NVR Dahua Technology Lite NVR2104HS-4KS3 4 Channels 4K Black

The NVR2000-4KS3 Lite Series network video recorder supports 4K resolution and is designed for use as edge, central, or backup storage. It provides an intuitive shortcut menu for remote management and includes Smart Motion Detection (SMD) by recorder to distinguish vehicles and humans in real time. The model is easy to install and cost-effective, suitable for villas, shops and other small to medium-sized scenes.

Advantages

The recorder offers 4K decoding capability and supports multiple video codecs including Smart H.265+, H.265, Smart H.264+, H.264 and MJPEG. Built-in AI functions reduce false alarms by classifying moving targets and enabling perimeter protection at the camera level. The unit supports one-click arming/disarming and can be used as edge, central or backup storage for flexible deployment.
