Hikvision DS-7732NXI-I4/16P/VPro 32 Channel 16 PoE AcuSeek 32MP 4 HDD NVR The Hikvision DS-7732NXI-I4/16P/VPro is a high-performance 32 channel Network Video Recorder (NVR) from Hikvision's advanced I/VPro series. Designed for demanding professional IP CCTV systems, it combines AcuSeek, AcuSearch and advanced AI analytics with ultra-high-resolution recording, powerful decoding performance and substantial internal storage capacity. The recorder supports up to 32 IP camera channels and includes 16 built-in PoE ports for directly connecting compatible IP cameras. It also provides up to 384Mbps incoming bandwidth, 256Mbps outgoing bandwidth and recording resolutions up to 32MP, making it suitable for larger commercial and industrial surveillance systems. AcuSeek Intelligent Video Search The DS-7732NXI-I4/16P/VPro features Hikvision's advanced AcuSeek technology, designed to make recorded CCTV footage faster and easier to investigate. When used with compatible Hikvision AcuSense cameras with AcuSearch enabled, the recorder supports AcuSeek across all 32 channels and can model up to 300,000 targets per day. This can dramatically reduce the time required to locate relevant people, vehicles and events within large amounts of recorded footage. AcuSearch Human & Vehicle Search Hikvision AcuSearch allows operators to rapidly locate human and vehicle targets within recorded footage instead of manually reviewing hours of video. With compatible cameras and the required functions enabled, AcuSearch can operate across all 32 channels and supports modelling up to 300,000 targets per day, making this NVR particularly well suited to larger professional security installations.

Up to 16 compatible cameras can connect directly to the recorder using the integrated PoE ports, while additional network cameras can be connected through the local network. 16 Built-In PoE Ports The recorder features 16 integrated Power over Ethernet (PoE) interfaces, allowing compatible IP cameras to receive both power and network connectivity through a single Ethernet cable. The built-in PoE switch supports IEEE 802.3af/at and provides a total power budget of up to 200W, helping simplify installation and reduce the requirement for separate camera power supplies or external PoE switches. Up to 32MP Recording Resolution The DS-7732NXI-I4/16P/VPro supports recording resolutions up to 32 megapixels, making it suitable for Hikvision's latest ultra-high-resolution IP cameras. Supported recording resolutions include 32MP, 24MP, 12MP, 8MP, 7MP, 6MP, 5MP, 4MP, 3MP and 1080p, providing excellent flexibility when designing mixed-resolution CCTV systems. 384Mbps Incoming Bandwidth With up to 384Mbps incoming bandwidth, the DS-7732NXI-I4/16P/VPro can handle large numbers of high-resolution camera streams simultaneously. Its 256Mbps outgoing bandwidth also provides strong performance for live viewing, playback and remote access in demanding professional environments. Four HDD Bays – Up to 80TB Raw Storage The recorder includes 4 SATA interfaces for internal surveillance hard drives, with each drive bay supporting a disk capacity of up to 20TB. This provides a potential total raw storage capacity of up to 80TB, making the DS-7732NXI-I4/16P/VPro particularly suitable for installations requiring long recording retention periods or multiple high-resolution cameras. Actual recording duration will depend on camera resolution, frame rate, compression settings, recording schedule, scene activity and installed hard drive capacity. Dual HDMI & 4K Video Output The DS-7732NXI-I4/16P/VPro includes two HDMI outputs. HDMI 1 supports resolutions up to 4K UHD (3840 × 2160) at 30Hz, while HDMI 2 supports resolutions up to 1080p. A VGA output is also provided, with independent HDMI and VGA operation offering additional flexibility for local monitoring and control-room installations. Powerful 32-Channel Decoding The DS-7732NXI-I4/16P/VPro provides strong multi-camera decoding performance. With NVR AI functions disabled, it supports up to 32 channels of 1080p video at 30fps. With NVR AI functions enabled, decoding performance supports up to 20 channels of 1080p video at 30fps. Advanced Facial Recognition The recorder supports professional facial recognition functions including human face capture, face picture comparison and face picture search. Up to 16 face picture libraries can be configured with up to 50,000 face pictures in total. Face picture comparison is supported on up to 8 channels. ANPR & Advanced AI Analytics When paired with compatible Hikvision cameras, the DS-7732NXI-I4/16P/VPro can support advanced functions including ANPR, perimeter protection, video structuralisation, Motion Detection 2.0, people counting and other Video Content Analytics events. These capabilities make the recorder suitable for more complex security systems where intelligent video analysis is required in addition to conventional recording. H.265+ Video Compression Hikvision's H.265+ video compression helps significantly reduce storage space and bandwidth requirements compared with older compression formats. Hikvision states that H.265+ can reduce required storage capacity by up to 75%, helping extend CCTV recording retention and make more efficient use of installed hard drives.
