In order to solve the problems that children spend too much time surfing the Internet with their mobile phones, and browsing risky websites affects their physical and mental health, China Unicom launched the Family Guardian-Online Classroom Edition, which has five functions: Internet access restriction, website reminder, online statistics, activity scope and tencent games management. Parents set the time when children are allowed to surf the Internet. Non-allowed time will restrict internet access, and they are not allowed to play games and watch videos. At the same time, you can also receive reminders of children's access to risk websites and statistics of online records, and correctly guide children to surf the Internet healthily. In order to ensure the personal safety of children and facilitate the rapid retrieval of lost equipment, the product also adds the function of displaying the range of activities, and the approximate location of the number of the monitored object can be viewed through the range of the base station to which the number belongs. In addition, cooperate with Tencent's growth guardian platform to effectively manage children's game time and consumption.
