IP Vs Analog Intercoms

Author: Brian Rhodes, Published on Jun 20, 2016

Intercoms, even within physical security, are a niche.

But Axis' acquisition of intercom manufacturer 2N represents a significant investment into this market segment.

Indeed, Axis is emphasizing the value of IP intercoms both for doing the deal and in focusing future efforts.

But what really is the difference between IP and analog intercoms? Is there something like a 'MP' intercom? Where is each type better or worse?

In this guide, we answer these questions.

Key Comparisons

While performance of intercoms and intercom systems may be basic, there are some some big gaps between the two major intercom technology types. The notable differences:

  • Pricing for Intercoms
  • Hub and Spoke vs Mesh
  • No Central Exchanges Needed With IP
  • System Integrations Easier with IP
  • IP Based Video Quality Better

We examine these points in detail below.
