How does AI PPE monitoring work on construction sites?

Short answer

AI PPE monitoring analyses site camera footage with computer vision to check whether workers are wearing the required protective equipment, such as hard hats and high-visibility vests. SmartSites records each check with an annotated snapshot and its location, and can also alert on restricted or crowded zones. It works with existing IP cameras through a small on-site box.

How it works

  1. Connect a SmartCam or your existing IP cameras and recorders through the on-site box.
  2. Clips are sent over an outbound encrypted connection; each camera has its own key.
  3. Computer vision checks each clip for the required PPE, such as hard hats and vests.
  4. Missing PPE and restricted-zone entries create alerts with an annotated snapshot and a location.
  5. Trends show compliance over time by area, so safety teams can see where issues repeat.

Test before you install

You can test the safety model on your own photo or clip before installing anything, to see how it handles your site's lighting, angles and equipment.

More than PPE from the same camera

The same footage is also analysed for how much of the observed time is active work, for people counts, and for stockpile volumes.

Privacy by default

Productivity analysis is anonymous and zone-level, never per worker, and safety footage is deleted automatically after 30 days unless you choose otherwise.
