         tally signal in (from VCR: switches the viewfinder and monitor headphone jack to AV in).
         Now, slight problem. I don't know how the signaling is supposed to work. start/stop and rec/review
         aren't simple HIGH/LOW signals, they have no voltage when hitting the reflected buttons.
-        The camera also doesn't respond to a LOW or HIGH on the tally sig in, 5 nor 12V.

         I should review the public schematics for the thing and figure it out.
         Also, the audio out appears to be quiet.

         Because this is a headless device and I shouldn't need a console to hit record (although
         the raspi creates a WiFi network to ssh into), I had to write
-        some software to trigger ffmpeg; so I wrote a daemon in C that reads GPIO pins from the front
-        panel or the camera (explained later) to start and stop the capture.
