Problem Description
When your UniFi Protect UniFi Timeline Gaps isn't working as expected, it usually traces back to one of a small number of causes — this guide covers them in order, starting with the most likely.
Symptoms
- Gaps in timeline
- Detections without clips
- Short missing windows
Recognize these? Here's what usually causes it.
Common Causes
- Recording policy mismatch
- Storage stress
- Indexing/recovery lag
Most fixes happen in the first 3 steps.
Do not tune retention aggressively without checking drive throughput impact.
Tools & Requirements
Step-by-Step Solution
Review camera policies
Verify each camera still uses intended always/event recording mode.
Inspect storage load
Check disk utilization and health for write bottlenecks.
Validate after reindex
Retest timeline once indexing/recovery tasks complete.
Quick Solutions
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.
Use controlled motion tests after policy changes to validate timeline integrity.
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.

- Storage stress
