Gocam - IP camera alert tool written in Go

Simple script to get an image from the IP camera every x seconds, calculate the unique hash with the perception hashing algorithm and compare it with the previous capture. When the configured treshold is reached, it will trigger an action.

Currently supported alerts/actions:

• Write a line to a log file
• Use ImageMagick's 'compare' tool to create a difference image from the snapshots
• Telegram alert

Features

• Send Telegram alert when movement is detected (after 5 cycles, eg 5 x 5 seconds if the interval is 5s)
• Create compare image when movement is detected
• Simple web interface to see the camera snapshots for the alerts

Installation

• Run make
• The binary is compiled in the dist folder
