Other thermal cameras are available ...

Digging around after my piece last week on the FLIR One I discovered that this isn't the only game in town when it comes to relatively inexpensive thermal imagers using smart phones for control.

I have already mentioned Andy Rawson's lo-res device, which I was told about in July 2013. Andy's web site now tells us that they have discontinued the camera because other inexpensive thermal cameras with higher resolution are now available. There was, however, another camera in the pipeline called Hema-Imager from Erik Beall, but this failed to reach its Kickstarter target. I get the feeling that these guys won't be giving up, and I wish them luck.

Israeli company Opgal have produced the Therm-App, which uses an Android phone as controller. This is more expensive that the FLIR One but has a higher thermal resolution (384 x 288 pixels and 7.4 to 14 microns ... which, of course, includes human body temperature) with a current price of $999 (full price $1600). This camera clips onto the back of your phone and connects via a small cable.

California-based Seek Thermal have announced a 206 by 156 pixel thermal camera add-on for both Android and iOS. It connects via micro USB or Lightning (depending on the device)and slots onto the bottom of your smart phone. Examples on their web site look good and so do the specs: vanadium oxide microbolometer detecting between 7.2 and 13 microns. The price, in the US, is $199.

All the companies marketing these inexpensive thermal cameras hope to build a market to help DIY (aka home improvement) by detecting hidden pipes and checking the temperature of food as well as seeing in the dark security.

There may be even more such devices out there ... if you know of one then let me know in the comments.
