i fit these at work and they seem to be spot on. only issue we have had is with the memory cards playing up. since changing to "better" cards we have had no issues. they are small enought to go behind the interior mirror so you can fit and forget. just remember to put it in the wiper sweep. suprising how many are not. the ones i posted are hardwired in unlike the one in the vid, so that you cant forget to remove it and accidently record over footage.
