Dahua NVR4108‑8P Network Video Recorder

The Dahua NVR4108‑8P is a powerful, compact 8-channel network video recorder (NVR) equipped with integrated PoE and advanced AI capabilities. Designed for small to medium-sized surveillance setups, it brings together simplicity, high performance, and intelligent monitoring in one streamlined solution.

This NVR is ideal for office buildings, retail shops, schools, residential buildings, warehouses, and other environments that require high-definition surveillance with minimal cabling and robust remote monitoring.

Intelligent Video Recording Made Simple

With 8 built-in PoE ports, the Dahua NVR4108‑8P can connect and power up to eight IP cameras directly. This eliminates the need for separate power supplies and drastically reduces installation complexity and wiring costs.

The NVR supports resolutions of up to 8MP (4K) and provides smooth, reliable performance for both live viewing and playback. Whether it’s identifying details in high-traffic areas or reviewing footage for events, the Dahua NVR4108‑8P delivers dependable visual clarity.

High Efficiency and Smart Compression

This recorder supports Smart H.265+, Dahua’s advanced video compression algorithm that significantly reduces bandwidth and storage needs—by up to 80% compared to traditional H.264—without compromising image quality.

This feature is crucial for setups that need extended recording retention or operate on limited storage resources. It’s especially effective when paired with Dahua’s Smart IP cameras, which are optimized for Smart Codec support.

Built-in PoE for Streamlined Installations

The Dahua NVR4108‑8P 8-port PoE switch supports both IEEE 802.3af and 802.3at standards. With up to 25.5W per port and a total power budget of around 72W, it can support a full range of standard IP cameras including dome, bullet, turret, and PTZ models.

For system integrators, this significantly reduces deployment time. Each PoE port delivers power and data via a single Ethernet cable, keeping wiring clean and manageable.

Rich AI Video Analytics

This Dahua NVR4108‑8P supports a range of AI-powered functions (varies by model version, such as 4KS3 or EI editions):

• Face Detection & Recognition: Identify individuals, detect facial attributes (glasses, masks, beards), and create real-time alerts.

• Perimeter Protection: Classifies and detects events like tripwire crossing and intrusion, filtering out irrelevant motion (like leaves or animals).

• Smart Motion Detection+ (SMD+): Accurately distinguishes between humans and vehicles in motion-triggered recordings.

• People Counting and Heat Mapping: Useful in retail and public spaces for analyzing foot traffic patterns and occupancy trends.

These analytics enhance security and situational awareness while simplifying the review process for critical incidents.

Multi-channel HD Playback

The Dahua NVR4108‑8P offers simultaneous playback across all 8 channels at up to 1080p, or fewer channels at higher resolution (e.g., 2x 4K streams). You can perform intelligent playback searches based on motion, alarms, or AI events, making it easier to find specific events in long video timelines.

It supports:

• Time-based search

• Event-based search (motion, face, intrusion, etc.)

• Tagging and bookmarking for easy retrieval

• Snapshot capture during playback

4K HDMI and VGA Output

For local viewing, the unit offers:

• 1 × HDMI output (up to 3840×2160 @ 30Hz, 4K UHD)

• 1 × VGA output (up to 1920×1080)

Dual monitor output support allows users to simultaneously view live video and playback, or split views across two screens for broader situational control.

Storage & Backup Options

The NVR supports one internal SATA hard drive (3.5″) with capacities of up to 6TB or higher depending on the specific version. For extended retention or video archiving, external USB drives or remote NAS devices can be used for backups.

Automatic overwrite, video export scheduling, and event-based backup ensure long-term system efficiency and minimal manual intervention.

Compatibility with ONVIF and Third-party Cameras

While optimized for Dahua cameras, the NVR4108‑8P supports ONVIF Profile S, G, and T, allowing integration with a wide variety of third-party IP cameras. This makes it a flexible option for upgrades or hybrid installations where older IP cameras are still in use.

Protocols like RTSP, HTTP/HTTPS, TCP/IP, DHCP, DDNS, FTP, and NTP ensure smooth communication and broad device support across networks.

Remote Access with Mobile and Web Apps

Using Dahua’s DMSS app or web-based client, users can view live video, playback recordings, receive push alerts, and even export footage from anywhere. Features include:

• Remote playback of recorded footage

• Two-way audio via compatible cameras

• AI search functions

• Real-time push notifications for motion, face, or intrusion alerts

The Dahua NVR4108‑8P also supports multi-user access, role-based permissions, and audit logging for enterprise applications.

Build, Power, and Environmental Performance

Dahua NVR4108‑8P Designed to run 24/7, the Dahua NVR4108‑8P is built using high-quality components with heat management, surge protection, and power efficiency in mind.

Power Supply:

• Input: 48–53V DC (with external adapter)

• Power consumption (without PoE): <10W

• PoE Budget: up to 72W across 8 ports

Environmental Range:

• Operating Temperature: −10°C to +55°C

• Humidity: 10%–93% RH (non-condensing)

Its fanless design ensures quiet operation, which is ideal for office, retail, or home environments where noise is a concern.

Easy Installation and Setup

Compact in size, the Dahua NVR4108‑8P fits comfortably in any security cabinet, desktop, or small server rack (1U form factor). With plug-and-play PoE, automatic camera discovery, and user-friendly setup wizards, initial installation takes minutes.

System firmware is upgradeable via USB, local web GUI, or Dahua SmartPSS software. Alerts for device failure, hard drive errors, or PoE overload are displayed locally and can be pushed to remote users.

Typical Applications

• Retail Shops: Monitor entrances, cash registers, and customer behavior using people counting and face detection.

• Office Buildings: Maintain access logs, employee entry control, and perimeter monitoring with SMD+ alerts.

• Warehouses: Oversee operations and loading bays, and prevent unauthorized access.

• Residential Complexes: Monitor public spaces, entrances, and garages while reducing false alarms with AI filtering.
