Recorder health

NVR health: is the recorder still recording?

A live picture does not prove that footage is being kept. Recorder Health reports a full disk, a failed disk, a disk that is not formatted, and recording that has stopped, for cameras on that plan.

FOUR RECORDER CHECKS

  • Disk full
  • Disk error
  • Disk not formatted
  • Recording stopped

Recorder health, not the picture

Four recorder checks

These checks come from the recorder, not from looking at the camera picture. Hikvision, Prama, Dahua, and CP Plus are supported. Other brands can be saved on the camera and are shown as not checked. One recorder is reported once, even when several cameras use it.

CHECK 01

Disk full

The recorder reports that the disk has no free space left. New footage is no longer being kept, even though the cameras may still show a live picture.

CHECK 02

Disk error

The disk is offline, reporting an error, or failing a health status. The recorder is no longer a reliable place to keep footage.

CHECK 03

Disk not formatted

A new or replaced disk that was never formatted cannot store video. The check names that state instead of waiting for someone to notice empty playback.

CHECK 04

Recording stopped

Recording is off on the recorder, so playback for that period will be empty. One idle camera is not an alert. The live view can still look healthy.

How often it is checked

The plan turns Recorder Health on or off. The organisation chooses how often to check, usually every 15 minutes, and not more often than every 5 minutes. One setting covers every recorder for that organisation.

Reports

Filter by date, location, and group, and download a CSV. A period with no fault, a fault that is still open, a recovery, and a recorder that was not checked are labelled separately. The owner sees the selected business only.

Status app

NVR Health appears when this login has a camera on a Recorder Health plan. A new fault and a recovery are notified on the same timetable as a camera-down alert.

Parameter What the owner is told Supported recorders
Disk full The disk has no room for new footage. Hikvision, Prama Hikvision, Dahua, CP Plus
Disk error The disk is failed, offline, or unhealthy. Hikvision, Prama Hikvision, Dahua, CP Plus
Disk not formatted The disk cannot store video yet. Hikvision, Prama Hikvision, Dahua, CP Plus
Recording stopped Recording is off on the recorder. One idle camera is not an alert. Hikvision, Prama Hikvision, Dahua, CP Plus

Uniview, Matrix, Axis, Bosch, Hanwha, Sparsh, and Trueview can be saved as the camera brand. They are shown as not checked. A recorder whose cameras do not share one supported brand is also shown as not checked.

Does a live view mean the recorder is recording?

No. The live picture can look normal while the disk is full, the disk has failed, or recording is switched off. Recorder Health is the check for that.

What happens when the fault clears?

The open fault closes and the report shows it as recovered. The Status app is notified on the camera-down timetable. The history keeps the fault and the recovery.
