Correct me if I am wrong, but both Surface Pro and Surface 2 laptop have USB 3.0. But the new Surface headphones have USB-C for charging. If that is correct, why would MS make computing devices with incompatible USB ports? You wouldn't be able to charge the headphones on either device. Unless the headphones come with an adapter, it seems dumb to me.
Most monitor systems have an electrical cord or nonrechargeable battery option for the unit in the baby's room. And receivers typically have an electrical cord or rechargeable batteries. Some models are notorious for burning through batteries at an alarming rate. Parents have complained that even monitors sold with rechargeable batteries built in can drain quickly. Our Baby Monitor Ratings , available to subscribers, include an evaluation of battery life. Subscribers can also check out our battery report and Ratings (for subscribers).
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.
Movement products are designed to sense the movement associated with a baby breathing. These products attempt to discern when your little one has not moved within a prescribed period that could indicate that they have potentially stopped breathing. While this may seem like a no-brainer option for parents worried about Sudden Infant Death Syndrome (SIDS), they are not foolproof, have not been approved by the FDA as a medical device, and are known to have false alarms where the baby is fine but then suddenly awakened by a loud alarm. While it is an interesting kind of product, we caution parents that this type of device is not a substitute for safe sleeping practices and doesn't prevent SIDS. However, if you are willing to accept false alarms, it can provide another layer of monitoring to help some parents sleep better at night. Movement sensing products are only useful until babies start to roll over, at which point they become unreliable.
Security: Whether you’re skeptical of people hacking baby monitors or deeply concerned about it (and there are stories!), the bottom line is that some monitors are at more risk than others. A Wired story from 2015 refers to security firm Rapid7’s findings that Wi-Fi–enabled monitors were particularly vulnerable. We figured people would prefer the not-hackable type, and we talked to a security expert about how to protect your privacy.
To test connectivity, we put the handheld unit and the camera in neighboring rooms with 30 feet between them. We looked for lag, choppiness, and changes in the video or sound quality. While we rated it separately, we also did tests to estimate each baby cam’s maximum indoor range. Each camera we tested has a range of 100 feet or more, which is enough for an average-size home.
Wireless systems use radio frequencies that are designated by governments for unlicensed use. For example, in North America frequencies near 49 MHz, 902 MHz or 2.4 GHz are available. While these frequencies are not assigned to powerful television or radio broadcasting transmitters, interference from other wireless devices such as cordless telephones, wireless toys, computer wireless networks, radar, Smart Power Meters and microwave ovens is possible.
