Portability Every now and then, people may share a similar opinion when it comes to size. Some consider smaller devices to be more excellent than larger ones.

However, if your home is made of thick concrete walls or has aluminum siding, then this can terribly decrease the strength of the transmitted signal. Parents who own baby monitors have also reported instances of interference. From time to time, their receivers are able to pick up signals from their neighbors' wireless devices baby monitors included. Since these digital devices make use of signals like electro magnetic waves, they may cause health problems to babies especially when they are at that stage when growth and development is on "rapid mode." A solution developed to counter this problem simply states that parents should put the baby monitor as far away as possible from the child without sacrificing the quality of monitoring.
