DIY home burglar alarm technology and design reference

    Modern society pays more and more attention to family security, especially new high-end residential buildings, because they are more likely to attract the interest of thieves, and generally modern anti-theft devices are installed. So, what should a safe and effective home security system look like?
　　
　　Home anti-theft technical means
　　
　　At present, the anti-theft means of ordinary families are mainly human defense and material defense (such as anti-theft doors, iron guardrails, etc.). It is recommended to use technical prevention means to achieve a safer and smarter effect. It is generally recommended to install infrared anti-theft alarm devices, electromagnetic password door locks, and electronic network alarm systems.

　　
　　Electromagnetic password door lock: When installing this lock, you need to press the password first when unlocking from the outside, otherwise you cannot unlock it; if you pry it open, the alarm device on the lock will sound an alarm. This will alarm the people or neighbors in the room, which can scare away the thieves and capture them.
　　
　　Actively cooperate and participate in the urban community alarm networking system. After the user installs this alarm device, in case of dangerous situations (such as burglary), the alarm will automatically sound an alarm through the pre-set defense zone, and the police station's alarm receiving device will immediately automatically display the user's exact address, so the police can quickly dispatch to the scene of the crime and capture the criminal.

　　-theft system configuration design
　　
　　How should a family start when it comes to anti-theft systems? The following is a design plan for the configuration of a home anti-theft system for everyone as a reference.
　　
　　Step 1: Determine the scope of defense according to the room situation:
　　
　　In a home, the two balconies and the front door are the most vulnerable to invasion; the second is the windows of the kitchen and study (because the study and kitchen are usually unmanned, especially at night, they are easy to become the entrance of thieves); the third is the master bedroom ①, the children's room ② and the bathroom ③;
　　
　　at this point, we have a clear idea of ​​the areas that need to be guarded, and at the same time, the priority of the defense areas has been determined.
　　
　　Step 2: Determine the defense zone and the defense method and equipment
　　
　　for each defense zone. After knowing the locations and areas that are vulnerable to invasion, you should decide the number of defense points based on your surrounding environment, community security measures, family environment and other factors as well as your economic situation (of course, it is best to defend all the defense areas that are easy to invade). Here, we temporarily take the defense of all the above areas as an example to configure various anti-theft equipment. You can increase or decrease the relevant equipment according to your specific situation:
　　
　　① Economic configuration: 2 infrared detectors, 2 door magnetic detectors, and 1 host.
　　
　　The economical configuration can realize the following functions: When the doors and windows of the main door, study, and kitchen are opened or pried open, causing the door or window leaf to shift more than 1 cm, or when a human body enters the bedroom④ and living room from the balcony in a defensive state, the corresponding detector will drive the alarm. After receiving the alarm signal, the host will turn on the high-pitched alarm and dial the owner's mobile phone, neighbor's phone and other pre-set phones to alarm;
　　
　　② Basic configuration: On the basis of the above economical configuration, one infrared detector is installed in the children's room, living room, and study, and one door magnet is installed on the bathroom window. In this way, we have completed a basic home anti-theft system, and at the same time, dual detection equipment is installed in key defense areas (main door, study). The equipment is as follows:
　　
　　1 host, 4 detectors, 3 door magnets.
　　
　　The basic configuration can realize the following functions: when the doors and windows of the main door, study, kitchen, and bathroom are opened or pried open, causing the door or window leaf to shift more than 1 cm, or when a human body invades from the balcony, children's room, and study under the defense state, at the same time, due to the double defense of the main door and study, the prevention effect can be effectively guaranteed.
　　
　　③ Functional configuration:
　　
　　In order to solve the problem that the basic configuration cannot better protect the balcony and windows, we install infrared anti-theft fences on the balcony and windows and remove some indoor infrared detectors. The equipment is as follows: 1 host, 4 pairs of infrared anti-theft fences with 3 beams, 1 detector, and 1 door magnet.
　　
　　Functional configuration can realize the following functions: In the configuration, we use infrared anti-theft fences outside the balcony and windows to deploy defenses, which can timely alarm when someone approaches the balcony and windows, and keep the intruders outdoors to avoid direct conflicts with the owner after the intruders enter the room, so as to better protect personal and property safety.
　　
　　Step 3: Optional equipment and other optional equipment to enhance prevention functions:
　　
　　Based on the above configuration, we can choose smart detectors or microwave detectors to replace the ordinary infrared detectors above; add harmful gas detectors in the kitchen, and add linkage lighting control equipment in the living room (when someone approaches the window, the lights in the living room will automatically turn on when the alarm is triggered); install digital anti-theft locks on the door; install vibration detectors on the glass, etc., to further enhance prevention capabilities. One thing to note is that while security products pay attention to new technologies and new products, they should also pay more attention to stable, mature, conventional and reliable products. In the case of a relatively good security environment or economic constraints, we only set up defenses for the main door ①, balcony ②③, kitchen ④, and study ⑤: Among them, wireless door magnetic detectors are used for the main door, kitchen, and study, and infrared detectors are used for defense in the living room and bedroom.
