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 it could only capture one hive at a time and was either too close (but good for morning closeups) or too far away (but good for viewing orientation flights). So I upgraded to a PTZ camera and got to see a lot more of my apiary. But bees move fast and when there was a lot of movement the video became a pixilated mess. So I tried another upgrade. And another,,,
I'm always playing with the setup, but it's reliably streaming on YouTube now, 24x7. Take a look. You can read more about it on my BeeCam page.
