@Gawdphather Vibration concern isn't out of durability for the camera, but the camera shaking violently while the stump grinder is biting wood. To mount it without all that vibration, I need to affix the mount to the tractor itself and use conduit or something to create an arm that I can lock next to or behind the grinder. Maybe it won't be as bad as I anticipate it will, but we'll see.
Tractor has a cab, so the panel will be sheltered.
I'll probably try wireless cameras (for flexibility)
