Product Features

32-Channel IP Video Recording

The NVR4232-16P-4KS3 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 12MP, allowing integration with high-resolution Dahua and compatible third-party 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 eliminates 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 160 Mbps incoming bandwidth, 128 Mbps recording bandwidth, and 60 Mbps outgoing bandwidth, allowing it to handle multiple HD and high-resolution cameras efficiently for live view, recording, and remote playback. This makes it suitable for medium-to-large CCTV installations with many cameras running simultaneously.

Smart H.265+ Compression for Storage Saving

The NVR4232-16P-4KS3 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.

AI by Recorder with SMD Plus

This recorder supports AI by Recorder with 2-channel SMD Plus, helping distinguish human and vehicle movement from irrelevant motion such as shadows, rain, leaves, or lighting changes. This improves alarm accuracy and makes event review more practical for everyday surveillance use.

AI by Camera Support for Advanced Analytics

When used with supported Dahua IP cameras, the NVR can work with advanced AI functions such as face detection, face recognition, perimeter protection, SMD, 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. It supports 4K HDMI output up to 3840 × 2160, making it suitable for security desks, offices, shops, and CCTV control rooms that require clear local viewing.

2 SATA HDD Bays for Large Storage Capacity

The NVR4232-16P-4KS3 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.
