Let's say I want to buy a fixed lens camera that can cover a particular section outside my house. I want it to be very specific like from edge to edge of my property lines, very minimal to no skies. What tool can I use so I know exactly what lens characters to look for when shopping for a camera? Or is this mostly just trial and error? I've purchased cameras in the past and only to find out they gave me either way more or way less coverage than I needed.
I want a camera that are wide enough to cover what I need but not spill over into my neighbor's yard. There's also a narrow area that I need to cover and I don't want to get one that's too wide and see walls on both sides, or one that's too narrow and can't cover what I need.
Are there phone apps out there that can use your phone's FOV as a baseline so you can just snap a picture, draw the area that you want covered and it'll calculate for you exactly what FOV/Focal Length/Aspect Ratio you need? Or do I just need to measure the angle myself the old fashion way like sticking my arms out, etc.?
