Overview

This document details the installation of E2guardian (from now on E2G) on Ubuntu Xenial 16.04.

E2Guardian does not work standalone and required a proxy to be also installed. The most common proxy software is Squid, but Ubuntu also ships other two lightweight proxies that may be installed to work with E2G, tinyproxy and oops. Examples will be provided for both proxies in the guide.

Getting E2Guardian

# This script implements a motion capture surveillance cam for raspberry pi using picam

# It uses the "motion vectors" magnitude of the h264 hw-encoder to detect motion activity.
