Video Camera?

My understanding of a "webcam" is its sort of used for real-time filming and streaming through your computer, or something like that! Not sure there's a niche for that in the allotment fraternity

Both the phones you've mentioned don't look cheap, unless I've googled(sorry duckduck'd) the wrong models. If I were you I'd at least try a test video on both?

There seems a heck of a lot of allotment/gardening videos on Youtube.

Even a walk around the plot filming with a talk-over of what is growing and plans for the future would be quite interesting I think?

Comparing mine and other plots layouts would be interesting to me?

I have just spoken to my son who reckons the Samsung would cope easily, so we shall see.
