I'm hoping supply of the new zero will level out soon so I can get one and a camera and see what sort of load it takes. You can get a solar usb charger 20w for around Â40 and I would imagine that, and battery pack and controller to switch the power on and off sensibly would be a start! Tom te tom te tomI'd be tempted to go straight for the Pi3 with wifi
The on-board wi-fi is good, but not that good - he needs 100m - that would need an external antennae soldering on, and the Pi3 is quite power hungry already. A Zero is a much better option for a power + battery point of view.
.. then you can connect direct to it from the house. Range should be adequate. If you really feel brave, you can run either motion/zoneminder/opencv on it for motion-detect and/or capture if you like. I'm sure I've seen some demos of exactly this setup, but google will be as good as source as any for this.
More cpu/gpu == more power == bigger batteries. It's all a trade-off here. (The Pi Camera uses GPU to do the imaging and conversion from raw to whatever stream du jour is)
TomB has done a lot with openCv on a Pi - he might have some input here... Gordon
