Dahua NVR2104HC-W
The Dahua NVR2104HC-W network recorder is used for storing and managing recordings from IP cameras in security systems. The device is powered by an industrial processor with an Embedded Linux operating system, which processes video footage from 4 connected cameras. Users can watch live video or playback recordings on a monitor connected via the HDMI or VGA interface. This device supports automatic pairing with wireless cameras and can handle a total incoming data stream of up to 80Mb/s. Recordings are stored on a hard drive, with the system recording in resolutions up to 16MP. The system triggers an alarm in the event of a perimeter breach, video signal loss, camera view obstruction, or unauthorised tampering with the device. The recorder sends instant notifications to mobile phones running iOS and Android operating systems. Users can activate monitoring with a single click in the app, simplifying the daily operation of the entire system. Alarm outputs are also available in the form of a buzzer or email messages.

Wireless connection
The device includes a built-in Wi-Fi module supporting 802.11b/g/n/a/ac/ax standards, which operates on the 2.4GHz and 5GHz bands. Two external antennas help maintain a stable connection with the cameras, even over longer distances. The recorder can connect directly to IP cameras wirelessly without needing an additional access point. This reduces the cost of purchasing extra network hardware.
Video decoding
The recorder supports Smart H.265+, H.265, Smart H.264+, H.264, and MJPEG compression formats, which reduce data stream and storage requirements. The decoding capacity is up to 10 channels at 1080p and 30fps or 4 channels at 5MP and 30fps. Users can connect IP cameras with resolutions up to 16MP to the recorder for detailed monitoring of the secured area. The recording data stream is 80Mb/s.
Intelligent detection
The device uses advanced SMD Plus technology on 4 channels, which focuses on detecting people and vehicles. This system filters out false alarms caused by falling leaves, rain, or changes in lighting conditions. The recorder analyses video footage in real time and reacts only to genuine threats. When connected with compatible cameras, it also supports perimeter protection and classic motion detection.
Storage capacity
For data storage, there is a single SATA hard drive bay with a capacity of up to 20TB. The recorder offers functions for continuous recording, motion-activated recording, or recording based on a set schedule. Users can back up data to a USB drive or via the network interface. The system supports automatic overwriting of old recordings when the drive capacity is full.
Network features
Connectivity is provided by one 10/100Mb/s RJ-45 ethernet port. The recorder supports network protocols such as HTTP, HTTPS, TCP/IP, IPv4, IPv6, DHCP, and P2P for easy remote connection without needing a public IP address. Users can access the system via Chrome, Edge, Safari, or Firefox web browsers. Compatibility with the ONVIF protocol supports interoperability with cameras from other manufacturers.
