PPE Expectations

Please note that, as PPE Detection is still in beta, some results may not always be perfect. We're actively working to improve its accuracy and capabilities, and user feedback is critical in this process.

Single Worker Entry 👷

To ensure optimal PPE Detection system performance, it is essential that only one worker enters the access control point at a time.


  • The system is designed to process and accurately identify individual workers. Multiple workers within the camera's field of view simultaneously may result in inaccurate or missed data points.

  • The client is responsible for maintaining traffic flow to ensure that the PPE Detection system can capture clear images of each worker independently.


False Positives ⛔

The system can only detect workers and PPE equipment, but it can:

  • miss an object (i.e. object is there but the system does not see it)

  • misidentify an object (i.e. object is not a PPE equipment, but the system thinks it is)

  • correctly identify an object, but the identification is misleading (e.g. working carrying a helmet but not wearing it)

It's important to understand that we cannot guarantee 100% accurate results in all situations. Factors like multiple workers, obstructions, and objects that mimic PPE Equipment can impact the system's performance.


The client is responsible for maintaining a clear view of the camera.

The PPE camera shall be free of stationary workers standing in front of the camera, and equipment left in the region of interest that could trigger the PPE system.

If false positive event volumes exceed normal patterns, we may consider your site a breach of the PPE Detection fair usage policy and suspend the processing of events.


Client-Provided Data 📅

To accurately assess the PPE system's performance, Evercam requires clients to choose one of the following options:


  • Provide Manual Logs: The client will provide manual logs or manifests of all workers entering the site for the first two weeks after installation. This data will be used to verify the accuracy of the PPE Detection system.


  • Report Individual Errors: If the client chooses not to provide Manual Logs, they will be solely responsible for identifying and reporting any missed worker events within the PPE Detection system. Without a benchmark like Manual Logs, neither Evercam nor the client can independently verify the system’s overall accuracy. Therefore, Evercam will rely exclusively on client-reported incidents to assess system performance.


Calibration Period 📉

A 14-day initial setup period is necessary for thorough system calibration and data refinement. During this time, client-provided data is crucial for identifying and correcting discrepancies.


Duplicate Entries and Other Reporting Considerations 📒

  • Our PPE system may generate duplicate entries within the reports. This can happen if the worker walks back and forth in front of the camera, where the “imaginary line” that detects the event is situated, as we use a line-crossing method.

  • To guarantee optimal system performance, we recommend a 14-day initial setup period to allow for thorough system calibration and data refinement.

  • While we strive for accuracy, it's essential to understand that these factors can influence the data produced by the PPE system.

  • If duplicate event volumes exceed normal patterns, we may consider your site a breach of the PPE Detection fair usage policy and suspend the processing of events.


Please note: Duplicate entries and other reporting nuances should not be considered system errors but rather expected outcomes in certain conditions.


Obstructions 🚧

Obstructions (people, machinery, etc.) that interfere with the camera’s field of view may result in missed events.


Non-Evercam Access Points 🚪

Entries through access points not covered by Evercam’s PPE System will not be logged.


Power Supply 🔌

Loss of power to the PPE camera system will result in unlogged events.


Install Conditions 🛠️

If the installation site conditions differ from the agreed-upon plan, including issues with the location or installation process, Evercam reserves the right to postpone installation. In this case, we will work with you to create a revised plan. A refund, minus site visit costs, will be issued.


Traffic Flow Compliance 🚦

Our PPE camera system is designed to optimally capture PPE information when workers approach the access point in a straight line, perpendicular to the camera's view. Any significant deviation from this path may result in missed captures and inaccurate reporting. To ensure accurate data collection, it is essential to maintain a consistent foot traffic flow pattern as outlined in the plan.


Deviations from the specified traffic flow can lead to reduced system performance and potential inaccuracies in the generated reports.


Weather Conditions 🌦️

Weather (rain, snow, fog) can reduce image clarity and result in unlogged events.
