What This Device Does Well

Provides reliable status reporting and user-facing alerts through the Arlo app when installed and enrolled correctly.

Before You Service or Replace One

  • Generation — Gen 1 vs Gen 2 vs 3rd gen — battery type and reset steps differ.
  • Hub online — hub must show connected in app before diagnosing sensor.
  • Range — distant devices may need Range Extender, not a new sensor.
  • Tamper — cover fully closed before declaring hardware fault.
  • Monitoring mode — Practice/disarmed modes affect whether alarms dispatch.

Use official kb.arlo.com support articles for reset procedures, battery types, LED patterns, and regional availability — Arlo updates app flows frequently.

Error Codes

Arlo products report faults through the Arlo app device status and device event history — not traditional numeric keypad codes like hardwired alarm panels.

How to read status

  1. Open Arlo appMenuAlarm (or device tile for cameras).
  2. Tap device status or the device — note Offline, Tampered, Low Battery, Open.
  3. Tap the fault for Arlo's suggested steps and linked support articles.
  4. For hub issues, check Home Security hub / SmartHub connectivity first — many "sensor offline" faults are mesh or hub internet issues.
