No reply? Good post!
I also love those unusual toys, I have a Bullard and a MSA 4000 in my collection, both are 320X240 fast rate, and both are firefighter series, so they are rugged and have very huge FOV(near 60 degrees), the bullard is BST sensor and the MSA is VOX sensor, the MSA is even faster than bullard(maybe 60Hz?), and the VOX picture have more gray-detail than BST, but it need shutter to calibrate which may interrupt the video, however the BST use a continues chopper, and the picture have a black contour around hot(white) things...
So will you be able to hack a scout 160 or 240 to 320? I think 640 is not the same hardware so I didn't expect that.
