Use this guide when you can see the Samsara AI Multicam Hub and its LED.

For health status and definitions from the Samsara dashboard (Healthy, Needs Attention, Data Pending), see External Camera Device Health: Definitions and Troubleshooting (or the Camera Health report in your organization's help center). That report is based on connectivity and recording uptime over recent trip activity. This topic covers troubleshooting steps you can take at the device based on the LED you observe.

Supported devices: Samsara AI Multicam Hub (AIM4). AHD1 may have different LED behavior; use dashboard health status and your product documentation for AHD1.

Use the LED to Choose an Action

Check the AI Multicam Hub LED, then find the matching row in the table below. Perform the recommended action for that state.

LED state

What It Means

Recommended Action

gateway-health-indicator-healthy.png Solid green

Device is powered and recording. Connection to the Vehicle Gateway (VG) is good.

No action required. If the External Camera Device Health report still shows Needs Attention, check the health reason (e.g., low uptime, low connectivity, obstruction) and follow the report's recommended action.

Device is powered on, but no cameras are detected.

  1. Confirm each GX-12 camera cable is fully seated at the AI Multicam Hub and at the camera end.

  2. Verify cameras are connected to the correct hub ports and assigned in vehicle camera settings.

  3. Reseat camera connections and power-cycle the VG if the LED stays solid red.

  4. If you have a known-good camera and cable, connect it to isolate a faulty camera or cable.

  5. If solid red persists after you verify connections, contact Support.

Device is rebooting.

  1. Wait several minutes for the hub to finish rebooting.

  2. If the LED stays blinking red, disconnect and reconnect the cable to the VG, confirm the VG is powered, then wait again.

  3. If blinking red continues after a power cycle, contact Support.

Device is powered on, but not connected to a VG.

  1. Reseat the cable between the AI Multicam Hub and the VG.

  2. Confirm the VG has power and cellular connectivity; see Troubleshoot by VG LED State.

  3. Try a different USB port on the VG if available.

  4. Contact Support if solid yellow persists after you reseat connections and confirm VG power.

Device is powered on, connected to a VG and at least one camera is detected, but not recording (including when the vehicle is not on a trip).

  1. When the vehicle is not on a trip, the hub may not record. Start a test drive or trip to confirm recording begins.

  2. Verify the device is activated in the Samsara dashboard and assigned to the vehicle.

  3. Confirm the VG is connected to the cloud.

  4. If the LED does not turn solid green during an active trip, reseat the VG connection and contact Support.

No LED (off)

The hub may have no power, or it may not be connected to a VG. The AI Multicam Hub does not receive power from the VG, but it can receive a wake signal when the vehicle ignition is on.

  1. Check the cable connection between the AI Multicam Hub and the VG; reseat the connector firmly.

  2. Confirm the VG is powered (check the VG LED and vehicle ignition/power).

  3. Try a different USB port on the VG if available.

  4. If a known-good cable works on a different VG port but not on the first port, the VG USB port may be damaged; contact Support.

  5. If the device still has no LED after a known-good cable and a different VG port, the hub's USB input may be faulty. If you have a known-good AI Multicam Hub (for example, from another vehicle or a spare on hand), connect it with the same cable and VG port. If the second hub powers on, contact Support to replace the first hub. If the problem persists, contact Support.

[a] The yellow LED can sometimes appear amber or orange in color.

Note

Ongoing failure after you reseat connections, confirm VG power, and try another USB port may indicate a bad VG port or a faulty USB path on the AIM4, which is often resolved by replacing the affected hardware.

LED behavior and colors can vary by hardware revision. If your LED does not match the table or the issue continues after you follow the steps, see Report an Issue or contact Support with the exact LED pattern (solid or blinking, color) and the health status shown in the External Camera Device Health report.

Resolve Needs Attention in External Camera Device Health

When the report shows Needs Attention with a reason (for example, low uptime, low connectivity, media input not connected, or outward camera obstruction), use both:

  1. Check the AI Multicam Hub LED and follow the action for that state above.

  2. Perform the report's recommended action. For example, ensure the camera is properly connected and installed, remove obstructions from the outward-facing camera, or verify media inputs on the AI Multicam Hub.

After you take action, allow time for new trip activity so the report can recalculate health. If the status does not improve, contact Support and provide the health reason and the LED state you observed.
