My Flir thermal imaging camera is a finicky piece of gear that never consistently produces a readable or useful thermal image of my beehives or, more specially, the cluster of bees living in the hives.
These thermal images show the difference between a hive with the bees clustering low (with plenty of honey above them) and bees clustering high (possibly running low on honey).
I can’t imagine the bees in any of my tall hives are running low on honey. Most of my hives were packed with honey going into the winter. But you never know. The first time I lost a colony to starvation was around this of the year. So…

A thermal imaging video I posted yesterday shows where my bees are clustering inside their hives, more or less. The video was created by combining high-resolution footage from my cheap cell phone camera with low-resolution footage from my expensive Flir One For Android thermal imaging device. But I also have one of these nice and cheap devices advertised as: “Infrared Thermometer Laser Industrial Temperature Gun Non-Contact with Backlight -50-380°C（NOT for Humans).”
Laser Gun Thermometer.
I wanted to see if the laser gun — which is about 25 times cheaper than the cheapest Flir One device — might work just as well as a thermal imaging device. Yeah, I know it won’t work as well, per se, but is it good enough for my backyard beekeeping brethren on a budget? I’ll tell you right now, the answer is maybe. Maybe even probably.

Here’s another video from February 1st of me testing out my Flir One thingamuhbob that attaches to my cell phone to produce thermal images in low res video and pics.
As usual, the results are okay but is it worth the money for beekeepers on a budget? I don’t know.
This video was shot after the Snowmageddon event that occurred in Newfoundland on January 17th, 2020. I’ll post a detailed video of that as soon as I can find the time to slap something together.
Here’s a short video that demonstrates what I typically experience when I plug in my Flir One thermal imaging camera:
August 2019 Introduction: I fooled around with a Flir One For Android thermal imaging device for about three years. It’s not a device for beekeepers on a budget. I doubt I would have picked it up myself if I didn’t get it as a birthday gift. I wouldn’t call it essential for the kind of backyard beekeeping that I do, but I have to confess that I got in the habit of using it often in the winter, even though the battery doesn’t last much longer than five minutes on a typical freezing Newfoundland winter day. It doesn’t give me the most accurate thermal images of bees, but it provides an indication of whether or not the cluster is big or small, dead or alive, or dying. I don’t have to tap on the side of the hive and listen to the roar of the bees to see how they are doing. I don’t have to listen carefully with my stethoscope. Typically, I plug the device into my Android phone, turn everything on and then run out to my hives and take as many photos as I can as quickly as possible before the battery dies. I don’t think it ever lasts more than 10 minutes. I have my doubts that the built-in battery was designed for cold places like Newfoundland. Here are some sample images and video to give an idea of how it played it out for me.
An example of using the Flir One in the dark:
