AI general description and features

The NVR2000-4KS3 Lite Series, which includes the DHI-NVR2104-4KS3, is designed as a 4-channel 4K network video recorder with the ability to operate as edge, central or backup storage, with an intuitive shortcut menu for remote management and control, according to the manufacturer's documentation. Applied Smart Motion Detection technology (SMD PLus) with intelligent algorithm allows to categorize objects triggering motion detection and filter alarms triggered by irrelevant objects, increasing the efficiency and accuracy of alarms.

Perimeter protection and channel operation

The perimeter protection implemented by the cameras automatically filters out false alarms caused by animals, rustling leaves, strong lights and similar disturbances, enabling the system to identify targets secondarily and improving alarm accuracy. All channels can support perimeter and SMD protection functions on the camera side (up to 4 targets/s for perimeter protection and up to 8 targets/s for SMD), while on the DVR side, 4 channels support SMD PLus with secondary filtering of human objects and motor vehicles, reducing false alarms caused by leaves, rain or changes in lighting.
