The Dahua NVR4216-16P-EI is a powerful WizSense network video recorder designed for advanced surveillance applications. It supports Smart H.265+/H.264+ compression formats, reducing bandwidth and storage requirements while maintaining high‑quality video. With a maximum bandwidth of 256 Mbps and decoding capability up to 16 × 1080p@30 fps or 4 × 8 MP@30 fps, it ensures smooth recording and playback.
AI features include 1‑channel face detection and recognition, 2‑channel perimeter protection, 4‑channel SMD by recorder, and extended AI by camera functions such as people counting, stereo analysis, and heat map visualization. The recorder supports up to 10 face databases with 20,000 images, enabling efficient facial recognition and metadata management.
It offers simultaneous HDMI/VGA output (up to 4K), multi‑screen display options, and compatibility with major third‑party cameras (Panasonic, Sony, Hanwha, Axis, Pelco, Arecont, Canon, ONVIF). With dual SATA ports supporting up to 20 TB, 16 PoE ports, and robust alarm/event management, this NVR is ideal for large‑scale surveillance deployments in public safety, transportation, education, and enterprise environments.
