As you'd expect, the talk-back functionality and audio quality on the VTech are great—easily better than the rudimentary talk-back features on our video monitor picks. With the battery lasting about 19 hours on a full charge, this monitor has the strongest battery life of any in our test. Rated to a range of 1,000 feet, it exceeds the range of our pick (700 feet) both as advertised and in practice during tests.
A baby monitor, also known as a baby alarm, is a radio system used to remotely listen to sounds made by an infant. An audio monitor consists of a transmitter unit, equipped with a microphone, placed near to the child. It transmits the sounds by radio waves to a receiver unit with a speaker carried by, or near to, the person caring for the infant. Some baby monitors provide two-way communication which allows the parent to speak back to the baby (parent talk-back). Some allow music to be played to the child. A monitor with a video camera and receiver is often called a baby cam.
During our tests, we found ourselves among the fraction of buyers having problems with the display on the DXR-8. Our first test unit worked fine out of the box, but after a couple of hours running on battery, the display became distorted and nothing would fix it. Likewise, you’ll find a few complaints on Amazon of users experiencing dead pixels after about a year of use (here’s one and here’s another). The good news: Those folks reported that Infant Optics replaced their monitors even though some were out of warranty. In fact, the company consistently receives decent feedback on customer service. Infant Optics quickly replaced our faulty unit (but as a media inquiry, that’s not comparable to typical customer service), and the new unit has performed fine.
You'll get great video quality and an easy-to-setup system with the Safety 1st HD WiFi Baby Monitor. But the real reason to consider this device is a helpful portable audio unit you can carry with you that lets you hear what's going on in the nursery without having to notice and respond to push notifications on your phone. There's little delay when you use the two-way audio feature, and the portable unit will even flash when the camera detects motion for a helpful visual cue to launch the companion app.
The LeFun C2 720P Wi-Fi earned a 3rd place rank thanks to high scores for range and battery life, and impressive results for video quality and features. This monitor earned a Best Value for Wi-Fi monitors for its budget-friendly list price that is the least expensive in the group and its higher rank. This means you can get a great, top performing monitor, at a reasonable price. The LeFun has motion detection, sound activation, 2-way talk to baby, zoom, and a remote-controlled camera with real pan and tilt capabilities. The downside to this camera is a lag time when using the pan and tilt feature, and it is a little harder to use than the other Wi-Fi options we tested, but given the low price, we suspect most parents will forgive these flaws.
But these nursery essentials can be as fussy as the babies they keep tabs on. And like virtually every other household appliance, they are growing increasingly more capable and complex. In addition to conventional video baby monitors that use a camera and a handheld LCD display, often called a “parent unit,” there are now also Wi-Fi-enabled systems that connect to your home network and use your smartphone as both the display and the controller, much like DIY home security cameras. These latter models offer high-defition video, intelligent alerts, and the ability to check on your child from anywhere you have an internet connection.
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.
