Question: Is there playback on this unit, or do you have toconnect to a computer/
Document: You can, of course, rewind or fast-forward the videos on your computer.The 1080P video quality during the day was bright, sharp, and extremely clear. I probably won't bother with the 720P mode.------
The camera works well and is very clear but the mount needs to be improved. With the mount attached, this compact camera becomes quite large and very noticeable. Another problem is that the mount is very susceptible to vibration and this is very noticeable on playback. Unfortunately I will be sending it back.
It produces excellent high definition 1080p WDR videos with GPS data which, with the right software, will show a Google-type map of your route showing time, your speed, latitude/longitude etc.Some advice:1. The dash cam produces 2 files for each video. The video itself is in a .mov file while the GPS data file is an .nmea file. Proper software will integrate the two files for viewing on a computer.
speed displayed on the computer, not the camera video). However, I don't know if imager is as good, or if the software will be better (one can hope - Garmin has a pretty good recent record). Unfortunately, the Garmin GPS version 20 also seems to be significantly more expensive than what I paid for the f210 (~30% more). We'll see if that ends up being good value. In the meantime, I'll update as I gain more experience and if any reliability problems develop.
Just be sure to cut the rectangular piece of cardboard large enough to fill the rectangular base area of the hole so it won't fall out if you need to detach and reattach the cam.----The videos downloaded to your computer play just fine on a Mac computer using Quicktime Player (they're in .mov format).If you wish to play your videos simultaneously with the GPS information then Google for a 3rd party program called "Dashcam Viewer". It is available for both Mac and Windows.
While I can still gripe that the image isn't great compared to the state-of-the-art (or a regular consumer camera or camcorder), for a sub-$xxx unit, it's really impressive.
Update:  After several weeks with this dashcam (windshield cam), and buying a second, competitive unit (a cheaper E-Prance GT-680W, without GPS), I'm revising my review downward a star.
If I'd fiddled with it, I might have been able to get the software's Google Map tracking feature to work, but it simply wasn't worth the hassle. Compass rose is a joke, and speed update doesn't keep up with what's already on-screen. Video playback is far more cumbersome than any free package (i.e. Apple Quicktime, which it needs anyway), and one cannot go full-screen within the program (a problem on my small laptop).
My guess is less than 1 hr; maybe less than 15 min. The manual and some users note how the batteries will protect themselves by not charging in really hot conditions (we'll see). Unit can accept your manual input of speed camera locations, and give you reminder alerts later, if you want.
(Firmware update, HP? )In spite of the relatively small size of the unit, between the camera, mount, and cable, this is not something you'd want in your field of vision. Unfortunately, my EZ-Pass transponder already takes the best mounting position behind the rear view mirror. Ideally, my next dash-cam(s) will be built-in, or the size of a lipstick.
Answer: There is a play back on the unit itself. Do not need to connect to computer. Computer is only used for speed display and also gps.
