These gadgets allow parents to monitor the baby s activities while they are not inside of the nursery or are working at a distance. What Is a Baby Monitor and How Does It Work? A baby monitor is a gadget set that has a transmitter and receiver, which sends either sound or video (depending on the type) for the parent to be able to supervise the activities of the baby while he or she is away. And so, with whatever type of monitor you want to purchase whether audio, video, digital or analog- here are a few qualities that you should always find in a good monitoring device. What to Look For in a Baby Monitor Clarity of the Reception (whether audio or video) and less static is always a good quality for the baby monitor to become effective in child safety. This is definitely an excellent alternative especially when one of the parents needs to work away from home for a certain period of time. Walkie-talkie Features This option provides you with the ability to talk to your little one through the baby monitor. On top of that, you can even play music or transmit almost anything you want to the baby. The most simple baby monitors make use of a simplex transmitter and receiver system. In the baby s room, a transmitter device with microphone is installed while the parents have a receiver device with a speaker. Any sound the baby makes in the room will be transmitted directly to the device held by the parents. So to avoid interference, change the frequency of your baby monitor every once in a while and make sure that the frequency you use does not clash with frequencies of other devices. To change frequencies, wireless baby monitors are equipped with a switch that lets parents change frequency easily. 2) Another way to help in solving wireless interference is to find a proper location for the transmitter as well as for the receiver (baby unit and the parents unit).
