Absence from post
Reports when a post stays unattended for the set time; also records the worker’s return.
Absence from post analytics continuously monitors whether at least one person is present at a post. If the workstation stays empty for the time you set, ProVife creates an event. When the worker returns, a second event is produced that states how long the post was empty, in minutes and seconds. This way, not only the absence but also its duration is on record. It is suited to posts that must be staffed at all times, such as security booths, control rooms, checkouts, reception desks and critical machine stations. Analytics hours are set to match working hours.
How it works
Draw the post as an area covering where the worker sits or stands.
Enter the vacancy time in seconds; the default is five minutes.
Set analytics hours to match shifts and working hours.
ProVife stores the last moment a person was seen in the area and creates a vacancy event when the time is up.
When the worker returns, a return event is recorded along with how long the post was empty.

Camera placement
