iSurfvilano, yes that's the correct hookup for the 12V socket over the front console, red / positive to the green/white wire and black / negative to a grounding point (the bolt.) I hardwired the rear cam to a splice on the back of the 12V socket in the trunk, since the rear cam doesn't need any transformer and works on 12V.
backcountryLR4, I purchased the cameras originally to document my trips off-road for my local LR club and to share with friends. I have tons of fun videos on a variety of trails. Since then, these cameras have also gotten me off one BS traffic ticket (I brought the video to traffic court to show the judge, and got the case against me dismissed), so they've definitely paid for themselves. I always think they could be useful to document the dynamics of an accident in the future - God forbid someone rear ends me, hit and run, etc. It's peace of mind mostly, and since you set and forget them these cameras are always there taping until you actually need the video for whatever reason.
You never know when or how that may be: just 2 days ago I used footage of the same stretch of road on two separate days (the day before and the day after a big rain storm here in Los Angeles) to prove to the gardeners of our gated community that a couple of large trees in the common area outside of our gate were slowly and dangerously toppling over the street due to all the rain - they originally claimed the trees "were always slanted that way" but sound and well rooted, and there was nothing to worry about... The morning after I submitted the video to the HOA it rained again, and the trees came crashing down on the road. Luckily, no damage to people, cars or other property, although the road was partially blocked for several hours while a crew cut up and cleaned up the mess. I'm proud to say, my camera
almost saved the day, LOL.
