Audio baby monitors enable parents to hear sound emanating from their baby's room, while video monitors let them see what is transpiring there via a built-in LCD screen. While most baby monitors are unidirectional, with one transmitter in the baby's room and one or two receivers at the parents' end, some are bidirectional, enabling parents to transmit audio as well. Advanced baby monitors also offer remote monitoring capabilities over a broadband Internet connection.
Baby monitors can be either wired or wireless. A wireless, or cordless, monitor is comprised of two or more units communicating with one another via an RF protocol – either DECT (1.7GHz-1.9GHz) or WDCT 2.4GHz. The baby monitor can be part of a home telephone system or a dedicated monitoring system. By linking a DECT/CAT-iq dongle to a home PC with Internet connectivity, parents can monitor their baby’s room from a PC at their office or other remote sites.
