The Uniview IPC2128LB-ADF28(40)K-G is an 8MP fixed IR mini bullet network camera with an IP67 outdoor rating and a −30 °C to 60 °C working range. It provides up to 30 m of smart infrared night vision, a built-in mic, MicroSD edge storage up to 512 GB, and powers over a single PoE cable or DC 12 V. It is offered with two fixed lenses: 2.8 mm (ADF28K, wider view) or 4.0 mm (ADF40K, longer reach).
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Shops & storefronts8MP detail keeps faces and price tags identifiable, and the built-in mic records what is said at the counter. ADF28K covers the whole shop floor from a corner.
Home gates & drivewaysCross line and intrusion alerts are based on human body detection, so they trigger on people crossing the line — not on pets or branches.
Warehouse & site perimetersIP67 body and −30 to 60 °C rating survive rain, dust and heat. ADF40K reaches 90 m DORI detect range for long fence lines.
Government & regulated projectsNDAA-compliant construction fits procurement rules that restrict certain countries of origin.
Remote sites with weak networkMicroSD edge storage up to 512 GB keeps recording when the network drops, with ANR to fill the gap on the NVR once it's back.
Kiosks & fuel stationsDual power — PoE or DC 12V — gives flexibility at the pole. One PoE cable can carry power and video together for a quick install.
Not the right pick if you need…
- Two-way talk — it has a mic but no speaker
- Wi-Fi — this is a wired RJ45 camera
- Zoom — the lens is fixed (2.8 or 4.0 mm, chosen at purchase)
- Full-color night vision — this model has an IR illuminator only, so night footage is black & white
- 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.

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 IPC2128LB-ADF28(40)K-G from its own specifications: 8 MP (3840 × 2160) 1/2.7" sensor, 2.8 mm or 4.0 mm fixed lens, 30 m Smart IR, built-in mic, microSD up to 512 GB, PoE or 12 V DC.
Who it is for
- Security installers and integrators — Max. 5.0 W on any 802.3af PoE port, ONVIF Profile S/G/T for Uniview or third-party NVRs, and a 13-language web interface with 3 user levels for handover.
- Shops and storefronts — 3840 × 2160 lets you zoom into recorded video to read details at the counter, and the built-in mic records what is said there. The 2.8 mm version (107.0°) covers about 13.5 m of width from 5 m away.
- Homes, gates and driveways — Cross-line and intrusion alerts are based on human body detection, and the 4.0 mm version identifies a face up to 9.0 m. Invisible 850 nm IR lights the scene up to 30 m.
- Remote sites, kiosks and NDAA projects — A microSD card up to 512 GB keeps recording when the link drops and ANR fills the NVR gap afterwards; PoE or 12 V DC power, IP67, −30 °C to 60 °C, NDAA compliant.
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.
- Backlight and headlights — 120 dB WDR handles a bright doorway or glass front behind people, but do not aim straight at the rising or setting sun. Where car headlights come toward the camera, turn on HLC.
- 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 and hallways — Pole without junction box: TR-UP06-B-IN; pole with junction box: TR-UP06-C-IN-V2; outside corners: TR-UC08-C-V2. For a hallway, mount the camera turned 90° and set the image to 90° rotation so the frame is tall and narrow.
2.8 mm or 4.0 mm: what you actually see
Same 8 MP sensor, different lens. The 4.0 mm identifies faces about 1.4× farther away (9.0 m vs 6.3 m) but covers about 76% of the width. At 10 m it puts about 188 pixels on every meter of the scene versus about 142 for the 2.8 mm.
| ADF28K · 2.8 mm | ADF40K · 4.0 mm | |
|---|---|---|
| Horizontal view angle | 107.0° | 91.2° |
| Width covered at 5 m | 13.5 m | 10.2 m |
| Width covered at 10 m | 27.0 m | 20.4 m |
| Pixels per meter at 10 m | ≈142 px/m | ≈188 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 a shop floor, office or yard seen from close: from 5 m away it covers 13.5 m of width.
- Pick 4.0 mm for a gate, driveway or fence line 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 = 3840 ÷ width at 10 m; face and detect distances are the manufacturer's DORI figures as shown on this page.

4K 8MP Bullet Camera FAQ — IPC2128LB-ADF28(40)K-G
Is the IPC2128LB-ADF28(40)K-G a real 4K camera?
