During my first year of beekeeping I put a Google Nest security camera in front of one of my hives. I was fascinated with all their activities and the camera let me check up on them when I was stuck behind a desk at work.
Unfortunately the camera couldn't always keep up with the bee's fast movements; I would just see a pixilated mess. It could also only capture one hive at a time and it was either too close (but good for morning closeups) or too far away (but good for viewing orientation flights). So last year I upgraded the camera and got better images. But it still didn't feel good enough, so I tried another upgrade. And thus began my decent into webcam madness. I finally settled on a fancy Axis PTZ security camera that can zoom in/out and switch between hives.
I'm still playing with the setup, but it's LIVE streaming on YouTube now, 24x7. Take a look. You can read more about it on my BeeCam page.
