Risk level

Usually safe to check without specialist tools.

Urgency

Medium

Quick answer

If your Arlo camera is not detecting motion, check that it is in Arm Away or Arm Home (it does not record in Standby by default), that movement crosses side to side 5 to 20 feet away, that it is not looking through glass and that it has battery and connection.

Safety first

Stop and check this first

  • A factory reset removes the camera from your account and means setting it up again: keep it for when you have tried everything else.

Safe checks you can perform

  • Active mode and camera connection
  • Placement and glass
  • Motion detection test and notifications
  • Restart the camera and check Arlo's service

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Camera diagnosis by Arlo support
  • Do not attempt this professional task: Modes and alerts review with Arlo support

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Camera diagnosis by Arlo support

    What they doIf it still fails the motion detection test after correct placement, arming, a restart and a factory reset, Arlo support checks the camera.

    They must show youthe result of their detection test on your camera.

    In writingthe case number, the diagnosis and, if it is replaced, the reason.

  2. Modes and alerts review with Arlo support

    What they doIf the camera records but alerts do not arrive or go to the wrong place, Arlo support reviews the modes, rules and notifications on your account with you.

    They must show youwhich mode and rule each camera uses and who receives the alerts.

    In writingthe case number and the settings changed.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Active mode and camera connection

    No special tools

    Who:
    you, with the Arlo Secure app.
    How:
    check that the active mode is Arm Away or Arm Home, not Standby, and that the camera detects motion in that mode (Routines). Look at the battery in the lower right corner of the camera's device card and start a livestream to see whether it is online.
    Result that matters:
    confirming the camera is armed, charged and connected.
    If it was in Standby or low on battery:
    arm the mode or charge it and test again.
    If the livestream does not start:
    follow Arlo's camera offline guide.
    Evidence to keep:
    a screenshot of the active mode and the battery level.

    Evidence: Why is my Arlo camera not detecting motion?

  2. Placement and glass

    No special tools

    Who:
    you, no tools.
    How:
    aim the camera so people or cars cross its field of view side to side and 5 to 20 feet (1.5 to 6 meters) away, and do not place it behind a window, glass, plastic or a mirror, as Arlo recommends.
    Result that matters:
    the camera picking up motion when you walk across in front of it.
    If it detects after moving it:
    placement was the cause.
    If it still does not detect:
    check notifications and sensitivity.
    Evidence to keep:
    photos of the old and new placement.

    Evidence: Why is my Arlo camera not detecting motion?

  3. Motion detection test and notifications

    No special tools

    Who:
    you, with the Arlo Secure app.
    How:
    under Devices, open the camera settings, Default Mode Settings and Motion Detection Test, and follow the guidance to adjust sensitivity. Then under Routines pick the mode and the camera, turn on Motion Detection, Send Notification and Notify Everyone under Push Notification.
    Result that matters:
    the test detecting you walking past and the alert reaching you.
    If the alert arrives:
    sensitivity or notifications were the problem.
    If it does not detect in the test:
    restart the camera.
    Evidence to keep:
    the sensitivity chosen and a screenshot of the rule with notifications on.

    Evidence: Why is my Arlo camera not detecting motion?

  4. Restart the camera and check Arlo's service

    No special tools

    Who:
    you, no tools.
    How:
    with a removable battery, take it out for 30 seconds and put it back; if wired, unplug it for one minute; if it has no removable battery or connects directly to Wi-Fi, use Device Info and Restart in the app. Also check status.arlo.com for an outage.
    Result that matters:
    the camera detecting motion again after the restart.
    If it detects again:
    it was a one off lock up.
    If status.arlo.com shows an outage:
    wait for Arlo to fix it; if not, consider a factory reset.
    Evidence to keep:
    the restart time and a screenshot of status.arlo.com.

What it means

Arlo treats this symptom as a settings or placement issue before a fault. Its sensor picks up side to side movement better than movement towards the camera, and performs worse through glass, plastic or mirrors. The camera stops detecting with a very low battery or when offline, does not record in Standby by default, and may detect without alerting you if notifications are off or sensitivity is low. The symptom on its own never proves the camera is faulty.

Warnings and stop conditions

  • Loweditorial warning

    A factory reset removes the camera from your account and means setting it up again: keep it for when you have tried everything else.

Symptoms and causes

Probable causes · in order

  • Standby mode activeCommon

    Arlo says cameras do not record during Standby by default; Arm Away or Arm Home must be active for them to detect motion and record.

    Evidence: Why is my Arlo camera not detecting motion?

  • Placement or glass in frontCommon

    The sensor works best with side to side movement 5 to 20 feet (1.5 to 6 meters) away and loses performance when looking through glass, plastic or a mirror.

    Evidence: Why is my Arlo camera not detecting motion?

  • Low battery or camera offlinePossible

    The camera may stop detecting motion if the battery is too low or it is offline; starting a livestream confirms whether it is online.

    Evidence: Why is my Arlo camera not detecting motion?

  • Notifications off or low sensitivityPossible

    The camera may detect motion but not alert you, or not react at all, if push notifications are off in the rule or sensitivity is set too low.

    Evidence: Why is my Arlo camera not detecting motion?

  • Arlo service outageLess common

    Arlo asks you to check status.arlo.com to rule out an outage of its service before factory resetting the camera.
