Camera Edge Storage / Recording Tutorial 2015

Author: John Honovich, Published on Jun 29, 2015

~70% of IP cameras allow storing video onboard, at the 'edge', typically through the use of SD cards.

The big question is whether and when it makes sense to use edge storage / recording inside the IP camera.

In this tutorial, we teach:

  • Edge compared to centralized and edge site storage
  • The 3 most common edge applications explained - server elimination, network load reduction and recording redundancy
  • Camera support and limitations
  • Third Party Compatability and ONVIF Profile G
  • Storage Reliability
  • Direct to NAS Alternative
  • Stealing Storage
  • The Business Case for Edge Storage
  • Future of Edge Storage
