I recently purchased an IR Thermal Camera. I wanted to share some images, and some thoughts about what's available, because there are almost zero reviews out there, and they all seem to gloss over something important.
And I suppose-this being the internet- that I need to disclose that I have absolutely no relationship with Seek Thermal, or any camera business or retailer, in any way, shape, or form. I'm just a guy who wanted a new toy, and IR cameras cropped up in one of the internet forums I read.
And so you don't have to read this whole thing, couple dozen sentences.. I'll disclose the detail I found that was hardly mentioned, and only in passing... Thermal cameras don't have very many pixels.
Let me give you some background. Back in 1999, I bought my first digital camera, thereby starting a very intense hobby. That camera had a whopping 1.2 million pixels. 1280 by 960 pixels. Typical full-size DSLR's now have 30 and up million pixels. Your phone probably has over 9 million pixels. The size and number of those pixels determine how tiny are the details that you see. Smaller, more numerous pixels give you the ability to see smaller details in the image, and to zoom-in if you desire.
In some cases, you may only need one pixel. "What!?" you exclaim? Yeah. If you have an IR 'gun' thermal device, it basically has one pixel. It reports the average temperature from a circular area on the surface of whatever you have pointed it at.
You'd think that thermal cameras would have millions, hell-at least 10's of thousands of pixels, right? Well some very expensive IR cams, from big-name companies, have 2,400. That's an array of just 80 x 60 pixels. That's not a lot of resolution. Sometimes, they overlay this temp data with a visible-light image, which fools you into thinking you see better thermal detail than you actually do. And every video broadcast you've seen does the exact same thing-to save on bandwidth.
So, anyway, the CompactPRO that I bought has 76,800 pixels - 320 x 240, and produces the images shown in the following link. I wasn't expecting this level of performance, I'm *very* pleased with it, and maybe this post will keep some of you from buying less than you might need.
