But baby monitors have already come a long way. Today, different baby monitors have been developed which make use not only of sounds but of images as well. A great example of this is the video baby monitor. Video baby monitors make use of cameras instead of just the usual transmitter with microphone device. All they need is a computer with Internet access and voila! Instant video feed direct from the baby s room. The other type of baby monitor is the audio baby monitor. This is the descendant of the basic uni-directional system used by basic and usually old monitors. These new types of baby monitors however have been integrated with new technology. The next option in fixing interference is by properly placing the baby monitor, both the baby s and the parent s units, in the proper location. What does it mean by proper location? It means that the baby monitors should be placed as far away as possible from other wireless devices. This includes cell phones, cordless phones, and routers. And as babies, they still can t articulate whether they are already experiencing symptoms of the condition. Symptoms of this type of apnea include snoring, labored breathing, gasping for air, and changes in color. But the cardinal sign of obstructive apnea in babies is restlessness. Another type of apnea is central apnea. - Do not position a baby monitor's transmitter or receiver near water. Like any electronic device, baby monitors can cause an electrical shock if not used properly. - Adhere to the manufacturer's strict instructions at all times with regard to the usage and the placement of baby monitors inside your home. Multi-room Monitoring A good number of baby monitors only have one radio transmitter and one or more portable receivers that make it possible for parents to listen in on their babies all day and all night long. If you prefer to have one radio transmitter in every room, there are actually a smaller number of choices.
