The Uniview IPC2124LB-SF28(40)-A is a 4MP fixed IR mini bullet network camera with Smart IR night vision up to 30 m, PoE (802.3af) or DC 12 V power, and an IP67 outdoor-rated body for −30 °C to 60 °C operation. It ships with two fixed lens options: 2.8 mm (SF28, 97.0° wide view) or 4.0 mm (SF40, 79.0° longer-reach view). It supports Ultra 265/H.265/H.264 compression and HLC, and is NDAA compliant.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Shops & storefronts4MP resolution and SF28's 97.0° view catch fine detail across the whole shop floor from a corner; Ultra 265 keeps the recordings small.
Home gates & drivewaysSmart IR sees up to 30 m at night in black & white. SF40's narrower 79.0° 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. PoE or DC 12 V power gives installers a choice at the pole.
Government & critical-infrastructure projectsThe camera is NDAA compliant, relevant for procurement that requires equipment from non-restricted sources.
Small offices & multi-camera sitesUltra 265 compression and dual video streams keep bandwidth and NVR storage use low even at 4MP, across many cameras.
Backlit entrances & parking gatesHLC (highlight compensation) keeps faces and plates visible against headlights or strong backlight instead of a washed-out silhouette.
Not the right pick if you need…
- Two-way talk — no built-in microphone or speaker at all
- Wi-Fi — this is a wired RJ45 camera
- Zoom — the lens is fixed (2.8 or 4.0 mm, chosen at purchase)
- MicroSD card recording — it records to an NVR, no local storage slot
- 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 | SF28 · 97.0° | SF40 · 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 IPC2124LB-SF28(40)-A from its own specifications: 4 MP, 2.8 mm or 4.0 mm fixed lens, 30 m Smart IR, PoE or DC 12 V at max. 5.0 W, IP67, no mic or microSD.
Who it is for
- Security installers and integrators — A plain 4 MP bullet for NVR systems: PoE 802.3af or DC 12 V at max. 5.0 W, and ONVIF Profile S/T for Uniview or third-party NVRs.
- Sites where audio must not be recorded — There is no built-in mic and no audio input, so it cannot record conversations: useful for offices, clinics and workplaces where audio recording is restricted.
- Homes, gates and parking entrances — The 4.0 mm version identifies a face up to 9.0 m away, and HLC holds back headlight glare at gates at night.
- Multi-camera shops, offices and warehouses — Ultra 265 and dual streams keep NVR disk and network use low, and the 2.8 mm version covers 97.0° from a corner.
- 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 needs careful placement — This model has digital WDR (DWDR) plus HLC and BLC. Do not aim it from inside out through a glass door; place it so bright daylight is to the side, and use HLC at gates where headlights shine into the lens.
- 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 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 155 pixels on every meter of the scene versus about 113 for the 2.8 mm.
| SF28 · 2.8 mm | SF40 · 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 | ≈113 px/m | ≈155 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 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-SF28(40)-A
How can I power the IPC2124LB-SF28(40)-A?
Two options: PoE over the network cable from a PoE switch or injector, or a local DC12V supply. PoE is the cleaner install — one cable per camera — while DC12V helps when reusing existing power wiring or connecting to a nearby adapter. The IP67 body suits outdoor mounting.
Is it compatible with third-party NVRs over ONVIF?
Yes. It supports ONVIF Profile S and Profile T plus API and SDK integration, and speaks RTSP, RTMP, HTTPS, QoS and SSL/TLS among other protocols. Most third-party NVRs and VMS platforms will discover it and pull both streams. Up to 32 users across three permission levels are supported.
What is the night vision distance?
Smart IR covers up to 30 m (98.4 ft) at 850 nm. The light is invisible to the eye, so the camera stays discreet at night; images are black and white and the sensor works down to 0 lux with IR on. LED power self-adjusts to protect close-up detail.
What is the difference between the 2.8 mm and 4.0 mm versions?
Only the lens. The 2.8 mm (SF28) sees 97° horizontally, detects people at 63 m and identifies at 6.3 m. The 4.0 mm (SF40) sees 79° but detects at 90 m and identifies at 9 m. Wide scene close by: 2.8 mm. Long reach down a fence or lane: 4.0 mm.
How much bandwidth does the 4MP stream take on my network?
You set the bit rate between 128 Kbps and 6144 Kbps. The main stream runs 4 MP (2560×1440) at up to 25 fps in Ultra 265, H.265 or H.264, and U-code trims it further on quiet scenes. Dual streams keep remote viewing light while the NVR records full resolution.
What happens to recording if the NVR or network goes down with the IPC2124LB-SF28(40)-A?
Recording stops: this model has no microSD slot and no edge storage, so it only records to an NVR or other recorder over the network. Put the NVR and the PoE switch on a UPS, protect outdoor cable runs, and keep the NVR in a locked place. If you need the camera to keep recording on its own, choose a version with microSD, such as the IPC2124LB-ASF28(40)K-A.
How much NVR hard-disk space do I need for the IPC2124LB-SF28(40)-A?
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.
Can the IPC2124LB-SF28(40)-A record sound if I add a microphone?
No. It has no built-in mic, no speaker and no audio input or output, so there is nowhere to connect an external microphone. If audio is needed, use a model with a built-in mic, for example the IPC2124LB-ASF28(40)K-A, or a separate audio device on the NVR side if your NVR supports it.
Will the IPC2124LB-SF28(40)-A send false alarms from trees, rain or animals?
It can: the only event listed is plain motion detection, with no human or vehicle classification. Draw the motion area only over the path or door, lower the sensitivity, keep moving branches and road traffic out of the frame, and keep the IR area free of spider webs. If you need alarms only on people, ask us for a model with human-body-based detection, such as the IPC2124LB-ADF28(40)KM-H.
How many IPC2124LB-SF28(40)-A cameras can one PoE switch run?
Check the switch's total PoE budget: each camera draws at most 5.0 W, so 4 cameras need about 20 W and 8 cameras about 40 W, plus some margin. Each port must support IEEE 802.3af, and a 10/100 Mbps port is enough because the camera's own port is 10/100 Mbps. Keep each copper run within 100 m.
