Description

A home security monitoring system

technical field

The utility model relates to a home security monitoring system, which belongs to a smart home security alarm system.

Background technique

As people's living standards have been greatly improved, higher requirements have been put forward for the protection of their personal and property. However, many communities now pass property management security patrols, set up cameras in the community, install security code doors at corridor entrances, and home anti-theft doors and windows. Such traditional security methods cannot solve the family security problem very well. The current main security systems: 1. Fingerprint recognition, voice-activated recognition, and image recognition according to the camera in front of the door, which cannot solve the problems of window security and acquaintance burglary. 2. Installing anti-theft doors and anti-theft windows affects the visual aesthetics, hinders the needs of fire prevention and disaster relief, and cannot effectively prevent thieves from using vices to cut open and enter the room. 3. Install infrared anti-theft barriers on the balcony windows and doors, so it is impossible to confirm the appearance of the person entering the room, and there is also the problem of system false alarms. 4. A camera is installed in the bedroom to monitor the dynamics in the room 24 hours a day. It is necessary to regularly clear the contents of the previous memory card. Thieves can enter the room by cutting off the power and taking away the memory card. 5. The use of human body infrared sensor for defense is susceptible to interference from various heat sources and light sources, and when the ambient temperature is close to the human body temperature, it will cause the monitoring and alarm system to temporarily fail. According to statistics, in general, burglary will repeatedly step on the spot in advance, and choose to go out through the balcony or the door when the potential target is out, there is no one at home, or around 2 o'clock in the morning, when people are sleeping most soundly.
