I had a bit of a debate with a mate about the camera mount - with people that I trust when it comes to these things.
Having the camera mounted on the rear seat, facing forwards will give acceptable, but not great pictures. Mounting it to the driver's seat was an option, but there is a big question mark over safety - especially in a rear ender. If only the passenger seat headrest clips were intact!
Thinking about some different options and thought that the back-seat passenger grab rails might make a good option.
They have two beefy screws in them and are clearly designed to take a load. I had some more umbrella shaft (oo-er) and had some bits of plating and brackets knocking around.
With the passenger side grab handle off, I set to:
The brackets are actually designed for holding spades and stuff in the shed, are 1mm thick and the limbs have a rib in them so they are quite rigid. Even more so when the are all screwed together. Need to change the screws for dome heads, as the countersunk ones make me cringe - but I didn't have any to hand. Will also give it a paint to smarten it up.
I plonked my iphone on the mount for a test view:
Much better.
If there is a pax, I'll probably just swap to rear facing rather than trying to sneak a view past their head.
Oh, and the camera will probably be suspended upside down. I've had to film like this before and it is easily corrected during editing.
