But as long as one knows how to set certain prevention methods such as placing the monitor at a safe distance from the baby (at least one meter) and not adding a lot of other appliances inside the baby s room such as televisions or computers, then much harm on the child s health can greatly be prevented. With baby monitors, you can keep track of your baby s even if you are doing something else in the proximity of your house. Types of Baby Monitors Baby monitors have evolved through the years. From the simple transmitter and receiver device, different baby monitors have been developed. Currently, there are two types of baby monitors: video baby monitors and audio baby monitors. Baby video monitors are the advance version of the simplex transmitter and receiver system of baby monitors. In the past, baby monitors are only one way transmissions audio from baby s room are sent to parent s receiver and that s it. But with the fast development in technology, baby monitors have also been improved. In addition, an extra receiver may also come in handy especially if you have a tendency to lose things like phones, remote controls, etc. Facts About Baby Monitors Before you shop for a baby monitor that suits you, try to get the lowdown on these valuable modern-day parenting gadgets. A baby monitor, basically, is a radio transmitter that lets you listen to sounds coming from your baby's room. One-way monitors from the name itself, basically only transmit sound through a single channel wherein parents can hear the sounds that their baby makes from the other end. However, the much-improved two-way monitors can allow parents to talk back to their child with their own portable transmitter. Parents who have children with separation anxiety often prefer this type of monitor, as hearing a familiar voice could usually calm the child. Although the video option seems like a brilliant idea, you still won't be able to stare at the screen all the time. For that reason, you definitely shouldn t sacrifice an excellent sound quality over supplementary features. Keep in mind that the best baby monitors are not always the most costly ones.
