The Uniview IPC2125LB-SF28(40)-A is a 5MP fixed IR mini bullet network camera with Smart IR night vision up to 30 m, single-cable PoE installation, and an IP67 outdoor-rated body for −30 °C to 60 °C operation. It ships with two fixed lens options: 2.8 mm (SF28, 97.0° wide view) or 4.0 mm (SF40, 79.0° longer-reach view). It supports Ultra 265 compression to reduce NVR storage and bandwidth, and is NDAA compliant.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Shops & storefronts5MP detail sees faces clearly at the register. SF28's 97.0° view covers the whole shop floor from a corner.
Home gates & drivewaysSmart IR sees up to 30 m at night in black & white. SF40's narrower 79.0° view watches the full length of a gate or driveway.
Warehouse & site perimetersIP67 body and −30 °C to 60 °C rating survive rain, dust and heat. PoE single-cable install simplifies mounting on poles and walls.
Government & critical-infrastructure projectsThe camera is NDAA compliant, relevant for procurement that requires equipment from non-restricted sources.
Small offices & multi-camera sitesUltra 265 compression and dual video streams keep bandwidth and NVR storage use low across many cameras, even at 5MP resolution.
Network-security-conscious deploymentsHTTPS encryption, RTSP/HTTP/ONVIF authentication, ARP protection and watermarking harden the camera against common network attacks.
Not the right pick if you need…
- Two-way talk or any built-in audio — no microphone or speaker at all
- Wi-Fi — this is a wired RJ45 camera
- Zoom — the lens is fixed (2.8 or 4.0 mm, chosen at purchase)
- MicroSD card recording — it records to an NVR, no local storage slot
- Color night vision — this camera has Smart IR (black & white) only, no warm-light illuminator
- Alarm in/out wiring for sirens or sensors

How wide a view at each distance
Scene width covered at typical mounting distances — the number you need to work out how many cameras a wall, yard or aisle takes.
| Distance | SF28 · 97.0° | SF40 · 79.0° |
|---|---|---|
| 5 m16 ft | 11.3 m37.1 ft | 8.2 m27.0 ft |

Calculated from the horizontal field of view in the specifications below: width = 2 × distance × tan(FOV ÷ 2). Lens distortion and mounting angle are not included.
Who uses it, where it goes and how to install it
Written for the IPC2125LB-SF28(40)-A from its own specifications: 5 MP 1/3.0" sensor, 2.8 mm or 4.0 mm fixed lens, 30 m Smart IR, PoE (802.3af), IP67.
Who it is for
- Installers on budget multi-camera jobs — Max. 5.0 W on any 802.3af PoE port, ONVIF Profile S/T and Ultra 265 to keep NVR disk use down. It records to an NVR only, so it suits jobs where an NVR is installed anyway.
- Shops and small offices — The 2.8 mm version (97.0°) covers about 11.3 m of width from 5 m away, so one camera in a corner sees most of a small shop floor or office.
- Homes: gates, driveways and side paths — The 4.0 mm version (79.0°) identifies a face up to 9.0 m, and the invisible 850 nm IR lights the scene up to 30 m without showing a lamp at night.
- Warehouses, yards and NDAA projects — IP67 body, −30 °C to 60 °C working range and 4 kV surge protection for outdoor walls and poles; NDAA compliant for tenders that require it.
Where and how to install
- Height and angle — Mount at about 2.5–3.5 m and keep the downward tilt shallow. Lower is easier to tamper with; much higher shows the top of heads instead of faces.
- Faces need a choke point — Aim at a door, gate or counter where people walk toward the camera, within the identify distance: 6.3 m with the 2.8 mm lens, 9.0 m with the 4.0 mm lens.
- Plan night coverage on 30 m — The DORI detect distance (63 m / 90 m) is a daytime figure; in darkness the scene is only lit to about 30 m. Keep eaves, gutters and nearby walls out of the picture, or the IR reflects back and the image turns white or hazy.
- Avoid backlight: this model has DWDR only — WDR is digital (DWDR), not true WDR, so a bright doorway, window or sky behind people turns them into silhouettes. Aim from the bright side toward the inside, and use HLC or BLC where you cannot avoid it.
- Weather, cable and surge — The body is IP67, but the RJ45 and 12 V tail are not: put them in the TR-JB05-A-IN junction box with a TR-A01-IN cable gland. Surge protection is 4 kV; on poles or long outdoor runs add a surge protector and earthing.
- Brackets — Pole without junction box: TR-UP06-B-IN. Pole with junction box: TR-UP06-C-IN-V2. Outside building corners: TR-UC08-C-V2. The 3-axis mount (pan 360°, tilt 0–90°, rotate 360°) lets you level the image on sloped walls.
2.8 mm or 4.0 mm: what you actually see
Same 5 MP sensor, different lens. The 4.0 mm identifies faces about 1.4× farther away (9.0 m vs 6.3 m) but covers only about 73% of the width. At 10 m it puts about 157 pixels on every meter of the scene versus about 115 for the 2.8 mm.
| SF28 · 2.8 mm | SF40 · 4.0 mm | |
|---|---|---|
| Horizontal view angle | 97.0° | 79.0° |
| Width covered at 5 m | 11.3 m | 8.2 m |
| Width covered at 10 m | 22.6 m | 16.5 m |
| Pixels per meter at 10 m | ≈115 px/m | ≈157 px/m |
| Identify a stranger's face up to | 6.3 m | 9.0 m |
| Recognize someone you know up to | 12.6 m | 18.0 m |
| Detect that something is there up to (daytime) | 63.0 m | 90.0 m |
| IR night illumination | 30 m | 30 m |
- Pick 2.8 mm for shop floors, rooms and entrances seen from close: from 5 m away it covers 11.3 m of width, and faces are identifiable up to 6.3 m.
- Pick 4.0 mm for a gate, driveway or corridor where people are 6–9 m away: a face is still identifiable at 9.0 m.
- At night both versions are limited by the 30 m IR: do not count on seeing anything useful beyond about 30 m in darkness.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = 2592 ÷ width at 10 m; face and detect distances are the manufacturer's DORI figures.

