The DS-7732NXI-I4/16P/S(E) is a 1U rack-mount AcuSense network video recorder engineered for medium-to-large IP CCTV systems. It supports up to 32 IP camera inputs, integrates 16 PoE ports for direct camera power, and accepts up to four hot-plug SATA drives for local storage. The unit provides H.265+/H.265/H.264 compression, dual HDMI outputs (HDMI1 supports 4K), and advanced AI analytics (AcuSense: facial recognition, perimeter protection, ANPR, people counting). Note: some AI functions cannot be enabled simultaneously — consult the datasheet when configuring.

• Key benefits: Simplifies deployments by powering cameras directly via PoE, reduces storage with H.265+ compression, and improves event accuracy with AcuSense analytics.
• Use cases: Retail stores, schools, offices, warehouses and other installations requiring centralised recording and AI-assisted event filtering.
• Installer notes: Verify per-disk capacity and AI feature concurrency for the exact unit/firmware you supply. Hikvision documentation indicates regional/firmware differences and that the model may be discontinued — confirm warranty and firmware support with your supplier.

Technical highlights

• 32 IP channels; up to ~12 MP per channel (model/firmware dependent).
• 16 integrated PoE ports (IEEE 802.3af/at), PoE budget ≤ 200 W.
• 4 hot-plug SATA bays (plus eSATA); per-disk capacity varies by firmware/region.
• Dual HDMI outputs (HDMI1 up to 4K), multiple USB and alarm I/O ports.

Compliance & safety: Verify UKCA/CE marking and warranty/firmware support with your supplier prior to sale. Follow official installation guidelines and local regulations for electrical and CCTV installations.
