The Circle 2 camera is equipped with two key sensors; a video sensor and a low power motion sensor. Depending on the attached mount and camera settings, your camera uses one of these sensors to determine when and how to record events.

Wired, Window or Plug Mount Cameras
While attached to the Wired, Window or Plug Mount (direct-to-power), Circle 2 uses the video sensor to constantly analyze its field of view for motion. As soon as it detects relevant motion, the camera starts recording. The camera stops recording once motion is no longer detected. If motion is detected shortly after a brief period of inactivity, the system may append this activity to the same event bubble.

Wire-Free Cameras
While attached to a battery and in battery optimization mode, Circle 2 operates differently. The camera uses the low power motion sensor (a passive infrared sensor or PIR sensor) to detect activity in its field of view. Similar sensors are used on motion-activated night lights.

Using the low power motion sensor allows the camera to keep the video sensor, which may drain the battery, in sleep mode. When the low power sensor detects motion, the video sensor wakes up, which triggers recording. Recordings occur in 10, 30 or 60-second intervals before the video sensor goes back to the sleep mode.

If the camera is already awake (e.g. if you are watching the live stream), the camera will automatically use the video sensor to determine relevant motion and manage recordings without needing to use the low power sensor first.

You can adjust the sensitivity of the low power motion sensor to ensure you are capturing the moments that are relevant to you. From the Settings menu, tap More Settings to edit the Motion Sensitivity.

NOTE: If you're using the Circle 2 Wired camera or placing the camera on the Window and Plug mounts, motion detection will work through glass. If you're using the Wire-Free camera, it relies on a low-power sensor for motion detection that doesn't work through glass.

Recordings in the Logi Circle app
The blue bubbles mean high activity level and the gray bubbles mean low activity level. If you don’t see any blue or gray activity bubbles, check that “All Activity” is selected in your Event Filter menu (to access the Event Filter menu, tap the three bubbles on the top left of your Live View). Also, make sure Privacy Mode is disenabled since Circle 2 does not record any footage even if it detects motion when Privacy Mode is enabled.
