A baby monitor with a camera consists of a parent unit with a color display and a camera as a baby unit. You can hear and see your baby. A baby monitor with a camera uses infrared LED lights to provide a bright image of the baby room, even in the dark. On a camera baby monitor, you can often also set up that the image only gets activated when motion is detected. That way, you can save energy. Want to keep an eye on several children at once?
