Hikvision DS-7732NXI-I4/S 32-Channel AcuSense 4K NVR
The Hikvision DS-7732NXI-I4/S is a powerful 32-channel network video recorder designed for professional IP CCTV systems that require intelligent analytics, high-resolution recording, and large storage capacity. Built for commercial, industrial, retail, warehouse, estate, school, office, and advanced residential surveillance installations, this NVR provides a strong recording platform for larger security systems.
With support for up to 32 IP camera inputs and 256Mbps incoming bandwidth, the DS-7732NXI-I4/S is suitable for multi-camera IP surveillance setups using high-resolution cameras. It supports efficient video compression formats including H.265+, helping reduce bandwidth and storage usage while maintaining clear video quality.
Hikvision AcuSense technology helps improve event accuracy by using intelligent analytics to focus on relevant human and vehicle activity. This helps reduce false alarms caused by irrelevant movement such as rain, leaves, animals, shadows, or lighting changes. The NVR also supports advanced analytics such as facial recognition, perimeter protection, Motion Detection 2.0, ANPR, people counting, and video structuralisation when used with compatible Hikvision cameras.
The DS-7732NXI-I4/S includes dual HDMI outputs with up to 4K display resolution, VGA and CVBS output options, 4 SATA interfaces for hard drive installation, eSATA support, dual Gigabit LAN ports, alarm input/output connections, two-way audio, and USB interfaces for backup and control. Its rack-mountable design makes it ideal for professional CCTV cabinets and control room installations.
