The Uniarch Uho-B2D-M3F3(4)D is a 3MP Wi-Fi bullet camera built for sites where running a network cable isn't practical. It powers from a standard DC12V adapter and connects over built-in 2.4GHz Wi-Fi — no PoE switch or NVR cabling required, just a power outlet nearby. It combines dual-light illumination (20m IR + 10m warm light, switchable), ultra motion detection, two-way audio (mic and speaker), and an IP67 metal-and-plastic body rated for −30°C to 60°C. It is offered with two fixed lenses: 2.8mm (M3F3D, wider view) or 4.0mm (M3F4D, longer reach).
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Rentals & sites without spare network runsNo PoE switch or NVR cable run needed — plug into any nearby outlet and join the site Wi-Fi. Move it to a new spot without touching a cable.
Home gates & yardsThe warm light switches on at night for full-color footage of visitors, and two-way audio lets you speak to them directly from the app.
Warehouse & site perimetersIP67 body and −30 to 60 °C rating survive rain, dust and heat outdoors, day after day. M3F4D watches long fence lines.
Checking in from your phonePair it with the Uniarch APP for live view, push alerts and playback from anywhere — no NVR required for basic remote viewing.
Local backup you controlMicroSD edge storage up to 512GB keeps footage on the camera itself — no monthly cloud subscription required to have a recording.
Quick DIY installsNo electrician or cable-puller needed — mount, plug in, and connect to Wi-Fi from the app in a few minutes.
Not the right pick if you need…
- PoE power — this camera has no PoE port, it needs its own outlet with the included DC12V adapter
- Always-on color night vision — full color only shows when the warm light is on (manual or event-triggered); the discreet IR-only mode is black & white
- Vandal resistance — the datasheet lists IP67 ingress protection only, no IK impact rating
- A one-time fixed focal length choice at purchase — the lens is fixed (2.8 or 4.0 mm), chosen when you order, not zoomable on site
- Rock-solid connectivity regardless of Wi-Fi signal — performance depends on the strength of the site's 2.4GHz Wi-Fi signal at the mounting spot

Invisible infrared — discreet black & white night vision
Smart IR up to 20 m (66 ft.) at 850 nm. The camera watches without lighting up the scene — nothing shows it is recording.
WARM LIGHT MODE
Visible warm light — full-color footage and active deterrence
Warm light up to 10 m (33 ft.) keeps faces and clothing colors visible at night — and tells visitors and intruders the area is watched.

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.

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 Uho-B2D-M3F3(4)D from its official datasheet: 3 MP, 2.8 mm or 4.0 mm F1.6 fixed lens, 2.4 GHz Wi-Fi, dual light (20 m IR + 10 m warm light), two-way audio, DC 12 V at max. 5.7 W, IP67.
Who it is for
- Homes with a gate or front door to answer — Mic and speaker let you talk to a visitor from the app, and at night the warm light shows the visitor in color within 10 m — about the distance of a gate seen from the house wall.
- Small shops and kiosks without network cabling — It joins the shop's 2.4 GHz Wi-Fi and records to a microSD card of up to 512 GB; the visible light and a spoken warning through the speaker deter people loitering after closing time.
- Rentals and holiday homes — No PoE switch or recorder to install, up to 32 users can be set up, and tampering alarm warns if the camera is covered or turned away.
- Buyers on a budget who still want color at night — The 3 MP version uses the lowest bit rate of the B2D pair (max. 2048 Kbps), which is easier on a weak Wi-Fi link and on the microSD card than the 5 MP Uho-B2D-M5F3(4)D.
Where and how to install
- Check the Wi-Fi at the mounting spot — The antenna is built in, so there is nothing to point or extend. Before drilling, stand at the spot with a phone on the same 2.4 GHz network and play a video; if it stutters, add a mesh node or extender, or use the RJ45 port with a cable.
- Keep the subject inside the warm-light range — Mount at about 2.5–3.5 m. Color at night only reaches 10 m, and a face is identifiable at 4.7 m (2.8 mm) or 6.7 m (4.0 mm), so aim at a door or gate within that distance; beyond 10 m the night image is black-and-white IR up to 20 m.
