Network Monitoring / SNMP for Video Surveillance Guide

Author: Ethan Ace, Published on Feb 02, 2015

Surveillance systems typically rely on the the VMS to report issues, but this most often just means knowing a camera is "down" with no warning or detailed information.

Network monitoring systems can give users more insight into their network, from the camera to the switch to the VMS server, but are seen as too complex or expensive to be used in simple surveillance systems. 

However, significant practical benefits can be gained by understanding these monitoring platforms, with free software available, and minimal setup time.

In this guide, we take a look at network monitoring specific to surveillance, explain the basics and software available, and give real practical examples of its use.

Topics Covered

In this guide, we cover these topics:

  • What is SNMP?
  • What are traps and requests?
  • How do I monitor this data?
  • What monitoring do cameras, servers, and other devices support?
  • What is a MIB and how do I use them?
  • What practical surveillance applications are there?
