Technical Specifications

Hikvision DS-7332HUHI-K4 32-Channel 8 MP Turbo HD DVR

The Hikvision DS-7332HUHI-K4 is a high-capacity 1.5U digital video recorder designed for large surveillance systems requiring centralized recording, flexible camera compatibility, and dependable storage. Its 32 analog channels can be combined with supported IP cameras for configurations of up to 48 network-camera channels.

Adaptive support for HDTVI, AHD, HDCVI, CVBS, and IP signals makes it easier to maintain an existing coaxial system while gradually introducing newer cameras. Four SATA interfaces, eSATA support, RAID mode, H.265 Pro+ compression, dual Gigabit Ethernet ports, and dual HDMI outputs provide the storage capacity and connectivity needed for demanding commercial installations.
