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. However, for many parents who are concerned with the safety of their child, switching to modern technology can certainly be frightening. 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. These questions seem to have no specific and factual answers and so does the question Are EVPs real? A sound is just a sound and it all depends on how they are interpreted. If the sound of a cat is interpreted as a moo of the cow, then it comes from a cow. If an inaudible noise is interpreted as voices of people from the afterlife then it comes from people in the afterlife. And the sensory monitor is a movement detector that alarms the parent when it cannot perceive any movement from the child for more than 20 seconds. How Does It Play A Role In the Safety of the Child? What baby monitors basically do, is allow the parents to know their child s activities and to watch out for any possible problems from afar, especially if the baby is asleep. Needless to say, deciding to get rid of one device in favor of the other is certainly out of the question. What is Wireless Interference? Interference may appear in the form of buzzing, static or irksome sounds. Aside from that, baby monitors that come with a video monitoring feature may also suffer from a fuzzy reception. Wireless baby monitors are usually the gadgets that experience this kind of problem. They experience interferences because of different factors one of which is the use of other wireless devices either in your flat or in the flat of other tenants. Luckily, there are several ways on how to, if not eliminate, at least minimize the existence of interference.
