Just received my Powerucc Panorama2, and haven't had time to update the BIOS yet. Testing next week. Some general observati0ns --
1. It's a neat, trim, self-contained package. It'll look good in the car. Without that English PDF owner manual I'd be flummoxed, though!
2. This selection was versus a Cowon AW-1, since I've had excellent results with Cowon Z2 mp3 players. I don't need Wifi access, though. In addition, Cowon's in the process of getting their AF-1 to market (replacing the current AE-1), which might be a better future candidate (and might wind up in another of our cars).
3. GPS-on-video is a nicety, however, all our driving is on familiar roadways. No need for that, nor even a correct timestamp on recorded video. (The timestamp is more applicable to parking mode.)
4. Prior to purchasing a "real" dashcam, I've been using GoPro Hero2 cameras attached to internal seat headrests, with the field of vision reduced to 90%. When you film from the back seat or attached to a front-seat headrest, you can include other details in your recorded images: the driver, speedometer, any other GPS devices like a TomTom or Garmin. One Hero2 faces forward; one reverse. Older files are overwritten. HOWEVER, there's no parking mode, these cameras cost more than dashcams like the Panorama2, and they need constant attention for optimal results. The Panorama 2 is essentially a "set it and forget it" device, despite the admonition to reformat your SD card "weekly, or at least monthly".
5. Obviously the rationale for a dashcam is that I've been near-burned recently. If my July 3rd accident hadn't been caught on an external camera, it would have been he-said, he-said, and would have cost me $2K out of pocket. Paying a tenth of that for a Panorama2 is a no-brainer, especially since you can cycle older-generation cameras to rear-view monitoring. Parking mode conceivably could have saved us $1K 2 years ago when we were hit in the side in street parking in New York City. But for best protection, we're going to have to wait another generation for parking mode with full 360-degree coverage.
6. 1920x1080 "full HD" is the minimum we consider for a dashcam. Going from 30 to 60fps achieves playback smoothness, but it's not worth stepping down to 720p.
7. (This is from real life.) Do not expect your insurer or law enforcement to have any capacity to receive OR view your important videos, because the files will be an order of magnitude larger than most "non-geeks" can handle. If you are in a situation where you have a created video, it is very important that (a) you don't edit the original, and (b) maintain strict control over custody of the file(s). Quickly identify the material in writing -- date of file, size, length of video, how created -- and make sure the insurer/LE acknowledges you have it. Be prepared to show it on your own laptop (or at least from a thumb drive). Burn copies of your originals to disc and send them to the insurer or LE party for their records. NOTE that many corporate organizations won't even allow videolan.org (vlc.exe) to even be INSTALLED on one of their computers -- and at any rate, good luck finding one with an HD-capable monitor. They'll eventually be able to access the files, but this is 2013 ... expect them to have that as native capacity in 2018 or later.
