The Hikvision DS-7732NXI-I4/16P/S(E) is a 32-channel network video recorder for IP cameras up to 32MP (8K), with a built-in 16-port PoE switch so each camera needs only one network cable for power and video.
AcuSense filters motion alerts down to people and vehicles, so a swaying tree or passing cat no longer fills your phone with notifications. It takes 4 SATA hard drives of up to 16TB each. No hard drive is included: choose one from our surveillance hard drives.
