The Uniview IPC2122LB-AF28(40)K-DL is a 2MP HD ColorHunter fixed mini bullet network camera with dual-light illumination. It combines 30 m infrared and 30 m warm-light illumination for discreet black-and-white or full-color night vision, powers over a single PoE cable, and carries an IP67 outdoor rating with a −30 °C to 60 °C working range. It is offered with two fixed lenses: 2.8 mm (AF28K, wider view) or 4.0 mm (AF40K, 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 & storefrontsSee who enters, and the built-in mic records what is said at the counter. AF28K covers the whole shop floor from a corner.
Home gates & yardsThe warm light turns on at night — visitors are visible in color and intruders know they are seen.
Warehouse & site perimetersIP67 body and −30 to 60 °C rating survive rain, dust and heat. AF40K watches long fence lines.
Residential compoundsHuman body detection raises alerts for people, not for stray animals or moving branches.
Small offices & receptionUltra 265 compression keeps recordings small — more days of footage on the same NVR disk.
Kiosks & fuel stationsOne PoE cable does power + video — no electrician needed at the pole, quick to install and move.
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)
- Alarm in/out wiring for sirens or sensors

IR MODE
Invisible infrared — discreet black & white night vision
Smart IR up to 30 m (98.4 ft.) at 850 nm. The camera watches without lighting up the scene — nothing shows it is recording.
WARM LIGHT MODE
Visible warm light — full-time color and active deterrence
Warm white light up to 30 m (98.4 ft.) keeps faces and clothing colors visible at night — and tells intruders the area is watched.

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 | AF28K · 2.8 mm · 101.1° | AF40K · 4.0 mm · 83.7° |
|---|---|---|
| 5 m16 ft | 12.2 m39.9 ft | 9.0 m29.4 ft |
| 10 m33 ft | 24.3 m79.7 ft | 17.9 m58.8 ft |
| 15 m49 ft | 36.5 m120 ft | 26.9 m88.2 ft |
| 20 m66 ft | 48.6 m159 ft | 35.8 m118 ft |
| 30 m98 ft | 72.9 m239 ft | 53.7 m176 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 IPC2122LB-AF28(40)K-DL from its own specifications: 2 MP, 2.8 mm or 4.0 mm F1.6 fixed lens, dual light (30 m IR + 30 m warm light), PoE 4.5 W, IP67.
Who it is for
- Homes, gates and yards — Switch to the 30 m warm light for color video at night, so clothing and car colors are on record, and anyone at the gate can see the area is watched. Switch back to IR when the light would disturb.
- Shops and small offices — The 2.8 mm version covers 12.2 m of width from 5 m away, enough for a whole shop floor from one corner; the built-in mic records sound at the counter.
- Kiosks, fuel stations and car parks — Max. 4.5 W on IEEE 802.3af PoE, so one cable brings power and video to a pole; the sodium-lamp white balance mode keeps colors natural under orange street lighting.
- Installers adding cameras to an existing NVR — ONVIF Profile S/G/T and RTSP for Uniview or third-party recorders, and a 4-language web interface (English, Russian, Spanish, Vietnamese).
Where and how to install
- Height and angle — Mount at about 2.5–3.5 m with a shallow downward tilt. Lower is easy to tamper with; much higher shows the top of heads instead of faces.
- Faces need a choke point — Aim at a door or gate where people walk toward the camera, within the identify distance: 4.5 m with the 2.8 mm lens, 6.4 m with the 4.0 mm lens.
- Keep the light path clear — Do not mount tight under eaves, beside a wall that is in the picture, or behind glass: both the IR and the warm light reflect back and wash out the image. Do not aim the warm light at a neighbor's windows.
- Backlight needs careful placement — This model has digital WDR (DWDR), not true WDR. Do not aim it straight out of a dark room through a bright doorway or at the setting sun; mount it outside facing in, or use HLC/BLC.
- Weather, cable and surge — The body is IP67, but the RJ45 and 12 V tail are not: put them in the TR-JB05-B-IN junction box and seal the conduit entry with the TR-A01-IN NPT 3/4" gland. Surge protection is 4 kV; on poles or long outdoor runs add a surge protector and earthing.
- Brackets — Pole: TR-UP06-C-IN-V2, which fits the junction box only, so order it together with TR-JB05-B-IN; building corner: TR-UC08-C-V2. Image flip is limited to normal, vertical, horizontal and 180°, so there is no 9:16 corridor view.
2.8 mm or 4.0 mm: what you actually see
Same 2 MP sensor, different lens. The 4.0 mm sees about 1.4× farther (identify 6.4 m vs 4.5 m) but covers about three quarters of the width. At 10 m it puts about 107 pixels on every meter of the scene versus about 79 for the 2.8 mm. At night both are limited by the 30 m light range.
| AF28K · 2.8 mm | AF40K · 4.0 mm | |
|---|---|---|
| Horizontal view angle | 101.1° | 83.7° |
| Width covered at 5 m | 12.2 m | 9.0 m |
| Width covered at 10 m | 24.3 m | 17.9 m |
| Pixels per meter at 10 m | 79 | 107 |
| Identify a stranger's face up to | 4.5 m | 6.4 m |
| Recognize someone you know up to | 9.0 m | 12.9 m |
| Detect that something is there up to (daytime) | 45.0 m | 64.3 m |
| IR / warm light range at night | 30 m | 30 m |
- Pick 2.8 mm for a shop floor, porch or small yard: from 5 m away it covers 12.2 m of width.
- Pick 4.0 mm for a gate or driveway where faces matter at 5–6 m: it identifies a face at 6.4 m.
- For a long fence at night, plan cameras every 30 m or less whichever lens you choose: the 64.3 m detect figure is daytime only.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = 1920 ÷ width at 10 m; face and detect distances are the manufacturer's DORI figures.

