PPE Detection Cameras for Missing Safety Gear Review
A worker near machinery without visible required gear can need a supervisor’s attention. StreamVLM™ can surface the visible condition without deciding compliance from a frame alone.
The Visible Condition
Give the Operator a Frame to Review
The condition in scope is a person in a selected work area without the specified visible safety gear, such as a hard hat. It is a visible scene detail, not a diagnosis, a conclusion about intent, or an automatic decision.
In StreamVLM™, an authorized operator writes a prompt such as “Alert when a worker near machinery is not wearing a hard hat.” The model evaluates selected live frames against that prompt and sends a match, camera, location, and time into the IREX event workflow for human review.
StreamVLM™ runs on a GPU node in the customer instance. Each prompt has its own confidence threshold, alert cooldown, event type, and camera selection.

What the Operator Reviews
These illustrative frames show the kind of visible condition a prompt can surface. They are not real incidents, deployments, or proof of detection accuracy.

A reviewer checks the site’s PPE rule and current work status before contacting the safety team.
From Prompt to Action
A Review Workflow for This Condition
- 01
Define the Required Visible Gear
Write a concise prompt for a person in a selected work area without the specified visible safety gear, such as a hard hat, then select the cameras and times where the condition warrants attention.
- 02
Check Whether the Worker and Equipment Are Visible in the Task Context
Open the event with its camera, location, time, and available video context. Confirm what is visible before treating the match as actionable.
- 03
Send a Reviewable Event to the Responsible Supervisor
The authorized team applies the local procedure. StreamVLM supplies a review cue; it does not decide the response.
Limits to Test
Validate It on the Actual Cameras
- Scene Context
- The site must define which gear is required in each area and task.
- Camera Fit
- Hair, headwear, occlusion, and camera angle can hide or mimic a hard hat.
- Human Decision
- A frame does not determine training, authorization, injury risk, or regulatory compliance.
FAQ
Can this determine OSHA compliance?
No. The prompt can surface missing visible gear in a defined camera view. A qualified site process determines requirements and compliance.
Can StreamVLM confirm missing safety gear?
No. It reports a match to the visible condition in the prompt. An operator reviews the frame and local context before deciding what it means.
How should a team tune the prompt?
Start with representative cameras, define what makes a useful alert, then adjust the camera selection, confidence threshold, and alert cooldown during a camera-specific pilot.
Is there a published accuracy figure for this use case?
IREX does not publish a universal accuracy figure for this prompt. Image quality, camera angle, lighting, occlusion, and the local definition of a useful alert all affect results.
Pilot PPE Review in a Defined Work Zone
Begin with one work area, one visible item of gear, and a supervisor-led review process that reflects the site’s own safety rules.
