Official information
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.

- Confirm Arlo app on latest version; owner account available for setup.
- Plan device name and room in app for service clarity.
- For monitored locations: verify alarm permit and emergency contact list current.
- Have replacement batteries or transformer spec confirmed before truck roll.
Typical install sequence
- Set up Home Security hub / SmartHub first if this is an alarm Z-Wave device.
- Mount hardware per official template — drill, adhesive, or screw as specified.
- Insert battery / connect power; remove pull tab if present.
- Add Device in Arlo app; scan QR or follow in-app prompts.
- Complete placement test (motion, contact gap, outdoor comm test) at final location.
- Arm/disarm test or Live View test; confirm events in app history.
