Dahua DHI-NVR4232-16P-EI  Specifications

 32-Channel IP Camera Support

Connect and manage up to 32 compatible IP cameras from one central recording system. This allows comprehensive monitoring of entrances, corridors, parking areas, offices, and other important locations. Multiple viewing layouts help security teams monitor different areas efficiently.

16 Built-In PoE Ports

The recorder has 16 integrated PoE ports for directly connecting compatible IP cameras. Each camera can receive power and transmit video through one Ethernet cable, simplifying installation and reducing the need for separate power supplies. The total PoE power budget is 130 W, with up to 25.5 W available per port, subject to the overall power limit.

Advanced WizSense AI Technology

WizSense uses intelligent video analytics to help identify relevant security events and reduce unnecessary alerts. Recorder-based functions include face detection, face recognition, perimeter protection, and Smart Motion Detection Plus. These capabilities help security personnel identify potential threats and investigate incidents more efficiently.

Smart H.265+ Video Compression

Smart H.265+ reduces video file sizes while maintaining useful image detail. This helps conserve hard drive space and reduces the bandwidth required to transmit camera footage. It is particularly useful when recording multiple high-resolution cameras continuously.

Support for Cameras up to 16 MP

The recorder supports compatible IP cameras with resolutions of up to 16 megapixels. This provides flexibility for surveillance systems that require detailed images for monitoring and incident review. Actual performance depends on the combined camera bandwidth, recording settings, and decoding capacity.

Dual Hard Drive Storage

Two SATA drive bays allow the NVR to accommodate up to two compatible hard drives, each supporting up to 20 TB according to the manufacturer’s product page. This provides flexible storage for extended recording retention and large surveillance deployments. Hard drives are generally sold separately, and retention time depends on camera resolution, frame rate, and recording configuration.

4K HDMI and VGA Outputs

The HDMI output supports resolutions up to 3840 × 2160, allowing connection to a compatible 4K monitor. VGA output provides an additional display option for compatible monitors. These connections support convenient local viewing and surveillance management.

High-Bandwidth Recording Performance

The recorder supports up to 256 Mbps incoming, recording, and outgoing bandwidth when AI is disabled. With AI enabled, the specified bandwidth is up to 180 Mbps for each of these functions. This capacity helps manage numerous camera streams, although the actual decoding performance depends on whether AI features are active.
