In the kit you get two water resistant cameras, a water resistant button, gps unit, DVR unit, and a bunch of 3M sticky stuff. Build quality looks to be quite nice.
Installation was pretty easy, I know nothing at all about electronics so I had troubles getting the power sorted out, the instructions say to wire directly to the battery, but that would leave the unit always on. So after a lot of frustration and google, I wired the negative to the battery and the positive to the headlight fuse (I have no idea how or why this works, and I hope i’m not doing any damage to anything by doing this). So unit now powers on and off with the ignition.
