The main issue with a small FOV is that its going to miss potentially important details that even your human eye would've caught. I suspect the bare minimum you should seek today is 120 which is nearly what the human eye can see. Many cameras are measured with something called "wide angle view" this is measured diagonally so its not necessarily a FOV but to at least get what your human eye sees you'll want at least 140 of that number which many cameras easily achieve these days. If the Garmin speak plus calculated its FOV based on view angle thus the 82 was measured diagonally...then it might be disastrously small potentially missing far more details than just plain peripheral vision.will888 wrote: ↑ I have not seen the Garmin speak plus with Alexa discussed in this thread. The only thing that seems like a deal killer is the field of view being really small at 82 degrees. I have seen videos from reviews and it doesn't seem like that bad of a problem. Can anyone comment on how important it is to have a really wide field of view and what angle should be considered a minimum.
Ideally the bigger the FOV the better as it will show details that even you behind the wheel might've not caught. In the event of any incident the more information the camera can capture the more likely all can see the truth of what happened.
