Converged vs. Dedicated Networks For Surveillance

Author: Brian Rhodes, Published on Feb 11, 2015

Use the existing network or deploy a new one?

This is a critical choice in deploying video surveillance systems.

Though 'convergence' was a big theme of the past decade, deciding what to do has been much harder in practice.

In this guide, we break down the key factors in this decision, pro and cons, including:

  • IT vs Security Ownership
  • Existing Networks
  • Bandwidth
  • Network Quality
  • Technical Expertise
  • IT vs Security Ownership
  • Politics: Budget / Control / Avoiding Blame
  • Network Size
  • Expansion Difficulty
  • IP Address Conflict / IP Address Pool / Network Class
  • Security Concerns
  • Ongoing Maintenance Costs
