Density DPU

Density is people counting and tailgating detection system.

Customers can identify tailgating events and respond in real-time. When integrated with OnGuard, Density instantly and accurately identifies discrepancies between the number of person-entrances and the number of access-badge swipes. Tailgating incident alerts can be sent via SMS message and monitored on the Density Dashboard.

The Density interface has the following features:

  • Review historical tailgating events on a daily and weekly basis per reader.
  • Receive notification of tailgating events via SMS or Webhook integration.
  • Receive notification of tailgating events at OnGuard readers by a local audible alert.
  • View real-time people count analytics across all readers and filter by buildings, and broader campuses.
