- Quick answer: The Owlet Dream Sock measures pulse rate and oxygen saturation on the foot and has FDA De Novo authorization for over-the-counter use. Nanit is a video camera that tracks breathing motion through patterned Breathing Wear, and Nanit says it is not a medical device. The AAP says not to use either kind of monitor as a way to reduce SIDS risk.

## Key takeaways

- The Owlet Dream Sock reads pulse rate and oxygen saturation (SpO2) on a baby's foot; FDA granted it De Novo authorization on November 8, 2023, for healthy infants 1-18 months and 6-30 lbs.
- Nanit is a video camera; with Breathing Wear on the baby, it reads the fabric pattern to detect breathing motion. Nanit says it is not a medical device.
- The AAP says: "Don't use home cardiorespiratory monitors as a way to reduce the risk of SIDS."
- Both need Wi-Fi and a phone app; the Owlet sock needs 2.4 GHz Wi-Fi, and Nanit's display listing says initial camera setup requires a subscription and internet access.
- For video without Wi-Fi at all, a local monitor is the alternative.

   - Cons: The listing says initial camera setup requires a subscription and internet access

This comparison is for parents choosing between the Owlet Dream Sock and a Nanit camera. They do different jobs: the Owlet sock is a pulse oximeter on a baby's foot, authorized by the FDA, while Nanit is an overhead video camera that, with patterned Breathing Wear, watches for breathing motion and says it is not a medical device. Buy the Owlet if you want pulse and oxygen readings, the Nanit if you mainly want video and sleep tracking.

Neither reduces SIDS risk. The American Academy of Pediatrics (AAP) [safe sleep guide](https://www.healthychildren.org/English/ages-stages/baby/sleep/Pages/a-parents-guide-to-safe-sleep.aspx) says: "Don't use home cardiorespiratory monitors as a way to reduce the risk of SIDS." Both makers say their products are not intended to prevent it.

**How we compared:** FDA status is from the [FDA's De Novo record for the Dream Sock](https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/denovo.cfm?id=DEN220091) and its [decision summary](https://www.accessdata.fda.gov/cdrh_docs/reviews/DEN220091.pdf), and Nanit's from [Nanit's own statement](https://www.nanit.com/policies/terms-of-service). Features, Wi-Fi needs and subscriptions are from the makers' pages and the Amazon.com listings (all sold by Amazon.com, in stock in September 2026); we did not test either system.

## What the Owlet Dream Sock measures

The Dream Sock uses pulse oximetry on the foot. FDA's decision summary says it "analyzes photoplethysmography data to identify instances when the infant's pulse rate (PR) and/or oxygen saturation (SpO2) moves outside a preset range, and provides a notification to the caregiver, prompting them to assess the infant."

FDA granted it De Novo authorization on November 8, 2023, as an "infant pulse rate and oxygen saturation monitor for over-the-counter use." The limits:

- It is for infants "1 to 18 months of age and between 6 to 30 lbs."
- It "is not intended for use with infants previously diagnosed with cardiovascular or respiratory disease or conditions."
- It "is not intended to provide notification for every episode" of abnormal readings.
- "The Dream Sock does not detect, diagnose or reduce Sudden Infant Death Syndrome (SIDS) or Sudden Unexpected Infant Death (SUID)."

The authorization followed an FDA [warning letter in October 2021](https://www.fda.gov/inspections-compliance-enforcement-and-criminal-investigations/warning-letters/owlet-baby-care-inc-616354-10052021) that said Owlet was "marketing Owlet Smart Socks in the United States without marketing clearance or approval." FDA issued a [close-out letter](https://www.fda.gov/inspections-compliance-enforcement-and-criminal-investigations/warning-letters/owlet-baby-care-inc-616354-06052024) on June 5, 2024. The Dream Sock sold today is the authorized device.


**Pro tip:** FDA's summary says to "alternate between feet every 8 hours and also after recharging the Sensor," and to check the foot often for irritated skin.

