The Uniarch Uho-B1R-M2F3(4)-A is a 2MP 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 ultra motion detection (human/vehicle aware), Smart IR night vision up to 30m, a built-in mic, and an IP67 metal-and-plastic body rated for −30°C to 60°C. It is offered with two fixed lenses: 2.8mm (M2F3, wider view) or 4.0mm (M2F4, 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 & yardsUltra motion detection tells people from passing cars and stray animals, cutting false phone alerts to what actually matters.
Warehouse & site perimetersIP67 body and −30 to 60 °C rating survive rain, dust and heat outdoors, day after day. M2F4 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
- Full-color night vision — this is IR-only, night video is black & white, not color
- Two-way talk — it has a built-in mic but no speaker
- 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

Who uses it, where it goes and how to install it
Written for the Uho-B1R-M2F3(4)-A from its official datasheet: 2 MP, 2.8 mm or 4.0 mm fixed lens, 2.4 GHz Wi-Fi, 30 m Smart IR, human/vehicle detection, DC 12 V at max. 3.6 W, IP67.
Who it is for
- Homes where no network cable can be pulled — It joins the home 2.4 GHz Wi-Fi and only needs a 12 V DC adapter nearby; the 4.0 mm version still identifies a face at 6.7 m at the front gate.
- Yards, farms and plots with dark corners — Its 30 m Smart IR reaches farther than that of the Uho-B2R-M2F3(4) bullet, and ultra motion detection alerts on people and vehicles rather than on every animal or moving branch.
- Landlords and temporary sites — No PoE switch or recorder is needed: footage goes to a microSD card of up to 512 GB in the camera, and the camera can be moved to a new outlet later without re-cabling.
- Owners who want to hear what happens — The built-in mic records sound with the video, and high-decibel detection can send an alert when there is a sudden loud noise such as shouting or banging.
Where and how to install
- Test the Wi-Fi at the exact spot first — Stand where the camera will go with a phone connected to the same 2.4 GHz network and play a video. If it stutters, move the router, add a mesh node or extender, or use the camera's RJ45 port with a cable instead. Each concrete or brick wall, metal door or roller shutter between camera and router cuts the signal sharply.
- Height and aim — Mount at about 2.5–3.5 m with a shallow downward tilt, aimed at the gate or door people walk through. For a recognizable face keep that point within 4.5 m (2.8 mm) or 6.7 m (4.0 mm).
- Power: keep the adapter and plug dry — The camera takes 12 V DC ±25% (9–15 V) through a Ø5.5 mm plug and draws at most 3.6 W. Keep the adapter indoors or in a weatherproof box, and put the power and RJ45 tail in the TR-JB05-A-IN junction box or seal it with the TR-A01-IN cable gland. For long low-voltage runs use thicker cable so the voltage at the camera stays above 9 V.
- Brackets — Wall: directly or on the TR-JB05-A-IN junction box. 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 (pan 0–360°, tilt 0–90°, rotate 0–360°) also allows ceiling or eave mounting.
- Night view and weather — Keep walls, eaves and gutters out of the picture or the 30 m IR reflects back and washes out the night image. The body is IP67 and rated −30 °C to 60 °C with 4 kV surge protection; still avoid pointing the lens straight at the sky or sun.
2.8 mm or 4.0 mm: what you actually see
Same 2 MP sensor, different fixed lens chosen at order time. The 4.0 mm sees about 1.5× farther but covers about two-thirds of the width. At 10 m it puts about 120 pixels on every meter of the scene versus about 76 for the 2.8 mm. Both have the same 30 m IR at night.
| M2F3 · 2.8 mm | M2F4 · 4.0 mm | |
|---|---|---|
| Horizontal view angle | 103.0° | 77.5° |
| Width covered at 5 m | 12.6 m | 8.0 m |
| Width covered at 10 m | 25.1 m | 16.1 m |
| Pixels per meter at 10 m | 76 | 120 |
| Identify a stranger's face up to | 4.5 m | 6.7 m |
| Recognize someone you know up to | 9.0 m | 13.3 m |
| Observe what is happening up to | 18.0 m | 26.7 m |
| Detect that something is there up to | 45.0 m | 66.7 m |
- Pick 2.8 mm (M2F3) for a porch, a small yard or a parking spot right in front of the house: from 5 m away it covers 12.6 m of width.
- Pick 4.0 mm (M2F4) for a gate or driveway 5–7 m away or a long fence: a face is still identifiable at 6.7 m.
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.

2MP Wi-Fi Bullet Camera FAQ — Uho-B1R-M2F3(4)-A
Do I need a PoE switch or network cable to install it?
No. It connects over Wi-Fi and takes power from a nearby outlet — no PoE switch, no LAN cable run. Installation comes down to mounting the bracket, plugging in power and joining your network, which makes it practical for shops and houses where cabling is difficult.
How far can it see at night?
Smart IR reaches 30 m (98 ft) at 850 nm — invisible light, so nothing shows the camera is recording. Minimum illumination is 0.01 lux in color and 0 lux with IR on; the IR-cut filter switches between day and night mode automatically.
Which lens should I order, 2.8 mm or 4.0 mm?
The 2.8 mm version covers 103° horizontally — good for yards and rooms — with DORI detection at 45 m and identification at 4.5 m. The 4.0 mm narrows to 77.5° but stretches detection to 66.7 m and identification to 6.7 m, better for gates, corridors and driveways.
