Found out Testo has a Super Resolution patent-pending upgrade for their IR cameras. $395.00
Testo claims it increases resolution 1.6X and pixels 4X.
So, per those West German folks -
160x120 goes to 320x240
320x240 goes to a 640x480
640x480 goes to a 1280x960
Free upgraded & much improved software version is downloadable.
I’ll comment once I get the resolution upgrade and successfully install.
Testo claims the technology is already built inside their cameras and the upgrade is available through an activation code (they send via UPS?).
