Problem Description

Your Lorex security camera recordings are missing or showing as corrupt during playback. Check the recording schedule and channel assignment first — each camera channel must be configured for continuous or motion recording in the NVR/DVR settings. Missing recordings may mean the schedule doesn't cover that time, or the hard drive is failing.

Why This Happens in Real Homes

Missing or corrupt Lorex recordings come down to two areas: whether the system was set to record that footage in the first place, and whether the hard drive is healthy enough to store and replay it. Start with the schedule and mode, because each camera channel records on its own schedule and mode (continuous or motion), and footage that was never scheduled simply won't exist - which looks identical to 'missing' recordings. Confirm the channel is enabled and its schedule covers the times you're looking for, and understand your retention: with overwrite on, the NVR recycles the oldest footage once the drive fills, so old clips disappearing is normal capacity behavior, not a fault.

Corruption specifically points at the drive or power. Surveillance hard drives wear out, and a drive developing bad sectors or throwing SMART errors produces exactly these symptoms - stuttering playback, unreadable segments, and gaps - and needs replacing with a surveillance-grade drive rated for continuous recording. Power interruptions are the other corruption source: an NVR losing power mid-write can leave damaged segments, which a UPS prevents. Run the NVR's disk check to assess drive health, make sure the drive was properly initialized for the system, and keep the firmware current, since firmware bugs can also cause recording gaps.

Symptoms

  • Recordings missing from the timeline
  • Playback shows corrupt or unreadable segments
  • Gaps in footage at certain times
  • Some channels have footage, others don't
  • Recording stopped after working before
  • Playback stutters or freezes
  • Older footage gone sooner than expected
  • NVR reports a disk error

Recognize these? Here's what usually causes it.

Common Causes

  • Recording schedule doesn't cover that time
  • Channel not set to record (mode not enabled)
  • Hard drive failing (bad sectors, SMART errors)
  • Overwrite settings recycling footage early
  • HDD full with overwrite off
  • Drive not initialized/formatted for the NVR
  • Power interruptions corrupting segments
  • Firmware issue on the NVR

Most fixes happen in the first 3 steps.

Warning

Export important footage before it gets overwritten.

Step-by-Step Solution

1

Check recording schedule and channel assignment first

Verify each camera channel has an active recording policy and correct timeline window, because missing schedule blocks are a common reason footage appears absent.

2

Inspect storage health and disk error indicators

Review NVR or storage diagnostics for bad sectors, disk full conditions, or write failures, since corrupted media layers frequently cause unreadable clips.

3

Validate network stability between camera and recorder

Check packet loss and link drops on wired or wireless camera paths, because unstable transport can create timeline gaps and partially written files.

4

Reboot recorder and apply latest firmware updates

Restart the recorder and update firmware to current release, because recording-index corruption often clears after controlled restart on stable software.

5

Run short continuous test and verify playback integrity

Record a known ten-minute window and confirm clean playback from start to end, so you can isolate whether corruption is ongoing or historical.

Quick Solutions

Verify the recording schedule covers the missing times
Enable the correct recording mode for each channel
Check HDD health; replace a failing surveillance drive
Review overwrite settings and retention expectations
Enable overwrite (or expand storage) if the drive is full
Initialize/format the drive for the NVR if needed
Use a UPS to prevent power-loss corruption
Update the NVR firmware

Still having issues? This is usually the deeper cause below.

If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.

Pro Tip

Set up activity zones to monitor only the areas that matter like your front porch and driveway and exclude the street. This dramatically reduces false alerts while ensuring you never miss an actual event at your property.

Real-World Insight

This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.

What Usually Goes Wrong
  • Recording schedule doesn't cover that time
  • Channel not set to record (mode not enabled)
  • Hard drive failing (bad sectors, SMART errors)
  • Overwrite settings recycling footage early
  • HDD full with overwrite off
