More please. 
How many hours does the camera record? Does it just loop around or start over every time you start the car?
I was just thinking about doing something like this, too. Here is what I found:
Has anyone used this one?
Nice illegal U-Turn while following him.
do you happen to have the brand or specs on the helmet cam?
Yeah, I knew someone would point that out.
My vehicle is equipped with emergency lighting front and rear which was activated. The Ranger tried to ditch me in the corner parking lot, and that was the shortest way to get back to him.
I do emergency comm and logistics for our county EMA and DHS, so I’ve got lights & sirens in addition to the cameras, but I rarely use them. If I come across a wreck or something in the road, I’ll run them to warn approaching traffic to slow down.
Like when this towtruck lost the pickup truck he was towing. People come over that hill doing 60 or so. Could have been ugly…
Or when little missy was in the fast lane doing 8 because her hood flew up on her windshield…
The camera is your ultimate witness. Notice how Ducati legally enters the right turn lane when the light changes. Notice how Mary Andretti in the UPS truck comes across 4 lanes of traffic to enter the right lane illegally. I jumped on the sidewalk to avoid the collision.
And, had I decided not to jam on the brakes, Soccer Mom would be buying me a new truck and more…
I looked at the “Hi-Res” dashcam. It’s the same manufacturer of the first one I ordered, and looking at the example footage, I’m still not impressed, although it certainly would be better than nothing. I think everyone should have one.
It’s funny, because looking at the test footage, the roads seemed very familiar; the trees, the traffic markings - everything just said “Atlanta” to me.
Sure enough, when he passed the McDonald’s I knew the road.
He starts at 6488 McDonough Blvd, NW here in Norcross and turns right to Jimmy Carter Blvd. Look on Google Maps & Street View it if you’re like me and have no discernable life.
