Interference may appear in the form of buzzing, static or irksome sounds. Aside from that, baby monitors that come with a video monitoring feature may also suffer from a fuzzy reception. The set is synchronized to a predetermined frequency band that gives off a frequency modulation (FM) signal once it is switched on. More often than not, these portable monitors send out signals between the range of 49,830 MHz and 49,890 MHz. Why do you need to buy one? Mobile baby monitors make it possible for parents to keep tabs on their infants without the necessity of staying awake or standing outside the nursery door all night.
