The Uniarch IPC-D122-PF28K is a 2MP fixed dome network camera with a metal vandal-resistant body (IK10) and IP67 outdoor rating. It provides up to 30 m of smart infrared night vision, MicroSD edge storage, and powers over a single PoE cable or DC 12V, with a −30 °C to 60 °C working range. It carries a fixed 2.8 mm lens only — there is no alternate lens option for this model.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Hallways & corridorsThe low-profile dome shape sits flush on a ceiling and blends into the surroundings — less obtrusive than a bullet camera in indoor spaces.
Schools & transit stationsIK10 vandal-resistant housing withstands impact and tampering in high-traffic public areas.
Loading docks & site entrancesIP67 body and −30 to 60 °C rating survive rain, dust and heat outdoors, day after day.
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.
Quick retrofits & pole/ceiling installsOne PoE cable does power + video — no electrician needed on site, quick to install.
Not the right pick if you need…
- Full-color night vision — this is IR-only, night video is black & white, not color
- Audio recording or two-way talk — no built-in mic or speaker on this model
- Wi-Fi — this is a wired RJ45 camera
- Zoom or an alternate lens option — this model has a fixed 2.8 mm lens only
- 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 | 101.1° |
|---|---|
| 5 m16 ft | 12.2 m39.9 ft |
| 10 m33 ft | 24.3 m79.7 ft |
| 15 m49 ft | 36.5 m120 ft |
| 20 m66 ft | 48.6 m159 ft |
| 30 m98 ft | 72.9 m239 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-D122-PF28K from its official datasheet: 2 MP at up to 25 fps, fixed 2.8 mm F2.1 lens (101.1°), 30 m Smart IR, IK10 metal dome, IP67, PoE at max. 3.3 W.
Who it is for
- Schools, clinics and public corridors — The IK10 metal-and-plastic dome resists knocks and tampering where people can reach it, and the 101.1° view covers a hallway or waiting room from the ceiling.
- Offices, shops and receptions on a budget — A discreet ceiling camera that draws max. 3.3 W on IEEE 802.3af PoE; Ultra 265 keeps recordings small on a shared NVR disk.
- Covered outdoor areas — IP67 and −30 °C to 60 °C let it work under porches, car ports and loading-dock canopies, with 30 m of invisible 850 nm IR at night.
- Sites that want video only — There is no microphone, which suits offices or clinics where recording conversations is not wanted; MicroSD and ANR keep a local copy if the network drops.
Where and how to install
- Ceiling first — The mount is 2-axis (pan 3°–360°, tilt 0°–75°) with no rotate axis, so it is made for ceilings. On a wall, use the TR-WM03-D-IN-V2 wall bracket (or TR-JB07/WM03-G-IN-V2 with a junction box) so the dome hangs as it would from a ceiling and the picture stays level.
- Height and faces — Mount at about 2.5–3.5 m. Faces are identifiable only up to 4.5 m with this 2.8 mm lens, so put the camera close to the door or counter you care about, not in the middle of a large room.
- Backlight at glass doors — This model has DWDR (digital), not the 120 dB true WDR of models such as the IPC-B312-ADZK. Do not aim it straight at a bright glass entrance; look along the corridor or from the street side inward, and use BLC or HLC where some backlight cannot be avoided.
- Outdoors: rain, joint and surge — The dome is IP67, but the RJ45 and 12 V tail is not: use the TR-JB03-G-IN junction box (wiring from behind) and the TR-A01-IN gland. Add the HS-205S sunshade where rain hits the bubble directly. Surge protection is 4 kV; on long outdoor runs add a surge protector and earthing.
- High ceilings and poles — Under a high ceiling, drop it on the TR-SE24-IN (200 mm) or TR-SE24-A-IN (500 mm) pendant pole with the TR-CM24-IN bracket (indoor), or flush-mount it with the TR-FM116 in-ceiling bracket. Outside, use TR-UC08-C-V2 for building corners and TR-UM06-E-IN for slanted surfaces.
