Other Safety Tips - Don't ever use a mere baby monitor to justify your absence. Parental supervision is undoubtedly important, especially if you live in an apartment building where strangers can easily come and go. - 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. Being in this kind of predicament, you may opt to seek for the help of baby sleep apnea monitors. The Different Types of Apneas The word apnea has its origin from a Greek word which means without wind. It is the medical term used to describe the occasional cessation of breathing of a person. Even though it is normal, it may also be a symptom of something more serious that is health related. The audio baby monitor receives and sends sound so that the parent could hear the baby from a distance. The video monitor on the other hand works like a tiny TV by having a camera record the baby s movements while the parent could watch on a small screen receiver. And the sensory monitor is a movement detector that alarms the parent when it cannot perceive any movement from the child for more than 20 seconds. The wide range of options include rechargeable batteries for the portable receivers, remote controls, warning alerts for movements or lack thereof, and monitors with musical capabilities. Of course, you need to thoroughly choose features that suit you and your baby; otherwise, you'll end up spending money for something you don't really need. 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. Instead of only using the simple transmitter with microphone, a camera is installed with it. The receiver, instead of just having speakers, already has LCD screens installed along with them. Video baby monitors have also taken advantage of the current technology of the Internet. With the video baby monitor installed in the room, parents can access the cameras and view the conditions of their babies even when they are at the office.
