If your Arlo camera is not recording motion, the issue usually comes down to detection settings, arming modes, power, Wi-Fi, or video storage rules.
This guide explains the most common causes and the exact checks that usually restore motion recording quickly.
Why an Arlo camera may not record motion
Arlo cameras depend on a chain of settings and conditions before they save a motion clip.
If any part of that chain fails, the camera may still live stream, send alerts inconsistently, or appear online while missing recordings.
The most common reasons include:
- Motion detection is disabled or set too low
- The camera is in the wrong mode or not armed
- Activity zones, privacy zones, or geofencing are blocking detection
- Battery level, power source, or temperature is limiting performance
- Wi-Fi signal is weak or unstable
- Cloud recording, local storage, or subscription settings are not active
- Firmware, app, or sync issues are preventing recordings from saving
Check whether the camera is armed
Arlo cameras usually record motion only when the system is armed or a mode is active that allows recording.
If the system is set to disarmed, the camera may still be online but ignore motion events.
Open the Arlo app and review the current mode.
Confirm that the camera is included in a mode with an enabled motion rule.
If you use a custom mode, verify that the camera is not excluded from the rule list.
What to look for in mode settings
- The camera is assigned to the active mode
- Motion rules are turned on
- Recording is enabled for that rule
- The schedule, if used, matches the hours you expect
Verify motion detection sensitivity
Low motion sensitivity is one of the most common reasons an Arlo camera not recording motion issue appears.
If sensitivity is set too low, the camera may detect only large or close movement, missing people, vehicles, pets, or package deliveries.
Adjust the motion sensitivity for the specific camera and test it by walking through the detection area.
Increase the setting gradually rather than jumping straight to maximum, since very high sensitivity can cause frequent false recordings.
Test your detection area
- Walk directly across the camera’s field of view
- Repeat from different distances
- Test during daylight and after dark
- Check whether trees, traffic, or reflections trigger false events
Review activity zones and privacy settings
Activity zones help filter motion, but they can also block the exact area where motion occurs.
If a person, car, or pet moves outside the active zone, Arlo may not record it.
Privacy zones can also mask a section of the view and hide motion there entirely.
If motion recording stopped after you changed detection areas, temporarily disable zones and test again.
Then re-create the zone more carefully, making sure it covers the area where real motion occurs.
Confirm your recording and storage setup
Depending on the Arlo model and subscription plan, motion clips may be saved to Arlo Secure cloud storage or to local storage through a SmartHub or Base Station.
If the storage path is misconfigured, clips may detect motion but never appear where you expect.
Check these items:
- Your Arlo Secure subscription is active if cloud recording is required
- The camera is linked to the correct account
- Local storage is enabled if you use a SmartHub or Base Station
- The storage device has free space and is properly inserted
- The camera is connected to the base station if your model requires it
Some Arlo cameras can still send motion notifications even when recording storage is unavailable.
That makes it easy to think the camera is recording when it is only alerting.
Check battery level and power source
Low battery can reduce motion detection performance, shorten recording length, or cause the camera to behave inconsistently.
Wired cameras can also fail to record motion if the power adapter is loose, the outlet is unreliable, or power-saving settings are interfering.
If the camera runs on battery, recharge it fully and retest.
If it uses AC power, confirm the adapter and cable are secure.
For outdoor setups, inspect weatherproof connectors for corrosion or water intrusion.
Signs power may be the problem
- Recordings are shorter than usual
- Notifications arrive late or not at all
- The camera goes offline intermittently
- Live view works, but motion clips do not save
Test Wi-Fi and base station connection
A stable connection is essential for motion clips to upload and save.
Weak Wi-Fi can cause missed recordings, delayed alerts, or clips that never finish processing.
If your camera depends on a SmartHub or Base Station, a weak link to that hub can create the same symptoms.
Move the camera closer to the router temporarily and test motion again.
If the issue improves, the signal path is likely the cause.
You may need a Wi-Fi extender, better placement, or a different channel on your router.
For hub-based systems, verify that the base station shows normal status and that the camera is connected to it consistently.
Update the Arlo app, camera firmware, and device sync
Outdated firmware or an outdated app can cause motion rules to behave unexpectedly.
After an update, settings may also reset, sync incorrectly, or need to be re-saved before recording resumes.
Check for updates in the Arlo app and install them on both the camera system and your phone.
If recordings still fail, try removing and re-adding the camera to refresh the sync between the app and the device.
Inspect motion clip length and notification settings
Sometimes motion is being recorded, but the clip is so short or notifications are so limited that it appears as though nothing happened.
Arlo recording settings often include clip length, retrigger time, and notification preferences that affect how motion appears in the timeline.
Review whether:
- Clip duration is set appropriately
- Retrigger time is too long between events
- Notifications are turned off for that camera
- Sound or smart detection categories are filtered out
Rule out environmental causes
Motion detection depends on contrast, heat, distance, and camera angle.
Glass windows, direct sunlight, reflective surfaces, fog, rain, and moving shadows can all affect whether the camera records motion reliably.
If the camera is mounted too high or aimed too far away, the sensor may not detect movement well enough to trigger a clip.
Reposition the camera so motion crosses the frame from side to side, which usually produces better detection than movement directly toward the lens.
Run a quick reset and retest
If settings look correct but the Arlo camera is not recording motion, a simple reset often clears a temporary software issue.
Restart the camera, power cycle the router or base station, and relaunch the app.
After that, test with a controlled walk-through in front of the camera.
If the issue persists, remove the camera from the app and add it back again.
This can resolve sync problems that are not obvious in the interface.
When to contact Arlo support
If none of the checks restore motion recording, the camera may have a hardware issue, account problem, or base station fault that needs deeper troubleshooting.
Contact Arlo support if you see repeated offline behavior, failed firmware updates, or a camera that detects motion but never saves clips across multiple settings changes.
Have your model number, subscription status, firmware version, and a summary of the troubleshooting steps ready.
That information helps support isolate whether the problem is tied to the camera, the network, or the account.
