People sensing and access control

Tailgate Detector

Reliable access control systems are crucial for buildings with secured areas, such as offices, airports, banks, university campuses, public transportation buildings, and so on. 

The Tailgate Detector is a solution for access-controlled entrances and is available in two varieties:

• TDflex^TM: tailgate detection at one-door access point (e.g. swinging door, sliding doors, virtual/no doors, optical or mechanical turnstiles)
• TDtrap^TM: tailgate detection at two-door transfer gates (e.g. mantraps and airlocks)

Based on 3D MLI Sensor^TM technology, the Tailgate Detector helps prevent piggybacking and tailgating, detects luggage left behind, and recognizes head-by-head or bi-directional situations.

Access control applications:

• Tailgate and piggyback detection in access-controlled buildings and university campuses
• Tailgate detection at entrances to restricted areas in office buildings
• Tailgate detection at border controls in airports
• Tailgate detection at entrances in banks
• Wrong-way detection at arrival gates in airports or at turnstiles in subways and train stations (see People Counter)
• High-throughput people counting at access-controlled entrances
