Today, almost everything has gone digital. Cellular phones, computers and even simple household appliances, such as telephones and microwaves, have all switched to digital technology. However, the growing concern of many is whether these hi-tech gadgets can be considered safe for our health, especially in gadgets such as baby monitors that are usually placed in such a close distance to children. These two-way baby monitors not only provide parents with a means to check on their baby, but a means for parent-child bonding as well. What is the difference between the two-way monitor and one-way monitor? 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. This is especially valuable to deaf parents since what they lack in hearing, they can make up for in visual observation. Factors To Consider Before Purchasing A Baby Monitor Buying the most expensive baby monitor on the shelf is not necessarily the best idea that any parent could muster. You have to understand what you really need and determine how to compensate for the capability that you lack without sacrificing anything. This way, you can change frequency bands every time you encounter interference problems. Of course, you also need to factor in the cost of buying a baby monitor. The high-end versions can cost as much as $300 dollars or more. These mobile baby monitors normally feature a video monitoring option that allows parents to keep a closer eye on their babies. " Interference Since a baby monitor is basically a wireless device, it is highly possible to experience interference with the signal. You and your next-door neighbors may utilize similar channels and wind up hearing noises from each other's homes. Cordless telephones may also interfere with your signal. The most basic application of a wired video baby monitor is to provide live video feed from the room of the baby to the room of the parents. This is most useful during the sleeping hours of the parents. With the video baby monitor installed, you can continually monitor your baby without having to stand up and going to your baby in the next room.
