4MP High-Definition Video Resolution

The Dahua N43BU82 captures video at 2688 × 1520 resolution, providing detailed surveillance footage for monitoring entrances, driveways, parking areas and commercial properties.

Its 4MP resolution offers improved image detail compared with standard 1080p security cameras.

This can help users review important events and identify visible details in recorded footage.

Smart Dual Illumination – IR and Warm Light

The Dahua N43BU82 features Smart Dual Illumination, combining infrared and warm-light illumination.

This technology provides flexible nighttime monitoring by supporting infrared operation and warm-light illumination according to the camera’s configuration.

The specified illumination range is up to 30 metres (approximately 98 feet).

Actual nighttime performance depends on lighting conditions, camera positioning and scene characteristics.

Full-Color Night Vision

The camera supports full-color night vision using its warm-light illumination capabilities.

This allows the camera to capture color details in suitable low-light conditions.

Color nighttime footage can help distinguish clothing, vehicles and other visible objects more effectively than monochrome footage under comparable conditions.

In infrared mode, nighttime footage may appear in black and white.

AI Human and Vehicle Detection

The Dahua N43BU82 supports intelligent detection of humans and vehicles.

These capabilities help users focus on relevant security activity instead of relying solely on basic motion detection.

The camera can be configured for supported detection events according to its available settings.

SMD 4.0 Smart Motion Detection

The camera features SMD 4.0, Dahua’s smart motion detection technology.

SMD 4.0 uses intelligent classification to help distinguish people and vehicles from other movement within the monitored scene.

This can help reduce unnecessary motion alerts caused by certain environmental activity.

Detection performance depends on installation conditions and camera configuration.

AI Perimeter Protection

The Dahua N43BU82 supports AI perimeter protection for monitoring designated security areas.

Compatible detection rules can help identify relevant activity around entrances, boundaries and other monitored locations.

The exact supported perimeter rules should be confirmed against the camera’s technical documentation.

Active Deterrence – Red and Blue Warning Lights

The camera features integrated red and blue warning lights designed to provide a visible deterrent during supported security events.

These lights can help draw attention to activity occurring within the monitored area.

Warning-light behaviour and activation options depend on camera configuration.

Built-In Siren for Audible Deterrence

The Dahua N43BU82 includes a built-in siren for active deterrence.

When configured for supported events, the audible warning can help discourage unwanted activity.

The siren’s sound level and available alert modes were not specified in the supplied product information.

Two-Way Audio with Dual Microphones and Speaker

The camera features:

• Built-in dual microphones
• Built-in speaker
• Two-way audio capability

Two-way audio allows users to communicate through the camera using compatible viewing software or recording equipment.

This can be useful for speaking with visitors, delivery personnel or individuals near monitored entrances.

Remote two-way audio functionality depends on compatible software, network connectivity and system configuration.

H.265 Video Compression

The Dahua N43BU82 supports H.265 video compression.

H.265 helps manage video storage requirements and network bandwidth compared with older compression technologies under suitable conditions.

Actual storage savings depend on video settings, scene activity and recording configuration.

IP67 Weatherproof Outdoor Design

The camera features an IP67-rated housing, designed to provide protection against dust and water ingress under the rating’s specified test conditions.

This makes it suitable for many outdoor surveillance applications.

Proper installation, weatherproof cable connections and suitable mounting accessories remain important for outdoor reliability.

Power over Ethernet (PoE)

The Dahua N43BU82 supports PoE connectivity, allowing compatible network equipment to provide power and data through Ethernet cabling.

Benefits include:

• Simplified camera installation
• Reduced need for separate power adapters
• Convenient network connectivity
• Compatibility with suitable PoE switches and NVRs

The exact PoE standard and maximum power consumption should be confirmed before installation.
