Ah well, only those two I can find which I guess would work for sampling thermal imaging, they are in the £120-150 range on ebay. Can probably work with 13mm but 7.5mm or wider would be more ideal.
Indeed, I think shall probably pickup a 13mm and a 7.5mm, see how they work out for me, for an average of £120 each they can't be bad. Maybe make more sense to get the DH-TPC-BF5421-T in 13mm, assuming it is the newer and better camera, when compared to the BF2221-HTM
I have a couple of spots with hedgerows and shrub/tree growth which these should work well for, all out of range for normal cameras.
Yes, 7.5 to 13mm is not an ideal range, I suspect these would get mounted 16 feet up on the roofline looking down and out but even then still quite a narrow field of view. I guess the old for £100 vs £300 for the latest model was and is tempting. Some more research required I guess.
Yes. If it looks like a large tiger, it's a housecat. If it looks like a large moose, it's a deer. If it hops like a rabbit, it's a rabbit. You get to learn this after a while.
