For as long as I have done electronics, I have dreamed about owning a thermal camera. Actually from my time in the army many years back I have dreamed about the huge thermal camera with cryo-cooled optics that we used for some anti-vehicle systems. Many times have I checked ebay and skipped the idea again, due to price.

My research showed me that there is a huge difference from the very cheap 8x8 pixel thermal cameras bare PCB modules, to the 32x32 handheld and up to the 160x120++ versions. The price seems to quadruple with the pixel count. I skipped looking at the smartphone versions as I wanted a stand alone model that was not dependant on a certain app and smartphone firmware to work.

In this video I am testing the HTi HT02D Thermal camera that I was able to get at 100$ on offer. This is not a paid/non-paid advertisement, my own money, test and conclusion.

Best bet to find these at a decent price is to run through ebay and send off a lot of "make offer" of 100$ on the 150-200$ auctions. But is it worth it? Lets find out!



Conclusion: You get thermal imaging with a fairly good temperature range that indicates precise enough to find the hottest chip on a PCB. Resolution and focal distance is not suited for small electronics, future improvements with a ZnSe laser lens for 4" focal distance will be an idea. Mis-alignment of thermal and normal camera is kind of a minor thing with the low resolution, but it is still a nuisance.

A future video will feature a teardown of the unit to see what sensor and electronics is used in this unit.

The price seems to quadruple with the pixel count.

I've been looking at this for some time and if you divide the cost of a camera by the number of pixels you get a surprisingly straight line (certainly once you cross the 160x120 threshhold).

There are obvious reasons for divergence - a high-end, calibrated camera with exquisite optics will be correspondingly more expensive - but, by and large, expect to pay something like 1 to 1.5 US cents per pixel. (As resolution increases the cost per pixel reduces slightly).

By my calculation a 1280x960 uncooled LWIR camera should cost about $12,000. We can but hope.

I guess nobody really had the motivation to build the spreadsheet and run the price analysis.

I will let you know what the price for 1920x1200 pixels is - should I hear back from Sierra Olympic.

The video quality from those Sierra Olympic cameras looks stunning.

When I win the lottery...

@Lord of nothing - I didn't spot anything higher than 640x512 on the Hikvision site. Did I miss something?
