When it comes to dash cam video quality, the number on the box only tells half the story. Resolution matters, and 1080p, 2K and 4K each have their place, but it is the sensor behind the lens that decides whether you get clear, readable proof or a blurry smudge when you need to make out a number plate. This guide breaks down resolution, frame rate, HDR and the Sony sensors that separate a great camera from a cheap one, all in plain English for Australian drivers.

Whether you are weighing up a budget 1080p rear camera or a full 4K front-and-rear setup, understanding how these specs work together helps you spend your money where it counts. Read on to learn what resolution you actually need, why megapixels are not everything, and how to pick a camera that delivers sharp footage day and night. Not sure which suits your car?
