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