These devices have two components, the transmitter and the receiver. Transmitters are being placed 8-10 feet within the baby or closer if possible. Sounds coming from the baby are being picked up and a signal is then transmitted to the receiver. On the other hand, receivers are being carried around the house or place somewhere that is accessible to the mother or whoever it is designated to keep watch of the baby. On top of that, you can even play music or transmit almost anything you want to the baby. Some doting parents also make use of this feature to calm their babies down by talking to them over the baby monitor. Also, when your child is old enough to speak, you can surely have chats by means of this nifty device. Wireless Baby Monitors: Solving Interference Problems Issues of interference with wireless devices have been the long time concern of parents who use wireless baby monitors. Instead of the device being able to help parents, interference turns them into annoyances. 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. Simpler monitor models will do for smaller houses, but you may need a more sophisticated monitor system for a larger house. The lifestyle and the type of work that you have to do around is also another important factor to consider, especially if your work requires you to be farther away from your baby s room and you may need a monitor that covers the range, particularly a portable one. Sensory monitors even send alarms whenever it cannot detect movement from the baby for 20 seconds or more. Even the simpler models of these monitors like the audio monitor at least keeps the parents aware if their baby needs them, especially when the child cries. With this technology, parents are given a way to make sure that their baby is safe especially during times when no one is left inside the room to watch the child. Instead of just being able to hear your baby, you can now actually talk back to him or her. There are even some devices that will let you send commands to the baby s device to play different music to hush him or her back to sleep. Both types of baby monitors, audio and video, can either be wired or wireless.
