If you want to get things done while your baby dozes off in another room, then purchasing this nifty gadget is certainly the way to go. Concerned parents, like you, also have the option of setting up multi-room baby monitors. Multi-room Monitoring A good number of baby monitors only have one radio transmitter and one or more portable receivers that make it possible for parents to listen in on their babies all day and all night long. One problem of analog baby monitor devices is the fact that there are instances when neighbours can actually tap in to the signal of your baby monitors and listen. With the digital technology, privacy is kept since it broadcasts private signals that only you, the parents, have access to. Another dilemma that has plagued analog baby monitors before is the range. A typical baby monitor set consists of two parts: a radio transmitter and a portable receiver. The radio transmitter must be positioned 8 to 10 feet away from your baby's crib. Then again, you can always position it closer to the baby for better reception of sounds. The signal picked up by the radio transmitter is then passed on to the portable receiver, which can be carried effortlessly around the house. Because of this trend, as well as the necessity for better portability, a good number of modern baby monitors are currently equipped with ultra-small receivers. Most baby monitors these days also come with receivers that have belt clips. This feature allows parents to carry the device around without much effort. You can be in the kitchen or in the garden and still be able to keep an eye over the baby since you are not limited with a wire. It is important to know though that these devices also have a limit to their range. Special Features Some video baby monitors have special features. This is mostly based on the manufacturer and provider of your baby monitor. And mothers are truly blessed to have baby monitors in their aid that would ease their burden.
