The Uniarch IPC-B122-APF28(40)K is a 2MP mini fixed bullet network camera. It provides up to 30 m of smart infrared night vision, MicroSD edge storage, powers over a single PoE cable, and carries an IP67 outdoor rating with a −30 °C to 60 °C working range. It is offered with two fixed lenses: 2.8 mm (AF28, wider view) or 4.0 mm (AF40, 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. AF28 covers the whole shop floor from a corner.
Home gates & yardsSmart IR turns on at night for discreet black-and-white night vision — the camera watches without lighting up the scene.
Warehouse & site perimetersIP67 body and −30 to 60 °C rating survive rain, dust and heat. AF40 watches long fence lines.
Sites needing local backupA built-in MicroSD slot keeps footage on the camera itself — useful as a backup even where an NVR is also recording.
Small offices & receptionUltra 265 compression keeps recordings small — more days of footage on the same NVR disk.
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…
- Full-color night vision — this is IR-only, night video is black & white, not color
- 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 | AF28 · 101.1° | AF40 · 83.7° |
|---|---|---|
| 5 m16 ft | 12.2 m39.9 ft | 9.0 m29.4 ft |
| 10 m33 ft | 24.3 m79.7 ft | 17.9 m58.8 ft |

| 30 m98 ft | 72.9 m239 ft | 53.7 m176 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 Uniarch IPC-B122-APF28(40)K from its own specifications: 2 MP, 2.8 mm or 4.0 mm fixed lens, 30 m Smart IR, MicroSD slot, PoE or 12 V DC.
Who it is for
- Installers on a tight budget — A 2 MP bullet that takes either PoE (IEEE 802.3af) or a 12 V DC adapter and draws at most 3.2 W, so it fits small PoE switches and sites where some runs have no PoE.
- Small shops and kiosks without an NVR — The MicroSD slot records on the camera itself, and the built-in mic adds sound at the counter. Unlike the cheaper ECO models (B132-ECO), this one keeps the card slot.
- Homes, yards and gates — Invisible 850 nm Smart IR up to 30 m gives black-and-white night video without lighting up the yard, so nothing shows the camera is recording.
- Warehouses and site perimeters — IP67 body and a −30 °C to 60 °C working range for outdoor walls and poles; the 4.0 mm version recognizes a known person up to 12.9 m along a fence or driveway.
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: 4.5 m with the 2.8 mm lens, 6.4 m with the 4.0 mm lens.
- Keep IR from bouncing back — Do not mount tight under eaves or next to a wall, gutter or pole that sits inside the picture: the IR reflects back and turns the night image white. Keep branches and cobwebs away from the lens.
- Weather, cable joint and surge — The body is IP67, but the RJ45 and 12 V tail is not: put it in the TR-JB05-A-IN junction box and seal the cable entry with the TR-A01-IN 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 the junction box is used; outside building corners: TR-UC08-C-V2. The 3-axis mount (tilt 0–90°, rotate 0–360°) lets you level the picture on a sloped wall.
- Power and cable — Use Cat5e or Cat6 copper up to 100 m from the PoE switch or NVR. Where there is no PoE, use a 12 V DC adapter with a Ø5.5 mm plug (12 V ±25%).
2.8 mm or 4.0 mm: what you actually see
Same 2 MP sensor, different lens. The 2.8 mm covers about 12.2 m of width at 5 m, the 4.0 mm about 9.0 m. In return the 4.0 mm reaches about 1.4× farther for faces (6.4 m against 4.5 m) and puts about 107 pixels on each meter at 10 m against about 79 for the 2.8 mm.
| APF28K · 2.8 mm | APF40K · 4.0 mm | |
|---|---|---|
| Horizontal view angle | 101.1° | 83.7° |
| Width covered at 5 m | 12.2 m | 9.0 m |
| Width covered at 10 m | 24.3 m | 17.9 m |
| Pixels per meter at 10 m | 79 px/m | 107 px/m |
| Identify a stranger's face up to | 4.5 m | 6.4 m |
| Recognize someone you know up to | 9.0 m | 12.9 m |
| Observe what is happening up to | 18.0 m | 25.7 m |
| Detect that something is there up to | 45.0 m | 64.3 m |
- Pick 2.8 mm for a shop floor, a small yard or a door seen from close: from 5 m it covers 12.2 m of width.
