WallyWorld, a.k.a. Wal-Mart, actually started carrying a "Dash Cam" and even featured it by putting it in one of their weekly fliers. I had shopped their clearance section and was wandering around the store and saw it. It is amazing the things people wear or don't wear when running out to WallyWorld. It is a world unlike any other.
ANYWAY, they are selling it for $39.99 and it writes AVI files if I recall correctly. No telling the quality of the CCD. 1080p supposedly but don't recall the exact specs. Probably would do far better by buying one of Dave's recommendation for around $100 US, problem is the knock-offs are out there so you have to sort out those when buying as well as getting the version with the features you are going to use. They make them with WiFi sync and without as well as various resolutions in image capabilities....older version I would imagine. They are mimicking the path that the GoPro has developed. Imitation being the ultimate form of flattery and corporate warfare to steal sales.
Time to cut the grass...before storms set in the next several days.