Does it record sound, and can I talk back through it?
It has a built-in microphone and records audio in G.711U/A at 64 Kbps, but this model is listen-only — there is no two-way talk. High-Decibel detection can raise an alert when the mic picks up loud sounds such as shouting or breaking glass.
Is it suitable for outdoor use, and how does it cut false alarms?
Yes — the housing is rated IP67 against dust and heavy rain. Ultra motion detection classifies events by human body and vehicle, so waving branches and stray animals trigger far fewer alerts. Footage is saved to a MicroSD card in the camera, with Ultra 265/H.265 keeping files small.
How far from the Wi-Fi router can I mount the Uho-B1R-M2F3(4)-A?
There is no fixed number: it depends on walls and interference more than metres. The camera uses 2.4 GHz 802.11b/g/n with 20 MHz channels and needs at most 2048 Kbps for its main stream, so a stable link matters more than a fast one. Test at the mounting spot with a phone: if video plays smoothly there, the camera will usually be fine; if not, add a mesh node or extender, or connect the RJ45 port with a cable.
What Wi-Fi security does the Uho-B1R-M2F3(4)-A support, and is my video protected?
The datasheet lists 64/128-bit WEP and WPA-PSK/WPA2-PSK for Wi-Fi; WPA3 is not listed, so set the router to WPA2-PSK or WPA2/WPA3 mixed mode rather than WPA3-only. On the network side it supports TLS 1.2, strong-password enforcement, digest authentication for HTTP and RTSP, IP address filtering and exportable operation logs. Change the default password at setup and keep the firmware up to date.
Can my family or staff watch the Uho-B1R-M2F3(4)-A on their own phones?
Yes. The camera supports up to 6 users with 2 levels, administrator and common user, and is viewed through the Uniarch app or the Uniarch client. Keep one administrator account for yourself and give others common-user access instead of sharing the admin password, so you can remove someone later without resetting the camera.
What happens to the Uho-B1R-M2F3(4)-A during a power cut?
It stops recording: there is no battery, and it runs only from its 12 V DC adapter. What was already saved on the microSD card stays there, and when power returns the camera restarts and rejoins the Wi-Fi by itself, provided the router is also back on. In areas with frequent outages, put the router and the camera adapter on a small UPS; at max. 3.6 W the camera adds very little load.
Can I black out a neighbor's window or yard in the Uho-B1R-M2F3(4)-A picture?
Not on the camera alone: the datasheet lists privacy mask as supported only through an NVR. Used stand-alone with the app and microSD card, the practical fix is placement: aim lower or turn the camera so the neighbor's property is out of the frame, and choose the 4.0 mm lens if the 103.0° view of the 2.8 mm takes in too much. If you will record to an NVR, tell us its model and we will check masking before you order.
Can the Uho-B1R-M2F3(4)-A alert me to a loud noise, not just movement?
Yes. Besides ultra motion detection for people and vehicles, it has high-decibel detection, which triggers when the sound picked up by the built-in mic passes a loud level, for example shouting, banging or breaking glass near the camera. Start with a high threshold near roads or machinery and lower it until normal background noise no longer triggers alerts.
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.
How many days of recording does a microSD card hold in the Uho-B1R-M2F3(4)-A?
At the maximum video bitrate of 2048 Kbps with continuous 24-hour recording, the Uho-B1R-M2F3(4)-A writes about 22.1 GB per day (2.048 Mbps × 86,400 s ÷ 8). That gives roughly 5.8 days on a 128 GB card, 11.6 days on 256 GB and 23 days on the maximum supported 512 GB card. Lowering the bitrate within its 128–2048 Kbps range extends this proportionally; at 1024 Kbps the recording time doubles.
Is the Uho-B1R-M2F3(4)-A suitable for a farm gate or an entrance far from the house?
Yes, if your 2.4 GHz Wi-Fi reaches the gate and you can bring 12 V DC power there. The camera has no battery or 4G, so it needs a DC 12 V (±25%) supply through its Ø5.5 mm plug and a 2.4 GHz router or access point within range. The body is IP67 with 4 KV surge protection and works from -30 °C to 60 °C; to identify a person, mount it within 4.5 m (2.8 mm lens) or 6.7 m (4.0 mm lens) of where people stop.
What is the difference between the Uho-B1R-M2F3(4)-A bullet and the Uho-D1R-M2F3-A dome?
Both are 2MP Wi-Fi cameras with 30 m IR, but the Uho-D1R-M2F3-A is a dome rated IK10 for impact resistance, while the Uho-B1R-M2F3(4)-A is a bullet with no IK rating listed. The bullet is offered with a 2.8 mm or 4.0 mm lens, while the dome is listed as the M2F3 (2.8 mm) version. Choose the dome where the camera can be reached or struck, such as low walls or shop entrances; choose the bullet for higher mounting or when you need the 4.0 mm lens for longer reach.
Does the Uho-B1R-M2F3(4)-A work with 5 GHz Wi-Fi or with an NVR?
It connects only on 2.4 GHz (2.4–2.4835 GHz, IEEE 802.11b/g/n, WPA-PSK/WPA2-PSK), so your router must have its 2.4 GHz band enabled; 5 GHz is not supported. For recording beyond the microSD card, the spec lists RTSP, ONVIF authentication (WSSE and Digest), API/SDK integration and ANR network storage, and privacy masks are applied only through an NVR. Everyday viewing is through the app or the Uniarch client.