5MP PoE Bullet Camera FAQ — IPC2125LB-SF28(40)-A
What resolution and frame rate does the IPC2125LB-SF28(40)-A deliver?
The main stream tops out at 5 MP (2592×1944) at 20 fps; you can also run 4 MP or 3 MP at 20 fps, or drop to 1080p for 30 fps. Compression covers Ultra 265, H.265, H.264 and MJPEG with bit rate from 128 Kbps to 6144 Kbps.
How far can it see in total darkness?
Smart IR at 850 nm illuminates up to 30 m (98.4 ft) and works down to 0 lux — full darkness. The IR is invisible, so the camera does not draw attention at night, and LED power adapts automatically so subjects close to the lens keep detail.
Can I add it to a third-party NVR I already own?
Yes. ONVIF Profile S and Profile T support plus API and SDK make it usable with most third-party NVRs and VMS platforms, and the protocol stack includes RTSP, RTMP, HTTPS, SSL/TLS, SMTP and SNMP. Dual streams let the recorder and mobile clients pull different qualities.
2.8 mm or 4.0 mm — which version should I buy?
The 2.8 mm (SF28) covers 97° horizontally, detecting people to 63 m and identifying at 6.3 m — best for entrances and small courtyards. The 4.0 mm (SF40) narrows to 79° but detects to 90 m and identifies at 9 m — best along walls, lanes and parking rows.
Is it built for outdoor use and restricted tenders?
Yes on both counts. The housing is IP67 rated against dust and rain, powered over PoE with a single cable, and the model is NDAA compliant. Hardening includes HTTPS encryption, strong passwords, RTSP authentication, IP filtering and exportable operation logs — with motion and tampering alarms built in.
The IPC2125LB-SF28(40)-A has no microSD slot. How much NVR storage do I need?
At the maximum bit rate of 6144 Kbps with continuous recording, one camera writes about 66.4 GB per day, so 30 days need about 2.0 TB per camera (8 cameras: about 15.9 TB). At 2048 Kbps it is about 22.1 GB per day, or about 0.66 TB for 30 days. Because it has no local storage, nothing is recorded while the NVR or the cable is down, so put the NVR and PoE switch on a UPS.
What PoE switch and cable do I need for the IPC2125LB-SF28(40)-A?
Any IEEE 802.3af (or 802.3at) PoE port works: the camera draws at most 5.0 W, so 8 cameras need about 40 W of PoE budget. Its network port is 10/100 Mbps, so a Fast Ethernet PoE switch is enough for the camera ports; use a gigabit uplink to the NVR for larger systems (16 cameras at 6144 Kbps add up to about 98 Mbps). Use Cat5e or Cat6 copper up to 100 m per run, or a 12 V DC adapter with a Ø5.5 mm plug where there is no PoE.
Why does the IPC2125LB-SF28(40)-A send so many motion alarms at night, and how do I reduce them?
Its built-in events are plain motion detection and tampering only, with no human or vehicle filter, so insects flying through the IR beam, spider webs, rain, moving branches and car headlights all count as motion. Draw the motion area only over the path people use, lower the sensitivity, keep eaves and plants out of the frame, and clear webs during maintenance. If you need alerts only for people, consider the IPC2125LE-ADF28(40)KM-H, whose cross-line and intrusion events are based on human body detection.
What is the difference between the IPC2125LB-SF28(40)-A and the IPC2125LE-ADF28(40)KM-H?
Both are 5 MP fixed-lens PoE bullets with 2.8 mm or 4.0 mm lenses. The IPC2125LB-SF28(40)-A is the basic model: 1/3.0" sensor, F2.1, 30 m IR, digital WDR, no microphone, no microSD and motion/tamper alarms only, at max. 5.0 W. The IPC2125LE-ADF28(40)KM-H adds a 1/2.7" sensor with F1.6, 50 m IR, 120 dB true WDR, a built-in mic, microSD up to 512 GB and human-based cross-line/intrusion alerts, at max. 5.6 W. Choose the LE for backlit entrances, audio or recording without an NVR; the LB where an NVR records everything and the scene is evenly lit.
How do I view the IPC2125LB-SF28(40)-A on a PC or phone?
On a PC, open the camera's IP address in a browser: plug-in-free live view works in Chrome 57+, Firefox 58+ and Edge 16+, and the page lists the EZStation client for multi-camera viewing. The web interface is in English only. For phone viewing the page lists an app; in most systems you add the NVR rather than each camera to the app, and we can help you set it up.
