Wanted an inexpensive discrete camera with decent day & night video quality, loop recording, and a motion detection feature.
Primarily for the motorhome to record travel videos and to provide insurance evidence in the event a driver swerves in front of the rolling 55,000 pounds of mass and then slams on the brakes and gets crushed like a bug. Also to be used in the car and truck.
Read several 2017 dash cam comparison reviews to get educated on the current state. Chose the Rexing V1 because of its small size and features and the 3,600+ reviews on Amazon with 83% at 4 or 5 stars. There is a GPS option for this camera at $30. It comes with a ~12 foot power cord, but I’m using that in the motorhome and truck. Purchased the hardwire kit for the car.
There are a lot of dash cams on the market and many different ways to install them. This step-by-step is just the way I did it.
This KL has the tech group’s large black mirror trim cover. Using less sticky two-sided tape on the camera mount for testing different camera locations, initially tried positioning it to the left of the mirror trim cover just below the humidity sensor, but the wide angle lens picked up the windshield shading to the right and the trim cover blocked part of the view. The bottom of the mirror trim cover provides the best centered eye-level view and least driver distraction. After some actual use, given the options provided in the camera’s software, found there is virtually no need to press buttons on the camera or view the screen while driving; which obviously would be a distraction anyway. The screen saver feature provides a timeout that turns off the screen which I set to 15 seconds. When threading the power wire, it’s a good idea to wrap it around the rearview mirror arm once or twice to provide slack for operating the camera buttons when the camera is removed from its mount. The Rexing V1 firmly attaches to its mount but is easy to remove too. Its storage temperature -5°F to 160°F. Operating temperature: 10°F to 140°F.
Wanted the option to run the camera off an always-on source or an ignition source. Always ON is good for the motion detection feature, e.g. parking in a public place. The ignition source is good for regular use where the camera turns on and starts recording when the ignition it turned to ACC or RUN, and then gracefully shuts down using its small rechargeable battery when the ignition is turned off.

find of an easy access to the harness containing the 12V outlet wires and pictures from @particleman
, decided to use a SPDT switch to allow choice of IGN, OFF, or BAT. (I had a DPDT switch on hand so I used that.) The pink/yellow wire at pin 1 is IGN powered and the red wire next to it at pin 2 is BAT powered. A body ground point is also available near the harness. The step-by-step installation is shown in pictures with captions here: https://drive.google.com/open?id=0B_...19VYmgwRHpseVk
Remove negative cable from battery and wait for 30 minutes before removing panels. Avoid airbags when routing wire around the A-pillar trim and under the dash. When reconnecting the battery cable there will be a check engine light that will go away after a few ignition cycles.
Used 2-amp fuses from the purchased inline fuse holder kit. The camera draws less than an amp. The ground wire to pin 7 is for the switch’s LED lights (which I did not use). Omit that wire to leave LEDs off.
