IR illumination with a range of 20 meters.

WDR 120 dB — mitigates the impact of lighting variations on image quality.

3D DNR — reduces spatial noise.

Defog — clears up foggy or smoky scenes.

BLC — compensates for backlighting.

HLC — masks bright areas to improve visibility.

Day/Night mode with ICR: switches to black and white mode in low light, enhancing sensitivity by mechanically adjusting the IR filter away from the sensor.
