design principle: Some people may not understand the specific principle of alarm. Let me explain to you that the function of this product is not to get help immediately by sending out sound alarm, but to prevent it, everyone has heard a saying that "being guilty", as long as people are guilty when doing bad things, so when someone wants to extend their evil hand to you, suddenly, the alarm sound of high decibel sounded. What was his reaction? It must be running, so this is the main function of the alarm, and the second is to attract the attention of people around you through sound and get help! I wish everyone peace!
