Just thought I'd share a project I'm working on and get some advice/feedback on some of my future plans with it.
I realize this isn't the first attempt at something like this, just thought I'd share my spin on it.
"Skycam" as I call it, is a timelapse camera system using the Raspberry Pi 3 and V2 camera module. The camera is currently mounted on top of the roof taking pictures at a 1 minute interval during the day, and every 2 minutes during the night. It's powered over the remaining/unused signal wires from a CAT cable, housed in an ABS 4x4 junciton box with a 55mm lens filter as the camera window.

here's a gallery of some images/timelapse's I've captured so far: https://www.instagram.com/skycamyeg/
It's handled the Canadian winter conditions quite well so far, have yet to see how well it deals with rain. But can certainly handle snow.
I'm planning to roll out a few more of these camera's in some other locations facing various directions/points of interest.
My stretch goal is to have one of these setup atop a peak in the Canadian rocky mountains, solar powered with cellular connectivity. As you might guess that bring's with it a ton of challenges. Storage being one of the most obvious I plan to reduce the interval to something like 1 picture very 15 minutes from the current 1 picture/min. I also plan to have batteries in the system to act as a buffer when the days aren't as sunny.
I was hoping to get some input on these issues.
1. What is the best way to get cellular connectivity to a raspberry pi?
2. What are some power saving tricks I can employ to save power on the pi? ( I plan to use a Pi zero )
( I thought of implementing a system to actually shut off the pi in between interval's and turn back on before next capture. )
Any general suggestions for a project like this? anybody done similar?
