The Uniview IPC2124LB-ADF28(40)KM-H is a 4MP mini fixed bullet network camera with a 1/3.0" CMOS sensor and 120 dB WDR. Smart IR reaches up to 30 m (98.4 ft.), it powers over a single PoE cable, and it carries an IP67 rating for outdoor use across a −30 °C to 60 °C working range. It ships with a built-in mic, microSD edge storage up to 512 GB, and a choice of 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 & storefronts4MP detail plus a built-in mic with audio detection can flag raised voices at the counter. ADF28KM's 101.5° view covers the whole shop floor from a corner.
Home gates & drivewaysSmart IR sees up to 30 m at night in black & white. ADF40KM's narrower 84.1° 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. The microSD slot (up to 512 GB) and ANR network storage keep footage even if the link to the NVR drops.
Narrow aisles & hallwaysCorridor Mode rotates the image 90° clockwise or anti-clockwise, turning the wide frame into a tall one that fits narrow hallways and aisles.
Government & critical-infrastructure projectsThe camera is NDAA compliant, relevant for procurement that requires equipment from non-restricted sources.
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 — 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)
- 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 | KM · 101.5° | KM · 84.1° |
|---|---|---|

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 IPC2124LB-ADF28(40)KM-H from its own specifications: 4 MP, 2.8 mm or 4.0 mm fixed lens, 30 m Smart IR, built-in mic, PoE at max. 4.1 W.
Who it is for
- Security installers and integrators — One 802.3af PoE cable per camera at max. 4.1 W, and ONVIF Profile S/G/T so it can be added to Uniview or third-party NVRs.
- Shops and small offices — The 2.8 mm version sees 101.5° wide, enough for a whole sales floor from one corner, and the built-in mic records sound with the video.
- Homes, gates and driveways — The 4.0 mm version identifies a face up to 9.0 m away, and cross line and intrusion based on human body detection alert on people rather than every moving shadow.
- Warehouses, yards and site perimeters — IP67 body for −30 °C to 60 °C, and ANR fills recording gaps from the microSD card (up to 512 GB) when the link to the NVR drops.
- Projects that require NDAA — The page lists this camera as NDAA compliant, which matters for tenders and buyers that exclude restricted sources.
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, gate or corridor 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.
- Keep the IR path clear — At night the 850 nm IR reflects off eaves, walls, gutters or branches close to the lens and turns the picture white. Keep these out of the frame and use the sun shield as fitted.
- Backlight and corridors — 120 dB WDR handles a bright doorway, but do not aim straight at the sun or at headlights. For hallways and aisles, rotate the image 90° (corridor mode) so the frame is tall and narrow.
- Brackets and junction box — Hide the RJ45 and 12 V tail in the TR-JB05-A-IN junction box with the TR-A01-IN cable gland. Pole: TR-UP06-B-IN, or TR-UP06-C-IN-V2 with the junction box. Building corner: TR-UC08-C-V2.
- Weather and surge — The body is IP67, but water still enters through an unprotected cable joint. Surge protection is 4 kV; on poles or long outdoor runs add a network surge protector and earthing.
2.8 mm or 4.0 mm: what you actually see
Same 4 MP sensor, different lens. The 4.0 mm reaches about 1.4× farther for the same detail but covers about a quarter less width. At 10 m it puts about 142 pixels on every meter of the scene versus about 104 for the 2.8 mm.
| ADF28KM · 2.8 mm | ADF40KM · 4.0 mm | |
|---|---|---|
| Horizontal view angle | 101.5° | 84.1° |
| Width covered at 5 m | 12.2 m | 9.0 m |
| Width covered at 10 m | 24.5 m | 18.0 m |
| Pixels per meter at 10 m | ≈104 px/m | ≈142 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 | 63.0 m | 90.0 m |
- Pick 2.8 mm for a shop floor, a small yard or a room seen from a corner: from 5 m away it covers 12.2 m of width.
- Pick 4.0 mm for a gate, driveway or corridor where faces matter at 7–9 m: identification still works at 9.0 m.