- Light and reflections — Keep walls, eaves and gutters out of the frame: both IR and warm light reflect off them and wash out the picture. Do not aim the warm light at a neighbor's windows or a road, and keep other lamps away from the camera to attract fewer insects.
- Power and cable tail — 12 V DC ±25% (9–15 V) through a Ø5.5 mm plug, max. 5.7 W. Keep the adapter indoors or in a weatherproof box; put the power and RJ45 tail in the TR-JB05-A-IN junction box or seal it with the TR-A01-IN cable gland.
- Brackets — Wall: directly or on TR-JB05-A-IN. Pole: TR-UP06-B-IN, or TR-UP06-C-IN-V2 together with the junction box. Corner: TR-UC08-C-V2. The 3-axis mount also allows ceiling or eave mounting; keep the speaker side unobstructed so visitors can hear you.
2.8 mm or 4.0 mm: what you actually see
Same 3 MP sensor, different fixed lens chosen at order time. The 4.0 mm sees about 1.4× farther and covers about 70% of the width. At 10 m it puts about 121 pixels on each meter of the scene versus about 83 for the 2.8 mm. Night color reaches 10 m with either lens, so the 4.0 mm's longer identify distance (6.7 m) still falls inside the warm-light range.
| M3F3D · 2.8 mm | M3F4D · 4.0 mm | |
|---|---|---|
| Horizontal view angle | 108.5° | 87.3° |
| Width covered at 5 m | 13.9 m | 9.5 m |
| Width covered at 10 m | 27.8 m | 19.1 m |
| Pixels per meter at 10 m | 83 | 121 |
| Identify a stranger's face up to | 4.7 m | 6.7 m |
| Recognize someone you know up to | 9.3 m | 13.3 m |
| Observe what is happening up to | 18.7 m | 26.7 m |
| Detect that something is there up to | 46.7 m | 66.7 m |
| Night: color (warm light) / IR | 10 m / 20 m | 10 m / 20 m |
- Pick 2.8 mm (M3F3D) for a porch, a shop front or a small yard: from 5 m away it covers 13.9 m of width.
- Pick 4.0 mm (M3F4D) for a gate 5–7 m away where you want the face: identifiable at 6.7 m, and still in color at night.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = horizontal pixels ÷ width at 10 m; distances are the manufacturer's DORI figures from the official datasheet.

3MP Dual-Light Wi-Fi Camera FAQ — Uho-B2D-M3F3(4)D
What does dual-light night vision actually give me?
You choose per scene: invisible 850 nm IR up to 20 m for discreet black-and-white footage, or warm white light up to 10 m that keeps faces and clothing colors visible — and openly tells people the area is watched. Color starts at just 0.003 lux thanks to the F1.6 lens.
Can I install it without a PoE switch or network cabling?
Yes. The camera joins your Wi-Fi network and powers from a nearby outlet, so there is no PoE switch and no LAN run. With its IP67-rated housing it mounts outdoors on walls or eaves — practical for shops, homes and small warehouses without structured cabling.
Does it support two-way audio?
Yes — two-way audio is supported with G.711U/A compression at 64 Kbps, so you can hear the scene and answer a visitor or warn off an intruder remotely. Audio detection and a tampering alarm can trigger events alongside standard and ultra motion detection.
Which lens option fits my site, 2.8 mm or 4.0 mm?
The 2.8 mm lens sees 108.5° horizontally with DORI detection to 46.7 m and identification to 4.7 m — right for compounds, rooms and yards. The 4.0 mm option tightens to 87.3° and pushes detection to 66.7 m, identification to 6.7 m — better for driveways, gates and passages.
What resolution does it record, and does it need an NVR?
The main stream is 3 MP (2304×1296) at up to 25 fps, with a lighter sub stream for remote viewing; compression is Ultra 265/H.265/H.264 at 128–2048 Kbps. Recordings can go to a MicroSD card inside the camera, so it runs standalone — an NVR is optional, not required.
How far from the router will the Uho-B2D-M3F3(4)D keep a stable Wi-Fi connection?
It depends on walls and interference more than on metres, so test at the mounting spot rather than relying on a distance. The camera uses 2.4 GHz 802.11b/g/n with a built-in antenna and needs at most 2048 Kbps for its main stream; if a phone on the same network plays video smoothly at that spot, the camera will usually be stable. Thick concrete, metal doors and roller shutters are the usual problem; a mesh node or extender, or the RJ45 port with a cable, solves it.
