Winter Thermal Image of hives
« on: January 23, 2014, 09:17:35 pm »
Borrowed a Thermal Imaging unit and recorded heat image from a couple hives.  You can see the cluster through the wood.  What do you think?

Images like the first one (the one showing the entire box) could be quite helpful as the thermal contours can been seen quite readily.  I have been contemplating getting the new FLIR unit that attaches to an iPhone.

I have my name on the FLIR email list when it's available. That would be cool to have.

Some more pictures.  You can see there are limitations.  When the cluster is close to the side of the hive, the hot spot glows.  When cluster is toward the center, the entire hive glows without a hot spot.  See below.




DM, the first picture is of a NUC stored inside my shop, somehow that made a difference in the heat pattern.

That's not necessarily a limitation.  The overall objective, at least for me here in Ontario winters, would be to determine whether there is a warm spot in my hive implying that the bees are still alive.  Determining the cluster location could be helpful as an indicator of their stores status.  Hence, anything identified as significantly warmer than ambient would be what I would be lookinig for.
In the first image you posted, where the bees appear to be approximately in the center of the box, I can see the thermal contours being detected through the side of the box.

I take your point.  I heard there is an attachment coming out for an iphone that displays IR.....If that really happens, the technology may be in reach of ordinary people.  :)

There is, indeed, supposed to be one coming out for iPhone 5 and 5s.  Like DLMKA, I have my name on the FLIR email list to be notified when it becomes available.  It is expected to be a little on the pricey side at $350.  On the other hand, any other sort of infrared camera starts at something well over $1,000 I think.

One of the neat things one would be able to do is to conduct weekly, or some periodic, "inspections" when it is otherwise too cold to open a hive to get a much better idea of colony status and when colonies die off, which could be helpful over long winters like we have here.  We can get five  month stretches during which the outdoor temperature rarely gets above the freezing point by more than a degree or two.  This winter has been really bad - there has been about one day in December and one day in January when bees might have been able to get out on cleansing flights.  It's looking like February could continue that trend.

The price of IR technology has really come down in the last few years. A entry level camera can be bought for about $1000.
I use IR almost daily on the job and carry a Level II certification. I bought a new camera recently that listed for $32000.00 last year for $8900.00. Last years,discontinued models can be had at a substantial discount.

Borrowed it from work. I was called for a cut out in a garage and thought it would tell me where they were.  They were yellow jackets and I could not see them.  I could see the light on the other side of the wall though.
