The Dahua NVR2104HC-W is a 4-channel wireless network video recorder built for small and medium-sized surveillance systems that need a straightforward, cable-free setup. With Wi-Fi 6 connectivity and automatic pairing with compatible wireless cameras, it removes the complexity typically involved in installing a network video recorder.
Powered by an industrial-grade processor, the Dahua NVR2104HC-W supports IP cameras with resolution up to 16MP, giving it the flexibility to work with a wide range of camera models, from standard HD units to higher-resolution surveillance cameras.
Wireless performance is a defining strength of this recorder, built around dual high-gain antennas and full Wi-Fi 6 support. This ensures stable transmission with low latency, even when multiple cameras are streaming simultaneously across the same network.
The Dahua NVR2104HC-W offers flexible deployment options, supporting both AP mode for creating a dedicated surveillance network and Station mode for connecting to an existing network. This adaptability makes it suitable for a wide range of installation environments and household or business layouts.
Intelligent detection is built directly into the system through SMD Plus, which filters false alarms caused by leaves, rain, or changing light conditions across all four channels. When paired with AI-enabled cameras, the recorder also supports perimeter protection for more accurate alerts.
With a maximum decoding capability of 10 × 1080p at 30 fps and support for up to 80 Mbps of incoming, recording, and outgoing bandwidth, the Dahua NVR2104HC-W handles multiple video streams smoothly. A single bay supports HDD storage up to 20TB for extended recording history.
Combining Wi-Fi 6 connectivity, automatic camera pairing, and intelligent motion filtering, the Dahua NVR2104HC-W offers a dependable, easy-to-deploy recording solution for homes and small businesses building out a wireless surveillance system.
