The Uniview IPC3612LB-SF28(40)-A is a 2MP fixed dome network camera. Smart IR reaches up to 30 m for night vision, it powers over a single PoE cable, and it carries an IP67 outdoor rating with a −30 °C to 60 °C working range. It is offered with two fixed lenses: 2.8 mm (SF28, wider view) or 4.0 mm (SF40, 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 & storefrontsThe compact turret dome mounts flush on a ceiling or wall to watch the door and counter. SF28 covers the whole shop floor from a corner.
Home entryways & gatesSmart IR keeps watch at night without lighting up the scene — discreet black & white night vision up to 30 m.
Warehouse & site perimetersIP67 body and −30 to 60 °C rating survive rain, dust and heat. SF40 watches long fence lines.
Hallways & corridorsThe turret dome shape is a familiar, low-profile fit for indoor or covered-outdoor ceiling mounting along corridors.
Small offices & receptionUltra 265 compression keeps recordings small — more days of footage on the same NVR disk.
Retail aisles & parking areasOne PoE cable does power + video — no electrician needed at the mounting point, quick to install.
Not the right pick if you need…
- Two-way talk — no built-in microphone or speaker at all
- Color night vision — infrared only, there is no visible warm-light illuminator
- 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 | AF28 · 101.1° | AF40 · 82.5° |
|---|---|---|
| 5 m16 ft | 12.2 m39.9 ft | 8.8 m28.8 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 IPC3612LB-SF28(40)-A from its own specifications: 2 MP dome, 2.8 mm or 4.0 mm fixed lens, Smart IR 30 m, PoE max 5.0 W, IP67, no MicroSD slot and no mic.
Who it is for
- Installers on NVR projects — A low-cost 2 MP camera for many points on one NVR: 5.0 W per PoE port, Ultra 265 to save disk, ONVIF Profile S/T for Uniview or third-party recorders, and listed as NDAA compliant on this page.
- Shops, offices and reception areas — The SF28 (2.8 mm, 101.1°) covers a whole small room or shop floor from a corner ceiling, in a low-profile dome that blends into the ceiling.
- Corridors, warehouses and driveways — The SF40 (4.0 mm, 82.5°) reaches farther: it identifies a face up to 6.2 m and recognizes a known person up to 12.4 m, for aisles, fence lines and parking lanes.
- Homes that want discreet night vision — 850 nm Smart IR up to 30 m gives black-and-white night video without lighting up the yard or bothering neighbors.
Where and how to install
- Height and angle — Mount at about 2.5–3.5 m on a wall or ceiling and use the 3-axis adjustment (tilt 0–80°) to keep the downward angle shallow. Too high and you see the tops 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: 4.5 m with the 2.8 mm lens, 6.2 m with the 4.0 mm lens.
- Avoid IR reflections — A nearby eave, wall or ceiling edge inside the picture reflects the IR back and turns the night image white. Leave clear space in front of the dome, keep the dome cover clean and unscratched, and never mount it behind window glass.
- Backlight at doorways — This model has digital WDR (DWDR) plus BLC and HLC, not true 120 dB WDR. Do not aim from inside straight out through a bright doorway; mount it outside facing in, or at an angle to the opening.
- Weather, cable and surge — The body is IP67 and works from -30 °C to 60 °C, but the RJ45 and 12 V tail must be protected: use the TR-JB03-I-IN junction box (wiring from behind) or a TR-A01-IN cable gland. Surge protection is 4 kV; on poles or long outdoor runs add a surge protector and earthing.
- Brackets — Ceiling: mount directly, or TR-CM24-IN with a TR-SE24-IN (200 mm) or TR-SE24-A-IN (500 mm) pendant pole for high indoor ceilings. Wall: TR-WM03-D-IN-V2, TR-JB07/WM03-G-IN-V2 or the plastic TR-WM07P-B; building corner: TR-UC08-C-V2.
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 6.2 m vs 4.5 m) but covers only about 72% of the width. At 10 m it puts about 109 pixels on every meter of the scene versus about 79 for the 2.8 mm.
| SF28 · 2.8 mm | SF40 · 4.0 mm | |
|---|---|---|
| Horizontal view angle | 101.1° | 82.5° |
| Width covered at 5 m | 12.2 m | 8.8 m |
| Width covered at 10 m | 24.3 m | 17.5 m |
| Pixels per meter at 10 m | ≈ 79 px/m | ≈ 109 px/m |
| Identify a stranger's face up to | 4.5 m | 6.2 m |
| Recognize someone you know up to | 9 m | 12.4 m |
| Observe what is happening up to | 18 m | 24.8 m |
| Detect that something is there up to | 45 m | 64.3 m |
| IR distance | 30 m | 30 m |
- Pick SF28 (2.8 mm) for a shop, office, garage or small yard seen from a corner: from 5 m away it covers 12.2 m of width.
