Technology Introduce
1. WizColor
WizColor is Dahua’s advanced imaging technology that delivers clear, full-color nighttime video using AI-powered enhancement.
WizColor Technology
How it works: WizColor combines AI-ISP processing, a large pixel sensor, and a wide-aperture lens to capture and enhance more light at night.
Why it matters: You get bright, full-color video with sharper details and less blur in low-light conditions.
Example: Instead of grainy black-and-white footage, you see clear color details even in very dark areas.
Features of WizColor
F1.0 Large Aperture
This large-aperture F1.0 lens captures significantly more light than standard lenses, producing brighter, clearer images in low-light conditions.
The amount of incoming light of WizColor F1.0 aperture is 2.5× higher than F1.6.
Large Pixel Size Sensor
Larger pixels capture more photons, boosting the signal for brighter, clearer images with less noise.
