A baby monitor, sometimes called a baby monitor alarm, is an electronic device used to hear soft sounds made by an infants. It is designed to produce sounds of alarm in case of sudden noises or in case of a medical emergency. An audio baby monitor usually consists of a receiver unit, installed near to the baby, with a microphone attached to it. The microphone takes the incoming sound wave and converts it into sound. Then it sends the sound to the speaker of the receiver unit, so that it can be heard by the baby.
There are various types of baby monitors available in the market. You can use different varieties of the same for monitoring your baby, in case there are some problems. Some baby monitors operate through your mobile phone or your online applications while others have their own apps. Some of them are fully-contained and work just like an audio CD player; they play recorded soft sounds of an infant breathing, giving you a full and clear idea about his/her well-being.
Some baby monitors have both audio and video monitor capabilities. For example, you can hear the baby’s breathing even when you are not at home or even if you are away from the house. You can also see the baby while he/she is asleep by using the video monitor. You can hear the baby’s soft and quiet moans and the baby’s deep and smooth voices. There are also baby monitors that have a night vision capability and can capture images or video while the baby sleeps.
Some baby monitors use Infrared technology to detect body heat of an infant, so they do not need to be plugged into electricity. This technology is quite expensive but these days most of the baby monitors use infrared technology. The other type of monitors uses ultrasonic waves, which cannot be detected by the human eyes and thus cannot be seen in the dark. Most of these video and audio monitors come with the additional feature of “white-listing”, which means that the monitor will only record images that have been seen earlier in the day or night. The baby’s sleep schedule can be easily established by viewing the images taken every 30 minutes during his/her sleep.
Baby monitors that do not have built-in web cams have the added advantage that their operation is more private. These kinds of monitors usually have built-in receivers and amplifiers for video as well as audio input and output, allowing it to function as a personal camera. The Wi-Fi module on these baby monitors allows the users to connect it to their laptops or wireless internet equipments through a wireless connection such as USB or Bluetooth. They can then view and control the monitor through their devices.
The best baby monitors now offer features that make them stand out from the other ordinary baby monitors. One of the best features is the ability to see the baby’s heart rate and respiratory rate with its on-board sensors. This way, parents will know when their child wakes up and needs feeding. In addition, other added features of some advanced monitors are the ability to play educational videos or record live television shows, etc. Some of the most preferred wearable monitors even allow the monitoring of baby’s temperature during different stages of its growth and even give it reminders about to take his/her medications. Most of all, it allows monitoring of the baby’s progress in breathing and the exchange of body fluids.
