AI PPE detection camera

A supervisor cannot watch every site entrance at once. AI PPE detection can flag supported conditions such as a missing hard hat or high-visibility vest, giving the team another way to review equipment use. It supports supervision rather than replacing it.

AI-generated illustration of ppe detection. The scene and overlays explain the concept; they are not a PGAK screenshot or measured result.

Seen on a real line

Recorded by PGAK on an existing line camera. It shows the function running under the conditions stated beside the clip; it is not a measured accuracy figure. The illustration above is a drawing of the idea.

Bare hands flagged on an assembly line14s · no soundFrom a vehicle-chassis line, playing at about twice real speed. The box is drawn on the hand, not the person, and the number beside each label is the model’s confidence in that detection. The figures change from frame to frame, and the low ones are left in deliberately, because that is exactly the sort of detection a supervisor should be checking rather than a system acting on by itself.Conditions: Recorded on an existing overhead line camera; the clip’s burned-in overlay reads 01-04-2023, 16:57. Gloves are one PPE class; which classes apply to your site is confirmed before anything is quoted. The clip carries no audio track.

How it works

Detect supported conditions such as missing hard hats or high-visibility clothing.

Where it could help your business

Help supervisors review PPE use at construction entry points.

Ask exactly which equipment types the system detects. Test the helmets, vests, uniforms and working positions used on your site. A clear checkpoint view may be more useful than a distant camera covering an entire construction area.

What your camera setup needs

Confirm the exact PPE classes supported. Site testing and human safety supervision remain necessary.

Does PPE detection prove that a site is compliant?

No. It checks supported visible conditions within a camera view. Equipment quality, correct use and wider safety obligations require separate assessment.

Check it on your own site

Bring a camera model list and explain the event you want to find or detect. We can use that to scope a compatibility assessment. Ask for a written proposal naming the supported functions, processing hardware, licences and pilot checks before agreeing to an installation.

PPE detection: estimate it for your site

Use your own measurements. The result is the staff time released, shown separately from any cash, using the formula below. It runs in your browser and nothing is sent anywhere.

Fields start empty. A blank is “not entered”, not zero; type 0 where 0 is true.

Money (optional)

Salary plus benefits and overheads, per working hour. Needed only if you enter a realisation above 0%.

0% unless you can name the mechanism — overtime that stops, a post not refilled, a contract reduced.

Only from your own records. May be negative.

Licences, support, connectivity. Enter 0 if there is none.

Hardware, installation, commissioning. Enter 0 if there is none.

Enter every amount on the same basis — all including GST or all excluding it. Nothing here adds or removes tax. Values are nominal rupees, not discounted.

Result

Enter your own figures, or load the worked example, to see the result.

How it is calculated

hours = samples × (old − new) ÷ 60 − validation hours

Worked example (illustrative inputs)

300 samples; 2 old; 0.5 new; 2 validation hours.

staff time released: 5.5 hours a month.

Formula version 1.0.0.

What this does not tell you

  • Hours released are capacity, not cash. They become cash only through a mechanism you state — overtime that stops, a post that is not refilled — entered as the realisation fraction.
  • The 'after' values are your assumptions or pilot measurements. PGAK publishes no effectiveness figure for this feature.
  • This estimates review effort only. It does not value injuries or lives, does not promise that any incident is prevented, and is not a replacement for certified alarms, required guards or supervision.

Evidence status: Limited public demonstration; no measured savings verified.

Your result stays on this page either way. If you want it checked against your cameras and quotation, leave a number; mention the figures on the call. Nothing you typed into the calculator is sent with this form.