Yes — the main stream outputs 8 MP at 3840×2160 (4K) at 15 fps on a 1/2.7-inch CMOS sensor. If you need smoother motion, drop to 5 MP or 4 MP at 25/20 fps or 1080p. Bit rate is adjustable from 128 Kbps up to 16 Mbps.
Can I power it without a PoE switch?
Yes. Besides PoE over the network cable, it accepts a local DC12V supply — handy when replacing older analog cameras that already have 12V wiring in place, or on sites without PoE infrastructure. With PoE, one cable carries power, video and audio together.
What are the night vision and low-light specs?
Smart IR at 850 nm reaches up to 30 m (98.4 ft) and works down to 0 lux. The fast F1.6 lens holds color to 0.01 lux before IR kicks in, and 120 dB WDR plus HLC and BLC manage headlights and backlit entrances. Night footage under IR is black and white.
Does it have local storage and a microphone?
Yes to both. The microSD slot accepts cards up to 512 GB for on-camera recording — a backup when the recorder or link fails — and the built-in microphone adds audio in G.711U/G.711A at 64 Kbps. Note this model has no speaker, so audio is listen-only.
Which lens covers more, and what detection does it run?
The 2.8 mm sees 107° horizontally with 63 m detection; the 4.0 mm sees 91.2° with 90 m detection and 9 m identification versus 6.3 m. Alarms include cross-line and intrusion based on human body detection, plus motion, tampering and audio detection — practical filtering for busy streets.
Will my existing NVR record the 8 MP stream of the IPC2128LB-ADF28(40)K-G?
Only if the NVR accepts 8 MP (3840 × 2160) cameras and decodes H.265; many older or budget NVRs stop at 5 or 6 MP, so check the NVR's maximum camera resolution first. For non-Uniview NVRs the camera supports ONVIF Profile S, G and T plus RTSP; video works, while the human-based cross-line/intrusion events and audio may be limited on other brands. If your NVR is limited to a lower resolution, you can set the camera's main stream to 5 MP (2880 × 1620). Tell us your NVR model and we will confirm before you order.
How much storage does the IPC2128LB-ADF28(40)K-G need at 8 MP?
It depends on the bit rate you set (128 Kbps to 16 Mbps). At the 16 Mbps maximum with continuous recording one camera writes about 172.8 GB per day: about 5.2 TB of NVR disk for 30 days, or about 3 days on a 512 GB microSD card. At 8 Mbps it is about 86.4 GB per day, about 2.6 TB for 30 days or about 5.9 days on 512 GB. Ultra 265 and event-only recording reduce these figures considerably.
What PoE switch and network do I need for several IPC2128LB-ADF28(40)K-G cameras?
Any IEEE 802.3af (or 802.3at) port powers it: max. 5.0 W per camera, so 8 cameras need about 40 W of PoE budget. The camera port is 10/100 Mbps, which is plenty for one camera, but 8 cameras at the 16 Mbps maximum add up to about 128 Mbps, more than a 100 Mbps uplink can carry, so use a PoE switch with a gigabit uplink to the NVR. Use Cat5e or Cat6 copper up to 100 m per run, and the sub stream (720P or lower) for phone viewing over slow internet.
Should I record the IPC2128LB-ADF28(40)K-G at 8 MP / 15 fps or 5 MP / 25 fps?
For most scenes keep 8 MP: 15 fps is normal for surveillance of people walking, and the extra pixels give more detail when you zoom into a recording. Choose 5 MP (2880 × 1620) at up to 25 fps where things move fast, such as vehicles at a gate, or when your NVR or bandwidth cannot handle 8 MP. In both cases the view angle stays the same; only the detail per meter changes.
What is the difference between the IPC2128LB-ADF28(40)K-G and the IPC2128LE-ADF28(40)KM-H?
Both are 8 MP fixed-lens PoE bullets with 2.8 mm or 4.0 mm lenses, 120 dB WDR, a built-in mic, microSD up to 512 GB and human-based cross-line/intrusion alerts. The IPC2128LB-ADF28(40)K-G is the smaller, lower-power one: 30 m IR, 8 MP at 15 fps, max. 5.0 W, 161 mm long. The IPC2128LE-ADF28(40)KM-H has 50 m IR, 8 MP at 20 fps and longer published DORI distances (identify 8.7 m / 12.4 m), at max. 6.9 W and 190 mm long. Choose the LE for larger yards and long fence lines at night; the LB where 30 m of IR is enough.
