From Figure 1, we can see that the 2 balconies and doors are in the most vulnerable areas. The second one is the kitchen and the study room windows (because the study room and kitchen are usually unoccupied, especially at night, they are usually vacant, which can easily become the entrance of thieves). The third is the master bedroom ①, children’s room ② and bathroom ③. So we firstly determined the areas that need to be protected. Then we need to determine the priority of the prevention area (the intrusion position is indicated by the priority of the prevention in the figure)
After the location and area that are vulnerable to intrusion are determined, we need to determine the prevention method and equipment for each defense area. It is better to have all areas protected. But if the environment situation and community security is good, you can only have the main entrance areas protected.
Based on the above setting, we can choose smart detectors or microwave detectors to replace the above ordinary infrared detectors; add harmful gas detectors in the kitchen, 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 issued); the door is equipped with a digital anti-theft lock; the glass is equipped with a vibration detector to further enhance the prevention ability. One thing to note is that, while focusing on new technologies and new products, security products should also focus on stable and mature conventional and reliable ability.
