They cost within ten dollars of each other and do completely different jobs. The Nanit Pro watches the crib and grades the sleep; the Owlet Dream Sock reads pulse and oxygen with FDA De Novo clearance behind it. What each actually measures, what the subscriptions really cost, and which one fits the worry you have.
Our verdict
Most parents should get the Nanit Pro Camera — it answers the question most parents have: what’s happening in the crib right now.

The price gapThe two ranges overlap
Each bar is an estimated price range, on one scale from ~$250 to ~$300.
We read BabyGearLab’s lab-tested monitor rankings for both products, the American Academy of Sleep Medicine’s report on the FDA’s De Novo clearance of the Dream Sock, and the American Academy of Pediatrics’ standing position on home cardiorespiratory monitors, then checked all of it against Nanit’s and Owlet’s own current listed pricing and subscription terms. Prices verified 11 August 2026. We haven’t run either monitor in a nursery ourselves; the performance and safety claims come from BabyGearLab’s lab testing and the FDA clearance documentation we cite. Prices are always moving, so every button and link pulls the live listing.

The camera that grades the night for you
Get it if you want to see what is happening in the crib and will act on sleep data.
Skip it if the thing keeping you awake is her breathing, not her schedule.
The Nanit Pro Camera mounts above the crib rather than beside it, which is the whole design argument: you see the entire mattress and where on it your baby has ended up, instead of a corner view of a sleep sack. Nanit lists the system at $289.99 with the overhead floor or wall stand. What arrives in the box works without paying Nanit another cent: live 1080p streaming, sound and motion notifications, background audio, two-way talk, room temperature and humidity, and Breathing Motion Monitoring.
Two costs are easy to miss. The first is the subscription. Nanit Insights is optional, but the sleep analytics people buy this camera for get thin without it: the free Sleep plan covers three months and then runs under $10 a month, Memories is $120 a year for two days of continuous video history and 30 days of sleep analysis, and Milestones is $300 a year for seven days of video and unlimited analysis.
The second is Breathing Wear. Breathing motion is read optically from a printed pattern on a Nanit band, swaddle or sleeping bag, so nothing electronic touches your baby, but the garment is required for the feature and runs about $30 in sizes your baby will outgrow.
BabyGearLab’s lab testing scored the Nanit Pro 76 overall with 8.0 for video quality, and singled out sound as its weak point at 5.0, the lowest among the higher-end monitors they tested. They also flagged it as expensive with limited indoor range, and did not give it an award this round. That matches the honest read: it is a good camera with a mediocre microphone, and it depends entirely on your router.
Against the Dream Sock, the Nanit’s real advantage is longevity. A camera keeps working through crib-climbing and the toddler bed. The sock is done at eighteen months.

The only cleared infant pulse oximeter you can just buy
Get it if the anxiety is about breathing and oxygen, and a number on a screen is what settles it.
Skip it if you want one device that lasts past toddlerhood, or you want to see the room.
The Owlet Dream Sock is a fabric sock with a pulse oximeter in the cuff. It reads pulse rate and oxygen saturation, streams both to the Owlet Dream app, and triggers lights and an audible alarm on the base station if a reading falls outside a preset range. Owlet lists it at $299.99, and unlike the Nanit there is no tier above that: live readings, sleep history and health notifications are all included. It is also HSA and FSA eligible, which quietly takes a bite out of the price for a lot of families.
The FDA angle is the reason this product is different from every other consumer sock, and it is worth stating precisely. In November 2023 the FDA granted the Dream Sock De Novo clearance, and as the American Academy of Sleep Medicine reported, that made it the first over-the-counter medical pulse oximetry solution cleared for infants.
The clearance covers monitoring and displaying pulse rate and oxygen saturation and notifying caregivers when readings fall outside preset ranges, in healthy infants aged one to eighteen months weighing six to thirty pounds. Owlet was clear about the boundary too: the prescription BabySat, not this, is the product for infants who need medical monitoring under a physician.
What the clearance is not is a SIDS claim. The American Academy of Pediatrics does not recommend home cardiorespiratory monitors as a strategy to reduce SIDS risk, and nothing about the De Novo pathway changes that. Buy the Dream Sock because seeing a number helps you sleep, not because you have been told it prevents something.
BabyGearLab’s top video-monitor pick is the Owlet Dream Duo 2, the $400 bundle that adds a camera to this sock, scored 86 and praised for excellent noise cancellation, with a stationary camera and the price as the knocks. Which is the ceiling here: on its own, the sock cannot show you the crib.

Yes, if the thing keeping you up is breathing and oxygen, and a number on a screen is what settles it. About $300 is the whole price: no subscription, HSA and FSA eligible, and the only over-the-counter infant pulse oximeter with FDA De Novo clearance. It has one job. There is no video, it is outgrown at around eighteen months, and the clearance covers displaying vitals and notifying you, not preventing anything; the American Academy of Pediatrics still does not recommend home monitors as a way to reduce SIDS risk.

No. In November 2023 the FDA granted the Dream Sock De Novo clearance as the first over-the-counter medical pulse oximeter for infants, covering the display of pulse rate and oxygen saturation and notifications when readings fall outside preset ranges, in healthy babies aged one to eighteen months and six to thirty pounds. That is a clearance to measure and notify, not to prevent. The American Academy of Pediatrics still does not recommend home cardiorespiratory monitors as a strategy to reduce SIDS risk, and safe-sleep practice remains the actual intervention.
No, and the difference matters. The Nanit reads breathing motion optically, by watching a printed pattern on a Nanit Breathing Wear band or sleepwear through the camera. The Owlet measures pulse rate and blood oxygen saturation with a pulse oximeter against your baby’s foot. One is a visual estimate of movement, the other is a cleared medical measurement of vitals. The Nanit’s version also requires buying the patterned garment, at roughly $30 a size as your baby grows.
The Nanit, if you want the sleep data. The Owlet is $299.99 and that is the end of it, with every feature included. Nanit lists the camera at $289.99 and keeps core monitoring free forever, but the analytics most buyers want run on Insights: a free Sleep plan for three months, then under $10 a month, or $120 a year for Memories, or $300 a year for Milestones. Over two years the Nanit can easily cost double the Owlet.
Plenty of people do, and Owlet sells the pairing itself as the Dream Duo, a sock-plus-camera bundle that is BabyGearLab’s top overall video monitor pick at 86, though at around $400 they call it spendy. Buying the Nanit and the Dream Sock separately is close to $600 for the first eighteen months. If you want both jobs covered, price the Dream Duo first rather than assuming two flagships is the answer.
For vitals, yes. The sock is the cleared part and works on its own with the base station and the app; the Dream Duo adds a stationary camera for about $100 more. If you already know you will want to see the crib at 2 a.m., buy the Duo once rather than adding a camera later. If the worry is oxygen and pulse, the sock alone answers it.
