Problem Description
When your UniFi Protect UniFi Smart Detection Regression 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
- No smart detections
- Only motion events remain
- Detection quality drops
Recognize these? Here's what usually causes it.
Common Causes
- Model/profile reset
- Detection settings changed
- Update regression
Most fixes happen in the first 3 steps.
Do not assume defaults persist after major version changes.
Tools & Requirements
Step-by-Step Solution
Check detection config
Confirm smart detection types remain enabled per camera.
Retest with known scenarios
Run controlled person/vehicle tests for baseline.
Patch strategy
Apply stable release path if regression is confirmed.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If the sensor still misses events after repositioning, check whether a scheduled 'home' or 'away' mode is overriding the sensitivity setting silently.
Post-update QA should include smart detection checks on representative cameras.
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.
- Model/profile reset
- Detection settings changed
- Update regression
Before you go — try one of these (they fix most cases).
