The Uniarch Uho-B2D-M5F3(4)D is a 5MP 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 (M5F3D, wider view) or 4.0mm (M5F4D, 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. M5F4D 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

Dual Light: two ways to see the night

Switchable Auto/Manual, or auto-switch when a preset is triggered — set it per site.

IR MODE

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.

Who uses it, where it goes and how to install it

Written for the Uho-B2D-M5F3(4)D from its official datasheet: 5 MP (2880 × 1620), 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 that want faces and number plates, not just shapes — 5 MP identifies a face at 6.3 m (2.8 mm) or 9.0 m (4.0 mm), about a third farther than the 3 MP Uho-B2D-M3F3(4)D, and at night the 4.0 mm identify distance still sits inside the 10 m warm-light range.
  • Shops and offices that need to zoom into recordings — At 10 m the 2.8 mm version still puts about 127 pixels on each meter of the scene, so a wide shop-front view can be zoomed in playback to read details; two-way audio lets staff answer the door remotely.
  • Sites with good Wi-Fi coverage — At full 5 MP the camera can stream up to 6144 Kbps, three times the 3 MP model's maximum, so it suits homes and shops where the router or a mesh node is close and the signal is strong.
  • Rentals and small properties without a recorder — It records to a microSD card of up to 512 GB, supports up to 32 users, and raises a tampering alarm if someone covers or turns the camera.

Where and how to install

  • Strong Wi-Fi first, then the mount — A 5 MP stream needs a better link than a 2 or 3 MP one. Test at the spot with a phone on the same 2.4 GHz network; if video stutters, add a mesh node or extender close to the camera, use the RJ45 port with a cable, or lower the bit rate and use Ultra 265 or H.265 to cut the load.
  • Height and distance to the target — Mount at about 2.5–3.5 m with a shallow tilt. Aim at the door or gate people walk through, within 6.3 m (2.8 mm) or 9.0 m (4.0 mm) for an identifiable face, and within 10 m if you want that face in color at night.
  • Light, reflections and neighbors — Keep walls, eaves and gutters out of the frame so IR and warm light do not reflect back. Do not aim the warm light at neighbors' windows or the road, and keep the camera away from other lamps to attract fewer insects.
  • Power, cable tail and weather — 12 V DC ±25% (9–15 V) through a Ø5.5 mm plug, max. 5.7 W. The body is IP67, −30 °C to 60 °C, with 4 kV surge protection, but the adapter must stay dry and the power/RJ45 tail belongs in the TR-JB05-A-IN junction box or behind 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 (pan 0–360°, tilt 0–90°, rotate 0–360°) also allows ceiling or eave mounting.

2.8 mm or 4.0 mm: what you actually see

Same 5 MP sensor, different fixed lens chosen at order time. The 4.0 mm sees about 1.4× farther and covers about 73% of the width. At 10 m it puts about 175 pixels on each meter of the scene versus about 127 for the 2.8 mm. With the 4.0 mm, a face is identifiable at 9.0 m, just inside the 10 m warm-light range, so it can still be seen in color at night.

  • Pick 2.8 mm (M5F3D) for a porch, a shop front or a yard: from 5 m away it covers 11.3 m of width, and the 5 MP detail still identifies a face at 6.3 m.
  • Pick 4.0 mm (M5F4D) for a gate or driveway 7–9 m away: a face is identifiable at 9.0 m, in color at night within the 10 m warm-light range.

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.

