In addition to being untested for efficacy, physiologic monitors can increase both your stress and your baby’s stress with false alarms and unnecessary trips to the hospital. Dr. Christopher Bonafide, of the Children’s Hospital of Philadelphia wrote that parents are increasingly bringing healthy babies to the hospital over a false alarm, noting that changes that often set off a monitor are “just normal fluctuations.”
If you struggle with technology and don't need or want to see your baby from any other location besides your home, you might want to stick with the dedicated monitors that require little setup and have fairly intuitive user interfaces. This isn't to say that most people can't sort out the Wi-Fi monitors, but it is undeniably less work to just plug the camera into an outlet and go than it is to sign up and download software applications.
If you're looking for a smartphone-compatible baby monitor that's designed first and foremost to fill that role, Wirecutter calls the iBaby M6S (Est. $135) "the least bad Wi-Fi monitor (so far)," simply because it's "slightly easier to set up than its competitors." Once again, however, experts disagree: Baby Bargains says Nest Cam "runs circles around iBaby when it comes to set up and ease of use."
The main reason you’re going to need a baby monitor is to answer a simple, but time-honored, question: Why the hell is my baby crying? It’s only been in the last 30 years or so that parents have relied on the remote surveillance of their sleeping children. For the eons before that, it was a combination of natural, ear-piercing cries, and sleeping in the same yurt.
We also liked the iBaby because while it allowed us to invite other users to see through the camera — great if you want to give your babysitter access while you’re out — only the person who registered the iBaby monitor has administrator access to all of the features. The administrator can give some privileges to other users, like being able to move the camera around, but they can take them away just as quickly.
Wireless encryption: This ensures that no one else can tap into your monitor’s “feed” and see what’s going on in your house. WiFi-enabled monitors are great for portability and range, but may be more susceptible to hacking. If you go this route, be sure to secure your home wireless network and keep the monitor’s firmware updated. Otherwise look for digital monitors with a 2.4 GHz FHSS wireless transmission.