- Pick 4.0 mm for a gate, driveway or corridor 5–7 m away: faces stay identifiable to 6.4 m and known people recognizable to 12.9 m.
- At night the IR reaches 30 m, so beyond that distance the detect figures (45.0 m / 64.3 m) apply only where there is other lighting.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = horizontal pixels ÷ width at 10 m; face distances are the manufacturer's DORI figures.

2MP IR Bullet Camera FAQ — IPC-B122-APF28(40)K
How far can the IPC-B122 see at night?
Smart IR reaches up to 30 m (98 ft) at 850 nm — invisible light, so nothing shows the camera is recording. With IR on it works at 0 Lux, and it holds color down to 0.02 Lux (F2.1, AGC on). The IR-cut filter switches day/night automatically, with auto or manual IR control.
Should I choose the 2.8 mm or the 4.0 mm lens?
The 2.8 mm gives a 101.1 degree horizontal view with DORI detection to 45.0 m and identification at 4.5 m — pick it for entrances and close, wide scenes. The 4.0 mm narrows to 83.7 degrees but detects to 64.3 m and identifies at 6.4 m — better for corridors, fence lines and driveways.
Is it suitable for outdoor use, and how is it powered?
Yes — the housing is IP67 rated against dust and water, so it handles rain-exposed walls and poles. Power and video run over PoE, meaning one Ethernet cable from your PoE switch covers both, which keeps installation cost down on multi-camera CCTV jobs. The bracket adjusts pan 0–360, tilt 0–90, rotate 0–360 degrees.
Does it record audio?
Yes, it has a built-in mic and compresses audio in G.711U or G.711A at 64 Kbps, and audio detection can raise events on sound. Note it is listen-only: two-way audio is not available on this model, so choose another unit if you need to talk back through the camera.
What resolution and bandwidth should I plan for?
The main stream runs 1080P (1920x1080) at up to 25 fps, with a D1 sub stream for live walls, both as dual streams. Bitrate is adjustable from 128 to 6144 Kbps, and Ultra 265, H.265 and H.264 with U-code trim storage and bandwidth. Motion detection, 4 privacy masks and 8 ROI areas round out the basics.
Will the IPC-B122-APF28(40)K work with a Hikvision, Dahua or other non-Uniview NVR?
Usually yes for live view and recording: it supports ONVIF Profile S, G and T plus RTSP, which most third-party NVRs and VMS software use. Its own events are only motion and audio detection, and those alarms may not pass to every brand. Tell us your NVR model and we will confirm before you order.
How many days can the IPC-B122-APF28(40)K record on a MicroSD card?
At the maximum 6144 Kbps with continuous recording it writes about 66.4 GB per day, so a 128 GB card lasts about 1.9 days and a 512 GB card about 7.7 days. At 2048 Kbps, a 128 GB card lasts about 5.8 days and a 512 GB card about 23 days; Ultra 265 and motion-only recording stretch this further. The official datasheet lists 512 GB in its specification table but 128 GB in its feature list, so for cards above 128 GB confirm with us first.
Does the IPC-B122-APF28(40)K detect people, or will trees and cats trigger alerts?
It has plain motion detection and audio detection only, with no human or vehicle classification, so moving branches, animals, rain and insects in the IR can trigger it. Reduce false alerts by drawing tight detection areas, lowering sensitivity and keeping plants out of the frame. If people-only alerts matter, the IPC-B132-AF28(40)-ECO has Human body detection 2.0 and the IPC-B124-APF28(40)K adds Ultra motion detection.
IPC-B122-APF28(40)K or IPC-B132-AF28(40)-ECO: which 2 MP bullet should I buy?
Pick the B122 if you need the MicroSD slot, a 12 V DC option or the widest view (101.1° with the 2.8 mm lens). Pick the B132-ECO if every camera goes to a PoE NVR and you want Human body detection 2.0; it is PoE-only, has no card slot and its 2.8 mm view is narrower at 87.8°, but it identifies faces a little farther (5.1 m against 4.5 m). Both have 30 m IR, a built-in mic and IP67.
How do I view the IPC-B122-APF28(40)K on my phone or PC?
The page lists the Uniarch app and the Uniarch client for PC; with a Uniarch or Uniview NVR you normally add the NVR to the app instead of each camera. For direct access, the web interface works without a plug-in in Chrome 57+, Firefox 58+ and Edge 16+. The web interface is in English only, and up to 32 user accounts can be created with administrator or common-user rights.
