Nice! I've been putting off hardwiring my dash cam for almost a year but I may go ahead and do it.
FYI, I have an OjoCam Pro Mini 0801 that I've been using since last April and I actually really like it. The price on Newegg is up to $120 but I paid significantly less than that (I don't remember the exact price). Beware, though, that a lot of eBay sellers are selling counterfeit versions of these.
The video is pretty good and includes all the standard dash cam goodies (1080p recording, audio recording optional, G sensor [so if you get into an accident it automatically flags and locks the video event so it can't be recorded over], GPS [the user interface for playback maps your rides along with your mph at the time], parking mode, etc.
The newest version of that cam is the 0806 model and has increased video quality (1296P vs 1080P), lane departure warning, front collision warning, etc. I may buy that and sell my 0801 for cheap.
Here's video from my 0801.
Make sure you choose 1080p. Pardon the music. It was from their free selection.
