Video Privacy Mask Tutorial

Author: Ethan Ace, Published on Feb 27, 2018

Privacy has historically been hotly debated in the surveillance industry, especially in public surveillance systems where cameras may be located in residential areas. This is becoming even a greater concern as the EU implements the General Data Protection Regulation (GDPR)

Privacy masks are a feature widely supported in cameras and some VMSes that aims to improve privacy. In this tutorial, we explain:

  • Opaque vs translucent pixelated masks
  • Shapes of masks allowed
  • PTZ camera masking
  • Static vs dynamic masks
  • Camera vs server side masks
  • Analytics for privacy masking
  • Removable camera masks
  • Risks of blocking usable video
  • Bandwidth reduction
