The Hikvision DS-7732NXI-I4/16P/VPro is a 32-channel AcuSeekWhat is Hikvision AcuSeek NVR powered by Hikvision's Guanlan Large-Scale AI Models — on-NVR natural-language video search for the mid-range I-tier. Search recorded footage using everyday English (“red car near loading bay”, “person in white shirt after 4pm”) and AcuSeek surfaces matching clips in seconds. Two parallel AI engines (one for face + AcuSearch, one for AcuSeek) model up to 300,000 targets/day.

Full 32-channel AcuSearch + AcuSeek coverage, 8-ch facial recognition (16 face libraries × 50,000 faces total), ANPR on all channels. 4 × hot-plug SATA bays for HDDs up to 20 TB each (80 TB total raw). Built-in 16-port PoE switch (IEEE 802.3af/at, ≤ 200 W). Incoming 384 Mbps / outgoing 256 Mbps. DecodingWhat is Decoding Capability 20-ch @ 1080p (AI on) or 32-ch @ 1080p (AI off). dual HDMI (4K + 1080p) + VGA outputs.
