Baby monitors work by using a camera and microphone in the baby's room to capture video and audio, which is then transmitted to a receiver unit, typically located with the caregiver.
Baby monitors were invented in the late 1930s. The first commercially available baby monitor was developed by Eugene F. McDonald Jr., the founder of the Zenith Radio Corporation. This early baby monitor, called the "Radio Nurse," consisted of a microphone placed near the baby and a speaker placed near the caregiver.
Baby monitors that operate without Wi-Fi typically use radio frequency (RF) or digital enhanced cordless telecommunications (DECT) technology to transmit audio and video signals.
