Prevent tailgating with Vector 4D

Anti-tailgating with Vector 4D

Using the Vector 4D as a tailgate detector provides a significant increase in access control and security by detecting tailgating events in real-time.

A tailgating events occurs when an un-authorized person follows a valid card/badge holder through a controlled door into a building or area. Tailgaters may be doing so maliciously to bypass security measures or innocently, for example, by being letting somebody else in.

The Vector 4D uses proven people counting technology to accurately and anonymously count the number of people entering the secure area in real-time and raise alarms when tailgating events occurs.

Tailgating detection modes and uses

The Vector 4D supports several tailgating and security modes:

  • Standard tailgate detection mode
  • Wrong-way detection mode
  • 'Person in zone' detection mode

These modes can be used in:

  • Banks and office buildings
  • Defence and government buildings
  • Airports and transportation hubs
  • Schools, universities and colleges
  • Gyms, leisure facilities, hotels and accommodation blocks
  • Computer and data centres, cleanrooms and high security rooms

How the Vector 4D anti tailgating sensor works

The anti-tailgate detection functionality of the Vector 4D works in conjunction with an access control system to detect a person following a cardholder through a controlled entrance.

The number of valid card swipes is compared to the real-time count of the number of people entering. A difference in these counts indicates a tailgating event and generates an alarm signal.

This tailgating alarm can be used to trigger an appropriate response:

  • Sound a local buzzer or alarm at the door to allow local staff to challenge the person tailgating.
  • Record the tailgate alarm to allow daily/weekly event logs to be generated.
  • Trigger live CCTV images to be displayed or recorded.
  • Automatically lock a second subsequent door/gate.
