· Motion detection, face detection, human detection, line crossing detection, area entrance and exit detection, loitering detection, vehicle detection, people counting.

· IR illumination with a range of 40 meters.

· WDR 120 dB — eliminates the impact of varying light levels on image quality.

· 3D DNR — spatial noise reduction.

· Defog — software-based removal of blur caused by fog or smoke.

· BLC — backlight compensation.

· HLC — masking of local light sources.

· Day/night mode with ICR: in sufficient light, the filter blocks IR rays to optimize color rendering, and in darkness, it mechanically moves away from the sensor to increase sensitivity.

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

· Streaming speed — 25 fps with WDR off, 25 fps with WDR on. Bitrate — 8 Mbps.

· Built-in microphone.

· Cold start.
