With a baby monitor, you're able to keep tabs on your little one(s) during nap time or nighttime, and still go about your day. Generally, the number one benefit provided by the best baby monitors are peace of mind, followed closely by the benefits of security and convenience. Plus, since homes and habits vary, a baby monitor may have additional uses, like allowing you to monitor how long it takes your preschooler to fall asleep, keeping track of playtime, or even using it as a pet cam.
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.
Yes and no, it depends on what you want your device to do and what levels of EMF you are willing to accept. If you are looking for video and sound then you're in luck, all of the video products offer both and products like the iBabyM6S can give you crystal clear visuals with sound and fun baby specific features. If you are interested in sound and movement, only a handful of movement products come with sound, and they are all mattress style devices. If you want movement, sound, /and video, then you are limited and potentially introducing high EMF levels to your baby's nursery. The BabySense 7 is offered as a package with a camera, but the EMF levels were high in our tests making it one we aren't big fans of. To avoid this, and to get the best of the best options, we suggest combining two products (movement and video) and incurring a slightly higher cost to avoid higher EMF. Movement products are only good up to about six months or when your little one begins to roll over by themselves. Because movement can lead to false alarms and can't take the place of safe sleep practices or reduce the occurrence of SIDs, we think parents can get a good night's sleep with a video product with sound and forgo the movement options if budget is a concern.
Most people don't have unlimited data plans for their smart phone, and are surprised to see very high data usage after just a few hours of streaming their wifi baby monitor. With HD video, you can go through a couple gigabytes of data in just a few hours, so keep that in mind. If your phone is connected to wifi that won't matter, but if you're using 3G or 4G LTE cellular service, you will definitely have slow video and tons of data usage.
Even though the jury is still out on the effects of EMF on the human body, this doesn't mean parents need to wait for more definitive proof before making thoughtful adjustments that err on the side of caution. Given that exposure compounds over time and with an increased number of devices emitting, you can help limit baby's exposure by turning off devices when they are not in use, unplugging wireless routers at night while children sleep, and keeping products as far from your baby as possible when in use. Even if you are not convinced that there is potential for harm, it certainly can't hurt to make choices that potentially increase the health of your home.
