As
@Gabacho said, SG stands for Street Guardian. Particularly the SG 9665GC for night recording and unbelievable aftersales support from
@jokiin and @Pier 28.
No I only have a Mobius A which I use as dashcam and action cam. I take it along on holidays and outings. I just put it in my pocket. It's about the size of my car's key fob as in my avatar. Sound is very good and just point it in the general direction. It's so discreet, people around is unaware I'm recording. It's, I guess one of the few that can do 80 minutes recording with it's builtin LiPo battery.
Personally I prefer 1080p or higher. Looks so much better. sharper, crisp recordings. Just see on youtube, play with settings. set it to HD 720 and 1080. You'll see what I mean.
This was taken last year at Fremont Street, Las Vegas. Unedited. Camera held at waist.
