One of the primary uses of baby monitors is to allow attendants to hear when an infant wakes, while out of immediate hearing distance of the infant. Although commonly used, there is no evidence that these monitors prevent SIDS, and many doctors believe they provide a false sense of security. Infants and young children can often be heard over a baby monitor in crib talk, in which they talk to themselves. This is a normal part of practising their language skills.

Before buying or registering for a baby monitor (or any wireless product), be sure you can return or exchange it in case you can't get rid of interference or other problems. If you receive a monitor as a baby-shower gift and know where it was purchased, try it before the retailer's return period ends. Return policies are often explained on store receipts, on signs near registers, or on the merchant's website. But if the return clock has run out, don't feel defeated. Persistence and politeness will often get you an exception to the policy. Keep the receipt and the original packaging.
The dedicated monitors did not score as well as the Wi-Fi products for features. It isn't that they don't have features, it's just that they don't offer as many, don't have features that make the camera easier to use or the features they have don't work that well. All of the dedicated monitors have 2-way communication, but they all also can only be viewed on the parent device that comes with the monitor. Some offer temperature sensors and lullabies, but most of them don't provide motion detection or great zoom. The highest score for features for the traditional video products was 5 of 10. Two monitors managed to earn the 5 rating, with the Infant Optics DXR-8 being the highest ranked overall with a feature score of 5. However, this monitor did not score well overall, or in key metrics, we think are essential for a good video monitor. So despite having a high score for features, we still would not recommend this monitor to a friend.
Microphone sensitivity: There’s a difference between hearing your baby cry, and hearing every little noise. All baby monitors have the option to turn down the volume, but some offer thresholds for parents who are more comfortable with only hearing the biggest upsets, and prefer not to hear the self-comforting noises their baby makes as they fall asleep.
This is a light or beeping sound that lets you know that you've reached the monitor's range limit. If you have a model without this feature, static might be the only indication that you're out of range. (A monitor's range can vary due to your home's size, its construction materials, and other factors.) The greater the range, the better--especially if you plan to take your monitor outside.
