With the continuous development of science and technology and the rising quality of people's lives, the concern for family finances and home safety is also heating up. Therefore, the home security work is still the top priority.
Home security technology
Most of our current anti-theft methods rely on civil air defense and physical defense (such as security doors, iron guardrails, etc.), if there are conditions, the use of technical defense measures will receive twice the result with half the effort.
1. Install an infrared burglar alarm device. When the alarm device is in working state, it can emit infrared light that is invisible to the naked eye. As soon as the person enters the light control range, the device will immediately sound an alarm. If a thief enters, the resident can immediately find out, but the thief himself does not know. It is often awkward.
Second, install the electromagnetic password door lock. When installing this kind of lock, you need to press the password first when unlocking from the outside, otherwise you can't unlock it; if it is opened, the alarm will be sounded when the alarm is locked. This will alarm the people or neighbors in the room, one can scare away the thieves, and the second can also seize the thieves.
Third, participate in the urban community alarm network system. After installing the alarm device, if the user encounters a dangerous situation (such as burglary), the alarm will automatically send an alarm through the pre-set zone. The alarm device of the police station will automatically display the exact address of the user, and the police can quickly arrive at the police. The crime scene was captured and the criminals were arrested.
Home security product selection
The choice of home burglar alarm should be considered in combination with multiple factors such as home area, building structure characteristics, property value and surrounding environment, but there are several general reference standards: wired mode has the advantages of reliable communication, strong anti-interference ability and low device cost. It is suitable for new buildings that can reserve cables in the wall; however, its mobility is poor, it is inconvenient to adapt to the changing requirements of users and products, and the maintenance and replacement of reserved cables is difficult and expensive; wireless mode can be avoided. The connection between the probe and the host affects the interior decoration, which has the advantages of flexibility and simplicity, but also has the disadvantages of being susceptible to various external factors and relatively high cost of the device.
The means to prevent thieves from entering the door is mature, that is, the reed switch/magnet pair is used to detect the opening of the door. However, it should be noted that there are two different alarm triggering modes: instant alarm and delayed alarm. The former can immediately generate an on-site alarm, which can immediately deter the intruder, but if the user does not perform the disarming operation before opening the door, This can result in false alarms and harassment of the user and the neighborhood. The latter type of delay triggering alarm mode will sound a prompt when the door is opened, prompting the user who forgot to disarm to perform the disarming operation in time. If the host does not receive the disarming signal within a certain period of time, the host will then perform an alarm. Obviously, the latter approach is more practical.
