The Uniarch IPC-B234-AF40-ECO is a 4MP fixed bullet network camera from the Entry Series IR line, built in a larger IP67 outdoor housing. It provides up to 30 m of smart infrared night vision, accurate human body detection 2.0, PoE single-cable power, and an NDAA-compliant build for −30 °C to 60 °C. It carries a fixed 4.0 mm lens (75° view) for medium-range coverage with a sharper 4MP image.
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 in sharp 4MP detail, and the built-in mic records what is said at the counter. The 4.0 mm lens covers a full 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. The larger housing detects movement up to 90.0 m away along fence lines.
Residential compoundsHuman body detection 2.0 raises alerts for people, not for stray animals or moving branches.
Procurement-sensitive sitesNDAA-compliant build for buyers with government or institutional procurement rules. Ultra 265 compression keeps recordings small on the NVR despite the higher 4MP resolution.
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 at 4.0 mm, no optical zoom
- MicroSD card recording — Edge Storage is N/A, it records to an NVR instead
- 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 | 74.6° |
|---|---|
| 5 m16 ft | 7.6 m25.0 ft |
| 10 m33 ft | 15.2 m50.0 ft |
| 15 m49 ft | 22.9 m75.0 ft |
| 20 m66 ft | 30.5 m100.0 ft |
| 30 m98 ft | 45.7 m150 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 IPC-B234-AF40-ECO from its official datasheet: 4 MP, fixed 4.0 mm lens (74.6°), 30 m smart IR, built-in mic, PoE (802.3af) at max. 3.1 W, IP67.
Who it is for
- Entrances, gates and driveways — 4 MP on a 4.0 mm lens identifies a face up to 9.0 m and recognizes a known person up to 18.0 m, so one camera covers the approach to a door or gate.
- Homes and residential compounds — 850 nm smart IR gives black-and-white night video up to 30 m without lighting up the area, and human body detection 2.0 is meant to alert on people rather than animals or branches.
- Installers handing over to Spanish or Russian speaking clients — The web interface has 4 languages (English, Russian, Spanish, Vietnamese), 3 user levels and HTTPS, and the camera draws at most 3.1 W, so small PoE NVRs and switches power a full set easily.
- Yards, warehouses and fence lines — The larger IP67 B2xx housing works from −30 °C to 60 °C and detects movement up to 90.0 m along a wall or fence.
Where and how to install
- Height and angle — Mount at about 2.5–3.5 m with a shallow downward tilt. Lower is easier to tamper with; much higher shows the top of heads instead of faces.
- Aim faces into 9.0 m — Point it at a door, gate or corridor where people walk toward the camera and pass within 9.0 m, the identify distance. Beyond that you see what happens, but not reliably who it is.
- Keep the IR beam clear — Do not tuck it under eaves or let a wall, gutter or the bracket appear at the edge of the picture: IR reflects back and the night image turns white or foggy. Remove spider webs near the lens; they glow in IR and trigger motion.
- Bright backgrounds — WDR is digital (DWDR), with BLC and HLC. Do not aim from inside at a bright glass door, or straight at the sun or headlights; place it so the light comes from behind or beside the camera.
- Weather, cable and surge — The body is IP67, the RJ45 joint is not: put it in the TR-JB05-A-IN junction box with a TR-A01-IN cable gland, or seal it. Surge protection is 4 KV; on poles or long outdoor runs add a PoE surge protector and earthing.
- Brackets — Wall: directly or on the TR-JB05-A-IN box. Pole: TR-UP06-B-IN, or TR-UP06-C-IN-V2 with the junction box. Building corner: TR-UC08-C-V2. The 3-axis mount levels the picture on uneven walls.
The 4.0 mm lens: what you actually see
This model comes only with a 4.0 mm lens (74.6°). From 5 m it covers 7.6 m of width and from 10 m about 15.2 m, with about 168 pixels per meter at 10 m on its 2560-pixel-wide image. For a wider 2.8 mm view, the smaller B1xx IPC-B134-AF28(40)-ECO is offered with both lenses; the 2 MP IPC-B232-AF40-ECO uses the same housing.
| AF40 · 4.0 mm | |
|---|---|
| Horizontal view angle | 74.6° |
| Width covered at 5 m | 7.6 m |
| Width covered at 10 m | 15.2 m |
| Pixels per meter at 10 m | 168 px/m |
| Identify a stranger's face up to | 9.0 m |
| Recognize someone you know up to | 18.0 m |
| Observe what is happening up to | 36.0 m |
| Detect that something is there up to | 90.0 m |
| Night range in IR (black and white) | 30 m |
- Good fit: a gate, entrance or driveway where people come within 9.0 m, and a scene up to about 15 m wide at 10 m distance.
