A baby monitor, also known as a baby alarm, is a radio system used to remotely listen to sounds made by an infant. An audio monitor consists of a transmitter unit, equipped with a microphone, placed near to the child. It transmits the sounds by radio waves to a receiver unit with a speaker carried by, or near to, the person caring for the infant. Some baby monitors provide two-way communication which allows the parent to speak back to the baby (parent talk-back). Some allow music to be played to the child. A monitor with a video camera and receiver is often called a baby cam.
Ease of use may not seem like a big deal because once you know how to use something, it won't seem that hard, and after you use it for a while it can feel intuitive even if it isn't. However, with this type of product, there can be a learning curve depending on what kind you choose and how many features it has. While the dedicated monitors were plug in and go options that even grandma can manage, some of them took a little more skill to navigate and learn. The Wi-Fi options, on the other hand, do require some knowledge of technology and the way apps work. With all of them, you will need to set up the camera with your computer or another device, and you will need to set up an account and be able to manage things like Wi-Fi passwords and various settings inside the application. While this may seem like no big deal to some parents, it could be challenging for those that are less tech-savvy.