2MP Dual-Light Bullet Camera FAQ — IPC2122LB-AF28(40)K-DL
How does night vision work on the IPC2122LB-AF28(40)K-DL?
It carries two illuminators, both rated to 30 m: invisible 850 nm IR for discreet black-and-white monitoring, and warm white light that keeps faces and clothing colors visible. The F1.6 ColorHunter optics work down to 0.005 lux in color before any light is needed.
Which lens version fits my site, 2.8 mm or 4.0 mm?
The 2.8 mm (AF28K) gives a 101.1° view, detecting at 45 m and identifying at 4.5 m — suited to yards, forecourts and shop fronts. The 4.0 mm (AF40K) tightens to 83.7° with detection at 64.3 m and identification at 6.4 m for driveways and longer approaches.
Can it alert me when a person shows up, not just any motion?
Yes — human body detection is built in alongside motion and audio detection, so alerts key on human shapes in the frame. That cuts nuisance notifications from pets, birds and moving branches, which matters when a guard post or phone receives every event.
Is it OK outdoors and how is it powered?
The mini bullet housing is IP67 rated against dust and rain, and power is PoE — one network cable from the switch or NVR carries everything. The bracket adjusts 0-360 degrees pan and 0-90 degrees tilt, and the built-in microphone captures audio at the scene.
What video quality and bandwidth does it produce?
Main stream is 1080P (1920×1080) at up to 30 fps in Ultra 265, H.265 or H.264, with U-code available on the main stream for extra compression. Bit rate adjusts from 128 to 6144 Kbps, and dual streams keep recording and live phone viewing separate.
Does the warm light on the IPC2122LB-AF28(40)K-DL switch on only when a person appears?
The specifications list two night modes, IR or warm light, with Auto/Manual control; a mode that keeps IR on and turns the warm light on only when a person is detected is not listed for this model. Plan on choosing IR or warm light per camera (or switching manually). If person-triggered light is a must for your project, ask us before ordering and we will confirm with the current firmware.
IPC2122LB-AF28(40)K-DL or IPC2122LB-ADF28(40)KM-H: which one for a backlit entrance?
For a glass door or a doorway with bright sky behind it, the IPC2122LB-ADF28(40)KM-H is the better choice because it has 120 dB true WDR, while this model has digital WDR only. This model is the better choice where night color matters: it adds 30 m warm light and a brighter F1.6 lens with 0.005 Lux color sensitivity. Both are 2 MP with mic, PoE and IP67.
Will the IPC2122LB-AF28(40)K-DL work with a Hikvision, Dahua or other non-Uniview NVR?
Usually yes for video: it supports ONVIF Profile S, G and T plus RTSP, which most third-party NVRs and VMS software use to add cameras. Live view and recording work over ONVIF; human body detection alarms and the IR/warm light setting are fully handled on Uniview NVRs, while on other brands you may need to set the light mode in the camera's own web page. Tell us your NVR model and we will confirm before you order.
How many days of recording fit on a microSD card or NVR disk with the IPC2122LB-AF28(40)K-DL?
At the maximum bit rate of 6144 Kbps with continuous recording it writes about 66.4 GB per day: about 3.9 days on a 256 GB card, 7.7 days on the maximum 512 GB card, and about 2 TB of NVR disk per camera for 30 days. At 2048 Kbps with Ultra 265 the same 512 GB card lasts about 23 days. Warm-light color video at night usually needs a little more bit rate than black-and-white IR, so leave some margin.
Does the IPC2122LB-AF28(40)K-DL record sound, and can I talk back through it?
It records sound but you cannot talk back. The built-in mic sends G.711 audio at 64 Kbps with the video, and audio detection can raise an alarm on loud noise. There is no speaker, no audio input/output terminal and two-way audio is listed as N/A. Check local law before recording conversations in shops or offices.
