It's actually for still photography. The limitation on resolution of the video system is more one of bandwidth, both of composite video and of the microwave transmission system itself. There's only really 10MHz available at the frequency I intend to use for the big system, and although the 2.4GHz units have perhaps twice that, it all turns to poo when you try using a composite video source. Plus the available power is much lower, and the range suffers both from that and the fact that 2.4GHz has an enormous affinity for vegetation and takes every opportunity to lurk in it and never come out the other side.

Most of the digital still cameras output quite low frame rates on the video output, usually a maximum of around 15 FPS. It would be nice to have genuine video rates so I could combine the funtionality of the video and still cameras for one system I'm designing, but it's not critical as a separate video camera is very small and light.

I have used an Aiptek pen camera in the past for aerial photos, but the resolution simply isn't high enough for decent results, and higher res cameras all seem to be too big, or too expensive, or too slow, or just crap. The Ritz disposable camera was fairly close in many respects, but is really too slow to be used from a moving vehicle, a common problem with CMOS sensors. I really need a CCD one.
