Dahua NVR2116HS-4KS3 – 16-Channel IP Network Video Recorder

IP video surveillance in retail stores, offices and small commercial sites depends on a stable central recording point. The Dahua DHI-NVR2116HS-4KS3 16-channel NVR fills that role in a compact form factor, managing IP cameras up to 12 MP with 4K display output. Smart human and vehicle detection cuts false alarms. The network video recorder serves as edge, central or backup storage in distributed security systems.

Smart H.265+ compression reduces archive size and network load, extending retention on a single SATA drive of up to 20 TB. With 144 Mbps of incoming bandwidth, the recorder has headroom for all 16 channels. HDMI 4K and VGA outputs connect directly to a monitor at the security desk. Recorder-side SMD Plus runs on 4 channels, filtering motion triggered by leaves, rain or lighting changes and flagging only people and vehicles. Power draw under 10 W without a drive and an operating range of −10 °C to +55 °C simplify installation in network cabinets or on technical shelves.

ONVIF 23.12 support (Profile S, G and T) allows third-party IP cameras to run alongside Dahua models. Paired with Dahua AI cameras, the system extends perimeter protection and SMD to every channel. A single Gigabit Ethernet port links the NVR to the local network, with cameras connected through the existing switch. Management runs through the web interface, local GUI and iOS or Android apps, with remote access via P2P and DDNS. Alarm events can trigger recording, snapshots, a buzzer or email notifications, and footage can be backed up to USB or over the network.

For retail stores, small offices, warehouses and branch locations, the DHI-NVR2116HS-4KS3 delivers IP surveillance for up to 16 cameras without oversized infrastructure. Security integrators gain fast commissioning, open camera choice through ONVIF, and CGI and SDK access for custom integration. One-click arming and disarming streamlines closing routines, while smart and event-based playback shortens incident review. In multi-site networks, the recorder acts as on-site storage with remote access to footage from head office.