- Pick SF40 (4.0 mm) for a corridor, gate or driveway 5–6 m from the camera where faces matter: identify up to 6.2 m.
- At night both reach 30 m with IR, but past about 18 m (2.8 mm) or 24.8 m (4.0 mm) you only see that something is happening.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = 1920 ÷ width; DORI distances are the manufacturer's figures.

2MP Fixed Dome Camera FAQ — IPC3612LB-SF28(40)-A
Which lens should I pick: SF28 (2.8 mm) or SF40 (4.0 mm)?
The 2.8 mm version covers 101.1 degrees horizontally with DORI detection at 45 m and identification at 4.5 m — good for rooms and close entries. The 4.0 mm version narrows to 82.5 degrees but stretches detection to 64.3 m and identification to 6.2 m.
How does it perform at night?
Smart IR covers up to 30 m at 850 nm, switchable Auto or Manual, with no visible glow. The IR-cut filter changes over automatically, color mode holds to 0.01 lux at F2.0, and with IR active it records at 0 lux in full darkness.
How is it powered on site?
Through PoE: the network cable from your PoE switch delivers power and video together, so there is no power adapter at the camera. That makes multi-camera rollouts across shops, schools and compounds faster and cheaper to cable.
Can it be installed outdoors in the rain?
Yes, the housing is IP67 rated against dust and water, so uncovered walls, gates and carports are fine. Aim it precisely with pan 0-360, tilt 0-80 and rotate 0-360 degrees, and digital defog helps in haze or dusty wind.
Is it usable where internet bandwidth is limited?
Yes. Ultra 265 and H.265 compression shrink the 1080p stream, with bit rate adjustable from 128 kbps to 6144 kbps. Dual streams let the NVR record full quality while remote viewers pull a light sub stream at D1 or 640x360.
Does the IPC3612LB-SF28(40)-A need an NVR, and will it work with a non-Uniview recorder?
Yes, plan on an NVR: this page lists no MicroSD slot or edge storage, so the camera itself does not record. It supports ONVIF Profile S and T plus RTSP, which most third-party NVRs and VMS software use for live view and recording; motion events and IR control are fully handled on Uniview NVRs and may be limited on other brands. Tell us your NVR model and we will confirm before you order.
How big an NVR hard disk do I need for IPC3612LB-SF28(40)-A cameras?
At 2048 Kbps, a common setting for 1080P with H.265 or Ultra 265, each camera writes about 22.1 GB per day, so 8 cameras recording continuously for 30 days need about 5.3 TB (a 6 TB disk). At the 6144 Kbps maximum the same 8 cameras need about 16 TB for 30 days. Motion-only recording and Ultra 265 bring this down.
Can the IPC3612LB-SF28(40)-A record sound?
No. Built-in mic, built-in speaker and audio I/O are all N/A on this model, so nothing picks up sound and the official datasheet has no audio functions at all. If you need audio at a counter or entrance, choose a model with a built-in mic, such as the IPC3612LB-AF28K-DL.
Why does the IPC3612LB-SF28(40)-A send motion alerts at night when nobody is there?
This model has plain motion detection only, with no human or vehicle filtering, so anything that changes the image can trigger it: insects drawn to the IR LEDs, spider webs on the dome, rain, moving shadows or headlights. Draw the detection area only over the path or door, lower the sensitivity, keep the camera away from other lamps and clean the dome during maintenance. For people-only alerts, record on a Uniview NVR that has its own smart analysis.
What PoE switch and cable do I need for IPC3612LB-SF28(40)-A cameras?
Any IEEE 802.3af (or 802.3at) PoE port works: the camera draws at most 5.0 W, so 8 cameras need about 40 W of PoE budget. The network port is 10/100 Mbps, so a Fast Ethernet PoE switch is enough; use a gigabit uplink to the NVR for larger systems (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 (Ø5.5 mm plug) where there is no PoE.
