Sample Thermal Images
A number of comments have come in with requests for thermal image samples taken by the Seek Thermal camera in day-to-day circumstances. A few cases are provided below. It can be seen that the temperature is not very accurate - for example, the temperature of a component in the refrigerator is reported as -13 C, when the compartment is set to be at 0 C. Also, the skin temperature is reported to be around 32 C, when it is obviously around 37 C (updated: see comments section).

Now that G+ Photos has exited G+, it's easier to share links to videos. Here's the one of the water boiling: https://goo.gl/photos/5rQx7kqJSDvzcWRGAganeshts - Saturday, May 2, 2015 - link
One of our fellow readers has provided a nice set of images. I have also added a page prior to the concluding section with some sample images.slashbinslashbash - Friday, May 1, 2015 - link
Having experienced crashing my car into a moose on a dark Colorado highway, I am extremely interested in this technology as some kind of early warning system for night driving in areas where there are likely to be deer or other large animals. I would love to see some samples of the output for far-away warm objects such as humans or other animals.Daniel Egger - Saturday, May 2, 2015 - link
You'd have to mount it outside of the car though as even the reflectivity of regular glass completely throws off the sensor, let alone car windshields and windows which usually usually coated with vaporized metal specifically to block IR and UV.DanNeely - Friday, May 1, 2015 - link
How are they getting a 720p video out of a 206x156 sensor? Unless they're able to jiggle the sensor back and forth a fraction of a pixel to interpolate a higher resolution, wouldn't 720p offer nothing except resizing artifacts over a lower resolution version?ganeshts - Friday, May 1, 2015 - link
It is upsampling with some tricks, as explained in this paper: http://www.sersc.org/journals/IJSH/vol8_no1_2014/5...In higher-end thermal imagers, the optical image sensor output is also used along with the thermal sensor's output to do a better job of the upsampling.

No doubts about that for certain applications, but for a majority of the use cases (checking for moving animals in the dark, finding the hotspots in a PC quickly, tracing clogs in plumbing etc.), the IR thermometers just won't cut it :) Trust me, I have used both - for different purposes :)carlwu - Friday, May 1, 2015 - link
I have this device. Around doors and windows, you can plainly see where there is heat loss in the winter time. Some areas you can address, others you can't.SilthDraeth - Friday, May 1, 2015 - link
I love how the guy in the comments has taken more useful pictures than the reviewer. Sure, taking the pictures the reviewer took contains data. But for god sake, take pictures of animals at night. Etc. For instance, I was contemplating this device, I was curious if on a pitch dark night, if I could see a coyote at 300 feet away in the darkness based on his heat signature. Obviously, coyotes aren't going to play nice, but, if a person would show up on an empty field at 300 feet it would be enough information for me to go off of.
