QoS for Video Surveillance

Author: IPVM Team, Published on Dec 29, 2017

Along with VLANs, QoS is one of the most misunderstood topics in IP surveillance networks. Many purported "experts" claim it is required in any and all surveillance systems, but little clear guidance is given about why, leaving those new to the field confused. In this note, we cover the basics of QoS, what it is, how it is applied, and when it should be used.

Inside we explain:

  • What is Quality of Service
  • How Quality of Service is Applied
  • Limitations
  • Practical Uses
  • Setting up QoS
  • Quiz Yourself: 5 Question Quiz to measure your knowledge on QoS for Surveillance

This is one of many tutorials on networking for surveillance. Others include: Wireless Networking for Video Surveillance, Network Addressing for Video Surveillance, Bandwidth Guide for Video Surveillance, Remote Network Access for Video Surveillance, Network Monitoring / SNMP for Video Surveillance, and more.
