We tested monitors daily over a period of several months, in three houses: one nearly 100 years old with plaster walls, plus a newer home with standard drywall construction, and a two-level 1960s home with a driveway on another level from the kids’ rooms. We tried the cloud-based monitors with two routers to be sure that any connection issues were with the monitors themselves and not the Internet connection.
We tested a Nest Camera for the sake of comparison, to see the advantages and disadvantages of a popular security camera versus baby monitors designed expressly for watching babies at home. We have also considered the Arlo Baby monitor, which we’ve seen in demos but not tested firsthand for this guide. Our findings are in Why not just use a security camera? For far more information on all the other similar options—including a detailed look at other Arlo indoor security options, like the Arlo Q—see our guide to the best wireless indoor home security camera.
The Wi-Fi monitors all have lower EMF readings than the dedicated options with the lowest average EMF readings being 0.87 for the LeFun C2 720P Wi-Fi and 0.92 for the Nest Cam Indoor Wi-Fi with the reader 6 ft from the camera. The lowest average value for the dedicated monitors at 6 ft is 1.89 for the Infant Optics DXR-8 and 1.91 for the Philips Avent SCD630.
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.”
A baby monitor's job is to transmit recognizable sound and, in the case of video models, images. The challenge is to find a monitor that works with minimal interference—static, buzzing, or irritating noise—from other nearby electronic products and transmitters, including older cordless phones that might use the same frequency bands as your monitor.
The LeFun is an inexpensive Wi-Fi camera that makes internet watching affordable for almost every family. This useful camera works with your personal device and is the only option here that features true pan and scan features to move the camera around the room remotely. The image quality is also impressive given the lower price and simple design. This camera is a good choice if your house is bigger or you'll be spanning more than 3-5 walls between rooms where range could become an issue.
