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. There are different types of these monitors the audio, video or sensory. 4) Using Digital Monitors The latest technology has spawned a new breed of baby monitors digital. These types of baby monitors have been made to counter any kind of wireless interference. This may cost a little more than the analog versions, but if you do have the money to spare, then try to go digital. Since these channels are not as commonly utilized as the 2.4GHz frequency band, they're less prone to interference. If you have a preference for multiple-handset-capable wireless phones with a handset-conferencing option, pick one that makes use of only the 1.9GHz or 5.8GHz channel. 4.

During night time when the lights are already switched off, you can still continue the surveillance of your baby.
