The Babysense 7 movement product is a sensor pad mattress product that isn't portable but seems to have fewer false alarms than wearable products. The BabySense 7 is easy to use and doesn't require much setup or preparation outside of placing the sensor and control unit. This unit even works well after your baby learns to roll over, unlike the wearable options that become less reliable as your little one's age.
For standalone monitors, we found that two features were nice to have: The first is VOX, which mutes the ambient sounds in a room entirely, activating the speaker (and often the video) only when significant sound is recognized. The second feature we appreciated was LED sound meters. These are an excellent, rare feature to keep constant tabs on a baby while muting a monitor and turning the video off (Consumer Reports appreciates these LEDs, too.)
The features we focused on were those we thought either increased the performance of the monitor or made it more user-friendly for parents and increased the odds of getting good quality sleep. We looked for monitors that have sound activation that keeps the parent unit quiet when the baby isn't crying, so parents can potentially fall asleep faster because they don't have to listen to white noise. Some of the monitors were so loud, even at low volumes, that the white noise might keep light sleeping parents awake; this defeats the purpose of having a video product to begin with. We also liked the models with screens that automatically "wake" and/or go to sleep.
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.
The longest battery life for the dedicated products in our review is the Levana Lila, which ran for 12.75 hours in full use mode. The manufacturer claims this unit will work up to 72 hours in power saving mode, but we only tested the monitors in full use. The Infant Optics DXR-8 came in second place with a shorter run time of closer to 11.5 hours. The Motorola MBP36S earned the lowest score for battery life with a runtime just under 7 hours. While not necessarily a deal breaker, there are plenty of other reasons to dislike the Motorola MBP36S, and the battery life is just a small part of a disappointing overall picture (no pun intended).
There are two basic types: audio and video/audio. Some are analog, others are digital. All monitors operate within a selected radio frequency band to send sound from a baby's room to a receiver in another room. Each monitor consists of a transmitter (the child/nursery unit) and one or more receivers. Prices range from about $25 to $150 for audio monitors and about $80 to $300 for audio/video monitors.
