This is definitely an excellent alternative especially when one of the parents needs to work away from home for a certain period of time. Walkie-talkie Features This option provides you with the ability to talk to your little one through the baby monitor. On top of that, you can even play music or transmit almost anything you want to the baby. Even though they put up with a lot of difficulties in caring for their babies, the ounce of reassurance they get from using such devices is more than welcome. Special Features Hearing-impaired individuals are definitely faced with two times the challenge of caring for a baby. Aside from making sure that they can provide for their infants' needs, they also have to deal with the fact that they cannot perceive sounds not even the cries of their own little ones. 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. Baby Monitors and Interference Baby monitors can either be wired and wireless. Both types of devices have their own advantages and disadvantages. For wireless devices though, one of the disadvantages is interference. Interferences can be in the form of intercepted voices from other wireless devices such as wireless phones or static sounds. 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. For example, if you want to leave your baby in the living room for a while, you can get the device from the baby s room and transfer it to the living room without going through the difficulty of moving the wires. The Disadvantages of Wireless Baby Monitors If such devices have advantages, then it is possible that they also have disadvantages.
