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. When this clashing occurs, wireless interference occurs. There is no total mobility since parents can easily get out of range from the baby unit. But with digital monitors, the range of the devices has been extended making it more possible for the parents to roam around the house without worrying of getting out of range. Disadvantages of Digital Baby Monitors Digital baby monitors do also have their fair share of disadvantages. Every now and then, your baby monitor may compete with these wireless devices for better signal reception. For that reason, it is better to purchase one that features a channel adjustment capability. 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 Disadvantages of Wireless Baby Monitors If such devices have advantages, then it is possible that they also have disadvantages. This is true with wireless baby monitors. The most disadvantageous aspect of these wireless devices is interference. Wireless interference may come as irksome sounds, static sounds or buzzing sounds. It is extremely helpful; especially to parents who cannot possibly stay by their baby s side at all times. The most common type used is the audio monitor. This type receives and transmits sounds produced by the baby to a parent unit so moms or dads could hear the activities of the baby and know if there are any problems while they are at a certain distance. But when examined by professional ghost hunters, they turn out to be ghost voices also known as electronic voice phenomenon. Baby Monitors and Interference Baby monitors can either be wired and wireless. Both types of devices have their own advantages and disadvantages. For wireless devices though, one of the disadvantages is interference.
