What is a DSM alarm response log?
A driver status monitoring (DSM) camera watches the driver's face and raises an alarm when it sees signs of drowsiness or distraction. The alarm is only the start. What protects the driver is what your team does next, and how fast.
This log keeps that response on one row per alarm: who reached the driver, when, how, what the driver did, how long the rest was, what the supervisor decided, and whether the clip showed a real event. It turns a stream of alarms into a record you can review and improve.
Response rules you set
| Alarm type | Reach the driver within, first action |
|---|---|
| Eyes closed or drowsiness | 2 min, call and agree a stopexample |
| Yawning | 5 min, call and checkexample |
| Distraction or phone use | 15 min, clip review and coachingexample |
| Camera covered | 10 min, clear it at the next stopexample |
The minutes, rest times and repeat counts in the file are examples to show how the sheets work. No regulator or standard sets them for your fleet. Your safety policy does.
How the workbook checks each row
False alarms and the repeat count
Glare, sunglasses, headwear, the camera angle and normal head movement can all raise a DSM alarm with nothing wrong. That is why every row has a clip review. A false alarm does not count toward the stand-down review, and its cause belongs in a tuning log so the installer can fix the camera position or the setting.
Call hands-free or by radio. Never ask a driver to pick up a handheld phone while driving, least of all after a phone-use alarm.
What the log does not do
It does not judge whether a driver is fit for duty, and it does not track driving hours. It records the response to camera alarms. Which alarms your camera raises, their levels and their settings depend on the camera model and its configuration. Clips and this log hold personal data about drivers, so follow your driver notice and your retention rules.
