By: IPVM Team, Published on Aug 21, 2018

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.
