Dahua Technology N52B5P4 Pro Series 32-Channel 4K UHD ePoE NVR with 4TB HDD

Record from, and manage, up to 32 cameras with the N52B5P Pro Series 32-Channel 4K UHD ePoE NVR from Dahua Technology at resolutions up to 3840 x 2160. Equipped with two SATA III ports, the NVR can support up to 20TB of internal storage (4TB preinstalled). Eight out of the NVR's 16 PoE ports support ePoE and EoC with the use of an optional EoC converter. ePoE offers a cost-effective solution for transmitting power and data over long distances via Ethernet or coaxial cables. Two-way audio is supported via RCA audio ports.

This NVR supports simultaneous HDMI and VGA outputs, as well as up to 128 users. With the help of H.265+, H.265, H.264+, H.264, and MJPEG compression, file sizes are kept manageable while recording and playback quality are maintained. ONVIF-compliance for version 2.4 enables interoperability with ONVIF-compliant cameras.
