SMILE GUARDIAN / smart badge


The Su Yuan case sounded the alarm of the society. In order to reduce the possible emergence of "Su Yuan" in the world, I designed this one that can be hung on clothes and schoolbags when girls go out alone.The product will be connected to the guardian's mobile phone and police station intelligence, and can monitor the child's situation and mood in real time. Once the danger is found, it will quickly locate, record the appearance of the criminal and send it to the police station and guardian, and make a high decibel sound to attract the attention of people nearby. Be able to rescue girls when they are about to be in danger.
