CHOOSE YOUR SIZE — TWO MODELS ON THIS PAGE

Rule of thumb: count your PoE cameras, then leave room to grow — a shop with 3 cameras plugs straight into the 04B-P4; pick the 08B-P8 if you may add cameras later. Highlighted rows in the spec table below show every difference between the two.

Is this the right recorder for you?

Plain-language guide for buyers and installers — based only on what this recorder actually does.

Small shops with PoE camerasBuilt-in 4/8-port PoE — plug cameras straight into the recorder, no separate PoE switch or extra cabling to buy.

Growing businessesBuy channels you don't use yet: the 08B-P8 lets you add PoE cameras later without replacing the recorder.

Remote viewing on phoneP2P protocol built in — the owner checks the shop from a phone app without a fixed IP or network skills.

Local-language interface38 GUI languages including Spanish (Latin America), Portuguese (Brazil) and French — your customer operates it in their own language.

Longer video retentionUltra 265 roughly halves file size versus H.264 — the same 24 TB disk keeps weeks more footage.

Rack-mounted installsAn optional 1U rack mount (RM-1U-260) is available for this chassis — tidy server-room installs alongside other 1U gear.

Not the right pick if you need…

Gigabit network uplink — the built-in network port is 10/100M (matched to this series' 80 Mbps bandwidth)
A second hard disk or RAID — this series has a single SATA bay
Serial PTZ control from the NVR itself — RS485 and RS232 are both listed N/A on this series
Physical alarm input/output terminals — Alarm In and Alarm Out are both N/A on the rear panel
Extra PoE budget for high-draw cameras — each port is capped at 30 W (standard PoE/PoE+, not PoE++ 60W+ devices)

Worried about counterfeits? Order under your own company name.

For corporate buyers: we support submitting the purchase order to Uniview under your company's real name — your company appears on the official order, so the origin of the goods can be verified directly with the manufacturer. Just provide your company name and pay by corporate bank transfer. Models carrying the anti-counterfeit label can also be self-verified on Uniview's official Anti-Counterfeiting Query page — enter the unit's SN plus the scratch-off code.

Cameras plug in. The recorder watches for you.

Two real capabilities that define this series: built-in PoE and onboard Smart by IPC detection.

PLUG & PLAY POE

No separate PoE switch to buy

Each RJ45 port is independent PoE — up to 30 W per port, 50 W total on the 04B-P4 or 75 W total on the 08B-P8 (IEEE 802.3at/af) — plug cameras straight into the recorder.

SMART BY IPC

Real alerts, not hours of nothing

Built-in Face Detection, Intrusion Detection (SIP) and Ultra Motion Detection (UMD) run on up to 8 channels (4 on the 04B-P4), feeding Face Snapshot Search, Motor/Non-Motor Vehicle Search, Human Body Search, General Search, People Counting Report and Heat Map — search by event, not by scrubbing the timeline.
