"i want the best resolution camera back there, and the dual ones out there, including fitcamx, all have 1080p res. the viofo is 4k ... the last 5 cars have all had front and rear cameras, and at least 3 times we got punted in the rear, not once in the front. one time some dumbass ran in to us at the wendys drive thru. another was when we were stopped at a red lite."

"Using a fuse tap kit I hardwired it to a fuse that's only hot when the truck is on, but it has a separate connection that's always hot and provides constant power. So when it senses that the truck is on it records consistently. When it senses that the truck is off it goes into a monitoring mode that will only record when there's motion detected or the gyro is triggered. ... It has a battery monitor that senses the battery's voltage and will disable monitoring mode if the battery voltage gets too low. ... Works perfectly."
"Supports parking recording and collision detection."

"place the camera behind the mirror so I can’t see the main body of the camera. ... i almost forget it’s there."
"If you install it right then you can barely see the power wire from the drivers seat. ... the wire is routed under the cover for the rear view mirror mount and under the headliner to the pillar and down to the fuse panel in the drivers foot board. ... With the hardwire kit you just insert two fuses and that’s it."
"Ultra slim RF cables that make it easy to run to the back."
