Product Features

32-Channel IP Video Recording

The NVR4232-16P-EI supports 32 IP camera channels, making it suitable for larger surveillance installations such as office blocks, schools, supermarkets, warehouses, apartment compounds, hotels, and commercial properties. It supports IP camera resolutions up to 16MP, allowing integration with high-resolution Dahua and compatible third-party IP cameras.

16 Built-In PoE Ports for Easy Camera Connection

This model comes with 16 built-in PoE ports that allow compatible IP cameras to receive both power and network connectivity directly from the NVR through a single Ethernet cable. This simplifies installation, reduces cabling costs, and removes the need for a separate PoE switch in many deployments. The total PoE power budget is 130W, with up to 25.5W per port.

High Bandwidth for Smooth Multi-Camera Recording

The recorder provides up to 256 Mbps incoming, recording, and outgoing bandwidth, allowing it to handle multiple HD and high-resolution cameras efficiently for live view, recording, and remote playback. When AI functions are enabled, Dahua lists 180 Mbps access, storage, or forwarding bandwidth for the AI-enabled mode.

Smart H.265+ Compression for Storage Saving

The NVR4232-16P-EI supports Smart H.265+, H.265, Smart H.264+, H.264, and MJPEG decoding formats, helping reduce storage consumption and bandwidth usage while maintaining good video quality. This is useful for users who want longer recording retention without excessive hard drive requirements.

WizSense AI by Recorder

This recorder supports AI by NVR, including 1-channel face detection and recognition, 2-channel perimeter protection, and 4-channel SMD / SMD Plus, helping distinguish human and vehicle movement from irrelevant motion while also enabling smarter search and access control use cases. It supports up to 10 face databases and 20,000 face images for face recognition applications.

AI by Camera Support for Advanced Analytics

When used with supported Dahua AI cameras, the NVR can work with advanced AI functions such as face detection and recognition, perimeter protection, SMD Plus, people counting, stereo analysis, and heat map. This allows users to build a more intelligent surveillance system while keeping the recorder as the central platform.

HDMI and VGA Video Output

The recorder includes 1 HDMI port and 1 VGA port for connection to a monitor or display for live view, playback, and local system management. This makes it suitable for security desks, offices, shops, schools, and CCTV control rooms that require clear local monitoring.

2 SATA HDD Bays for Large Storage Capacity

The NVR4232-16P-EI includes 2 SATA hard drive bays and supports up to 20TB per HDD, providing large storage capacity for continuous or motion-based recording depending on the number of cameras, recording settings, and retention requirements.

Compact 1U Design for Rack or Desktop Installation

Built in a compact 1U chassis, this NVR is suitable for desktop or rack installation, making it practical for offices, server rooms, schools, back offices, and other CCTV control points where space-saving equipment is preferred.
