There are plenty of features to pay attention to before checking a baby monitor review website and making a decision. It usually depends on your personal needs. For example, movement sensors represent a very good option. Such sensors are usually placed on the bed, right under your baby. They detect the movement and the receiver is alerted – visually, acoustically or both. Although you may not always enjoy being woken up whenever your baby turns around or moves, the sensors can be deactivated when you are in the next room. Some units also notify you about your little one’s temperature.
