But what does it count now, exactly? Only the number of bees in the air in some space before the hive, right? It doesn't even say if they're going in or out? What exactly can be measured with this metric, apart from a very generic 'activity level'? Can it detect swarming, robbing, total bee count of a hive, bearding, anything useful?

Looks like the whole thing is up on GitHub so you're free to do what you want with it. Honestly, your comment comes off as complaining that the in-flight wifi is too slow. He found an interesting problem and did a great job documenting his process + approach, if that doesn't belong in HN I don't know what does.

As someone who grew up with bee hives, while "activity level" is generic, it's also very interesting at the same time. Spikes in "activity level" (like the chart shows at 4pm) would be very useful to me, meaning "Something abnormal is going on".

AFAIK it can't do this yet, but detecting bees in an image of the entrance is a first step towards doing any more advanced monitoring. A good next step is to track bees across successive frames, which gets you a) approximately how many bees enter/leave the camera view at each timestep and b) approximately how many bees enter/leave the hive at each timestamp. From that you can integrate to get the total number of bees moving in and out each day (which isn't the population, but is presumably correlated).

yeah, that's true it's only counting bees in one image, which i thought was part 1 of any of these other things. can you post your approach / code to doing any of these things you mention? i'd love to see what you've done so far.
