Hikvision 32-Channel AcuSense PoE 4K Network Video Recorder

Description

Hikvision DS-7732NXI-I4/16P/S 32-channel AcuSense NVR for larger IP CCTV systems

The Hikvision DS-7732NXI-I4/16P/S is a 32-channel network video recorder designed for commercial, industrial and larger residential IP surveillance systems. Sixteen integrated PoE ports simplify direct camera connection, while the recorder can manage up to 32 IP camera channels in total.

AcuSense analytics help focus attention on people and vehicles rather than routine movement, while 256 Mbps incoming bandwidth, four SATA interfaces and 4K HDMI output give the recorder the capacity needed for larger multi-camera installations.

Is This Right for You?

This NVR is a strong choice when you need more than a typical 8- or 16-camera recorder, but still want built-in PoE for a substantial part of the system. It is particularly useful for offices, retail premises, warehouses, multi-building properties and other sites where recording capacity and intelligent event filtering matter.

The recorder supports 32 IP camera channels but provides 16 built-in PoE ports. If you intend to use more than 16 PoE cameras, the additional cameras will need to connect through the network using suitable external PoE switching or other compatible power arrangements.

Why Choose This Product?

• 32 IP camera channels: provides capacity for larger surveillance systems without requiring a second recorder simply to expand beyond 16 cameras.
• 16 built-in PoE ports: connect and power compatible PoE cameras directly from the recorder, with IEEE 802.3af/at support and up to 200 W total PoE power.
• AcuSense perimeter protection: supports human and vehicle classification on up to four channels to help reduce nuisance alarms from irrelevant movement.
• Motion Detection 2.0: recorder-side analysis is supported across up to 32 channels for more useful event searching and notification.
• Facial analytics: supports up to one-channel human face capture and up to four-channel face-picture comparison on this revision.
• Flexible recording storage: four SATA interfaces support up to 16 TB per drive, plus an eSATA interface for additional storage options.
• Efficient video compression: H.265+, H.265, H.264+ and H.264 support helps reduce storage and network requirements.
• High-resolution local display: HDMI 1 supports output up to 3840 × 2160 at 60 Hz for detailed monitoring on a compatible 4K display.

Before You Buy

• The DS-7732NXI-I4/16P/S supports up to 32 IP camera channels but has 16 built-in PoE camera ports.
• Additional cameras beyond the 16 direct PoE connections require suitable network connectivity and, where required, separate PoE power.
• Hard drives are not included in the confirmed package contents and must be selected separately.
• Four SATA interfaces are available, with current Hikvision documentation specifying support for drives up to 16 TB each.
• The PoE interfaces support IEEE 802.3af/at with a combined PoE power budget of up to 200 W. Check individual camera power requirements when planning the system.
• The recorder operates from 100–240 V AC, 50–60 Hz mains power.

Storage Guide – Choosing the Right Hard Drive

The amount of storage you need depends on the number of cameras, camera resolution, recording schedule, and how long you want to keep your footage.

Quick Reference

Suggested starting capacities for typical CCTV systems:

Choose a larger drive when recording continuously, using high-resolution cameras, or keeping footage for longer periods.

Consider More Storage If You:

• Record continuously, 24 hours a day
• Use 4MP, 6MP, or 8MP/4K cameras
• Need to retain footage for 30 days or longer
• Have busy areas with frequent movement
• Record audio together with video
• Plan to add more cameras later
