one big glaring weakness, no audio. ( atleast that i could find)
You really want that. Thinga like a horn blaring could be the difference from fualt or not in an accident. With thr riots and other civil unrest. Having it record some one making a threat too you is invaluable. Its no longer your word vs thiers, its this is what was said.
I do not want sound. We have dual camera systems in our CMV's. They have sound, but the mode is set extremely low. If I hear the music in the vehicle, I will notify the driver to done it down. These will not pickup conversations, most shouting, and they don't even pickup the City or Highway horns.
What I do want is the cabin view. This will show your alertness, your physical actions and any actions against your person, and it will show your warning attempts. It is one thing for the camera to show your expressions and lip movements, but you do not want a jury listening to you scream at the "F'N A Holes".
This camera has a download feature through an app. I would investigate what it takes to grab the video. You want it downloaded quickly in these situations to assure it isn't lost due to destruction.
