⚙️ Configuration

Basic Parameters

Parameter	Description	Default
`Enable workplace monitor`	Enable presence tracking	Off
`Use object detector`	Use detection model for person detection	On
`Use pose detector`	Use pose detection for accuracy	Off
`Target object`	Object class to track	person
`Require initial presence`	Require initial presence before tracking	On

Timeouts

Parameter	Description	Default
`Source grace (sec)`	Grace period after detection loss	1.5 sec
`Absence alert after (sec)`	Time absent before alert triggers	30 sec
`Presence confirm (sec)`	Time present to confirm return	5 sec

For break monitoring, set Absence alert after = 900 (15 minutes). Alert triggers only when employee is absent for more than 15 minutes.

📍 Workplace Zones

A workplace is a zone on the image. The operator must be inside the zone for presence/absence tracking.

Zone Management

Button	Action
`DRAW WORK ZONE`	Start drawing workplace zone
`CLOSE WORK ZONE`	Finish and save zone
`REMOVE LAST WORK ZONE`	Remove last zone
`RESET WORK ZONES`	Remove all workplace zones

Draw zones precisely around the workstation boundaries. Multiple zones are supported — each zone tracks separately with its own incidents.

📲 Telegram Notifications

When workplace monitoring is enabled, notifications are automatically sent:

🚨 #workplace_absence
Camera: Office entrance — operator left workstation

✓ #workplace_return
Camera: Office entrance — operator returned (absent 5 min 23 sec)

Duplicate Prevention

Duplicate alerts for the same incident are blocked by incident_id. Each zone maintains its own incident counter.
