Movement monitors operate in several ways. Knowing how they run will help you choose the best movement monitor for your needs. For example, they can run on a few different channels. Changing these channels is one of the simplest ways to reduce interferences, especially if you live in a crowded area. From some points of view, these channels work just like those walkie talkies from you childhood. Some monitors are smart enough to adapt by themselves and readjust every once in a while. If you overlook interferences, your baby’s cries and private chats might be heard by random strangers as well.
