The BabySense (and other mattress sensors) require a hard surface under the mattress to work, and they don't work with all mattress types so you'll need to research your mattress to ensure it is compatible. This option is also not good for travel because of these special considerations. This product doesn't have a parent unit which means the alarm happens in the nursery with your little one and could be traumatic to sleeping little ones. If you want a movement device that works well and has a longer life than the wearable options, then the BabySense 7 is a great way to get the job done with minimal fuss.
In addition to monitoring your kids, you can use the camera’s two-way talk to soothe your child (smart for when you sleep train), and it also comes with Intelligent Motion Alerts to let you know if something’s happening in the room. You can also choose to record video footage on an SD card (not included) if you want to use this product as a nanny cam.
Security: Whether you’re skeptical of people hacking baby monitors or deeply concerned about it (and there are stories!), the bottom line is that some monitors are at more risk than others. A Wired story from 2015 refers to security firm Rapid7’s findings that Wi-Fi–enabled monitors were particularly vulnerable. We figured people would prefer the not-hackable type, and we talked to a security expert about how to protect your privacy.
If you sleep in the same room as your baby or live in a small enough space that you can always hear or see what your baby is up to, you probably don’t need a monitor. Otherwise, most parents enjoy the convenience a baby monitor provides—instead of needing to stay close to the nursery or constantly checking on your child, you’re free to rest, catch up on Netflix or get things done around the house during naptime. Monitors can also double as a nanny cam to keep an eye on your child and their caretaker.
