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. And thus, parents who often find themselves caught up in the middle of work, can now simply talk to the child and calm him down without physically being next to him. The talkback feature can also help maintain the bond of the parent and child, despite the parent being at a certain distance. Parents could sing their lullabies or read stories while they do the laundry or while they clean the house. If the parents sleep in a different room from the baby, it would prove to be impossible to be able to monitor him or her perfectly unless you wake up every minute and check up on your little tyke. So the best way to do this is to use a baby monitor. With this kind of device, you can monitor your baby as if you were actually right there beside him or her. Obstructive apnea is most common in babies and children. It is caused by obstructions in the airway such as adenoids and enlarged tonsils. This is quite dangerous especially for babies since it usually happens during sleep time. And as babies, they still can t articulate whether they are already experiencing symptoms of the condition. This is expected of course since you will be given the best possible baby monitoring system they can provide. Of course, if you have the money for it, then this would not be much of a problem. Another minor disadvantage of this kind of baby monitoring is that you have to confide with the company if you want something to be changed positions, monitoring gadget, monitoring system, etc. With the digital technology, privacy is kept since it broadcasts private signals that only you, the parents, have access to. Another dilemma that has plagued analog baby monitors before is the range. There is no total mobility since parents can easily get out of range from the baby unit. But with digital monitors, the range of the devices has been extended making it more possible for the parents to roam around the house without worrying of getting out of range.