- Along a fence or wall it shows that someone is there up to 90.0 m, but recognizing who it is needs them within 18.0 m.
- Covering a whole room from a corner close up? A 2.8 mm camera inside plus this one on the entrance works better.
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.

4MP IR Bullet Camera FAQ — IPC-B234-AF40-ECO
How far does the night vision of the IPC-B234-AF40-ECO reach?
Its single 850 nm smart IR illuminator reaches 30 m in total darkness with black-and-white footage. Thanks to the 4MP sensor, DORI figures for the 4.0 mm lens are strong: detect a person at 90 m, observe at 36 m, recognize at 18 m and identify at 9 m.
Does it show color at night?
This is an IR-only model: in darkness the IR-cut filter switches to black and white, and the 850 nm light stays invisible so the camera records discreetly. With ambient light it holds color down to 0.01 lux through the F2.0 lens. Need color at night? Choose the dual-light version.
How is it powered and can it stay outdoors?
PoE delivers power and video over one network cable, cutting cabling cost along fences and driveways. The IP67 housing withstands dust and heavy rain, the bracket adjusts 360° pan and 90° tilt, and the model is NDAA compliant for tenders that require it.
Can it pick up audio and detect people?
Yes. The built-in microphone records G.711U/G.711A audio with the video, and audio detection raises an event on loud noise. Human body detection 2.0 filters people from swaying vegetation and animals, so alerts are more reliable than with basic motion detection alone.
What resolution does it record and how much bandwidth does it use?
Main stream records 4MP (2560×1440) at up to 25 fps, or 3MP/1080p at 30 fps if you prefer smoother motion. Encoding is Ultra 265, H.265 or H.264 with dual streams, and bit rate adjusts from 128 to 6144 Kbps to balance quality against bandwidth and storage.
Does the IPC-B234-AF40-ECO record to a microSD card, and how much NVR disk does it need?
No: Edge Storage is N/A in the datasheet, so it records to an NVR or VMS. At the maximum 6144 Kbps continuous recording uses about 66.4 GB per day, about 2 TB per camera for 30 days. Assuming 4096 Kbps with Ultra 265 it is about 44.2 GB per day, or about 1.33 TB per camera for 30 days; event-only recording reduces it further.
Will the IPC-B234-AF40-ECO work with a Hikvision, Dahua or other non-Uniarch NVR?
For live view and recording, usually yes: it supports ONVIF Profile S and Profile T plus RTSP, and an API and SDK are listed for software integration. Set the camera's IP in the NVR's network range, then add it as an ONVIF device with the camera's own user name and password. Human body detection 2.0 events may not pass to other brands, so use motion-based recording there; send us your NVR model and we will confirm before you order.
Why is the night picture of my IPC-B234-AF40-ECO white, foggy or full of false alarms?
Almost always it is IR bouncing back from something close to the lens: an eave, wall, gutter, the bracket, or a spider web. Re-aim so nothing near the camera is in the picture, keep the front window clean and remove webs. Smart IR lowers IR power on close objects to limit overexposure, and alerts based on human body detection 2.0 instead of plain motion cut alarms from insects and rain.
IPC-B234-AF40-ECO or the mini IPC-B134-AF28(40)-ECO: what is the difference?
Both are 4 MP IR bullets with human body detection 2.0, and the 4.0 mm versions see the same scene. This B2xx model has the larger graphene and plastic housing (196.5 × 73.0 × 72.9 mm, 0.22 kg), and its datasheet adds HTTPS, SSL/TLS and an API. The B1xx mini is smaller and is also offered with a wider 2.8 mm lens; this model has no 2.8 mm version.
Can I give the owner's staff limited access to the IPC-B234-AF40-ECO and view it securely from outside?
Yes. It supports up to 32 users in 3 levels: administrator, operator and common user, so the installer can keep the admin account and give staff view-only or operator access. HTTPS and SSL/TLS are listed, plus strong-password enforcement and exportable operation logs. For remote viewing use the APP or Uniarch client listed in the datasheet, ideally through the NVR, rather than opening the camera's ports directly to the internet.
