PPE (Personal Protective Equipment)


The personal protective equipment, or PPE detection triggers an alarm if the person(s) detected are not wearing either a protective helmet, a visibility vest, or both - you may check the lack of either or both types of equipment to be detected.

NOTE: A single alarm tracking either vest or helmet (not both) takes up 17, 25 or 50 analysis slots by default (minimum 17), depending on the Analysis speed and maximum number of analysed people configured. Tracking both types of equipment with a single alarm requires 33, 50 or 100 slots (minimum 33). [Read below to learn more about Analysis speed].

  • Core technology: full body detection.
  • A camera with a minimum of 6 FPS is required!
  • Takes up a minimum of 17 analysis slots.
  • Compatible with fixed, PTZ, and thermal cameras.
  • Areas of interest can be defined.
  • Send data to third-party software.


  1. Choose PPE by clicking on its box. Fill in the form, as follows:
  2. Name: A readable name of this alarm. This name will appear in the Events view and in all notifications.
  3. Armed: The alarm can be deactivated here. Armed by default.
  4. Schedule (optional): You can associate one of your previously defined Schedules with this alarm.
  5. Add Camera: Select a camera from the list.

NOTE: Cameras below 6 FPS will not show up on the list of cameras for PPE!

Add Camera to Alarm
  • Draw Areas (ROI) (optional): Sometimes the alarm should be limited to a specific area of the video. If you would like to observe only a specific area, it can be determined here. Clicking this button makes the Camera Editor appear. Without ROI, the entire area will be observed.
Detection Size Settings
  • Set object size (optional): If you have a good idea of what pixel range the detected objects would fall into, you can customise the minimum and maximum height size of detections, in pixels, here. This would ensure that only objects that fit into that range would get detected, resulting in a further decrease in the number of false alarms.

    Move the the arrows by clicking and dragging them to help you determine the optimal values. Adjust the slider's endpoints on the bottom part of the screen to set the minimum / maximum values. Click Set sizes to save your changes, or Discard to cancel them.

    NOTE: Take care that any object below or above the set range will NOT be detected, possibly resulting in missing incidents. It is good practice to set the minimum size slightly below, and the maximum size slightly above the desired amount.

    For example: If using Ultinous AI Suite with a combination of radar and PTZ cameras, setting custom object sizes would result in detections only if the radar have detected movement - since setting the proper minimum size would rule out random noise causing false detections.

  • Sensitivity : The sensitivity of the detector can be fine tuned here. Lowering the sensitivity causes less false detections but decreases accuracy. Increasing it results in more alarms but may cause more false detections as well. The default sensitivity is Medium.

  • Selected personal protective equipment: Choose a one or both types of PPE to trigger alarms if the person(s) detected are not wearing them.

  1. Analysis speed : The maximum number of people analysed at the same time, at either Normal or Fast speed. Note that the faster the analysis speed and the more people it is run on, the more Analysis slots the alarm will use. The default settings are Fast, 15 people.

  2. Enable HTTP webhook (optional):

    Enables / disables event sending: Use this feature to send triggered events to a third-party software with an optional snapshot image of the incident attached. Sends a HTTP POST request to the URL set below, with a content type of application/json. Read on to learn about the schema formatting.

    The following information should be provided by the third-party software's administrator:

    • Target URL: The location of the API.
    • Header key and value: Key and value of custom HTTP header. Click the Add button to add more Keys. To delete a Key, press the Trash icon next to it.
    • Trust all certificates: If enabled, HTTPS certification errors will be ignored.

      NOTE: Custom CA certificates can be uploaded in the Trusted Certificates setting.

    • Enable snapshot attach: Off by default. If enabled, it fills in the snapshot field of the http message schema in base64 encoded format.Send Test Event: To test your integration, click the Send Test Event button once the HTTP webhook settings are set.
  3. Email notification configuration (optional):

    This feature allows you to send alarms via e-mail to designated recipients.

    IMPORTANT: Make sure that sender e-mail settings are already set! See the Sender configuration section for instructions.

    • Enable snapshot attach: Off by default, sends a snapshot of the event in .jpeg format. See the Snapshot part of the guide for its properties.
  4. Enable Genetec Security Center integration (optional): Ticking this button to set a custom event ID is one of the steps necessary for sending alarms to Genetec Security Center. See the Genetec integration guide for detailed instructions.

  5. Enable Central Station Monitoring support (optional): Tick this button to enable integration with Central Station Monitoring tools: SureView Response and Immix CS. Choose one from the dropdown menu.

    • Target email: The target e-mail, configured in Immix CS/SureView CS. See the E-mail settings for proper SMTP server configuration.
    • Enable snapshot attach: Off by default. If enabled, it fills in the snapshot field of the http message schema in base64 encoded format.

      Read on for a complete guide for SureView Response integration. For a complete guide on configuring Immix CS, see here.
