A baby monitor will release 4 times less radiation than a mobile phone. Do you want your child to be exposed to radiation as little as possible? Choose a low-radiation baby monitor. A low-radiation baby monitor usually uses an analog connection, which means you'll only hear the sounds from the baby room. DECT and WiFi baby monitors release more radiation than an analog baby monitor. These baby monitors often have an Eco mode or VOX function that reduces the radiation that's being released. That way, you can keep an eye on your little one without worries.
