If the status reads Not connected, the issue is the device rather than the cameras. Check the device's power and network. If a router or switch was replaced recently, confirm the device is still on the same network.

Unless the camera was switched off, a tile showing a camera icon without video means the device could not reach that camera. Check the camera's power and network, and whether its address or password changed.

1. Confirm monitoring is not stopped.
2. Confirm the alert switch is on.
3. Check whether a message is shown under the alert. See Disabling and Deleting Alerts.
4. Confirm the alert's hours include the current time.
5. For a face alert, confirm face recognition is on and a face is registered.
6. Confirm the Grablo app is installed on the phone and signed in with the same account.
7. Confirm the phone allows notifications from the app.

In Settings > Accuracy / speed, set Detection delay to Only when certain and Person threshold to Strict. In busy locations, narrowing the alert's hours is also effective.

Set Detection delay to Fast and Person threshold to Loose. When people are far away or backlit, adjusting the camera's angle and position is more effective than any setting.

Set Face threshold to Strict and register additional photos of that person.

This is expected immediately after saving settings, because the device restarts. If it recurs continuously, check the network bandwidth and the camera's stream settings.

Confirm monitoring is not stopped and the camera is not switched off. If only older recordings are missing, they were deleted by the storage period.

Search covers only recordings indexed at save time, and face search works only on recordings saved after face recognition was enabled. See Four Search Methods.

If Could not save is shown, retry after a moment. If a message says some changes were not applied, save again.
