Dynamic vs Static IP Addresses Tutorial

Published Apr 16, 2020 16:00 PM

While many cameras default to DHCP out of the box, that does not mean you should use it. This may seem basic for some, but those new to the industry may not know there are other options.

Inside, we cover the following topics and their impact on surveillance/security networks:

  • Static addressing
  • Dynamic addressing
  • Address Reservations
  • Advantages
  • Disadvantages
  • Potential issues of each
  • Public vs. private IP address impact
  • IPVM recommendations

For basics on IP addressing cameras, see our Network Addressing for Video Surveillance Guide.
