Nursery monitors interfere with one another, particularly if homes are close. Certain products, such as portable phones, broadcast to the base unit on the same frequency as the monitor. This results in signals being picked up by the nursery monitor. In addition to the basic transmission, today s monitors have a variety of features to make them even more convenient for parents. Portability Almost all nursery monitors have a portable parent unit that operates from both the base or batteries, and most provide a belt clip for attachment to clothing.
Portability is a key issue with customers, since it provides parents some mobility and freedom.
Some models have the same option on the baby s unit as well. Although most customers don t realize it when they re purchasing a unit, channel selection is probably one of the most important features because it helps eliminate nursery monitors interference. Most monitors have two preset channels, which is similar to having two preset channels on your car radio. If the user experiences interference from within the home or from a neighbor, the unit can be changed to an alternative channel. It is possible to have interference on both channels, in which case the parent may want to speak to a neighbor and ask them to change to a different channel.
