The baby monitor, also known as baby monitor or baby monitor, is a wireless family safety protection system. It is composed of two parts: a carer (also known as the monitoring terminal or baby terminal) and a monitor (also known as the control terminal or parent terminal). By placing a carer in Baobao's room, you can monitor the safety of the baby at any time through the monitor. As a family security product, the baby monitor provides real-time monitoring by using the monitoring terminal's every move, every word and every action of the baby. The monitoring results are sent to the control terminal equipment in the hands of the supervisor through the radio waves of analog signals or digital signals, and are restored to video or audio. By using the baby monitor, parents or guardians no longer need to stay close to the baby or child to know their behaviors, avoid frequent checks that affect the baby's rest, and can immediately detect and deal with abnormal situations when they occur. The baby monitor is not only the best daily care product for infants and young children, but also a necessary good helper for caring for the elderly and patients.
The baby monitor greatly improves the freedom and flexibility of parents' life. With this device, parents can handle other affairs in other rooms or even outdoor courtyards. At the same time, they also know the situation of their children very well, so they don't have to worry all the time, making the baby monitor a good helper for parents. L In addition to baby monitoring, baby monitors are widely used for elderly care and safety protection in supermarkets, offices, companies, schools, families, hospitals and other small places.
