Wireless baby monitors are usually equipped with switches that allow parents to change frequencies easily. The next option in fixing interference is by properly placing the baby monitor, both the baby s and the parent s units, in the proper location. What does it mean by proper location? It means that the baby monitors should be placed as far away as possible from other wireless devices. 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. What are the disadvantages of Baby Monitors? First and foremost, baby monitors work more efficiently between ground floor and first floor areas. 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. Video baby monitors, as the name implies, use video footages for overseeing events in the room where the baby is located. It incorporates the technology used by webcams in computers. Instead of only using the simple transmitter with microphone, a camera is installed with it. The receiver, instead of just having speakers, already has LCD screens installed along with them. The video monitor on the other hand works like a tiny TV by having a camera record the baby s movements while the parent could watch on a small screen receiver. 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. 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. It could occur any time, whether awake or asleep. What To Do If You Think Your Baby Has Apnea When your baby is born, he or she is automatically evaluated for any problems in health like defects in breathing.
