It delivers 120 dB true WDR for high-contrast scenes, Smart IR up to 30 m (98.4 ft.), single-cable PoE power, and an IP67 outdoor-rated body built for a −30 °C to 60 °C working range. It is offered with two fixed lenses: 2.8 mm (ADF28KM, wider view) or 4.0 mm (ADF40KM, 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. ADF28KM covers the whole shop floor from a corner.
Backlit entrances & glass fronts120 dB true WDR keeps faces visible even against bright daylight or glass reflections.
Warehouse & site perimetersIP67 body and −30 to 60 °C rating survive rain, dust and heat. ADF40KM watches long fence lines.
Residential compoundsCross line and intrusion alerts are based on human body detection, so stray animals or moving branches do not trigger false alarms.
Corridors & narrow hallways9:16 corridor mode reframes the image to match tall, narrow spaces instead of wasting pixels on walls.
Small offices & receptionUltra 265 compression keeps recordings small, and a MicroSD slot up to 512 GB backs up footage even if the network drops.
Not the right pick if you need…
- Color night vision — this is IR-only; it switches to black & white in low light
- 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

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 | ADF28KM · 2.8 mm · 112.9° | ADF40KM · 4.0 mm · 91.2° |
|---|---|---|

| 30 m98 ft | 90.5 m297 ft | 61.3 m201 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-ADF28(40)KM-H from its own specifications: 2 MP, 2.8 mm or 4.0 mm fixed lens, 120 dB true WDR, Smart IR 30 m, PoE 3.8 W, IP67.
Who it is for
- Installers on a budget, many cameras per job — Max. 3.8 W on IEEE 802.3af PoE, ONVIF Profile S/G/T for Uniview or third-party NVRs, and one cable per camera. The web interface is in 4 languages: English, Russian, Spanish and Vietnamese.
- Shops with glass fronts and bright doorways — 120 dB true WDR keeps faces readable against daylight behind the door, and the built-in mic records what is said at the counter.
- Warehouses, yards and compounds — IP67 body rated −30 °C to 60 °C; cross line and intrusion alarms are based on human body detection, so animals and moving branches cause fewer false alarms. The 4.0 mm version reaches farther along fences.
- Offices, corridors and stairwells — 9:16 corridor mode fits tall, narrow spaces, and a microSD card up to 512 GB keeps recording at the camera if the link to the NVR drops (ANR).
Where and how to install
- Height and angle — Mount at about 2.5–3.5 m with a shallow downward tilt. The 3-axis bracket (tilt 0–90°, rotate 0–360°) lets you level the image even on a sloped wall.
- Faces need a choke point — Aim at a door, gate or corridor where people walk toward the camera, within the identify distance: 4.2 m with the 2.8 mm lens, 6.0 m with the 4.0 mm lens.
- Keep the IR clear — Do not mount tight under eaves, close to a wall that is in the picture, or behind window glass: the 850 nm IR reflects back and the night image turns white or foggy. Keep branches and cables out of the first metre in front of the lens.
- Night range is set by the IR — The detect distances (42 m / 60 m) are daytime lens figures; in darkness the camera sees only as far as its 30 m IR. Plan night coverage of long fences within 30 m, or add yard lighting.
- 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 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-B-IN, or TR-UP06-C-IN-V2 when you use the junction box; building corner: TR-UC08-C-V2. For hallways, turn the camera 90° and use the 9:16 corridor mode.
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 6.0 m vs 4.2 m) but covers about two thirds of the width. At 10 m it puts about 94 pixels on every meter of the scene versus about 64 for the 2.8 mm.
| ADF28KM · 2.8 mm | ADF40KM · 4.0 mm | |
|---|---|---|
| Horizontal view angle | 112.9° | 91.2° |
| Width covered at 5 m | 15.1 m | 10.2 m |
| Width covered at 10 m | 30.2 m | 20.4 m |
| Pixels per meter at 10 m | 64 | 94 |
| Identify a stranger's face up to | 4.2 m | 6.0 m |
| Recognize someone you know up to | 8.4 m | 12.0 m |
| Detect that something is there up to (daytime) | 42.0 m | 60.0 m |
| IR range at night | 30 m | 30 m |
- Pick 2.8 mm for a shop floor, reception or small yard seen from a corner: from 5 m away it covers 15.1 m of width.
- Pick 4.0 mm for a gate, driveway or corridor where faces matter at 5–6 m, or a fence line: it identifies a face at 6.0 m.
- At 2 MP neither lens gives face detail far away; for faces beyond 6 m, add a second camera closer to the entrance rather than relying on one wide view.
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 WDR Bullet Camera FAQ — IPC2122LB-ADF28(40)KM-H
Which lens option should I pick for the IPC2122LB-ADF28(40)KM-H?
The 2.8 mm (ADF28KM) covers 112.9° horizontally and detects a person at 42 m — pick it for wide, close scenes like forecourts. The 4.0 mm (ADF40KM) narrows to 91.2° but detects at 60 m and identifies at 6 m versus 4.2 m, better for driveways and passages.
What does 120 dB true WDR actually do for me?
It exposes bright and dark parts of the frame separately, so a doorway looking out into strong sunlight shows both the lit street and the person stepping inside. Without it, backlit subjects become silhouettes. HLC and BLC add headlight and backlight correction on top.
How far does it see at night?
Smart IR at 850 nm reaches 30 m with auto or manual control, and the IR-cut filter switches to black-and-white in the dark. In color the sensor works down to 0.01 lux at F2.0, so areas under street or compound lighting hold color into the night.
Does it have people-based perimeter detection?
Yes — cross-line detection is based on human body detection, so a rule drawn along a wall or gate fires on people, not stray animals or shadows. Ultra motion detection, standard motion detection, tampering alarm and audio detection complete the alert options.
How is it powered and mounted outdoors?
PoE carries power and video on one network cable from your switch or NVR. The IP67 bullet housing is sealed against dust and rain, the bracket adjusts 0-360 degrees pan and 0-90 degrees tilt, and a built-in microphone records audio without extra wiring.
How much bandwidth does each camera need?
Main stream is 1080P at up to 30 fps with the bit rate adjustable between 128 and 6144 Kbps. Ultra 265 plus U-code compression pull the average well down on quiet scenes, and dual streams mean remote phone viewing rides the lighter sub stream.
Will the IPC2122LB-ADF28(40)KM-H 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; the human-body-based cross line and intrusion alarms and the corridor mode settings are fully supported on Uniview NVRs and may show up only as plain motion events, or not at all, on other brands. 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-ADF28(40)KM-H?
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, which is often enough for 1080P with Ultra 265, the same 512 GB card lasts about 23 days. Event-only recording stretches it further.
Why is the night image white, foggy or full of false alarms on my IPC2122LB-ADF28(40)KM-H?
Almost always it is IR bouncing back: a wall, eave, pole or glass close to the lens, a spider web, or rain drops on the front window reflect the 850 nm light. Move or re-aim the camera so nothing sits right in front of it, never install it behind glass, and clean webs during maintenance. For alarms, use cross line or intrusion (both based on human body detection) instead of plain motion detection, which reacts to insects flying through the IR beam.
Does the IPC2122LB-ADF28(40)KM-H 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 trigger 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.
Can I view the IPC2122LB-ADF28(40)KM-H on a PC or phone without an NVR?
Yes. Open its IP address in Chrome 57+, Firefox 58+ or Edge 16+ for plug-in-free live view, or use the EZStation PC client; the page lists an APP for phones. Insert a microSD card (up to 512 GB) so it records on its own. Up to 32 user accounts can be created, with administrator and common user levels, so the owner and staff can have separate logins.
