Thank you again for your contributions,
Redshift1340, thank you very much for your photos
, but I think I need more resolution. I want to detect birds to 80 feet away with the size of the head of your geese.
With your contributions, I am determined to go for the Therm-App HZ with 35mm lens. Currently, Thermal Expert does not have anything like that. For Thermal Expert (384x288) there are available only 6.8mm and 13mm lenses. A 25mm lens is only available for Thermal Expert-V1 (640x480), which will come out around $ 4,000 in 30Hz version. Too high for my initial idea.
Now the question is: I can recommend somewhere for purchase with sending to Spain?
Thank you very much for all your generous assistance.
Regards.
