Mark West, a Brit now living in Norway, was convinced that he had some unwanted visitors in his garden. So, he decided to press into action a Raspberry Pi Zero as a security camera solution. He shopped at The Pi Hut and got hold of the Zero, the Pi NoIR Camera and a ZeroView sucker-mounting plate, together with some other components from various places. He then wrote Raspbian onto his SD card and then installed popular imaging solution Motion. He’s documented the entire process (thank goodness, because I really want to do this!) on his blog. There are also a couple of follow-up posts: here and here.
