Why Is Frigate Person Detection Missing at Night?
- Poor night exposure settings
- Insufficient IR illumination
- Model thresholds too strict
Problem Description
When your Frigate Frigate Night Detection 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
- Night misses
- Low-light false negatives
- Day detection normal
Recognize these? Here's what usually causes it.
Common Causes
- Poor night exposure settings
- Insufficient IR illumination
- Model thresholds too strict
Most fixes happen in the first 3 steps.
Do not over-lower thresholds globally; tune per camera/scene to limit false positives.
Tools & Requirements
Step-by-Step Solution
Review night video quality
Check exposure, shutter, and noise at night capture conditions.
Improve scene lighting
Add or optimize IR/flood coverage where feasible.
Retune detection settings
Adjust thresholds/zones and validate with repeated night tests.
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.
Night detection quality depends heavily on camera image quality, not only model settings.
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.
