The invention discloses a smart home security system, which comprises a monitoring module, a central processing module, a camera module, a locking module, an alarm module, a wireless module and a wireless terminal, and the central processing module is connected with a monitoring module, a camera module and a locking module , an alarm module and a wireless module, the wireless module is connected with a wireless terminal. The invention solves the defects that the smart home system in the prior art is not intelligent enough, poor in practicability and convenience, and detects the safety situation through the RFID reader and the shock sensor, so that the traditional anti-theft net anti-theft window becomes invisible, and at the same time the alarm The situation judgment is more accurate, and the central processing module issues instructions to make each security protection module act, and an alarm situation is generated to the wireless module in time, so that the user can take measures in time to prevent the item from being stolen, so that the intelligence, practicability and convenience of the present invention are improved. Greatly improved, it can meet the intelligent requirements of the home security system.
