How to Fix Frigate Zone Filters Missing Expected Events
- Zone geometry too restrictive
- Object class filter mismatch
- Threshold settings too strict
Problem Description
When your Frigate Frigate Zone Filter Tuning 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
- Events visible but not flagged
- Objects cross scene but no alert
- Works outside filtered zones
Recognize these? Here's what usually causes it.
Common Causes
- Zone geometry too restrictive
- Object class filter mismatch
- Threshold settings too strict
Most fixes happen in the first 3 steps.
Over-tight zones can silently suppress high-value events.
Tools & Requirements
Step-by-Step Solution
Replay missed event path
Map actual movement path against configured zones.
Adjust zone boundaries
Expand or reshape zones to include true target trajectories.
Revalidate filters
Test expected class/threshold combinations with controlled motion.
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.
Zone tuning should be based on recorded real-world paths, not static assumptions.
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.

- Object class filter mismatch
