Angelcare AC403-D

General information about the baby monitor

The Angelcare AC403-D reliably monitors your baby’s sleep and breathing sounds. At the same time, it is the lowest-radiation baby monitor on the market. The breathing control mat is suitable for all conventional crib mattresses. The various monitoring functions are individually adjustable. In addition, the Angelcare AC403-D baby monitor has eight channels available for transmission.


In order for parents to make sure that their baby is doing well, the Angelcare AC403-D baby monitor offers quite a few features. The most important is probably the breathing control in the form of a mat. This is placed under the baby’s mattress. However, this does not work if breathing sounds can be detected by other family members nearby. The baby monitor also has other features such as a room temperature sensor, a motion detector, vibration alarm and the integrated night light.


As with all baby monitors, the range varies depending on the environment. In outdoor areas, it has a range of up to 250 meters. It has an audible range control that can be switched off and has eight channels for transmission.

Power supply

It is powered by the AC adapter or rechargeable batteries, which gives parents the flexibility to move around with the baby monitor. Even in the event of a power failure, parents do not need to worry during operation with the power plug, because the Angelcare AC403-D baby monitor then simply switches to battery operation.
