How TDexpress works:

• The 3D sensor that defines the TDexpress sensing technology captures real-time topographic images of the surveyed area

• The sensor is sensitive and accurate enough to calculate the exact number of people transiting through the gates (no face recognition, fully respecting privacy)

• When a tailgating/ piggybacking event is detected in either in or out directions (discrepancy between activated security identification and the actual number of people going through the gates), the sensing system triggers an alarm

• This tailgating alarm can be set to provide customized actions: automatically lock the gates, alert the personal via a specific sound, etc.

• Flexible implementation of min/max occupancy thresholds and alerts