2.8 mm fixed lens: what you actually see
This dome comes only with a 2.8 mm lens. It is built for coverage, not distance: about 12.2 m of width at 5 m, but only about 79 pixels per meter at 10 m, so faces are identifiable to 4.5 m and known people recognizable to 9.0 m. For a gate or a long corridor where faces matter farther away, look at the motorized IPC-D312-ADZK dome instead; for more detail with the same wide view, the 4 MP IPC-D124-PF28K.
| PF28K · 2.8 mm | |
|---|---|
| Horizontal view angle | 101.1° |
| Width covered at 5 m | 12.2 m |
| Width covered at 10 m | 24.3 m |
| Pixels per meter at 10 m | 79 px/m |
| Identify a stranger's face up to | 4.5 m |
| Recognize someone you know up to | 9.0 m |
| Observe what is happening up to | 18.0 m |
| Detect that something is there up to | 45.0 m |
- Good fit: a room, shop floor or corridor up to about 9 m deep, where you want to see who is there and what they do.
- For face evidence, add one dome right above the entrance or till so people pass within 4.5 m.
- At night the IR reaches 30 m, so the 45.0 m detect figure applies after dark 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 PoE Dome Camera FAQ — IPC-D122-PF28K
How far does the IPC-D122-PF28K see at night?
Smart IR at 850 nm covers up to 30 m in full darkness, invisible to the eye. The 2.8 mm lens spans a 101.1° horizontal view, with DORI figures of 45 m to detect, 18 m to observe, 9 m to recognize and 4.5 m to identify — sized for lobbies, corridors and shop entrances.
What protocol do I use to connect it to a third-party NVR?
It supports ONVIF Profile S, Profile G and Profile T plus an API, so it registers on most third-party recorders and VMS platforms. RTSP, RTMP, HTTP/HTTPS, NTP, DDNS and QoS are in the protocol stack, and video comes in Ultra 265, H.265 or H.264.
Can it keep recording during a network outage?
Yes — the MicroSD slot takes cards up to 512 GB, and ANR (automatic network replenishment) means the NVR pulls the missing segment from the card once the link returns, so the timeline on the recorder has no gap. Useful where power or network is unstable.
Is this dome vandal-proof and usable outdoors?
Yes on both. The housing carries an IK10 impact rating — it takes deliberate knocks in schools, prisons or bus stops — and IP67 sealing against dust and heavy rain. Power arrives by PoE over the same network cable, keeping ceiling and soffit installs clean.
What resolution and bandwidth should I plan per channel?
The main stream runs 1080p (1920×1080) at up to 25 fps with a D1/640×360 sub stream for live view. Bit rate is adjustable from 128 to 6144 Kbps; using Ultra 265 or H.265 keeps a typical channel at the low end, saving both uplink bandwidth and NVR disk.
The IPC-D122-PF28K image turns white or hazy at night. How do I fix IR glare in the dome?
This is usually IR light bouncing inside the bubble or off something close. Remove the protective film, make sure the foam ring around the lens sits flat against the bubble after you adjust the angle, and do not touch the inside of the bubble. Keep ceilings, walls and eaves out of the picture, and clean dust or cobwebs off the outside of the bubble regularly.
Which MicroSD card should I use in the IPC-D122-PF28K, and how many days will it hold?
Use up to 128 GB to be safe: the datasheet feature list says 128 GB while its spec table says 512 GB, so confirm with us before buying a larger card. At 2048 Kbps continuous (a common 1080P H.265 setting) the camera writes about 22.1 GB per day, so a 128 GB card holds about 5.8 days; at the 6144 Kbps maximum, about 1.9 days. Motion-only recording stretches this considerably in quiet rooms.
Does the IPC-D122-PF28K record sound?
No. The datasheet lists no built-in mic, no speaker and no audio input, so it records video only. If you need sound at a counter, choose a model with a built-in mic, such as the Uniarch IPC-B242-ADF28(40)K-WP or IPC-B312-ADZK, and check local rules on recording audio first.
How do I cut false motion alarms on the IPC-D122-PF28K?
This model offers plain motion detection only, with no human or vehicle filter, so anything that changes the picture can trigger it. Draw the detection area only over floors and doorways, lower the sensitivity, mask moving signs, screens or trees, and keep insects away from the IR by cleaning the bubble. If you need alarms only for people, use a model with human-based intrusion and cross line, such as the IPC-B312-ADZK.
How many IPC-D122-PF28K domes can a PoE switch or PoE NVR power?
Power is rarely the limit: at max. 3.3 W each, eight domes need only 26.4 W, so an 8-port 60 W switch such as the Uniarch SW-2110-LP runs all of its ports. Any IEEE 802.3af port works, and the camera port is 10/100 Mbps, so Fast Ethernet is enough. Keep each Cat5e or Cat6 run under 100 m, or use a 12 V DC adapter with a Ø5.5 mm plug where there is no PoE.
