I will update this post continually (instead of writing multiple posts that could easily take over this blog) as I explore the capabilities of the Flir One infrared camera device. The updates will appear in descending order. The latest update was posted on December 19th, 2016.
DECEMBER 19, 2016: I know people who are getting much better results with their Flir One than I am. I realize my long rambling post here probably isn’t providing the best information because I’ve more or less taken the point-and-shoot approach. I want to turn this thing on, take a thermal image and immediately see something that’s useful — without having to modify the image later on using another application or program, because I don’t have time for anything else. Easily 95% of the images I get following that approach don’t show me anything that helps me. For people like me who may have day jobs, family responsibilities or other activities that don’t allow them much time to fiddle with something like this, I’m not sure I can recommend the Flir One. It’s too expensive and time-consuming. I’m not saying it doesn’t work, but in my experience so far, it’s definitely not something that produces great results just by plugging it in. It takes time and perhaps some knowledge of thermal imaging to get the most out of it.
DECEMBER 07, 2016: I took the following thermal images with my Flir One today. The automatic settings didn’t give me much to work with, so, again, I tried to adjust the settings on the fly and got various results. Using the Flir Tools app or the software on my computer would probably produce better images, but I don’t have time for that. If I can’t get a half-decent image by using the Flir One as I would my cell phone camera, then it could easily become yet another beekeeping chore that takes up more of my time. I’d rather instant results, not something that requires additional processing afterwards. So I’m aiming for simplicity at the moment even if it means I’m not utilizing the Flir One to its full potential. So… It was about -10°C when I took these pics, and no wind. It felt icy cold. Everything was frozen.
It was zero degree Celsius today (also known as the temperature at which water freezes). It was also extremely damp and miserable. Not a bad day to see if visual inspections of the clusters match the thermal images from my Flir One for Android camera device. Not a bad day to make some pre-winter adjustments to some of my hives too.
Hive #1. Other than dropping in some sugar over the top bars in a week or two, and maybe wrapping the hive, Hive #1 is just the way I like it.
A word about that top cover. Yup, it’s a piece of plywood I found in the corner of my shed. I put something heavy on top to keep it in place, but that’s it. I’ve had it on the hive for several months now, always meaning to replace it with a real top cover but never getting around to it. I may leave it on the hive all winter. Why not? The inside of the hive is warm and dry. Whether it’s a commercially made telescoping top cover dipped in wax with a metal cover, or a dirty piece of scrap plywood taken from a junk heap, it doesn’t seem to make any difference to the bees.
Here are some quick snapshots I took this morning of my hives using an infrared camera device attached to my cell phone. It doesn’t provide the most helpful readings at the moment, probably because it’s not cold enough outside to highlight the heat that’s radiating from the insides of the hives. I also used the default settings on the device. More precise calibrations might provide me with better images. But for now, here are my best guesses about what’s happening inside my hives according to these infrared images.
Here’s a low-rez infrared video of one of my beehives recorded through my “Flir One for Android” device connected to my Samsung Galaxy s7 smartphone.
Like most electronic beekeeping gadgets, it’s not for beekeepers on a budget and it isn’t really necessary. This is only a test recording. I’ll post more about it probably sometime in the winter, if I find a practical use for it.
All the photos and videos from the Flir One are low resolution, but it doesn’t matter.
