i'm currently looking at various dash cam models and what puzzles me is that most cams seem to be able to measure the battery voltage and display it, but none seems to have a feature where you can configure 'if voltage < x, turn off'. my impression is that either no discharge prevention is offered at all or it's offered at a rather high cost as an external box you have to find a place for in your car as well.
is this pure marketing or is there a good reason why this important feature is not realized in software? or are there models capable of doing this without external power saver boxes and i just haven't found them yet?
