How to Choose Dash Cams for:
Reading license plates at high speed(According to Reddit)
Who is this for?
Drivers concerned about hit-and-runs or insurance fraud where identifying the other vehicle is the top priority.
Unique demands
Most dash cams record 'good' video, but very few have the sensor quality and processing power to freeze a frame and clearly read a license plate on a car traveling 60mph at night.
- High resolution (4K or 2K)
- Advanced image sensor (Sony STARVIS 2)
- High bitrate recording
- HDR (High Dynamic Range) to handle glare and shadows
Prioritize
Sony STARVIS 2 sensor: Specifically designed to capture clear details in high-contrast and low-light scenarios.
CPL (Circular Polarizing Lens) filters: Reduces dashboard reflections and windshield glare that can obscure plates.
High frame rate (60fps): Reduces motion blur for vehicles moving at high speeds.
Deprioritize
Basic 1080p sensors: Standard resolution often blurs license plates on moving vehicles or in low light.
Extreme wide-angle lenses: Ultra-wide lenses (170°+) can distort the image and reduce the pixel density available for identifying small text like plate numbers.
