This assumes a uniform distribution where one isn't obvious. Some places are bound to have more security than others.
- ska 7y agoIt doesn't really make that assumption unless you assume simple linear extrapolation. It wouldn't be easy but I expect a decent modeling and extrapolation scheme could be devised. I don't think it matters much though, as a simple count of cameras isn't so useful (especially with them being so cheap now). How many cameras is less important than what they cover and what they are connected to.
- cowpig 7y agoIf you cut up the municipality into uniform sizes, and then randomly sample from that to do your counts it should account for that problem I think.
- greggman2 7y agoIs that true? I'd only guess there are more cameras in Times Square than Wastingtion Square in NYC. I don't know how you would divide most cities into areas of uniform camera coverage such that totaling one area is representative of all other areas in that city. Most cities have several hot spots
