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

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.
