I got one of these, and I believe it's basically the same thing as the HTI HT-A2. The 320x240 sensor resolution is nice, but the lens is a wide angle (like 56 degrees or something). I saw some other threads about hacking the HT units. Just wondered if there would be a way to adjust the lens to get a smaller FOV, or is it just what it is? Would also be nice to turn off the center crosshair, but I think that would involve hacking the software, if it's even possible. I'm not that savvy with all that stuff.
