I recently bought a Viofo A139 Pro and I soon realised that I was not getting the same results as other people with the same camera.
@Mtz captured this image at a vehicle closing speed of ~200km/h
By comparison this is one of my best captures at 40+40 = 80mph = 130km/h
There are many factors that could explain the difference in contrast and number plate definition, including:
- Firmware version
- Bitrate / quality
- Number plate text size and background reflectivity, and cleanliness
How much difference would dull vs bright headlights make? It's not really something I can test because I'm stuck with the car I have. I have an old car (12 years, 140000 miles). Thehalogen EDIT: Xenon HID headlamps are cloudy, bad enough that they needed a polish to pass the annual roadworthy check 2 months ago. This is how they look now:
Would an upgrade to LED lights improve my dashcam performance?
Do vans, trucks, SUVs or other vehicles with higher-placed headlights have an advantage over cars?
Does the legal limit on headlight brightness & light pattern vary around the world?
