Hikvision DS-7732NI-M4 32CH 8K Network Video Recorder

Overview

The DS-7732NI-M4 is Hikvision's 32-channel NVR for enterprise-scale IP deployments where channel density and bandwidth headroom matter more than a small footprint. Fits standard 1.5U rack space in comms cabinets alongside switches and patch panels.

Key specs

• 32-ch IP camera inputs — one recorder covers a full site rather than splitting across multiple units
• Up to 320 Mbps incoming bandwidth — the working ceiling when budgeting camera resolutions/bitrates across all 32 channels
• Decoding up to 32-ch @ 1080p — sized for live-view walls and simultaneous playback across the full channel count
• Compression: H.265+/H.265/H.264+/H.264 — H.265+ and H.265 cut storage load versus H.264 at equivalent quality
• Up to 8-ch IP speakers — audio announcements/alerts can be integrated on top of the video feeds
• 1.5U rack-mount chassis — installs in standard equipment racks or server cabinets

Deployment notes

With 320 Mbps shared across up to 32 inputs, plan camera bitrates against total channel count before finalising the design — mixing high-resolution streams across all 32 channels will use the available bandwidth quickly. The 8-channel IP speaker support is worth specifying where audio warning/notification is part of the brief, such as warehouses or industrial sites.

Suited to commercial buildings, warehouses, retail estates and industrial sites needing centralised recording across a large camera count rather than multiple smaller NVRs.
