The Dahua NVR2108HS-8P-4KS3 is a cutting-edge 8-channel Network Video Recorder (NVR) designed to be the central hub of your surveillance system. Engineered with an industrial-grade processor and embedded Linux operating system, it offers stable and reliable performance for continuous monitoring.

Unmatched Video Quality: Experience unparalleled clarity with support for IP cameras up to 12 Megapixels (MP) resolution. The NVR can decode up to 6 channels of 1080p video at 30 frames per second (fps) simultaneously (AI disabled), ensuring you capture every detail. With HDMI output supporting resolutions up to 3840 × 2160 (4K), you can view your footage on high-definition monitors.

Simplified Installation with PoE: Featuring 8 built-in Power-over-Ethernet (PoE) ports, this NVR makes camera installation incredibly straightforward. A single Ethernet cable provides both power and video transmission to your compatible IP cameras, reducing wiring complexity and installation costs.

Intelligent AI Surveillance: Leverage the power of artificial intelligence to enhance your security. The NVR2108HS-8P-4KS3 comes with AI by Recorder (4-channel SMD Plus), providing intelligent motion detection that accurately identifies human and vehicle targets while significantly reducing false alarms caused by environmental factors like rain, leaves, or lighting changes. When paired with AI-enabled cameras, it further supports Perimeter Protection and SMD Plus across all channels, offering more precise detection capabilities. Features like "one-click arming and disarming" add convenience to your security management.

Efficient Storage & Bandwidth Management: Benefit from Dahua's advanced compression technologies, including Smart H.265+, H.265, Smart H.264+, and H.264. These formats drastically reduce file sizes, allowing you to store more footage on your single SATA hard drive (up to 20TB capacity, HDD not included) without sacrificing video quality. The NVR supports a maximum incoming/recording bandwidth of 144 Mbps (AI disabled), ensuring smooth recording from all connected cameras.

Seamless Access & Integration: Access your surveillance system anytime, anywhere with mobile phone access via iOS and Android apps. The NVR supports a wide range of network protocols and is ONVIF compliant, ensuring compatibility with a broad array of third-party IP cameras. Manage your system easily through a web browser (Chrome, IE, Safari, Edge, Firefox) or the local GUI.

Reliable Recording & Playback: Set up various recording modes including general, motion detection, intelligent, and alarm-triggered recording. Easily search and playback footage with options for instant, general, event, tag, and smart playback. Back up important video clips conveniently to a USB device or over the network.
