Fixations
A fixation is a camera's detection of a vehicle: a snapshot, a timestamp, the camera, the recognised registration plate and a recognition confidence.
Open the page from Monitor → Fixations or at /fixations. The section
subtitle reads "Vehicle detections from cameras".
Filters
The filter bar at the top of the page:
| Filter | Purpose |
|---|---|
| Search plate or camera | Text search across both columns at once |
| From / To | A time range accurate to the minute |
| All cameras | Pick one or several cameras; the counter shows "3 of 12 cameras" |
| Confidence | Any confidence, ≥ 70%, ≥ 85%, ≥ 95% |
| Plate detected | Show only fixations where the plate could be read |
The counter beside the heading shows "1,248 fixations" — how many records match the current filters.
With no cameras selected you get No cameras; with no matches, "No fixations match your filters" plus the hint "Try a wider time range or clearing filters."
View modes
The switch on the right chooses the presentation:
- list view — compact rows: snapshot, time, camera, plate, confidence. Good for scanning large volumes.
- grid view — cards with large snapshots. Good when the image itself matters.
Records are sorted newest first and load as you scroll ("Loading more…").
What a record contains
| Field | Meaning |
|---|---|
| Snapshot | The frame at the moment of fixation |
| Time | Date and time |
| Camera | Which camera recorded it |
| License plate | The recognised plate, or Not detected |
| Vehicle | The matched vehicle, if one was found |
| Conf. | How confident the system is in the recognition |
Records whose date could not be determined are grouped under Unknown.

Reading the confidence figure
Confidence is an estimate of recognition quality, not a guarantee. A practical rule of thumb:
- ≥ 95% — usable without manual review;
- 85–95% — usually correct, but check the snapshot before anything with legal weight;
- 70–85% — needs a human to verify;
- < 70% — usually noise: a dirty plate, a bad angle, glare.
Vehicle confidence (the object was detected and classified) and plate confidence (the plate was read) are reported separately. The first can be high while the second is low — the vehicle is visible but its plate is unreadable.

Typical workflows
Find a vehicle by plate. Type the plate into the search field, widen the range with From / To, and drop the confidence filter if needed — partially recognised plates may not match an exact query.
Prepare a report for one observation point. Select a single camera, set a 24-hour range, switch on Plate detected and press Export CSV.
Assess recognition quality. Set the filter to Any confidence, switch to grid view and look through the low-confidence snapshots — the cause is usually visible: angle, glare or a dirty plate.
