How an alert is handled

From alert to fix

Judge the alert, find the cause, fix it, then check the next week.

Why log false alerts?

Too many false alerts teach drivers and reviewers to ignore the system. Too few can mean real events are missed. A log shows which alert types, vehicles and conditions cause the false ones, so you tune with facts and not with guesses.

How to use the log

  1. Fill in Setup. Enter the first day of week 1 and edit the lists of alert types, causes and actions.
  2. Log each alert you review. Date, vehicle, alert type, then the result: confirmed, false alert or unsure.
  3. Pick a likely cause for every false alert, and the action you took.
  4. Open the Weekly view. See the false-alert rate per type and per week.
  5. Decide and record. Use Decisions for the next step, and Setting changes for every change you make.

How the false-alert rate works

The rate counts only alerts you could judge. Unsure alerts are shown separately so they do not hide in either group.

False-alert rate = false alerts / (confirmed + false alerts) Alerts per 100 km = reviewed alerts / km driven x 100Example: 4 false and 3 confirmed = 4 / 7 = 57%

Weeks with fewer reviewed alerts than the number in Setup are shown in gray. A rate based on a handful of alerts can swing a lot from week to week.

Fix the cause before the setting

Most false alerts have a physical cause: glare, glasses, a camera tilted down, a dirty lens, a loose mount or a passenger in view. The Causes sheet shows which cause explains the most false alerts, so you start there.

One change at a time

Lowering a sensitivity to cut false alerts can also hide real events. Fix the physical cause first. If you still change a setting, change one, write it in Setting changes, and compare the next week.

Reviewing video: privacy

Check your rules before you review driver video

Reviewing driver video can be regulated where you operate. Follow your company policy and local rules. This log stores references to clips, not video, and it is not legal advice. For the driver notice, see the in-cab camera notice template, which also needs legal review.

Limits of this log

It records and counts what you enter. It does not connect to a device, and it does not know which alerts your device reports. A sample of alerts can mislead if it is not typical, so write down how you chose it.

Know which alerts your Tracom device reports

Which DSM and ADAS alerts each Tracom model reports, and which settings you can change, come from the device documentation. Ask us before you start the log, so the alert types and setting names in the sheet match your device.

What counts as a false alert?

An alert where, after you watch the clip or check the data, the situation it describes did not happen. Decide the rule once and use it every week, with the same reviewer when you can.

How many alerts should I review?

In a small pilot, review all of them, or a fixed sample you write down. The sheet shows weeks with fewer reviewed alerts than the number in Setup in gray. 20 is a typical starting value, and you can change it.

Should I lower the sensitivity when false alerts are high?

Not first. Check the camera position, the lens, glasses, glare and the mount. Lowering a sensitivity can also hide real events. If you change a setting, change one at a time and log it.

Can I add my own alert types and causes?

Yes. Edit the lists in Setup. The drop-downs in the Event log and the tables in the other sheets follow them. Keep the three result words as they are.

Does the log work in Google Sheets?

Yes. Upload the .xlsx file to Google Drive and open it with Google Sheets. It also works in Excel and LibreOffice Calc.

What is Tracom's role here?

Tracom makes the devices. The log is a record-keeping tool. It does not say that any device reaches a given accuracy, and it does not name settings: use the names in your device documentation.
