After that you can switch on all other devices but you should always have the cordless phone switched on last. Another way to fix interference issues is by using digital baby monitors instead of analog ones. The latest digital technology has incorporated some fixes to solve interferences. The only setback with this solution is that it may cost you a little bit more. 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. Although this can be an addition cost, the price you pay in order to take pleasure in its portability is certainly worth it. What are the disadvantages of Baby Monitors? First and foremost, baby monitors work more efficiently between ground floor and first floor areas. However, if your home is made of thick concrete walls or has aluminum siding, then this can terribly decrease the strength of the transmitted signal. Unlike the baby monitors off the shelf, professionally installed ones usually make use of high end gadgets in watching over your baby. The Types of Baby Monitors Basically there are two types of baby monitors: audio and video baby monitors. Audio baby monitors only make use of sounds while video baby monitors make use of a camera and transmitter to send video feeds to a LCD receiver. 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. But it is also important to consider the user s activity, especially if work might require him or her to be of farther distance from the child. Other Practical Features Baby monitors are actually quite new. The idea behind the importance of having one is that you as a parent are afforded with an extra set of eyes and ears. This way, you can keep tabs on your baby even while you're busy with something else. By listening in on your little one, you'll be alerted each time he or she needs feeding or a diaper change.
