4-Channel IP Security Camera Recording

The Dahua NVR-NV41A04-P4-4K-S2L is designed for installations requiring up to four IP cameras.

It provides a centralized recording platform for monitoring multiple locations, such as:

• Residential entrances
• Driveways
• Retail stores
• Offices
• Commercial entrances
• Small warehouses

The supported maximum camera recording resolution was not specified in the supplied product information.

Four Integrated PoE Ports

The NVR features four built-in PoE ports for connecting compatible IP cameras.

Power over Ethernet allows supported cameras to receive electrical power and network connectivity through Ethernet cabling.

Benefits include simplified installation, fewer separate power adapters and centralized camera connections.

The total PoE power budget and individual port limits should be confirmed before installation.

4K HDMI and VGA Video Output

The Dahua NVR supports simultaneous HDMI and VGA video output.

Its HDMI output supports display resolutions up to 4K Ultra HD, allowing connection to compatible 4K security monitors.

Note: 4K HDMI output does not automatically confirm that every connected camera can record at 4K resolution. Maximum camera recording resolution must be verified separately.

Smart H.265+ Video Compression

The NVR supports:

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

These compression formats help manage recording storage and network bandwidth.

The recorder also supports H.265 automatic switching, as specified by the supplier.

Actual compression efficiency depends on connected cameras, video settings and scene activity.

AI Security Analytics by Camera

The Dahua NVR supports intelligent analytics generated by compatible network cameras.

Supported camera-based functions include:

Face Detection

Supports face detection events generated by compatible cameras.

Perimeter Protection

Supports intelligent perimeter monitoring functions provided by compatible cameras.

IVS – Intelligent Video Surveillance

Supports compatible intelligent video surveillance events.

People Counting

Supports people-counting data generated by compatible cameras.

Heat Map

Supports compatible camera-generated heat map analytics.

SMD – Smart Motion Detection

Supports intelligent motion detection events from compatible cameras.

Important: These functions are specified as AI by Camera. The connected IP camera must support the relevant analytics. The supplier has not confirmed independent AI processing by the NVR.

ONVIF and RTSP Camera Compatibility

The recorder supports mainstream IP security cameras using compatible ONVIF and RTSP protocols.

This provides flexibility when integrating supported third-party network cameras.

Advanced features such as AI detection, audio and remote camera management may vary depending on the connected camera model.

P2P Remote Surveillance

The Dahua NVR supports P2P remote surveillance and mobile video playback.

With appropriate network configuration, users can access supported video monitoring functions from compatible mobile devices.

The specific mobile application and available remote features should be confirmed for this model and firmware version.

Remote IP Camera Management

The NVR supports remote configuration and management of compatible IP cameras.

Supported functions include:

• Camera parameter configuration
• Device information retrieval
• Remote camera administration
• Batch firmware upgrades for supported cameras of the same model

Available functions depend on camera compatibility.

Compact 1U Design

The compact 1U form factor makes the recorder suitable for space-conscious security installations.

It is designed for applications where a full-size recorder is unnecessary.
