Arlo All-in-One Sensor vs Eufy Motion Sensor

The Arlo All-in-One Sensor comes out ahead overall, winning on price, integrations and its broader sensor set. The Eufy Motion Sensor wins on owner rating, connectivity and detection range.

Sensing scope and voice assistant support. The Arlo All-in-One Sensor adds ambient light and temperature to motion detection and works with Google Home and Alexa, while the Eufy Motion Sensor is motion-only and has no Alexa, Google Home, Apple HomeKit or Matter support at all, just the eufy app plus Home Assistant.

Yes. The Eufy Motion Sensor needs a eufy HomeBase to report motion or sound any alert, and the Arlo All-in-One Sensor needs a compatible Arlo Security System hub or keypad, since neither has a standalone radio that reaches your router directly.

The Eufy Motion Sensor is rated for a longer detection distance on paper, though real-world range for battery PIR sensors like this typically runs shorter than the spec sheet suggests.

Buyers who want one affordable sensor tracking motion, light and temperature, with voice control through Google Home or Alexa.

Households already running a eufy HomeBase who want a dependable, long-battery-life motion trigger for eufy cameras and don't need broader voice assistant integration.
