A camera or a number of cameras are installed in the baby s room and live video feed are transmitted to a TV or LCD receiver. These video devices can either be wired or wireless devices. The most basic application of a wired video baby monitor is to provide live video feed from the room of the baby to the room of the parents. As a rule, you need to place the radio transmitter within 10 feet of the crib so that it can pick up even the slightest sounds made by your baby such as breathing and movement. You can then carry the portable receiver around during the day or just leave it plugged in at the side of your bed at nighttime. The chances of interference are doubled if next-door neighbors also make use of wireless baby monitors. Fortunately, there are several ways on how to resolve interference issues when using baby monitors in blocks of flats. 1) Change The Frequency of Your Device Wireless devices such as baby monitors are created to have the ability to change frequencies. What baby monitors basically do, is allow the parents to know their child s activities and to watch out for any possible problems from afar, especially if the baby is asleep. Through this, they could at least do their usual work without having to feel worried that their child might not be safe inside the room alone. But the cardinal sign of obstructive apnea in babies is restlessness. Another type of apnea is central apnea. This is usually caused by defect in the part of the brain the controls breathing. In babies, this could be a congenital defect. Central apnea is very rare in adults but quite common in babies especially those who were born prematurely. In choosing a monitor, the right range or bandwidth must be considered properly. If it would be used in a bigger house, then a wider range is required. A smaller house or apartment might not need as much range especially if one lives in an area where there may be a lot of interference such as cell phones and other monitors that could disrupt the signals.
