The Uniview IPC2124LE-ADF28(40)KM-H is a 4MP fixed-lens mini IR bullet network camera built around a 1/3.0" CMOS sensor with 120dB true WDR and Easystar low-light technology. Smart IR reaches up to 50m (164.0 ft.), the body carries an IP67 outdoor rating with a −30°C to 60°C working range, and it runs on PoE (802.3af) or DC 12V with a built-in mic and a MicroSD slot up to 512GB. Two fixed lenses are offered: 2.8mm (ADF28KM, 97.0° horizontal view) or 4.0mm (ADF40KM, 79.0° horizontal view).
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Shops & storefrontsThe built-in mic records what is said at the counter, and ADF28KM's 97.0° view covers the whole shop floor from a corner.
Home gates & yardsSmart IR up to 50m keeps the entrance visible at night, and the tampering alarm flags anyone who tries to cover or move the camera.
Warehouse & site perimetersIP67 body and −30 to 60 °C rating survive rain, dust and heat. ADF40KM's narrower 79.0° view watches long fence lines.
Residential compoundsCross-line and intrusion alerts are based on human body detection, not plain motion — fewer false alarms from stray animals or moving branches.
Small offices & receptionUltra 265 compression plus a MicroSD slot up to 512GB means it can hold its own recordings even without an NVR on site.
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)
- Vandal-resistant housing — this is IP67 weatherproof, not IK-rated impact-resistant
- 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 · 97.0° | KM · 79.0° |
|---|---|---|
| 5 m16 ft | 11.3 m37.1 ft | 8.2 m27.0 ft |

| 30 m98 ft | 67.8 m222 ft | 49.5 m162 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 IPC2124LE-ADF28(40)KM-H from its own specifications: 4 MP (2688 × 1520), 2.8 mm or 4.0 mm F1.6 fixed lens, 50 m Smart IR, 120 dB WDR, built-in mic and microSD, PoE at max. 5.6 W.
Who it is for
- Security installers and integrators — One 802.3af PoE cable per camera at max. 5.6 W, ONVIF Profile S/G/T for Uniview or third-party NVRs, a reset button, and a 13-language web interface for handover.
- Gates, entrances and backlit doors — 120 dB true WDR keeps faces readable against bright daylight, and the 4.0 mm version identifies a face up to 9.0 m away.
- Yards, compounds and fence lines — Smart IR reaches 50 m at night, and cross line and intrusion based on human body detection alert on people rather than animals or branches.
- Shops and small offices — The 2.8 mm version covers 97.0° from a corner; the built-in mic records sound (there is no speaker), and a microSD card up to 512 GB keeps recordings without an NVR.
- 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 — The 50 m, 850 nm IR is strong: eaves, walls, gutters or branches close to the lens reflect it and turn the picture white at night. Keep them out of the frame and do not mount tight under a roof edge.
- Corridors and aisles — For hallways, warehouse aisles or a narrow side passage, turn the image 90° and use the 9:16 corridor mode so the frame matches the tall, narrow space instead of filming walls.
- Brackets and junction box — Hide the RJ45 and 12 V tail in the TR-JB05-B-IN junction box with the TR-A01-IN cable gland. On a pole use TR-UP06-C-IN-V2 together with the junction box; on a building corner use TR-UC08-C-V2.
- Weather and surge — The body is IP67 for −30 °C to 60 °C, 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 163 pixels on every meter of the scene versus about 119 for the 2.8 mm.
| ADF28KM · 2.8 mm | ADF40KM · 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 | ≈119 px/m | ≈163 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 11.3 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 range is the same for both: Smart IR lights up to 50 m, so the 4.0 mm can use its longer reach after dark too.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = 2688 ÷ width at 10 m; face distances are the manufacturer's DORI figures.

4MP 50m IR Bullet Camera FAQ — IPC2124LE-ADF28(40)KM-H
How far does the IR reach on the IPC2124LE-ADF28(40)KM-H?
Smart IR reaches up to 50 m (164 ft) at 850 nm — noticeably farther than the 30 m typical of mini bullets — while automatically lowering LED power for close subjects so faces near the camera are not washed out. With IR on, it works down to 0 lux.
Will it handle a gate where the camera faces bright sunlight?
Yes. True 120 dB WDR balances dark interiors against bright exteriors in the same frame, and HLC suppresses vehicle headlights at night. The F1.6 lens with 0.003 lux color sensitivity keeps evening scenes usable, with BLC, digital defog and 2D/3D noise reduction on top.
Does it alert only on people, or on every movement?
You choose. Cross-line and intrusion alarms are based on human body detection, filtering out animals, vehicles passing and wind-blown vegetation, while classic motion detection, ultra motion detection, tampering and audio detection remain available for general coverage. That mix keeps night alerts meaningful on perimeter walls.
Which lens do I need, 2.8 mm or 4.0 mm?
The 2.8 mm (ADF28KM) gives 97° horizontal coverage with 63 m detection and 6.3 m identification — suited to entrances and yards. The 4.0 mm (ADF40KM) narrows to 79° but stretches to 90 m detection and 9 m identification — suited to lanes and fence lines.
What resolution does it record and is it NDAA compliant?
The main stream reaches 4 MP (2688×1520) at up to 25 fps, with 3 MP and 1080p options at 30 fps, in Ultra 265, H.265, H.264 or MJPEG at 128 Kbps to 6144 Kbps. And yes — this model is NDAA compliant, so it fits restricted tenders.
Will the IPC2124LE-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; human-based cross line and intrusion, audio and ANR 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 IPC2124LE-ADF28(40)KM-H?
Any IEEE 802.3af (or 802.3at) PoE port works: the camera draws at most 5.6 W, so 8 cameras need only about 44.8 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 IPC2124LE-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 IPC2124LE-ADF28(40)KM-H keep recording if the cable to the NVR is cut or the network drops?
Yes, if a microSD card is fitted (up to 512 GB) and the camera still has power, for example from a separate 12 V DC supply when the PoE switch is down. With ANR enabled on the camera and a Uniview NVR, the NVR copies the missing footage back from the card when the link returns. With PoE only, a cut cable also cuts power, so put the switch and NVR on a UPS.
What does the IPC2124LE-ADF28(40)KM-H add over the IPC2124LB-ADF28(40)KM-H?
Mainly night and low-light performance: this LE model has a brighter F1.6 lens with Easystar (colour down to 0.003 lux) and Smart IR up to 50 m, against 30 m on the LB model. It also records up to 2688 × 1520, has a 9:16 corridor mode, a reset button and a 13-language web interface. Both have 120 dB WDR, a built-in mic, microSD and human-body-based cross line and intrusion, so the LB is enough where 30 m of IR covers the area.
