How Do Baby Monitors See in The Dark?


Have you ever wondered how the best-rated baby monitors are able to create images of a baby’s room when the room is dark? Well, lots of people want to understand how that technology works.

Here we’ll explain how baby monitors use military technology to enable them to create images of a baby’s room when the light low levels in the room are low.

Night Vision Feature

Many baby monitors have a night vision feature that allows the baby’s caretakers to watch the baby from over a long range.

This feature can be turned on in the evening, or the baby monitor can be programmed/set to switch to the night vision feature when the ambient light in the room decreases to a pre-set level.

Near-infrared Spectrum

The images sent to the baby’s caretaker’s iOS device are created by a camera in the baby monitor. The camera is able to create the images by using LED near-infrared light.

The near-infrared light is in the light wavelength of 2500 to 750 nm. It is referred to as near-infrared because it is the part of the infrared spectrum that is close to the visible light spectrum (760 – 380nm).

The near-infrared spectrum cannot be seen by humans. The benefit of using it is that it amplifies the ambient light in the room, and creates images based on that light. Baby monitor cameras can “see” everything in the room, including the baby, clearly.

This is very important when you have two babies that need attention at once.

The problem with near-infrared light is that it can only create images when there is some ambient light in the room. If the room is pitch black, the near-infrared light will not be able to produce enough light for the camera in the baby monitor. Likewise, if you are looking at imagery that is of poor quality, you may be able to improve the quality of the images by adding a small amount of ambient light to the room.

The best part of this is that the amount of light needed to produce good camera images in a “dark” room is quite low, so there is no need to be concerned about the baby being bothered, annoyed, or awaken by the low levels of light needed to create a good camera image.

The near-infrared light is produced by light-emitting diodes (LEDs) that create light or “glow” when electricity passes through the LED wires. Baby monitors can be set to automatically turn on the LEDs when the ambient light in the room decreases to a specific level.

Camera Operation

The camera is mounted on or inside the baby monitor. The LEDs surround the camera and produce light only the camera can see. You can see this feature mostly with digital-based monitors.

The light from the LEDs provides enough light for the camera to create an image. The image created by the camera is sent to an iOS device used by the baby’s caretaker to monitor the baby’s room.


In a nutshell, the baby monitor camera can send the iOS device used by the baby’s caretaker a black and white image of the baby’s room when the room is dark because it has just enough light to create an image.

The baby monitor camera night vision feature makes it easier for people to check on babies without waking them and means that they don’t have to physically go to the baby’s room to check on the baby.
