It uses 2.4GHz FHSS technology that offers a private connection between the monitor in your baby's room and the dedicated viewer in your hand. The FHSS connection should minimize interference, and most reviewers say the audio is clear. In BabyGearLab's testing, the reviewer found that the Phillips AVENT had the best audio signal of any of the monitors it tested.

The iBaby’s video and audio quality were among the best in the WiFi group, but like all WiFi monitors, quality and how well it displays real-time action depends largely on your internet quality and speed. Our testers only experienced a delay of less than a second, more noticeable than HelloBaby’s, but nowhere close to Motorola’s three-second delay.
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.

The Infant Optics’s range within our test houses was never an issue, and, as with other monitors we tested, we had to walk outside and down the street before losing the signal. The image quality was good enough to make out facial details 6 feet away in a completely dark room (as it was on others we tested). You can easily add more cameras to the set—you can use up to four Infant Optics add-on cameras, which are separate purchases, usually for about $100. You can mount the camera on a wall easily; pan and tilt 270 and 120 degrees, respectively; and set the parent unit to scan between multiple cameras to keep an eye or ear on everybody at once—another nice feature that’s not unique to this model.
