This practical guide is an annex to the paper: PICT: A low-cost, modular, open-source camera trap system to study plant-insect interactions. Methods in Ecology and Evolution (Droissart V., Azandi L., Onguene E.R., Savignac M., Smith T.B., Deblauwe V. 2021). https://doi.org/10.1111/2041-210X.13618
PICT (Plant-insect Interactions Camera Trap) is an inexpensive, DIY, camera trap system based on the open-source Raspberry Pi nano-computer. It is designed to continuously film insect or other small animal activity in the wild. PICT is an affordable and powerful solution for those who desire to film for extended time in remote places. It can be remotely controlled within up to 100 meters using a smartphone, a tablet or a laptop. PICT can be used for a variety of purposes including, and not limited to, plant-insect interactions, bird feeding or nesting, amphibians’ nocturnal activities, predation by reptiles, insect’s behaviour.
The guide provides step-by-step instructions to build, set-up, and use a PICT. It is intended to be accessible to anyone with minimal handiwork or computer skills. The interaction with PICT has been extensively tested on Windows (7 and 10) computers and Android (7,8, 9 and 10) smartphones. In addition, the guide provides solutions for macOS, iOS.
The guide is provided as a PDF file (.pdf). The python and Matlab codes provided in the guide are also available here as text files. Note that the latter format must be preferred to copy-paste the content. PDF file format does not maintain space characters used for indentation which will ultimately result in a unusable python code.
