Series description and features
The NVR2000-4KS3 Lite Series are compact network video recorders designed for high-resolution applications, including 4K video support, with an intuitive interface for remote management and control, according to the manufacturer's documentation. The DHI-NVR2104HS-P-4KS3 can operate as an edge, central or backup device, offering Smart Motion Detection (SMD) features to distinguish between people and vehicles and reduce false alarms.
Smart and alarm functions
The Smart Motion Detection PLus (SMD PLus) technology used in the DHI-NVR2104HS-P-4KS3 enables secondary filtering of targets (people and motor vehicles), reducing false alarms caused by, for example, leaves, rain or changes in lighting, according to the manufacturer's documentation. The DVR also supports perimeter protection functions implemented by the camera (perimeter protection), as well as general alarms, anomalies (no disk, disk error, low space, network error, IP/MAC conflict, video loss, video tampering, offline camera), and alarm links such as recording, photo, buzzer, log, preset, email and route.
Video, network and interface support
The DHI-NVR2104HS-P-4KS3 supports multiple video (Smart H.265+, H.265, Smart H.264+, H.264, MJPEG) and audio (G.711a, G.711u, PCM, G726) compression formats, offering HDMI and VGA outputs with various resolutions, including up to 3840 × 2160 on HDMI. The device has 4 access channels, a 10/100 Mbps RJ-45 network port, two USB 2.0 ports (one on the front, one on the back) and multi-screen (1/4) viewing modes, as well as support for third-party cameras via ONVIF and HTTP, HTTPS, TCP/IP, IPv4/IPv6, UDP, NTP, DHCP, DNS, SMTP, IP Filter, DDNS, IP Search, P2P and Auto Registration protocols, according to the manufacturer's documentation.
