The DXR-8 uses a secure 2.4 GHz FHSS wireless transmission to ensure privacy, gets up to 10 hours of battery life on a single charge, and can switch to audio-only mode with the camera off to save juice. That said, it has gotten panned for a quickly declining battery life (as well as poor range). Still, that hasn’t stopped 24,000 reviewers from giving it an overall 5-star rating on Amazon. In terms of bells and whistles, it features everything parents have come to expect in a monitor: invisible infrared night vision, (no annoying blue light to wake the baby) two-way intercom, room-temperature sensor, and the ability to work with up to four other cameras.
Sound devices relay what is happening in baby's room via sound only. A great sound option is quiet unless the baby is making noise so that you won't be disturbed by white noise or constant static. This basic monitoring type can be all you need if your goal is being alerted when your baby is crying and needs your assistance. This style can be elementary with sound only like the V-Tech DM111 or it can have bells and whistles like a nightlight, 2-way talk, lullabies, and mic sensitivity adjustment features like the Philips Avent DECT SCD570/10. Most parents can get by with a sound only device as it provides the information you need to determine if your baby needs you or not.
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.
It really depends on what you feel most comfortable with. There are audio monitors that allow you to listen to any noise coming from the nursery, vital monitors that track sleep and breathing and video monitors that add sight to sound. Babylist parents overwhelmingly choose video monitors. The security of seeing what your child is up to—like if they’ve gotten tangled in their swaddle, pulled their diaper off or climbed out of the crib—can be worth the extra cost of a video monitor.
