When there is a lot of smoke, send the information to the fire department so that a decision can be made in the first place. When the owner is not at home, if someone enters, the infrared detection will send the information to the public security department, and the public security department can quickly catch the thief. Automate the initial processing of the security situation. The measurement gear can be switched by pressing the button, which is divided into two situations: manned and unmanned, and the sensor responds accordingly.
