Hello,
You will find almost every Hard Drive based camcorder is going to shut down with just a little vibration. They actually have a drop sensor inside that gets falsely triggered and shuts them down prematurely to save the write head when you drop the camera.
Try another camcorder, but finding one that supports analog A/V in is going to be tricky, which eliminates the ability to use remote lenses outside the plane.
If you want to get serious about on-board video, you can certainly check out the advanced systems that we offer:
