There is a phone app you use, it connects via wifi to download videos and view any of the recordings.
It requires a hardline connection via micro-usb to run the camera. You would either have to run it from your cigarette lighter, or for a cleaner installation use something like an "add-a-fuse". You could put the Add-A-Fuse into your accessory panel under your dash board, or even through the firewall to the main fuse box in the engine bay if you want it to be powered even when it's parked so you can use features like parking mode.
I installed this on my truck not too long ago and I was thinking of posting some pictures on how I did it.
