Abstract
A baby monitor has a nursery unit and parent unit. The nursery unit has a controller for generating a privacy code, a microphone for detecting baby sounds and a transmitter for transmitting a signal made up of the privacy code and the baby sounds. The parent unit has a receiver for receiving the signal, a controller for comparing the privacy code to a reference code, and an amplifier and speaker for outputting the baby sounds. The baby sounds are output by the parent unit if the privacy code matches the reference code. The nursery and parent units have a scrambler and descrambler respectively for scrambling the signal.