How do I stop the Uho-B2D-M3F3(4)D from alerting on trees, rain and passing headlights?
Use ultra motion detection rather than plain motion detection for phone alerts, because plain motion reacts to any pixel change such as leaves, rain or light sweeping across the scene. Draw the detection area over the path or gate only, leaving out trees, the road and the sky, then lower sensitivity step by step until alerts drop. At night insects near the lamps are a common trigger, so wipe the front glass and remove cobwebs during maintenance.
Can several family members or staff use the Uho-B2D-M3F3(4)D at the same time?
Yes. It supports up to 32 users with 2 levels, administrator and common user, through the Uniarch app or the Uniarch client. Keep the administrator account for the owner and give others common-user access, so staff can watch and receive alerts without changing settings, and access can be removed later without resetting the camera. Remember that each person watching live uses part of the Wi-Fi and internet upload.
What happens to the Uho-B2D-M3F3(4)D when the power goes off?
It switches off: there is no battery, and it runs only from its 12 V DC adapter. Recordings already on the microSD card are kept, and when power returns it restarts and rejoins the Wi-Fi by itself once the router is back. Where outages are common, put the router and the camera adapter on a small UPS; size it for the camera's maximum of 5.7 W.
Can the Uho-B2D-M3F3(4)D handle direct sun, heavy rain and dusty sites?
Yes, within its ratings: the body is IP67 (dust-tight and protected against water) and works from −30 °C to 60 °C at up to 95% humidity, non-condensing. The weak points are installation details, not the body: seal the power and RJ45 tail, keep the adapter out of the rain, and on a sun-baked wall add a small hood or mount under an overhang so the camera does not sit in full afternoon sun. No IK impact rating is listed, so mount it out of easy reach.
Do I need a cloud subscription to record?
No. Recording to the on-board microSD card works without any subscription. If you want to record to your own NVR or server, check the protocols listed in the specification table (RTSP / ONVIF) or send us the name of your recording software and we will confirm compatibility before you order.
Is the Uho-B2D-M3F3(4)D suitable for watching a farm gate or fence line?
Yes, as long as the gate has a 12 V power point and 2.4 GHz Wi-Fi coverage: the IP67 body is rated for -30 °C to 60 °C, and the 4.0 mm M3F4D identifies a person at 6.7 m and recognizes at 13.3 m (2.8 mm M3F3D: 4.7 m and 9.3 m). At night, IR reaches 20 m and the warm light 10 m for full-color alert video. Choose the 4.0 mm version for a gate further from the camera and the 2.8 mm version for a wide area close by.
How many days of video does a microSD card hold in the Uho-B2D-M3F3(4)D?
At the maximum stated bit rate of 2048 Kbps with continuous 24-hour recording, the Uho-B2D-M3F3(4)D writes about 22.1 GB per day, so a 128 GB card holds about 5.8 days, 256 GB about 11.6 days and the maximum supported 512 GB card about 23 days. Setting a lower bit rate (the range starts at 128 Kbps) or recording on motion events only makes the card last longer.
What is the difference between the Uho-B2D-M3F3(4)D and the Uho-B2D-M5F3(4)D?
Both are Uniarch Wi-Fi bullet cameras with dual light and audio, offered in 2.8 mm and 4.0 mm lens versions; the practical difference is resolution, 3MP on the Uho-B2D-M3F3(4)D versus 5MP on the Uho-B2D-M5F3(4)D. Pick the Uho-B2D-M3F3(4)D (2304×1296 at up to 25 fps) for standard entrance and yard coverage, and the M5 version when you want more pixels to zoom into recorded footage.
Can the Uho-B2D-M3F3(4)D be viewed on a PC or connected to a third-party recorder?
Yes for PC viewing: besides the mobile APP, the Uho-B2D-M3F3(4)D works with the Uniarch client and a web browser (plug-in live view on IE 10+, Chrome 45+, Firefox 52+, Edge 79+). For integration it supports RTSP with authentication plus an API and SDK. ONVIF is not listed in its specification, so confirm compatibility before planning to record it on a non-Uniarch NVR.
