Dahua DHI-NVR4232-4KS3 32-Channel 4K Lite NVR

Dahua NVR4232-4KS3

The Dahua 32-Channel Lite recorder targets installations that already use managed PoE switches or fiber uplinks. This non-PoE 1U NVR accepts 32 IP camera streams at up to 12MP resolution. A Gigabit Ethernet port connects to your existing LAN infrastructure. Embedded Linux firmware runs the recording engine without third-party operating system licensing. Dual SATA bays hold surveillance drives up to 20 TB each for multi-week retention at high bitrates. HDMI and VGA outputs support operator workstations and auxiliary spot monitors.

Two USB ports handle mouse input, export, and maintenance tasks. Motion detection rules trigger recording and notification events across all configured channels. The Lite series chassis keeps rack depth and power draw modest for branch offices and remote sites. Network engineers pair this model with enterprise switches when centralized PoE budgeting and VLAN segmentation are required. Procurement teams choose it when camera power is handled upstream and only recording capacity is needed at the rack. All 32 channels activate without add-on decoder hardware. Bitrate throttling and sub-stream recording help balance quality against disk consumption. Firmware updates apply through the web interface or USB recovery path. The recorder integrates with Dahua VMS clients for centralized multi-site management over secure connections.

  • Supports VLAN tagging through connected managed switches

• Up to 12MP Recording
  Captures 4K and high-megapixel streams from current-generation IP cameras.

• Dual SATA Storage Bays

  • Two SATA III interfaces support drives up to 20 TB per bay
  • Handles continuous write loads from 32 simultaneous channels
  • RAID and overwrite policies configurable per site requirements

• Dual Monitor Outputs
  HDMI and VGA connectors drive independent live-view displays.

• Motion Event Triggers
  Zone-based motion rules reduce storage consumption during low-activity periods.

• Lite Series Efficiency

Why Choose NVR4232-4KS3

• Separates recording from PoE switching so network teams control VLANs and power budgets on existing gear.

• 32-channel density in 1U reduces rack space compared with multiple smaller recorders.

• 12MP headroom supports camera upgrades without replacing the recorder.

• Embedded Linux firmware minimizes OS patching overhead for security-conscious sites.

• Dual 20 TB SATA capacity addresses long retention requirements for audit and incident review.

• Gigabit uplink integrates cleanly with core switching in campus and warehouse networks.
