· Software Detection: motion detection, people detection, virtual line crossing, zone intrusion, area exit.

· Built-in Microphone.

· WDR 120 dB: eliminates the impact of varying lighting contrasts on image quality.

· 3D DNR: spatial noise reduction.

· Corridor Mode: shooting in vertical resolution.

· Defog: increases contrast to eliminate blurriness caused by fog or smoke.

· BLC: backlight compensation.

· HLC: local light masking.

· Day/Night Mode with ICR: switches to infrared sensitivity in the dark by moving the IR filter away when illumination is sufficient.

· Compression Formats: H.264, H.265, H.264+, H.265+.
