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.

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.

Testing & Current Status

I've done some very basic tests in the shower. Stuffed the case with rags and closed it, positioned it and then just sprayed on it from all sides, including shower settings with higher pressure than normal rain would have (probably not even in storm conditions with wind added). The test was successful and I couldn't find any water intrusions.

Because it is going to be put on a pole and modifications are very hard to add in later, I decided to try it on my balcony for a few days. This test was also successful. Now the camera is in Franconia, but not installed on the pole yet. It was installed in a garden temporarily to ensure that it works long-term without any problems. So far so good!
