Axis Live Privacy Shield Analytics Tested

By: Sean Patton, Published on Jun 25, 2019

Privacy is becoming a bigger factor in video surveillance, driven both by increased public awareness and by GDPR.

Now, Axis has released Live Privacy Shield, a video analytic that Axis claims is "reliable and cost-effective" and is "the only edge-based solution that dependably masks moving people and objects in real time at up to full frame rate".

We tested Live Privacy Shield in multiple scenarios to see how it performs, including:

  • How well does it consistently mask people
  • Does it mask multiple subjects simultaneously
  • How it performs outside
  • How it performs in low light
  • How easy is it to configure
  • Pricing
  • Comparison to Genetec Privacy Protector
