In the baby s room, a transmitter device with microphone is installed while the parents have a receiver device with a speaker. Any sound the baby makes in the room will be transmitted directly to the device held by the parents. If something is wrong, the parents will definitely know about it. But baby monitors have already come a long way. Digital Baby Monitors and Other Baby Monitors One obvious difference between digital baby monitors and other old baby monitors is that it s digital! This however does not in any way mean that the former is far more superior to the latter. It s just that they use newer technologies to aid parents in taking care of their babies. Often times, parents find it difficult to manage their efforts of doing chores while watching the baby. No one can be at two places at the same time, and it has been one of the major dilemmas of parents who still want to be productive around the house but more importantly want to prioritize their child s safety. This is most helpful to parents who need to be constantly on the go but still want to watch over their baby while doing other productive activities. When are Baby Monitors Useful? Most people think that baby monitors are only useful at night during the sleeping periods of both the child and the parents. 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. Always remember that whether you would prefer an audio, video or sensory monitor, the clarity of sound and video of your unit should be of very good quality for you to effectively monitor your child. " Interference Since a baby monitor is basically a wireless device, it is highly possible to experience interference with the signal. You and your next-door neighbors may utilize similar channels and wind up hearing noises from each other's homes. Cordless telephones may also interfere with your signal.
