Kodak (name licensed to JK Imaging) SP360. I mount it to windshield using their suction cup mount. Records to SD in 10 min (IIRC) loops. Has a setting to power on and off with the vehicle. Fun little gadget to use for many things. Stuck it on a letter when our daughter was marching in her HS band for a night parade. They twirl the letters... Underwater case is fun to use. Mount it on one of our dogs - to their harness - when we walk, for fun at first, but now for security. Plenty of loose dogs around, and we do have to pepper spray the loose ones from time to time.
There are many cameras now marketed for driving. I have seen them at Costco. I like the 360cam since it shows more, including me. On the other hand, not showing me might be better if I mess up, but that is not my concern. If I mess up, I can accept that. I just want to be sure the truth comes out. Same with the cams around the house.
I am really not the worrying type, but it is so easy to record things, and is a nice peace of mind.
