A baby monitor is a baby monitoring device designed to provide parents with real-time monitoring and security of their babies. Here are some common features and functions of baby monitors: Video surveillance: Baby monitors are often equipped with cameras that transmit live video via wireless signal to the parent's monitor or mobile device. In this way, parents can observe the baby's status at any time and ensure their safety and comfort. Sound Monitoring: In addition to video, baby monitors feature built-in microphones and speakers so parents can hear what's going on in their baby's room. This way, any emergencies or needs of your baby can be detected and responded to immediately. Temperature and Humidity Monitoring: Some advanced baby monitors also have temperature and humidity sensors that monitor the temperature and humidity of the baby's room to ensure the indoor environment is suitable for the baby's health and comfort. Smart Alerts and Notifications: Baby monitors are usually equipped with smart alerts, such as cry detection, motion detection, and more. When the monitor detects a specific sound or movement of the baby, it will automatically send a reminder to the parents, so that the parents can react immediately. Night vision: In order to see your baby in dark environments, many baby monitors are also equipped with night vision, which uses infrared light technology to provide real-time images in black and white or color. Cloud storage and remote access: Some baby monitors support cloud storage function, which can store videos and other related data to the cloud, so that parents can access them remotely through mobile phones or computers without geographical restrictions.
