Recently, at this post HERE, I asked for ideas for dash cam with sound to be used to record the driver and a police officer outside the driver's window during a traffic stop. I termed such dash cam a "taxi dash cam". The suggestion from those that helped me find a solution was overwhelmingly in favor of the Mobius C3 dash cam. Now, as I continue to absorb (and digest!) general information on this site about dash cams, I stumbled upon the rear view mirror (RVM) cams forum, and have paused to reconsider why a RVM dash cam wouldn't do the job of a taxi dash cam, and do it brilliantly. (1) Stealthy? - it can't get any stealthier; (2) Good audio sound? - most include fair-to-good quality microphones; (3) Set-it-and-forget-it? - obviously; (4) Good FoV/coverage? - since the RVM it already tilted (with respect to the plane of the vehicle's front), it seems that, even at 100° coverage, both the driver and the officer would be fully visible; (5) Remote video recording (RVR)? - No, but since the RVM cam is an actual component of the vehicle, remote video recording becomes a moot point...as a part of the vehicle is it most stealthy and -thus- safeguarding the microSD card is no longer as much of a priority as for dash cams that sit announcing themselves on the front windshield of the vehicle. In short, it seems that a rear view mirror cam would be a great fit to work the role of a taxi dash cam. So I am wondering if anyone would care to share their opinions and/or comments before I go out there and make my purchase. Thanks!
