Fair enough John.
Three main questions.
What is the detector resolution?
What is the digital camera resolution?
What is the screen resolution?
Where are the temperature reference markers for hot or cold?
Can you adjust span or level?
Where is image information the thermogram?
1: The main background image is produced how?
2: As for the infrared spectrum, what type of lens are they using?
3: What software do they provide for the camera?
4: What software do they provide to produce a report?
Looks like internal software gimmickry, but that is just my opinion.
As well, I am sure you would not perform your class with a PRO-camera while your students used the full featured IR cameras FLIR and FLUKE provide.
Back in the day, when I first realized thermography was an assist to home inspecting, Germanium was the industry standard.
The FLUKE Ti32, owned by several InterNACHI homies, was considered the best affordable IR camera under $10,000. Lenes were Germanium (Ge) Good clear IR spectral image.
Now you have, Zinc Selenide (ZnSe), Zinc Sulfide (ZnS), Zinc Sulfide, MultiSpectral (ZnS MS), Silicon (Si), Calcium Flouride (CaF2). So capturing IR spectrum has come a long way, but has the lens and the true IR spectrum paid a price to minimum software packaging?
4x Oversampling is on the rise. Will this be a game changer?
It might be just an opinion but, I think the PRO-camera in question image clarity is basicly a blended image relying on software and maybe oversampling.
The smartphone, minus the phone, camera lens is the image resolution, be it raw or jpeg files, with a targeted IR spectrum overlay atop raw or jpeg files on the image.
FLIR utilized MSX to enhance a bold silhouette of black features transposed upon a thermogram.I see the same idea used in the train image only the blended has been refined.
Good quality FLIR and FLUKE cameras blend natural and IR spectrum on the camera screen, as well as in your computer, by the software they provided. You can provide any number of images to differentiate natural spectrum from IR spectrum.
TIS 10 9 Hz.
IMO, The PRO-camera offers little IR quality, as compared to higher end full featured cameras the start at just over $1,100.00 US.
I agree those app camera’s are a way to measure heat, but at what cost?
You get what you pay for in life. Don’t fool yourself into thinking you don’t.
So you better know what you are talking about when talking to someone that knows what they are listening to. If not, your business could be in for a rough ride.
Always great discussing IR with you John.
Wishing you much success as always.
