and windows are locked and inserted.
4. When a stranger knocks on the door, it is advisable to inquire about their identity before deciding whether to open the door, in order to prevent bad people from using the excuse of entering and stealing property.
5. Do not lend the keys to public anti-theft doors to friends or open anti-theft doors for strangers.
6. Do not easily hand over the door key to others. Children should not hang keys around their necks, they should be kept in their backpacks to avoid being discovered.
7. Long term absence from home leaves no trace. If you are not at home for a period of time, do not let the thief notice. There may be many promotional materials and small advertisements inserted on the anti-theft door when the homeowner is not at home. It is best to advise neighbors or trusted friends to regularly clean up these things in this situation, and not to let people know from the appearance that there is no one at home, giving thieves an opportunity.
8. For those who knock on the door of the building to find someone during work, be vigilant to prevent thieves from waiting for the opportunity to commit crimes.
9. To prevent climbing thieves at night, the balcony and canopy design of residents should adopt measures that can prevent climbing or adjacent crossing. The balcony should be enclosed or equipped with anti-theft nets as much as possible.
10. Residents on the first floor or the second floor with an external platform are more prone to picking property from outside the window. To prevent such cases, attention should be paid to closing the window and placing clothing, leather bags, and even mobile phones away from the window or in a place that is difficult for criminals to reach.
11. Store valuable assets properly. Do not put passbooks, credit cards, or other identification documents together. A large amount of cash should be deposited in the bank nearby rather than at home. The password should be a number that is easy to remember, but not a date of birth or ID number number that is easily guessed or tried out by others. Small valuable items such as cash or gold and silver jewelry, if temporarily stored at home, should be placed in inconspicuous rooms and areas where money is generally not stored. For those who need to keep cash at home frequently, a safe can be installed in a concealed location and directly fixed to the wall.
12. Hidden pin anti-theft. In addition to installing a safety lock on the door, a hidden pin can be installed on the door, and inserted before bedtime. If the door lock is pried open and there is a hidden pin blocking it, the thief still cannot enter.
13. Tips for choosing anti-theft doors: (1) Look, the thickness of the steel plate of the door frame of the anti-theft door should be more than 2 mm, and the thickness of the door body should be more than 20 mm. The anti-theft lock must be tested and qualified, and the lock body should be equipped with reinforced steel plates. (2) Touch, the appearance of the anti-theft door should be painted, the feel is delicate and bright, the overall weight is heavy and the strength is high, generally more than 40 kg. (3) Check, to see if there is a safety inspection certificate.
14. Placing items behind the door. Before going to bed at night, you can place a large wooden board or an empty wine bottle that is easy to making noise behind the door. When a thief breaks the door and enters, a loud noise will occur, waking up residents and scaring away the thief.
15. Use of curtains. Thieves often use curtains to determine if someone is in the house and then come to steal. When going to work or going out, not all curtains are closed tightly to ensure safety. You can choose areas of the living room or bedroom that are not visible, such as the hallway or kitchen windows without curtains, or open the curtains of the living room or bedroom by a gap and block the view with a desk lamp or other things, so that the thief thinks there is someone in the house and dare not act recklessly.
16. Using 2 locks. According to research on criminal psychology, once the unlocking time exceeds 5 minutes, criminals will feel restless, nervous, gradually lose confidence, and stop or give up. Imagine adding an auxiliary lock to the doors and windows of a home, which would prolong the thief’s unlocking time and help to end the intrusion.
17. Be cautious when there is an empty room next door. If your neighbor has just moved into a new home and has not yet moved in, and the next door is an empty room, you must strengthen your awareness of prevention and take preventive measures as soon as possible for the adjacent windows and balconies to prevent thieves from entering through the empty room.
18. High-rise residential neighborhood mutual assistance. Strengthen the connection and mutual understanding with neighbors, promptly inquire or stop strangers when they inquire, and then safety precautions can be taken. When going to work or going out, you should greet your neighbors and take care of the safety of your home to prevent theft. Residents can also join forces to arrange dedicated personnel to take turns guarding, or form a building protection team to conduct patrols and duties.
19. Home doors and windows should be checked regularly. Damaged doors and windows should be replaced in a timely manner, and damaged door locks or lost keys should also be replaced in a timely manner. In addition to aesthetics, the main attention should be paid to whether the door frame and door body are sturdy, whether the door seam is sealed, and whether the door body and door frame that fix the lock body and lock buckle are firm and sturdy.
20. Install burglar alarm systems. The burglar alarm system is connected to the alarm monitoring center of the security company, and it will sound an alarm when a thief illegally enters. The security personnel will arrive in a timely manner, allowing you to go out without any worries.
21. If a thief is found, report to the police first. In the face of thieves, wisdom and courage are equally important. Remember not to be a hero, call the police first. When abnormal situations are discovered, if the victim blindly chooses to fight the thief, the thief may choose to attack the victim under pressure, and the consequences will be very serious. Therefore, when facing thieves, one should not be too timid, but also pay attention to certain strategies based on the situation on the scene.
22. Call the police in a timely manner to protect the scene: If your home is stolen, do not panic: (1) Firstly, call the police and tell your name, reason, and location clearly, especially the location must be accurate. If you are not familiar with it, be sure to describe the environmental characteristics of the location in as much detail as possible. (2) Secondly, do not tidy up or clean up household items, do not wander around indoors, and be careful not to touch door handles and locks to avoid damaging valuable fingerprints and footprints. (3) Thirdly, for the traces and items left by thieves, ropes should be used to surround and protect them, and all unrelated personnel are prohibited from entering. Residents can enter and exit through designated passages. After these things are done, wait for the police to investigate the scene. You should know that your protective measures are very helpful for case investigation and recovery of property losses.
