The Uniview UNV NVR501-04B-P4 is a 4-channel, 1-bay network video recorder with 4 built-in PoE ports, so you simply run a single network cable to each camera and it powers up and connects automatically — true plug & play. It records up to 16MP resolution in Ultra 265, H.265 or H.264, holds one SATA drive up to 24TB for weeks of continuous footage, and decodes up to 4 × 4K streams for smooth live view and playback. With NDAA-compliant hardware and a compact 1U body, it's an ideal recorder for homes, shops and small offices running up to four Uniview UNV IP cameras.

Max Recording16MP / 4K
Plug & play PoE with smart detection
4 Built-in PoE Ports
Four independent PoE ports power and connect your cameras over a single cable each — up to 30W per port and 50W total, with IEEE 802.3at/af support. No separate switch or power supplies needed.
Smart Detection by Camera
Run Face Detection, Smart Intrusion Prevention (SIP) and Unattended/Missing Detection (UMD) across all 4 channels when paired with compatible Uniview UNV IP cameras.
VCA Smart Search
Filter recorded footage by Motor Vehicle, Non-Motor Vehicle and Human Body, plus People Counting and Heat Map reporting — find events fast instead of scrubbing for hours.
Up to 16MP Recording
Records the latest high-resolution cameras at up to 16MP in efficient Ultra 265, with smooth decoding of up to four 4K streams for crisp live view and playback.
Built for reliable, always-on recording
Single SATA Bay up to 24TB
One SATA bay supports a hard drive up to 24TB, giving a 4-camera system weeks of continuous recording on a single disk.
ANR Anti-Dropout
If the network drops, ANR keeps recording to the camera's onboard SD card and backfills the NVR once the link returns — no gaps in your timeline.
4K HDMI + VGA Output
Drive a 4K display over HDMI and a second monitor over VGA simultaneously for a true dual-screen view on a compact 1U recorder.
NDAA Compliant
Built to NDAA Section 889 requirements, making it suitable for government, education and enterprise projects with procurement rules.

How much footage can it hold?
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 4 cameras at 4MP, H.265, ~4 Mbps continuous — a typical real-world load. Smart/motion-only recording, lower resolution or fewer cameras will extend retention significantly. Maximum capacity is a single SATA drive up to 24TB.
Approximate Recording Retention (4 × 4MP, H.265)
| 4 TB |
~24 days continuous · ~55 days motion-based |
| 8 TB |
~48 days continuous · ~110 days motion-based |
| 12 TB |
~71 days continuous · ~160 days motion-based |
| 16 TB |
~95 days continuous · ~215 days motion-based |
| 24 TB (max) |
~143 days continuous · ~320 days motion-based |

Frequently Asked Questions
Does this NVR have built-in PoE ports?Yes. The NVR501-04B-P4 has 4 built-in PoE ports, so each camera connects and powers up over a single network cable — no separate PoE switch or power supplies required. It's true plug & play.
How many cameras can it record?Up to 4 IP cameras at once, with 80 Mbps of incoming bandwidth — enough headroom for high-megapixel cameras on a 4-channel system.
What's the maximum storage?The single SATA bay takes a hard drive up to 24TB, giving a 4-camera system weeks of continuous recording. Drives are sold separately.
What resolution can it record?Up to 16MP per channel in Ultra 265, H.265 or H.264, so it's ready for 4K and higher-resolution Uniview UNV cameras.
How much PoE power does it provide?Each port delivers up to 30W, with 50W available across all four ports combined (IEEE 802.3at/af) — enough to run four standard turret, dome or bullet cameras.
Is it NDAA compliant?Yes. The NVR501-04B-P4 is NDAA Section 889 compliant, making it suitable for government, education and enterprise projects with procurement requirements.
Does it work with third-party cameras?Yes, it supports mainstream ONVIF-compliant IP cameras. Smart functions such as Face Detection and SIP run best with compatible Uniview UNV cameras.
