Hardwiring dashcam: ground terminal?

I would like to hardwire my dashcam with parking mode. I believe there are switched, and constant power sources in the passenger footwell fusebox.

Is there a good grounding location?

Re: Hardwiring dashcam: ground terminal?

Put your head down low in the foot-well and look up above the fuse-box. There is a single Torx screw which makes a great grounding point. There is also a ground point behind a panel in the foot-well I think - haven't figured out quite where. It is shown in a diagram for installing the BMW dash camera.

Isn't there a dashcam out there that doesn't require any wiring? Rechargeable? The wiring or wires being all over the the place is the main reason why I've not gotten one yet.

Thanks for that ! Didn't realize they had such a thorough manual.

I used my multimeter and found that the post for the twist screws that hold the fusebox in place is an adequate ground. We'll see how this works out over time.

Nope.

Not enough battery life with current tech. For example - a small GoPro (battery) camera used extensively by outdoor enthusiasts, set for wide angle and high res would film for about 20 minutes before needing a recharge.

The grounding point that I chose did not work well. It kept losing the connection even after securing it with tape.

Here is that grounding point mentioned by Mark in post #2.
I had to slightly pop out the black panel to get the screwdriver at the torx screw. Works great!

I was able to tap into the wiring harness in the rear-view mirror shroud for switched +12V and GND. Enlarged one of the vent holes at the bottom of the shroud to bring out the USB cable. No need to route the cable all the way to the fuse box!
