If you live in a small apartment or if your baby's room is only a couple of rooms away, then virtually any type of baby monitor will suffice. On the other hand, parents who own bigger houses or live in multi-story residences require a device that has a longer range. In this way, they will know for certain that the transmitter and receiver will not falter even in extended distances. The company also adds a recommendation that for parents to have total peace of mind, they can position the monitoring device at least a meter away from the child. Going digital in such technologies has many benefits, but there really are minimal risks involved. The digital models of baby monitors have proven over the years to be better in reception as compared to that of the older analog version. Instead of the device being able to help parents, interference turns them into annoyances. So for those who are experiencing this kind of problem, here are a few tips on how to minimize interference with your wireless baby monitor. 1) Signals coming from wireless devices usually clash with other signals from other wireless devices running on the same frequency. 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. Central apnea is very rare in adults but quite common in babies especially those who were born prematurely. Unlike obstructive apnea, this can happen at any time of the day. The third type of apnea is called mixed apnea. This condition is the combination of obstructive apnea and central apnea. This is particularly very common in infants. Since this is the kind of service and specialty they provide, you can be quite sure that you as parents are given the best possible monitoring they can provide. This is one advantage of going pro. Another advantage is that there is usually customer support that will be willing to help you in case you encounter any problems.
