Hikvision DS-7732NI-Q4/16P 32-Channel 16-PoE NVR

The DS-7732NI-Q4/16P is a 32-channel Hikvision recorder for sites that need plenty of cameras and storage in one box: estates, schools, warehouses, and office buildings. Sixteen cameras plug directly into its PoE ports, and more connect through a switch on its gigabit network ports.

It records cameras up to 8 MP, with 160 Mbps of incoming bandwidth, and decodes one 8 MP or six 1080p channels at once for live view. HDMI (up to 4K) and VGA outputs run simultaneously.

Four SATA bays take drives of up to 8 TB each. Sixteen alarm inputs and four alarm outputs connect door contacts, beams, and sirens, and RS-485 and RS-232 ports link to PTZ keyboards and other equipment. Smart events from compatible cameras, such as line crossing and intrusion, can trigger recording and alerts.

It runs from 100–240 V AC. We size the hard drives to how many days of recording you need to keep, and connect the recorder to a UPS or inverter so it keeps recording through power cuts.
