I used a couple different bike cams, one in front and one in rear to catch those guys purposefully moving over to shoulder to 'scare' us. My state does not require front license plates. The ones I have used could take photos too, and those were higher res than the video. So I set it to take a photo every 1/2 second, that seemed often enough. Though I had mounted camera upside down and had the camera rotate the images, bad idea, do that in bulk on your computer afterwards if needed, it slowed down the photo picture taking rate. There is also software to take those every 1/2 sec photos and make a movie.
