You might ask that why would you need a baby monitor? Even though it has become an obvious question now, baby monitors are the newest innovation for the busy parents. This application gives the parents the facility of keeping an eye on the baby even if they are not present with the baby all the time.
A baby monitor is something that you can use to listen to even the remotest of the noises made by your infant. The baby monitors are primarily used to keep watch on your baby when they sleep in separate rooms or when you are away from your baby. The system comprises of a radio transmitter and a receiver system that come with a camera, microphone and speaker. The microphone is put near the baby and the receiver system is to be kept with you.
The device has a frequency within the range of 49 to 50 megahertz but there are some models that have a frequency as high as 900MHz. There may be a few times that the baby monitor gives a third party the transmitted signals in their receiver. There are many choices of bands to avoid this situation. The wireless baby monitor has no cord or wire attached to it. You can even get baby monitors with cable instead of a radio signal and for that, you will need a main wiring.
