I use a Viofo A119. Pictures and video are quite clear, even at night, although plates can be difficult to read if they're more than about 50-60 feet away or moving too fast. It's a capacitor type and has GPS built in. I have it set to save the video in 5 minute clips, and with the 64GB SD card, it will save about 7 hours of video. I can also press a button to save either a picture or the current video clip it's recording so it won't record back over those. Thankfully I haven't needed it for anything legal but have used it a lot for saving some scenic drives we've been on. It also comes in handy, and is safer than the cell, for taking pictures of signs and things while driving.
