Really low resolution images.
Blurry circle at the top and bottom of the image.
Better quality image than gen 2, no blurry circle in the sky, but a car shaped blur at the bottom.
Even better quality of the image, no blurry circle at the top, car shaped blur at the bottom usually has a blue tint to it. Colors are usually more vibrant.
The camera is mounted lower on the car (for privacy reasons) which makes the footage seem lower than usual. The blur of the car is therefore also bigger (not to be confused with gen 2; it is not circular and there is no blur at the top of the image). Taiwan often has a wide blur as well, but the camera is not mounted as low.
A person wears a backpack with a camera attached to it. Blurs can be different: car shaped, person shaped or gen 2 blur.