## How Nanit tracks breathing

Nanit is an overhead video camera first: 1080p video, sleep tracking, and sound and motion alerts, per its listing. Breathing tracking needs **Breathing Wear**, a band, swaddle or sleeping bag printed with a pattern that, in Nanit's words, "was custom-designed to enable the Nanit Smart Baby Monitor to accurately track your baby's breathing motion." The camera can "alert you if no breathing motion is detected," and the Breathing Band has "no electronics, wires, or sensors."

Nanit states what it is not:

> "Nanit is not a medical device. Nanit is a connected product designed and intended to continuously learn from the data it collects to help you understand your baby's sleep patterns. It is not intended to diagnose, treat, or cure any disease or other condition, including but not limited to Sudden Infant Death Syndrome (SIDS). False positive or false negative readings about your baby's breathing patterns are a potential risk of Nanit."

It adds that Nanit "should not substitute for the care and oversight of an adult or consultation with medical professionals."

A Breathing Wear sleeping bag or swaddle is used like any other: the AAP's swaddling advice, including stopping when a baby shows signs of rolling, still applies. See our [swaddle guide](https://nurseryproof.com/sleep-nursery/best-swaddles-and-when-to-stop).

## What the AAP says about wearable monitors

> "Don't use home cardiorespiratory monitors as a way to reduce the risk of SIDS. You can buy consumer wellness devices such as heart rate and pulse oximetry monitors. Some of these are wearable. But remember that there is no evidence that these devices, which don't have to meet the same requirements as medical devices, decrease SIDS risk. Don't let these devices give you a false sense of security. It's fine to use one if you want to, just don't use it as a substitute for following all the above safe sleep guidelines."

**Key point:** a monitor changes none of the AAP's safe sleep basics: baby on their back, on a firm, flat surface, in a bare crib or bassinet, in your room without bed-sharing. Our [safe sleep guide](https://nurseryproof.com/sleep-nursery/safe-sleep-guide-whats-safe-in-a-crib) covers what belongs in the crib.

## Wi-Fi, apps and subscriptions

- **Owlet:** the Dream Sock "connects via Bluetooth and 2.4 GHz Wi-Fi" and is "not currently compatible with 5 GHz," per its listing. Owlet says "no subscription is required" for core features; Owlet360 is an optional upgrade for morning reports and comparative sleep data.
- **Nanit:** the camera needs a Wi-Fi router. The display system's listing says "local network viewing ensures the monitor continues working during internet outages," and also that "initial camera setup requires a subscription and internet access." Sleep analytics, personalized tips and video look-back are in the Nanit Insights plans, which start with a free trial.


For video with no Wi-Fi, app or subscription, a local monitor with its own parent unit is the alternative; see our [baby monitors without Wi-Fi](https://nurseryproof.com/sleep-nursery/best-baby-monitors-without-wifi).

## Which to buy

- **Pulse and oxygen readings from an FDA-authorized device:** the [Owlet Dream Sock](https://nurseryproof.com/sleep-nursery/owlet-vs-nanit-baby-monitors#product-B09YVSYGDW).
- **Sock plus camera in one app:** the [Owlet Dream Duo 3](https://nurseryproof.com/sleep-nursery/owlet-vs-nanit-baby-monitors#product-B0FDSHXWYY).
- **An overhead camera with sleep tracking, plus breathing-motion tracking with Breathing Wear:** the [Nanit camera and floor stand](https://nurseryproof.com/sleep-nursery/owlet-vs-nanit-baby-monitors#product-B0FTSL4FXJ).
- **Nanit with a dedicated screen:** the [Nanit system with 8" display](https://nurseryproof.com/sleep-nursery/owlet-vs-nanit-baby-monitors#product-B0GN8YR51C).
- **Video only, no subscription questions:** the [Owlet Dream Sight](https://nurseryproof.com/sleep-nursery/owlet-vs-nanit-baby-monitors#product-B0FDSC6XL6) or a local no-Wi-Fi monitor.

Buy either because you want the information, not as SIDS protection: the AAP says there is no evidence these devices decrease SIDS risk.
