The analog monitors are the most affordable but are usually still reliable. They work through the radio frequency and use FM signals to transmit the sound. The major set-back of this variety is the tendency of other receivers picking up the same signal that your monitor transmits, thus less privacy and disturbances are possible. There have been a lot of reported cases by parents that they are getting signals from the baby units that are not relevant to the baby or the environment. Instead, they receive muffled, indefinable, and sometimes almost inaudible sounds which resemble voices and words coming from a human.
