VLANs for Video Surveillance Tutorial

Author: John Scanlan, Published on Sep 26, 2016

Many people confidently say to 'use VLANs' as an answer to IP video networking problems and as a way to signal expertise.

But how should VLANs be used? What benefits do they really deliver or not?

In the note, we examine:

  • Segmentation of applications across VLANs
  • Untagged vs tagged VLANs
  • Static vs dynamic VLANs
  • VLANs for uplinks
  • Bandwidth and VLANs
  • QoS and VLANs
  • Common applications of VLANs
