In American TV series, if we look closely, we will find that foreigners rarely install security doors and security window. According to statistics, 95% of American families do not install security doors.
As we all know, the proliferation of guns has become a cancer of American society. Aren't American families worried about gunmen breaking in? Is there still any anti-theft "artifact"?
Why are there few foreign countries that install security doors and security window?
For outsiders, the question of "whether to use anti-theft equipment" largely depends on the security situation in the region and community. If you live in an area with high crime rate, anti-theft equipment is necessary, unless your family is poor and thieves and robbers are not interested in your family. If you live in a small town with simple folk customs or a rich area far from the city center, the necessity is greatly reduced. Security doors and common ones in security window won't be installed, and you don't have to lock doors and windows when you go home at night. Except for occasional police cars patrolling by, it is basically quiet at night.
Once there is an anti-theft demand, there are many anti-theft devices on the market. The most common are infrared alarm equipment and window alarm equipment, such as the large and thick security door in China, which is relatively rare abroad.
Overseas real estate network understands that infrared alarm equipment is about the size of a mobile phone, and has multiple detectors, which can be installed at all doors and windows entrances, preset passwords, and activated when people are not at home. Once someone enters, there will be about 15 seconds to 1 minute to enter the password. If the password is not entered or entered incorrectly within the predetermined time, an alarm will be given, and the system will automatically notify 9 1 1 alarm. The police usually arrive 5-7 minutes after receiving the alarm. Therefore, even in American and English dramas, you may not see or pay attention. Generally speaking, the equipment input equipment is next to the gate.
Reasons for the rarity of foreign security doors;
First, the utilization rate of apartment buildings is low.
The best place for extra-thick multi-bolt security door is apartment building. Generally, apartment buildings are high-rise residential buildings. Except for the first three floors, the technical risk and cost of burglary through windows are too high, and ordinary thieves are unwilling to take this risk.
In addition, in the United States, for example, in addition to the common apartment buildings in big cities in various States, most other cities are first-and second-floor townhouses (note: a townhouse with about three floors, with private gardens and garages in front and behind) or single-family houses, all of which have several windows, which greatly reduces the role of security doors and the effect is far less than that of infrared alarm systems.
Second, the emergence of other more effective technologies and equipment.
The overseas purchase network has learned that there are many examples, such as Comcast (note: the largest cable TV transmission and broadband communication company in the United States), which provides anti-theft systems and can connect computers and iPhones. The iPhone can directly control the light switch, alarm system and monitor.
Third, standards.
In the United States, even for apartment buildings, better leasing companies now provide standard equipment, full carpet central air conditioning and alarm systems for apartments. All the tenant has to do is call the alarm system company to open the service, and the system will be connected to the home phone. If there is an alarm, dial 9 1 1 directly. Tenants are exempt from the initial installation fee and only need to pay the service fee every month.
Fourth, the cost.
In addition to the above-mentioned standard of free installation fee, the market competition of anti-theft system is also fierce now. Many manufacturers are free of half or full installation fees, and sign a two-year contract with a service fee of 56% off. Some can try for 3 months or half a year for free, and more can be paid in installments. In contrast, the cost advantage of security doors has basically disappeared.
