Here are some tips on how to avoid or, at least, minimize the nuisance of interfering wireless signals in your home. 1. Factor in your wireless phone. In order to reduce the likelihood of interference, pick a baby monitor that works on a different frequency band from your other wireless household devices. By simply positioning one radio transmitter in each room, you can listen to the sounds coming from your baby's room even if you're busy with house chores or other stuff. Then again, this added capability comes with a number of drawbacks. The baby monitors could interfere with each other. For that reason, you need to make sure that they are set in different frequency bands; otherwise, you will only be able to hear irritating electronic screeches. During night time when the lights are already switched off, you can still continue the surveillance of your baby. Low lit environments and dark rooms is not a problem with the help of the night vision feature. Another special feature that some video baby monitor provides is the baby cam feature. With the use of the Internet, parents will be able to keep track of their baby. In the past, baby monitors are only one way transmissions audio from baby s room are sent to parent s receiver and that s it. But with the fast development in technology, baby monitors have also been improved. One of these improvements is the baby video monitor. Baby video monitors, instead of just using audio, now make use of visuals. Instead, they receive muffled, indefinable, and sometimes almost inaudible sounds which resemble voices and words coming from a human. When examined by experts, these sounds can t be technically explained. But when examined by professional ghost hunters, they turn out to be ghost voices also known as electronic voice phenomenon. However, the much-improved two-way monitors can allow parents to talk back to their child with their own portable transmitter. Parents who have children with separation anxiety often prefer this type of monitor, as hearing a familiar voice could usually calm the child. What are the major benefits of getting a two-way monitor?
