Description	A way to remotely capture pictures with a DSLR.
Author(s)	German

It all started a few month ago with the idea of improving an existing setup on a vineyard located in Franconia.

• 

  Installation carrying the webcam, directional radio and a netatmo weather station

• 

  Resulting images during day.

The pictures during daytime were already pretty impressive, but at night you would only see a black screen. Not only annoying but also makes it hard to do nice timelapses. After searching for a while I found Foto-Webcam which runs a remote cam setup that does primarily use Canon EOS 1100D cams. I opted to build the same, however, I wanted to use a raspberry pi and as many standard components as possible.

Hardware

• Canon EOS 1100D
• Dummy-Akku
• 4 Channel Relais Module
• 5V Fan
• Rittal PK Box
• DHT22 Sensor
• PoE Splitter
• Waterproof LAN Connector

Software

• Debian Stretch
• gPhoto2
• Custom scripts for the trigger, most logic is on a remote server
• Custom scripts for backups
• Telegraf to write metrics to an InfluxDB

Features

• PoE Powered (48 V)
• System uses 5V with a peak of 2.5 A
• FAN On/Off via Relais
• Camera hard-reset via Relais
• Fan which blows hot air against the window
• Fully water-proof design (Rain from all directions)
• Temperature monitoring (w/ backup sensors)
• Pole mount
• Plastic shield for rain and sun protection

Cost

The whole setup costs about 350 € in total.
