Axis Tailgate Detection Tested

By: Rob Kilpatrick, Published on Jan 04, 2019

Axis is aiming to tackle tailgating, one of access control's biggest issues, with the Tailgating Detector ACAP application. This camera app claims to do the job of much more expensive dedicated solutions at much lower cost.

We tested this new app in a simulated entrance scenario, testing with multiple subjects at various speeds, in varying light levels, with changing intervals and distance. In this report, we look at:

  • Axis setup guidelines
  • Use on typical surveillance fields of view
  • Pricing compared to dedicated sensors
  • Full light detection performance
  • Low light (<1 lux) detection performance
  • False alert sources
  • VMS integration
