System description and features

The DHI-NVR2104-P-4KS3 NVR is part of the NVR2000-4KS3 Lite Series NVR and is designed for applications requiring detailed 4K video and remote management and control from an intuitive menu. It can operate as an edge, central or backup device, offering support for up to 12 MP IP cameras and a maximum throughput of 80 Mbps for incoming streams and recording and 60 Mbps for outgoing streams.

The device features an industrial-grade processor and Embedded Linux operating system, and is operated via a Web interface and local GUI. The DVR supports dual-stream decoding in Smart H.265+, H.265, Smart H.264+, H.264 and MJPEG formats, with a maximum decoding performance of 6 × 1080p@30 fps with AI functions disabled and correspondingly reduced when enabled, according to the manufacturer's specifications.

Smart and network functions

SMD's PLus (AI by Recorder) function uses Dahua's Smart Motion Detection algorithms to classify objects that trigger motion detection and filter out alarms generated by irrelevant targets, enabling secondary object recognition and increasing alarm performance. AI by Camera provides perimeter and SMD protection on all channels, with up to 4 targets/sec for perimeter protection and 8 targets/sec for SMD PLus on camera channels, with secondary filtering of false alarms caused by, for example, animals, leaf noise, changes in lighting or precipitation.

The DVR supports network protocols HTTP, HTTPS, TCP/IP, IPv4/IPv6, UDP, NTP, DHCP, DNS, SMTP, IP Filter, DDNS, IP Search (for IP cameras, DVRs, NVS, etc.), P2P and Auto Registration, enabling interoperability with third-party devices thanks to ONVIF 23.12 (Profiles T, S, G), as well as CGI and SDK. Mobile access is realized via iOS and Android devices, and viewing and configuration via Chrome, IE, Safari, Edge and Firefox browsers.

Recording, playback and alarms

The device supports general, motion detection, smart and alarm recording, with playback of up to 4 channels simultaneously. Instant, general, event, post-tag and smart playback modes are available, and backups can be made to USB devices and over the network. The alarm system includes general alarms (motion detection, external camera alarm, PIR alarm), anomaly alarms (no disk, disk error, low capacity, low space limit, network disconnection, IP conflict, MAC conflict, video loss, camera tampering, offline camera) and smart alarms (perimeter protection, SMD PLus) with related responses such as recording, still images, beep, log, PTZ preset call, email and route.
