16 Independent PoE Ports
Connect up to sixteen IP cameras straight to the recorder — each carries power and video over one Cat6 run, so there are no separate power supplies or extra switch to wire for your first 16 channels.
150W PoE Budget
Up to 30W per port (IEEE 802.3at/af) and 150W across all ports together, comfortably powering domes, bullets and most PTZ-lite cameras without an external injector.
Scale to 32 Channels
Add the remaining channels from a PoE switch or self-powered cameras to reach the full 32-channel capacity — ideal for growing sites that start small.
ONVIF & Ultra 265
Works with mainstream ONVIF cameras (Profile S/G/T) and Ultra 265 compression that cuts storage and bandwidth by up to 75% versus H.264.
RAID 1 & RAID 5 Protection
Four SATA bays support RAID 1 mirroring and RAID 5 parity, plus disk groups and redundant storage, so a single drive failure won't cost you footage.
Up to 64TB Across 4 Bays
Each of the four bays takes a SATA drive up to 16TB, for around 64TB of raw capacity — weeks of continuous recording across all 32 channels.
ANR Anti-Dropout
If the network link drops, ANR keeps recording to the camera's onboard SD card and backfills the NVR once the connection returns — no gaps in the timeline.
4K HDMI + VGA Output
Drive a 4K display over HDMI and a second monitor over VGA at the same time for a true dual-screen control-room view.
Recording time depends on how many cameras you run, their resolution and frame rate, and whether you record continuously or on motion. The estimates below assume 32 cameras at 4MP, H.265, ~4 Mbps continuous — a typical real-world load for a fully populated system. Smart/motion-only recording, lower resolution or fewer cameras will extend retention significantly. Maximum capacity is four SATA drives at 16TB each (64TB).
Figures are estimates for guidance only and will vary with scene activity, bitrate and camera settings.
How many PoE cameras can it power directly?Up to 16 cameras connect straight to the NVR's built-in PoE ports, each carrying power and video over a single Cat6 cable. The PoE budget is 30W per port and 150W in total, which covers most domes, bullets and compact PTZ cameras.
Can it really run 32 channels with only 16 PoE ports?Yes. The first 16 cameras can use the built-in PoE ports, and the remaining channels are added over your network from a PoE switch or self-powered cameras — up to 32 IP channels in total.
What's the maximum storage and does it support RAID?Four SATA bays each take up to 16TB, for around 64TB total. It supports RAID 1 mirroring and RAID 5 parity, plus disk groups and redundant storage, so footage survives a single drive failure.
What resolution can it record?Up to 16MP (4K Ultra HD) per channel in Ultra 265, H.265 or H.264, so it's ready for high-resolution Uniview UNV cameras while keeping storage use low.
What smart features does it have?This is the standard (non-IQ) model. It passes through camera-side analytics — Face Detection, Vehicle Detection, Smart Intrusion Prevention (SIP), Ultra Motion Detection, People Counting and more — and lets you search recordings by human body, vehicle and event. AcuSearch and SeekFree are reserved for the IQ models.
Is it NDAA compliant?Yes. Like all Uniview UNV recorders we stock, the NVR504-32B-P16 is NDAA compliant, making it suitable for government, education and enterprise projects with procurement requirements.
Does it work with third-party cameras?Yes, via ONVIF Profile S, G and T, so you can mix in compatible cameras from other brands alongside your Uniview UNV units.
Can I view it remotely?Yes. P2P cloud access through the EZView / EZCloud app lets you watch live and recorded footage from your phone or computer anywhere, with no fixed IP needed.
What's in the box and what warranty applies?The recorder ships with its power adapter and accessories (hard drives sold separately) and is backed by a 3-year Australian warranty with local CCTV Guru support.
