32-Channel IP Camera Recording

The Dahua NVR-NV44A32-EI supports up to 32 compatible IP security cameras, making it suitable for larger surveillance installations.

It provides centralized recording and management for multiple monitoring locations, including:

• Commercial buildings
• Warehouses
• Retail stores
• Office complexes
• Industrial facilities
• Parking areas
• Multi-camera security installations

The maximum supported camera recording resolution should be confirmed against the manufacturer’s technical specifications.

Four HDD Bays for Local Video Storage

The Dahua NVR-NV44A32-EI features four HDD bays for installing compatible surveillance hard drives.

Multiple drive bays provide flexibility when configuring local video storage for larger camera systems.

Recording duration depends on:

• Number of connected cameras
• Camera resolution
• Video bitrate
• Frame rate
• Compression format
• Recording schedule
• Installed hard drive capacity

Important: The supplied information identifies four HDD bays but does not confirm the maximum supported capacity per drive or whether hard drives are included.

256Mbps Network Bandwidth

The NVR supports up to 256Mbps for access, storage or forwarding, according to the supplied specifications.

When the specified AI functionality is enabled, the bandwidth limit is 180Mbps.

This is an important consideration when designing systems with multiple high-resolution IP cameras.

Actual performance depends on camera bitrates, recording settings and enabled AI functions.

Smart H.265+ Video Compression

The Dahua NVR supports the following video formats:

• Smart H.265+
• H.265
• Smart H.264+
• H.264
• MJPEG

These compression technologies help manage video storage and network bandwidth.

Smart compression can reduce storage requirements when supported by the connected cameras and configured recording settings.

Actual storage savings depend on video content and system configuration.

Adaptive Video Decoding

The recorder supports adaptive decoding with a maximum specified decoding capability of 16 × 1080p at 30 fps.

This specification describes decoding performance and does not reduce the recorder’s 32-channel camera capacity.

Built-In AI Face Detection and Recognition

The Dahua NVR-NV44A32-EI supports one channel of NVR-based face detection and recognition.

This allows the recorder to process supported face analytics without relying exclusively on camera-based AI processing.

Available functions depend on firmware, configuration and connected camera compatibility.

Face Database Management

The NVR supports:

• Up to 10 face databases
• Up to 20,000 face images in total

These capabilities support specialized face recognition applications where appropriately configured and legally permitted.

Face recognition deployments should comply with applicable privacy laws, consent requirements and organizational policies.

Built-In AI Perimeter Protection

The recorder supports two channels of NVR-based perimeter protection.

These functions can help monitor designated security areas for supported intrusion and boundary-crossing events.

Detection performance depends on scene conditions and system configuration.

Built-In SMD Plus Intelligent Motion Detection

The NVR supports four channels of NVR-based SMD Plus.

SMD Plus is Dahua’s intelligent motion detection technology, designed to improve the usefulness of motion events through supported classification functions.

The available detection capabilities depend on system configuration and firmware.

Advanced AI Analytics by Camera

In addition to its built-in AI functions, the Dahua NVR-NV44A32-EI supports analytics generated by compatible IP cameras.

Supported camera-based analytics include:

Face Detection and Recognition

Supports compatible camera-generated face detection and recognition events.

Perimeter Protection

Supports compatible intelligent perimeter monitoring.

SMD Plus

Supports intelligent motion detection events from compatible cameras.

ANPR

Supports automatic number plate recognition data generated by compatible cameras.

People Counting

Supports people-counting analytics from compatible cameras.

Stereo Analysis

Supports stereo analysis functions provided by compatible cameras.

Heat Map

Supports camera-generated heat map analytics.

Important: Camera-based AI functions require compatible IP cameras. Feature availability and supported channel counts depend on camera models and system configuration.

Third-Party Network Camera Compatibility

The Dahua NVR-NV44A32-EI supports connection to compatible third-party IP cameras.

This provides flexibility for installations using network cameras from different manufacturers.

Compatibility should be confirmed before installation, particularly for advanced AI analytics, audio and camera management functions.

1.5U Chassis Design

The NVR features a 1.5U chassis, providing a larger form factor for multi-camera recording applications.

Installation requirements, mounting accessories and rack compatibility should be confirmed before deployment.
