Re: [Paparazzi-devel] Connecting a camera to the autopilot (Lisa/L)

[Gareth Roberts]

We've nearly crashed planes because of it.
The best solution I've found is to use an analogue camera but split the video 
feed (either airside or groundside depending on processing requirements) then 
feed that back into a digitizer - I use a crappy Pinnacle DVC-100).  That way 
the computer gets the video feed, and the pilot gets a fairly reliable 
low-latency feed to her video goggles/screen.  I s'pose you could use one of 
the little SoC digitizers if you wanted to do it airside, split the camera feed 
just before the transmitter, and feed the result to Lisa.