5MP Dual-Light Wi-Fi Camera FAQ — Uho-B2D-M5F3(4)D

What detail can I expect from the 5MP sensor?
The main stream runs 2880×1620 (5 MP) at up to 25 fps. With the 2.8 mm lens, DORI figures are 63 m detect / 12.6 m recognize / 6.3 m identify; the 4.0 mm lens stretches these to 90 m / 18 m / 9 m — solid pixel density for entrances, yards and parking areas.
How does night vision work on this camera?
It carries two illuminators. Invisible 850 nm Smart IR reaches 20 m for discreet black-and-white recording; a warm white light reaches 10 m to keep footage in full color and visibly deter intruders. Sensitivity is 0.003 lux in color (F1.6) and 0 lux with IR on.
Does it work without a PoE switch, and can it go outdoors?
Yes to both. It connects over Wi-Fi and powers from a nearby outlet, so no PoE switch or LAN cabling is needed. The bullet housing is rated IP67 against dust and heavy rain, so it mounts on exterior walls, gates and eaves as an outdoor waterproof camera.
What alarms and audio functions does it offer?
Two-way audio (G.711U/A, 64 Kbps) lets you hear the scene and speak back. On the event side it runs motion detection, ultra motion detection, audio detection and a tampering alarm that fires if someone covers or blocks the lens.
How much bandwidth and storage should I budget?
Bit rate is adjustable from 128 to 6144 Kbps, so a full-quality 5 MP stream stays near 6 Mbps and can be tuned much lower with Ultra 265 and U-code. Dual streams keep remote viewing light, and recordings can be written to a MicroSD card in the camera.
Will watching the Uho-B2D-M5F3(4)D on my phone use a lot of mobile data?
It can, if you watch the full 5 MP main stream: at the 6144 Kbps maximum that is about 2.8 GB per hour of live viewing (6144 Kbps × 3600 s ÷ 8). The camera has dual streams, and the sub stream runs at up to 720P, so choose the lower-quality or sub-stream view on mobile data and switch to the main stream only when you need detail. Short checks and alert clips use far less than continuous live viewing.
My router uses WPA3. Will the Uho-B2D-M5F3(4)D connect, and how is it secured?
WPA3 is not listed: the datasheet gives 64/128-bit WEP and WPA-PSK/WPA2-PSK. Set the 2.4 GHz network to WPA2-PSK or WPA2/WPA3 mixed (transition) mode so the camera can join, and avoid WEP, which is easy to break. Also change the default password at setup, give other people common-user accounts instead of the admin login, and keep the firmware up to date.
Can I blank out a neighbor's window or garden in the Uho-B2D-M5F3(4)D image?
Not from the camera alone: privacy mask is listed as supported only through an NVR. When the camera is used stand-alone with the app and microSD card, solve it with placement: tilt down or turn the camera so the neighbor's property is out of frame, and choose the 4.0 mm lens (79.0°) instead of the 2.8 mm (97.0°) if the wide view takes in too much. Also keep the warm light from shining onto the neighbor's property.
Does the Uho-B2D-M5F3(4)D keep recording during a power cut?
No. It has no battery and runs only from its 12 V DC adapter, so it stops until power returns; footage already on the microSD card is kept. When power comes back it restarts and rejoins the Wi-Fi on its own once the router is up again. If outages are common, put the router and the camera adapter on a small UPS sized for the camera's maximum of 5.7 W plus the router.
Will the warm light on the Uho-B2D-M5F3(4)D attract insects and cause false alerts?
Some, as with any light beside a lens; insects and the cobwebs that follow them are a common cause of night-time alerts. Keep the warm light in Auto or event-triggered mode rather than always on, use ultra motion detection instead of plain motion detection for alerts, keep the camera away from other outdoor lamps, and wipe the front glass and nearby webs during routine maintenance.
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-M5F3(4)D suitable for watching a long driveway or a farm gate?
Yes, choose the 4.0 mm version (M5F4D) for this job. It identifies a person up to 9.0 m, recognizes up to 18.0 m and detects up to 90.0 m, versus 6.3 m, 12.6 m and 63.0 m for the 2.8 mm version, which is better for wide, close areas. At night, IR reaches 20 m and the warm light 10 m, so full-color night images are limited to the first 10 m from the camera.
What power adapter does the Uho-B2D-M5F3(4)D need?
A 12 V DC adapter with a Ø5.5 mm coaxial plug; a 12 V 1 A unit is enough for one camera. Maximum consumption is 5.7 W, which is 5.7 W ÷ 12 V ≈ 0.48 A, and the input tolerates DC 12 V ±25%. If you power four cameras from one supply, budget 4 × 5.7 W = 22.8 W, about 1.9 A at 12 V, plus some margin.
What is the difference between the Uho-B2D-M5F3(4)D and the Uho-B2D-M3F3(4)D?
The main difference is resolution: the Uho-B2D-M5F3(4)D is 5MP (2880×1620 at up to 25 fps), while the Uho-B2D-M3F3(4)D is 3MP; both are Wi-Fi dual-light cameras with audio. Pick the 5MP model when you want more pixels on a wide scene, such as reading details at the edge of a yard. Note that the 5MP main stream can use up to 6144 Kbps, so it needs a stronger Wi-Fi link when recording at maximum quality.
Which Wi-Fi network and software does the Uho-B2D-M5F3(4)D work with?
It connects only to 2.4 GHz Wi-Fi (IEEE 802.11b/g/n, 20 MHz channel) with WEP or WPA-PSK/WPA2-PSK security; 5 GHz networks are not supported. It is managed with the APP or the Uniarch client, and live view in a web browser needs a plug-in (IE 10+, Chrome 45+, Firefox 52+, Edge 79+). For integration it lists RTSP (with authentication), API and SDK, plus a 10/100 Mbps RJ45 port.
