Problem Description

When your UniFi Protect UniFi Timeline Performance 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

  • Long delay while scrubbing
  • Playback jumps
  • UI stalls with high camera counts

Recognize these? Here's what usually causes it.

Common Causes

  • Storage throughput bottleneck
  • High concurrent stream load
  • Client decode limitations

Most fixes happen in the first 3 steps.

Warning

Do not diagnose timeline lag from one low-power client only.

Tools & Requirements

Step-by-Step Solution

1

Measure storage performance

Validate disk throughput and latency under playback load.

2

Limit concurrent heavy streams

Reduce simultaneous high-resolution playback sessions.

3

Compare client capability

Test timeline speed across different client devices.

Quick Solutions

Check storage health and IOPS
Reduce simultaneous high-bitrate playback
Test performance from stronger client hardware

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

Timeline performance is constrained by both server and client resources.

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
  • Storage throughput bottleneck
  • High concurrent stream load
  • Client decode limitations
