DS-7732NXI-I4/16P/S_C

The commercial 32-channel NVR with integrated PoE

The Hikvision DS-7732NXI-I4/16P/S is the recorder we install at the upper end of small-to-medium commercial sites. 32 channels of camera capacity. Four SATA bays with RAID support. Built-in 16-port PoE switch handling the local cameras, with the remaining 16 channels handled by a separate PoE switch or directly over the IP network. Commercial-grade everything.

This is the NVR for security estates with multiple boom gates and communal coverage areas, retail centres with comprehensive customer-flow and stockroom monitoring, warehouse complexes with extensive perimeter and interior coverage, and small commercial sites that have grown past the 16-channel capacity of the residential-grade units.

What this NVR is actually good at

• 32 channels of IP camera capacity. Up to 12MP per camera.
• Built-in 16-port PoE switch. Local cameras connect directly. Additional 16 channels via separate switch or networked cameras.
• 4 SATA bays up to 16TB per drive. Up to 64TB raw capacity.
• RAID 0, 1, 5, 6, 10 support. Drive-failure-resilient storage.
• AcuSense+ analytics. Enhanced AI capabilities including line crossing, intrusion detection, and people counting across all 32 channels.
• Hot-swappable drive bays. Drive replacement without system downtime.
• Dual gigabit network ports. Redundancy or network separation.
• Multi-user access with granular role-based permissions.
• Alarm I/O terminals. Integration with multi-zone alarm systems.

If you want different capacity or features

• The DS-7732NXI-I4/S is the same 32-channel commercial-grade unit without built-in PoE. Useful when external PoE infrastructure is already in place.
• The DS-7732NXI-I4/VPro is the 32-channel option with enhanced AI capabilities for sites needing facial recognition or advanced analytics.
• The DS-7764NI-M4 doubles to 64 channels for the largest installations.
• The DS-9664NXI-I8/S is the flagship 64-channel unit with 8-bay storage.

Camera pairings

32-channel installations typically include a varied camera mix: AcuSense bullets like the DS-2CD2T46G2H-4I on perimeter, ColorVu identification cameras like the DS-2CD2086G2H-I 8MP at access points, dome cameras for indoor coverage, PTZ cameras for large open areas, and LPR cameras for vehicle access logging. Our installation guide covers complete commercial system design.

Specialist installation for serious sites

32-channel commercial sites require proper design: network architecture, IP addressing schemes, switch sizing, redundancy planning, multi-user permission structures, and integration with existing site infrastructure. We do that design and installation work across Pretoria East, Centurion, Midrand, and Johannesburg. Larger sites are scoped during a free site inspection. Contact us to arrange a commercial visit.
