Product Description
The Dahua DHI‑NVR2108‑4KS3 is a reliable and compact 8‑channel NVR from Dahua’s 4KS3 Lite Series, designed to record and manage IP cameras with high‑definition video quality. It supports multiple video compression formats, including Smart H.265+, H.265, Smart H.264+, H.264, and MJPEG, optimizing storage efficiency and reducing bandwidth usage.
This recorder supports IP cameras with resolutions up to 12 MP, making it compatible with most modern Dahua and third‑party cameras. The built‑in smart motion detection (SMD Plus) improves event filtering by distinguishing between human/vehicle motion and irrelevant triggers (like trees or pets) when used with compatible cameras.
For local monitoring, the NVR offers simultaneous HDMI (up to 4K) and VGA outputs, with multi‑screen display modes for flexible live view layouts. Playback supports multiple channels simultaneously, and remote viewing is available through Dahua’s mobile apps (DMSS), web browsers, or SmartPSS software. ONVIF support enables seamless integration with a range of third‑party cameras.
