Hikvision DS-7732NXI-K4/16P/VPro 32 Channel 16 PoE AcuSeek 12MP 4 HDD NVR The Hikvision DS-7732NXI-K4/16P/VPro is a professional 32 channel Network Video Recorder (NVR) from Hikvision's VPro series, designed for larger IP CCTV installations requiring high camera capacity, intelligent video analytics and substantial internal storage. Featuring 16 built-in PoE ports, the recorder allows compatible IP cameras to connect directly for both network data and power, while additional cameras can be added over the network to provide support for up to 32 IP camera channels. With up to 256Mbps incoming bandwidth, recording resolutions up to 12MP and advanced Hikvision AI functions, the DS-7732NXI-K4/16P/VPro is ideal for demanding commercial and professional surveillance systems. AcuSeek Intelligent Video Search The DS-7732NXI-K4/16P/VPro features Hikvision's advanced AcuSeek technology, designed to make CCTV investigations faster and more efficient. When used with compatible Hikvision AcuSense cameras with AcuSearch enabled, AcuSeek can operate across up to 32 channels. The system is capable of modelling up to 50,000 targets per day, helping operators quickly locate relevant people, vehicles and events without manually reviewing large amounts of recorded footage. AcuSearch Human & Vehicle Search Hikvision AcuSearch provides fast searching of recorded footage for specific human and vehicle targets. This can dramatically reduce investigation time in larger CCTV systems and is particularly useful for retail premises, warehouses, logistics facilities, offices, schools, factories and car parks.

Up to 16 compatible cameras can connect directly to the recorder's integrated PoE interfaces, while additional IP cameras can be connected over the network. 16 Built-In PoE Ports The recorder features 16 integrated Power over Ethernet (PoE) interfaces, allowing compatible IP cameras to receive both data connectivity and electrical power through a single network 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 external PoE switches. 256Mbps Incoming Bandwidth With up to 256Mbps incoming bandwidth, the DS-7732NXI-K4/16P/VPro is designed to handle multiple high-resolution IP camera streams simultaneously. This additional network capacity makes it particularly suitable for larger systems combining multiple high-resolution cameras and demanding recording requirements. Four HDD Bays – Up to 64TB Raw Storage The DS-7732NXI-K4/16P/VPro includes 4 SATA interfaces for internal surveillance hard drives. Each SATA interface supports an HDD capacity of up to 16TB. This provides a potential total raw storage capacity of up to 64TB, making the recorder particularly suitable for CCTV systems requiring longer recording retention periods. Actual recording duration depends on camera resolution, frame rate, compression settings, recording schedule, scene activity and installed hard drive capacity. Up to 12MP Recording Resolution The Hikvision DS-7732NXI-K4/16P/VPro supports recording resolutions up to 12 megapixels, allowing it to be used with modern high-resolution Hikvision IP cameras. Supported resolutions include 12MP, 8MP, 6MP, 5MP, 4MP, 3MP and 1080p, providing flexibility when designing mixed-resolution CCTV systems. 4K Ultra HD HDMI Output The recorder's HDMI output supports resolutions up to 4K UHD (3840 × 2160) at 30Hz, allowing high-resolution surveillance footage to be displayed on a compatible 4K monitor or television. Independent HDMI and VGA outputs provide additional flexibility for local monitoring and control-room installations. Powerful Multi-Channel Decoding With NVR-based AI functions disabled, the DS-7732NXI-K4/16P/VPro can decode up to 24 channels of 1080p video at 30fps. With AI functions enabled, the recorder supports decoding up to 12 channels of 1080p video at 30fps, providing strong performance for multi-camera live viewing and playback. Hikvision AcuSense Human & Vehicle Detection Hikvision AcuSense technology can distinguish human and vehicle activity from other forms of movement, helping reduce unwanted alarms and making recorded events easier to investigate. This intelligent classification can help security operators concentrate on events that are more likely to require attention rather than spending time reviewing irrelevant movement. Perimeter Protection The DS-7732NXI-K4/16P/VPro supports intelligent perimeter protection with human and vehicle recognition to help reduce false alarms. Compatible camera-based perimeter analytics can also be used across supported channels, providing greater flexibility when designing intelligent surveillance systems. Motion Detection 2.0 Motion Detection 2.0 provides intelligent human and vehicle classification for recorded events, helping make searches more accurate and reducing irrelevant motion alerts. NVR-based Motion Detection 2.0 is supported across all channels at up to 4MP, or up to 8MP when enhanced SVC mode is enabled. Facial Recognition The recorder supports advanced facial recognition functionality including face capture, face picture comparison and face picture search. Up to 16 face picture libraries can be configured with a total of up to 50,000 face images, while face picture comparison is supported on up to 8 channels. Professional Alarm Connectivity The DS-7732NXI-K4/16P/VPro provides 16 alarm inputs and 4 alarm outputs, allowing integration with compatible external alarm and security equipment. It also features 2 RS-485 interfaces and 1 RS-232 interface for additional professional integration requirements. H.265+ Video Compression Hikvision's H.265+ compression technology helps reduce the amount of storage space and network bandwidth required by recorded CCTV footage. Efficient compression can provide longer recording retention from installed hard drives while maintaining the image quality required for effective surveillance.
