Although the VD1’s Sony Starvis imaging sensor doesn’t technically record natively 4K, since it’s a 5MP sensor and not 8.3MP – a marketing sleight of hand played by a lot of dash cam companies – the footage is upscaled to 4K resolution and looks very good indeed.
As you can see from my sample recordings below, footage captured during daylight is particularly sharp. There’s plenty of detail, like road markings and license plates of other vehicles, while exposure levels are handled very well. It’s also relatively smooth – as far as dash cam footage needs to be, at least – and the 140-degree lens, while not the widest, does a perfectly decent job of capturing a good view of the road ahead.
Quality takes a dip after sunset, but that’s to be expected from any camera, let alone a dash cam. While license plate details are mostly lost, the VD1 continues to impress with practically zero grain, and road signs remain legible. Visibility fell during nighttime rainfall, and when driving on unlit roads after dark, but that’s to be expected. The fact remains that, had I been in an accident, evidence would have been captured in adequate detail.
