Angelcare AC337

Under-mattress movement sensor with video and two-way audio

Angelcare has been a trusted name in infant breathing monitoring since the 1990s. The AC337 combines an under-mattress movement sensor with a full video monitor — reassurance without attaching anything to your baby. At $130, it offers meaningful peace of mind at a fraction of the Owlet's cost, though it detects motion rather than oxygen levels.

✓ Pros

  • Under-mattress sensor pad detects breathing movement without touching baby
  • Sounds alarm if no movement detected for 20 seconds
  • Full video monitor with night vision and two-way audio included

✕ Cons

  • Movement sensor only — does not track heart rate or SpO2
  • Sensor pad must fit snugly; may not work with all crib mattresses
