PPE Mode

PPE mode is specialized for checking whether workers are wearing required protective equipment.

Best Use Cases​

  • Sites where helmet, mask, gloves, and similar compliance checks are required
  • Scenarios that must evaluate work context and equipment together


Example Inputs​

  • Detect workers soldering while not wearing a mask
  • Detect people not wearing a helmet and mask

In PPE mode, alert context is shown as PPE non-compliance detected.



Template Tips​

  • Create team-standard templates for required equipment sets (for example, helmet + mask).
  • If workflows differ by zone, separate templates by status to reduce false alarms.
  • When safety policy changes, update templates first and apply to cameras progressively.


Writing Tips​

PPE details usually focus on two fields.

  • status: target work condition or behavior
  • items: required equipment list

Operational tips:

  • Keep status to one clear work condition
  • Include only equipment that is truly required in the field
  • With multiple items, alert messages show missing items together

Examples:

  • PPE non-compliance detected: mask
  • PPE non-compliance detected: helmet, mask


Detection Quality Checkpoints​

  • Set detection target to person or worker so full-body boxes are captured reliably.
  • When many people appear in one frame, use camera angles where key workers are clearly visible.
  • If equipment appears visible but required body parts are often occluded, adjust camera angle/height first, then tune scenario text.

It is easier to diagnose false alarms when "work status" and "required items" are managed separately.



Advanced Settings​

PPE mode is typically used with single-frame analysis.

detection_mode : "ppe"
frame_mode     : "single"
