The camera works well at night with its night vision and WDR. Low light, high contrast, or dim streets pose no problem. A user shared that the night vision caught an accident at a roundabout and provided clear evidence.
It uses a 170° wide-angle lens. The lens covers several lanes at once. This feature helps to reduce blind spots and shows more of the road.

The parking monitor keeps your car under watch when parked. It starts recording if sensors note a bump or movement. This record can capture cases of hit-and-run or vandalism in busy areas. For all-day use without draining power, you must buy a compatible hardwire kit. Many dash cams need this kit to make parking monitoring work continuously.
