DAHUA NVR2104-P-4KS3 is a compact 4-channel network video recorder with four built-in PoE ports, designed to simplify IP camera installations for small offices, retail outlets and residential sites. The unit supports Smart H.265+, H.265, Smart H.264+, H.264 and MJPEG decoding formats, offers a maximum decoding capability of 6 × 1080p@30 fps and handles up to 80 Mbps incoming, 80 Mbps recording and 60 Mbps outgoing bandwidth. The recorder accepts IP camera inputs up to 12 MP and integrates AI features including 4-channel SMD Plus on the recorder and perimeter protection and SMD Plus when paired with compatible AI cameras.
Advantages
The DAHUA NVR2104-P-4KS3 combines PoE power and data on four ports for direct camera connection, reducing cabling and simplifying deployment. Its support for modern codecs such as Smart H.265+ improves storage efficiency and network load compared with legacy formats. Small physical dimensions and a single 3.5" HDD bay make the device suitable for installations with limited space while providing local recording and playback via HDMI or VGA outputs. Built-in AI capabilities enable more accurate motion filtering and perimeter event detection when used with supported cameras.
Suitable for
- Small office surveillance with up to four IP cameras
- Retail storefronts and point-of-sale monitoring
- Residential and apartment building security
- Remote sites where compact PoE-enabled NVR is preferred

How to use
Install a compatible 3.5" HDD in the internal bay before powering the unit to enable local recording. Connect IP cameras directly to the four PoE ports to provide both power and network connectivity, or use the additional RJ45 port(s) for uplink to the local network. Configure recording schedules, motion detection and AI event rules through the NVR’s web interface or client software, and connect a monitor via HDMI or VGA for local live view and playback. Use the USB ports for mouse control or to export recorded video to external storage.
Usage recommendations
For reliable continuous recording, choose an HDD designed for surveillance use and configure storage management (overwrite or scheduled backup). Place the NVR in a ventilated, dust-free environment within the specified temperature range. When enabling AI features such as SMD Plus and perimeter protection, ensure connected cameras support required AI functions and that firmware is up to date to maintain detection accuracy.
