## Long description

DAHUA Lite NVR2104-P-S3 is a 4-channel network video recorder in a 1U rack form factor with an embedded Linux operating system. Designed for small and medium surveillance installations, it supports one SATA drive up to 16 TB, a single RJ-45 10/100 Mbps LAN port, two USB 2.0 ports and multiple audio formats including G.711 A/μ, G.726 and PCM.