- Night limit is the same for both: Smart IR lights the scene up to 30 m, so detail beyond that is lost after dark whatever the lens.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = 2560 ÷ width at 10 m; face distances are the manufacturer's DORI figures.

4MP PoE Bullet Camera FAQ — IPC2124LB-ADF28(40)KM-H
What resolution and frame rate does the IPC2124LB-ADF28(40)KM-H record?
The main stream delivers 4 MP (2560×1440) at up to 25 fps, or 3 MP and 1080p at 30 fps if you prefer smoother motion. Compression options are Ultra 265, H.265, H.264 and MJPEG, with bit rate adjustable from 128 Kbps to 6144 Kbps over dual streams.
Can it record locally without an NVR?
Yes. A microSD slot takes cards up to 512 GB for edge recording, which suits small shops or remote sites where a full NVR is not justified — and acts as a backup if the network link to the recorder drops. The built-in microphone captures audio alongside video.
How far does the night vision reach?
Smart IR at 850 nm reaches up to 30 m (98.4 ft) and adjusts LED power automatically so nearby faces are not washed out. The light is invisible, images at night are black and white, and with IR on the camera works at 0 lux.
Which lens should I take for a compound wall, 2.8 mm or 4.0 mm?
For wide coverage near the camera take the 2.8 mm: 101.5° horizontal view, 63 m detection, 6.3 m identification. For longer walls or driveways take the 4.0 mm: 84.1° view but 90 m detection and 9 m identification. Both versions are otherwise identical.
Does it give false alarms with animals or moving trees?
Cross-line and intrusion alarms are based on human body detection, so wind-blown branches and small animals are filtered out far better than with plain motion detection. Motion detection, ultra motion detection, tampering alarm and audio detection are also available, and 120 dB WDR keeps detection reliable in harsh backlight.
Will the IPC2124LB-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 use to add cameras. Live view and recording work over ONVIF; smart events such as cross line and intrusion, and audio, are fully supported on Uniview NVRs and may be limited or missing on other brands. Tell us your NVR model and we will confirm before you order.
What PoE switch and cable do I need for the IPC2124LB-ADF28(40)KM-H?
Any IEEE 802.3af (or 802.3at) PoE port works: the camera draws at most 4.1 W, so 8 cameras need only about 32.8 W of PoE budget in total. Its network port is 10/100 Mbps, so Fast Ethernet PoE ports are enough; with many cameras use a gigabit uplink to the NVR (16 cameras at the 6144 Kbps maximum add up to about 98 Mbps). Use Cat5e or Cat6 copper cable up to 100 m per run, or a 12 V DC adapter with a Ø5.5 mm plug where there is no PoE.
How much NVR hard-disk space do I need for the IPC2124LB-ADF28(40)KM-H?
At the maximum bit rate of 6144 Kbps with continuous recording, one camera writes about 66.4 GB per day, or about 2 TB for 30 days. Assuming a more typical 4096 Kbps, 8 cameras need about 10.6 TB for 30 days of continuous recording. Ultra 265 at a lower bit rate, or recording only on events, cuts this sharply.
Does the IPC2124LB-ADF28(40)KM-H record sound, and can I talk through it?
It records sound from the built-in mic (G.711, 64 Kbps, 8 kHz) with noise suppression, and audio detection can trigger an alarm on loud sound. It cannot talk back: there is no built-in speaker, two-way audio and audio I/O are N/A, so an external speaker cannot be connected either. Check local law before recording audio in shops or workplaces.
How do I view the IPC2124LB-ADF28(40)KM-H on a PC or phone?
On a PC, open the camera's IP in Chrome 57+, Firefox 58+ or Edge 16+ for plug-in-free live view, or use the EZStation client for several cameras; the page also lists a mobile APP. The web interface is in 4 languages (English, Russian, Spanish, Vietnamese) and supports up to 32 users with administrator and common-user levels. For remote viewing, add it to a Uniview NVR or set it up in the app rather than opening ports on the router.
