I was also going to recommend [MENTION=93434]gshadow325[/MENTION] the king of all cams LOL
Lol. OK since I was dragged into this.
My two cents.
Dash cam needs are actually deeper than you think.
Dash cam needs. ....
-reliability, how does it accomplishes this?
-how does it record it
-how does it playback
-quality of video playback
-GPS
-field of vision
-rear camera
-flexibility of install
That being said. Can your candidates cover all these things?
I have bought tons of dash cams, eBay amazon, allibaba etc.
I have two dash cams sitting under my desk collecting dust. That i have left i couldn't give away.
I love my compustar dash.
Why?
-records in 720p HD, any higher is useless and takes up to much space.
-dual front and rear cameras
-records front and rear camera into one video.
-it can record by triggers. Motion or impact/gyroscope. These triggers are saved into a separate file and directory.
-there is parking mode that will record of it senses motion into a 20 second clip with the motion event being in the middle, it records the 10 seconds prior and 10 second after = 20 second clip. Same thing for impact.
-it also has parking mode,
-it has touch panel
-it needs to be hardwired. Stupid cigarette plug is dumb. It always corrupts SD cards in every dash cam I have tested. I don't care about the glowing reviews about the new version with the capacitor that keeps the SD card alive to avoid corrupted files. They always crash, then the dating is messed up etc.
-GPS antenna option, this will auto set date time and location, speed then map it onto Google maps.
-this unit requires SD reformatting every two weeks to keep the SD fresh. None of the other ones do this.
It does audio very well.
Here is a front camera clip. Money shot is at 17 sec mark. Keep in mind Facebook lowered the quality of the video also.

My money is on my compustar dash. You will get a reliable video when you need it. Dual cameras, audio, GPS, and touch panel. You can also configure it on your PC. It comes ready to roll right out of the box with everything you need down to the SD card and SD card to USB adapter.
Msrp is 300. Quality is remembered long after price is forgotten. Remember that!
