eufy Baby Monitor E21 vs Nanit Pro

The short answer

These two represent the big split in video monitors. The eufy E21 is a hybrid: a 4K camera with its own 5-inch parent unit, an app when you want it and no subscription. The Nanit Pro is an app-only overhead camera built around sleep analytics and breathing motion monitoring, with the best of that data behind Insights plans once the free trial ends.

On picture, the eufy wins on raw sharpness, and its physical Wi-Fi switch gives it the privacy edge. On insight, nothing touches the Nanit: if you want to know how your baby slept last night and how that's trending, it's in a different league. The Nanit's running costs add up once the trial is over, though, while the eufy costs nothing after purchase apart from a microSD card.

My call: the eufy E21 for most families. Choose the Nanit Pro only if you know you'll use the sleep data and you're happy for your phone to be the monitor.
