All Arlo cameras can detect motion. However, the motion detection feature works differently, depending on which camera you have.
Arlo wire-free cameras and Video Doorbell
Arlo Ultra, Pro 3, Pro 3 Floodlight Camera, Essential wire-free, Video Doorbell, Pro 2, Pro, Go, and Wire-Free trigger when the infrared technology detects an object that is warmer than the surrounding environment. The motion sensor is more sensitive to side-to-side movement across its field of view than to movement directly toward or away from the camera. The motion sensitivity settings range from one (low sensitivity) to 100 (high sensitivity).
Arlo Q Plus, Q, and Baby
Arlo Q Plus, Q, and Baby analyze changes in video frames to trigger motion detection alerts and recordings. The motion sensitivity settings range from one (low sensitivity) to nine (high sensitivity). In addition, you can create up to three activity zones. Activity zones allow you to focus the camera's motion detection on a specific area to trigger snapshots or video recording.
