Hi, I'm looking for a dash cam and need your advice on what to buy in order to solve a rather specific line-of-business related need. The dash cam I'm looking for should overcome and fit these constraints:
- PRIMARY HURDLE
I need to fit about 30-40 hours of dash cam footage on a single microSD- hence, low bitrate on 1080p - less than 10 Mbps, ideally around 2-5 Mbps
- I could even go with 720p resolution, if the bitrate would just be under 5 Mbps
- thus, support for a microSD up to 64 or, ideally, 128 GB is a must
- SECONDARY HURDLE
(a very) portable installaton- the dash cam would change cars very frequently, multiple times a day, every day of the week
- it would always be used connected to a car-charger
- cars would need to have a small adhesive-based mount preinstalled on the windshield, something similar to a GoPro adhesive mount or a Garmin adhesive+magnetic mount (images below)
- dash cam installation in each car would need to be a simple click-on to that preinstalled mount (plus connecting the charger)
- Other must-haves
- wide-angle lens
- GPS-enabled
- date/time, GPS position and driving speed overlay on video
- Should haves (these features are not required, but would be welcome):
- GPS-metadata in a separate text file or embedded inside video frames
- WiFi / HTTP API
