I got one of these to debug thermal leakage. I very much like it. Here's a shot of my laptop: http://bochs.info/img/IMG_0676-20140822-211311.png If anyone's curious about something specific, I'll gladly take requests for photos. It's super interesting to see things from a temperature perspective.

What's the maximum distance that the camera can get infrared image from? If you are outside can you see people from a deletion enter distance, 20-30 feet away?

I want to get one but they launched their product disastrously close to the iphone6 launch. I'm going to wait for their iPhone 6 version because I don't intend to keep my iphone5 around.

I still have my iPhone 4 but it is gathering dust and the batteries are dead so I don't want to waste $350 on something similar.

I haven't tested that exactly yet, but here's a support response I got from FLIR on temperature accuracy:

> At about 100m, you can see the heat signature of a person. However, atmospheric conditions can influence the visible range. Dry, clear weather will provide a greater range than rainy, foggy or humid conditions as water in the atmosphere can absorb infrared radiation before reaching the sensor.

> The spot temperature is a close representation reading for conditions testing and monitoring. It may vary 2 degrees from actual temperature.

Is there something specific about the camera in the Iphone that would preclude doing a similar thing to android phones? Or is it just a matter of uniformity of the housing?

That is probably precisely the reason why it's not available for Android, there are hundreds of different physical form factors and many more configurations.

Yeah, not so much the phone's camera as figuring out how to strap the thermal camera on and plug it in. It has its own internal battery as well, so it's not the smallest load.

I'm not really thrilled about it being for a specific phone that is likely to have a physical form factor not guaranteed to have any particular lifetime.

Even with that... the non-iphone versions they previously sold were thousands of dollars. This is a huge leap in affordability even if you have to buy an old iphone 5 to go with it.

For instance, the E4 they sell is $1000 and up.

Earlier quoted context omitted.

The photos I've been taking come out as 535x401. It looks like the visible light camera it uses is just VGA (640x480), but the thermal camera resolution is probably the bottleneck anyway.

Can you take a thermal-only picture too? The cheapest FLIR camera so far has a (afaik) 240x240 low resolution IR sensor. So they maybe combine an upscaled IR image over an actual VGA camera photo.

The only photo settings in the current app:

- Color (you can pick how the color scale is rendered)

- Sensitivity (matte, semi-matte, semi-glossy, glossy)

They're releasing a few more apps of their own and an SDK, so it might be possible in the future to get the raw IR image.

I used one of these at MacWorld, and asked the rep what distance it was effective at, their answer was less than 15 feet.

What do you mean by effective? FLIR's support told me it can pick up the heat signature of a person at 100 meters. I went outside earlier and it seemed alright at a long distance. It's not like it simply doesn't work after 15'.

I think due to the resolution many of the interesting things you can do with it will end up being at short range.

I also noticed it reports the sun's temperature as "> 212º F" so there's that.

It's worse than that, most likely. The cheapest FLIR cameras have 320x240 IR sensors, but they downsample to 80x60 unless you either pony up several thousand dollars for the E8 model or buy a $1000 E4 and hack it. There's no way they're enabling 320x240 IR imaging in a $350 iPhone peripheral. If they were, they'd be trumpeting it all over their marketing literature, rather than neglecting to mention resolution at all as they're doing.

And yes, launching this thing a few days before the iPhone 6 announcement is about the stupidest goddamn marketing move since the Osborne 1. Somebody needs to lose their job over that.

In FLIR's defense, 80x60 is still very useful for a lot of things. The ability to overlay low-resolution IR and moderate-resolution visual images is sort of a cheesy gimmick, but it makes the low-res IR sensors vastly more useful. (My E4 is hacked for 320x240 support, so I usually turn the MSX overlay off.)

Just a note on UX and visualization: Mapping temperature to a color/wavelength is not the perceptually best way to convey data. Humans are not good at estimating the distance between two data points when using a rainbow color scale. Using luminosity would be much better, or even a color scheme that uses saturation. See e.g. http://colorbrewer2.org/. Different schemes are perceptually good to use depending on whether your data is categorical, scalar or(/and) has a fixed center value that has semantic meaning. It doesn't look like the actual camera uses this mapping, but the demo pictures on the front page do. I'm not sure which color scale is used for the actual camera interface.

A side note to this: Sometimes, users expect a particular color mapping and will object to using a coloring scheme that is perceptually better. E.g. doctors often view diffusion tensor images where each point in the image represents a 3-dimensional value, using the RGB colors for each dimension. This is a perceptually horrific choice, since practical demonstrations would reveal that there is significant perceptual ambiguity when viewing data represented like this. But an engineer once made a prototype that used this mapping, and now the operators are unwilling to change their habits.
