Dahua NVR5432-16P-4KS2E 32-Channel 16-PoE 4K Pro NVR

The NVR5432-16P-4KS2E is a 32-channel Dahua Pro recorder for mid-size sites such as office buildings, hotels, schools, and estates. Sixteen cameras plug straight into its PoE ports for power and video (up to 25.5 W per port, 150 W in total), and the other 16 connect through a network switch.

Ports 1–8 support ePoE and EoC. ePoE carries power and data up to 800 m, well beyond the usual 100 m network-cable limit, and EoC runs over existing coaxial cable, which helps when upgrading an old analogue system without re-cabling.

It has 320 Mbps of incoming bandwidth, handles cameras up to 24 MP, and records with Smart H.265+. Four SATA bays take drives of up to 10 TB each, with an eSATA port for more. AI functions such as perimeter protection, face detection, SMD Plus, and ANPR are supported, some requiring AI cameras. Two HDMI and two VGA outputs drive separate monitors.

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.
